### How to Calculate Compounded Annual Growth Rate (CAGR)

When you’re doing financial analysis, it’s helpful to add some context to growth numbers. That’s where using a Compounded Annual Growth Rate (CAGR) is very useful. Rather than saying a company has grown 50% over 10 years, you could say instead that they’ve grown by an average of 4.1% every year. It also gives you a percentage to use going forward if you need to forecast what you expect next year’s growth to be since you’ll have a starting point. The CAGR effectively tells you what the average growth rate has been during that period of time. It doesn’t mean that it’s grown every year by that rate, but that on average, it has risen by that amount.

## Using Amazon as an example

To calculate CAGR what you need to know are just two things: the total growth and the duration of time. Let’s use Amazon’s sales as an example. In 2018, total revenues for the year reached \$233 billion. Back in 2010, the company had \$34 billion in sales, meaning that Amazon’s revenues have grown by 585% during that time. Impressive, no doubt, but it doesn’t tell us how well it’s typically done on a yearly basis. This is where we calculate CAGR to help determine what the average growth was over that time.

From 2010 to 2018, that’s eight years that it took for sales to grow by 585%. To calculate CAGR, we use the following equation:

(Current Year Amount / Base Year Amount) ^ ( 1 / # of Years)

In the Amazon calculation, it would look as follows:

(233/34) ^ (1/8) – 1 = 27%

What this tells us is that Amazon for the past eight years has averaged an annual growth rate of around 27.2%. There’s an easy way we can prove this out. Starting with our base year of 2010, take the sales amount of \$34 billion and multiply it by (1 + growth rate) each and every year. Here is how the level of growth looks like year over year:

 Year Prior Year Revenue Growth Current Year Revenue 2010 \$34, 000 2011 \$34,000 27.2% \$43,248 2012 \$43,248 27.2% \$55,011 2013 \$55,011 27.2% \$69,973 2014 \$69,973 27.2% \$89,006 2015 \$89,006 27.2% \$113,215 2016 \$113,215 27.2% \$144,008 2017 \$144,008 27.2% \$183,177 2018 \$183,177 27.2% \$233,000

As you can see, if we assume a 27.2% growth rate each and every year, we arrive to the same end value. Although Amazon did not grow at this consistent of a pace, using CAGR helps to average the results over a period of time.

Whether you’re looking at sales, dividends, or any other kind of growth, using CAGR can be a very useful tool in putting into context just how the strong the rate of growth was.

## Using CAGR to help forecast

Having CAGR is also useful if we want to forecast out future sales. Let’s assume that Amazon will have a more modest rate of growth for the next 10 years. That rather than a CAGR of 27.2%, it’ll be closer to 20% instead. Now, we can create a forecast around that and assume that sales will grow by 20% each year (on average) for the next 10. Our forecast would look as follows:

 Year Prior Year Revenue Growth ProjectedRevenue 2019 \$233,000 20% \$279,600 2020 \$279,600 20% \$335,520 2021 \$335,520 20% \$402,624 2022 \$402,624 20% \$483,149 2023 \$483,149 20% \$579,779 2024 \$579,779 20% \$695,734 2025 \$695,734 20% \$834,881 2026 \$834,881 20% \$1,001,857 2027 \$1,001,857 20% \$1,202,229 2028 \$1,202,229 20% \$1,442,675

To prove this out, what we can do is the following: 233,000 x (1.20^10) = 1,442,675

Based on these projections, we would expect amazon to hit the one trillion dollar mark in sales by the end of 2026. Maintaining a CAGR of 20%, however, will be difficult, even for a company like Amazon. Although all it takes is some big acquisitions and it will be well on its way!

### How to Copy and Paste in Excel (5 Different Ways)

Knowing how to copy and paste is one of the most basic things you can learn to do in Excel. And while everyone is familiar with doing it, you might be surprised that there are several ways to do it, some more common than others.

## Using Ctrl + C and Ctrl + V

This is definitely one of the more common ways that people are familiar with copying and pasting. It simply involves selecting the cells you want to copy, pressing Ctrl + C, and then selecting where you want to paste them, and then clicking Ctrl+ V.

## Using the mouse to right-click copy and paste

Also another one of the more common ways to copy and paste. Here you’ll select what you want to copy, right-click and select copy. Then, select where you want to paste the data, then click right-click and paste. This way avoids having to use the keyboard but requires pulling up the menu with two mouse clicks.

## Using the mouse and keyboard together

Hold down Ctrl while selecting the cell that you want to copy and drag it to your destination. Then, release the mouse button and your data will be copied.

Note, if you release the Ctrl button first, and then release the mouse button, then you will have moved the cell (the equivalent of Ctrl + X, Ctrl+V) instead of copying it. The advantage of this method is you don’t have to click as much and it’s useful if you’re quickly copying within the same area. The disadvantage is this method won’t work if you want to copy the data onto another tab or workbook.

## Using right-click to copy and paste

Select a cell and hover over the borders until you see a crosshair appear. Then hold down on right click and drag it to where you want to copy it to, then release the button. You’ll be left with many options, including copying the cell or moving it. Technically this involves a second click, but you only have to bring up the menu once.

## Using VBA

This is obviously not a method I’d suggest if you wanted to just copy cells over one time unless it was part of a larger macro you’re working on. But to copy data over in VBA it’s a fairly straightforward process that includes just one line of code:

Range(“A1”).copy Range(“A2”)

The first range (A1) is the cell you’re copying and in the above example, A2 is where you’re pasting it to.

### 4 Biggest Annoyances of Pivot Tables and How to Fix Them

Pivot Tables are great tools, especially for quickly summarizing data and allowing you to avoid entering in complex formulas to do so. However, they aren’t perfect and definitely have their quirks about them.

Here are four things that most users aren’t crazy about, and how to fix them.

## The layout

When you create a pivot table it puts the table into a layout that is less than optional for spreadsheets. It’s not only hard to use for any other purpose, but it’s also not the easiest format to read. I always prefer a format that resembles more of a spreadsheet itself, in a grid format, without the indented rows.

To change the format, go to the Design section of the PivotTable Tools and select Report Layout and select Show in Tabular Form

This is what the pivot table looks like after the change:

This might still look a little cluttered, but what you can also do is get rid of any subtotals by simply right-clicking on the Total and unchecking the Subtotal button, and then it’s a bit cleaner:

The table still needs a little work for me, and that brings me to the second issue:

## Labels do not repeat

You’ll notice that the value in the date field only shows up once. And so if I had many entries for a given date there would be a lot of blank values in the first column. Again, this is not ideal for a large data set and so this is where I’d like to make a change as well.

I go back to the Report Layout section, except this time I select the option to Repeat All Item Labels

Now my table looks like this:

This is what I would hope the pivot table looks like right off the bat. Unfortunately, Microsoft does not agree and opts for the indented version with subtotal at every section and no repeating values.

But that’s not all, there’s another little nuance you may notice when it comes to pivot tables:

## Formatting won’t stay consistent

You’ll notice that in the sales data, I have a total of 2158 for January 4th. Anytime you’re dealing with numbers in the thousands, you’ll probably want some formatting that shows a comma in there just to make the numbers more readable. However, if you simply select the entire column and change the formatting, it will revert back to the default if you refresh the pivot table after adding more data.

What you need to do is actually change the field settings. To do this, right click on any of the numbers in that column and select Value Field Settings.

From there, select Number Format and then select the format you want it to show up as. Doing this will ensure the formatting won’t change when you refresh the data.

Tip: if you routinely make these changes like I do, you may want to check out the add-in I created which will make all these changes for you at the click of a button.

This brings me to the fourth most irritating item when it comes to pivot tables:

## GETPIVOTDATA

By default, when you reference a number in a pivot table, it will auto-generate a formula called GETPIVOTDATA. In most cases, you probably won’t find this helpful, especially if you just want to reference some pivot table values elsewhere in your workbook. If you just want to reference cell E4 and copy the formula down, you’ll need to adjust the pivot table settings, as the GETPIVOTDATA will make it a bit painful to accomplish this.

Back under the PivotTable Tools section, select the Analyze tab and on the Options menu on the left-hand side, uncheck where it says Generate GetPivotData

Now you can reference values from a pivot table the way you would any other cell in your workbook.

If you have any other frustrations with pivot tables, please share them in the comments.

### 5 Useful Excel Shortcuts That Are Underutilized

There are a lot of ways you can speed up data entry and analysis in Excel, and while most people know about copying and pasting and how to undo actions, there are some useful ones that many users aren’t familiar with.

This list will go over five lesser-known, but useful shortcuts.

1. CTRL + 1 : Formatting cells.

If you find yourself changing the formatting of cells often then using this shortcut could help save some time rather than right clicking format cells. It may not be a huge time saver but if you’re not using the mouse then it’s an easier way to access that menu.

2. CTRL + F1 : Toggle the ribbon

When you’re working with a lot of data often times you’ll need just a bit more space, and hiding the ribbon can help give you see more rows on your page. You can also double-click on the active tab’s name and it will accomplish the same result.

3. CTRL + ~ : Show formulas

If you’re editing a spreadsheet and want to quickly find where there are formulas versus which cells are hard-coded, this is an easy way to show you what is actually entered in the cell, as opposed to what the end value is. The ~ button is normally located next to the 1 on your keyboard.

4. CTRL + ] and CTRL + [  : Showing dependents and precedents

These shortcuts are useful because if you click on a cell that has a formula you can see if there are other cells that are dependent on the cell for inputs somewhere else, or which cells feed into this one. CTRL + [ will show you which cells the active cell depends on, and where its inputs come from, while CTRL + ] will show you if the active cell is used in calculations elsewhere.

You can hit tab to cycle through all the cells that have been highlighted.

It will not show you all the cells if the related cells span multiple tabs, but it can be helpful when looking at formulas and inputs in all other cases.

5. ALT + F1 : Insert a chart

This shortcut can allow you to quickly launch a chart based on the data that you’ve selected. This again may not be a big time saver, but if you’re on a different tab or

### Loan and Savings Formulas – PV, FV, and PMT

In a previous post I covered my amortization/depreciation template.

Here I will cover how to do present value and future value calculations that are used in that template. I will start with a savings example. Suppose I want to accumulate \$500,000 in savings at the end of 25 years after making monthly payments. I will assume an average interest rate of 3%. My inputs will be as follows:

Present Value (current savings) = 0
Future value (target savings) = \$500,000
Number of payments (n) = 300 (25 years * 12 monthly payments a year)
Interest Rate (i) = 0.25% (3%/12 months)

## Payment  Calculation

To determine the size of the payment I need to be making to ensure I meet my target calculation, I will need to use the PMT (payment) formula. With the above inputs, my formula will look as follows:

=-PMT(0.0025,300,0,500000)

I enter a negative before the formula to ensure my value will be positive. This yields a result of \$1,121.06. I could add an additional argument to say that the payments are at the beginning of the period as opposed to the end. All I need to do is add a another argument with the number 1, as shown below:

=-PMT(0.0025,300,0,500000,1)

The result would be \$1,118.26; a difference of less than \$3 a payment.

## Future Value Calculation

I can test my calculations by now doing a future value calculation. My inputs remain the same, except now I have a payment amount.  The future value formula will look as follows:

=FV(0.0025,300,-1121.06,0)

I have made the payment amount negative so that the formula results in a positive number. My future value equals 500,001.53, confirming that I will reach the target amount with this payment amount. I could also change the payment number from 300 to 150, to determine how much I will have amassed halfway:

=FV(0.0025,150,-1121.06,0)

This tells me I will have a balance of \$203,723.81 after 150 payments.

I’ll switch over to another example now. Let’s assume you have a mortgage and want to know what your balance is today. You can use a similar calculation, except this time you will have a negative present value and don’t know your future value (today’s value). Suppose a mortgage of \$250,000, a 30 year mortgage with monthly payments (n=360), an interest rate of 5% and payments of \$1,342.05 (this can be calculated in much the same way as the payment calculation was done for the first example).

My inputs are as follows (assume I want to know the balance halfway through the mortgage, after payment 180):

Present Value (mortgage amount): \$250,000
Number of Payments (n) = 180 (15 years * 12 monthly payments a year)
Interest Rate (i) = 0.4167% (5%/12 months)
Payment = \$1,342.05

The formula is as follows:

=FV(0.004167,180,1342.05,-250000)

Again you will notice the present value amount is negative here. This is because this is the amount owing. If this was the same sign as the payment amount the balance would increase rather than decrease. This calculation tells my the mortgage balance after 180 payments, or halfway through the mortgage would be \$169,709.77. You may notice slightly different amounts because of the interest rate you use. In the above example I rounded to 0.004167 however if you reference the cell that has the interest rate calculation rather than a hard-coded number you will get a more accurate result.

## Present Value Calculation

I will move on now to a present value calculation. In this example, I want to determine what mortgage amount can be afforded based on a specific monthly payment. Suppose I want the monthly payment to be \$2,000; the term to again be 30 years; the interest rate to still be 5%. With these inputs I can determine what mortgage amount I can afford based on those assumptions. My formula will be as follows:

=PV(0.004167,360,-2000,0)

In the formula above I again set the payment amount to a negative so that the formula gives me a positive number. The result is a value of \$372,563.23.

When doing these calculations you are always better off referencing formulas for interest rate calculation as opposed to hard-coded numbers. As you will notice, even a slight difference in the interest rate can have a big impact on your result, especially when dealing with a large number of payments. I have hard-coded examples in all of the examples here only for illustrative purposes but in practice I would recommend avoiding hard-coding an interest rate.

### Using Summation Formulas (SUM, SUMIF(S), SUBTOTAL)

I have saved this sample file here if you would like to look at the data set and have a closer look at how the formulas work.

In this post I will cover some simple summation formulas and when best to use them. I have a sample data set that has stores, customers, and total sales.

## Summing Total Sales

If I just wanted to total all the sales then the SUM function would accommodate this easily. There is even a summation button on the Excel ribbon to easily do this.

It is on the right hand side of the Home tab in the Editing group. It will try to determine which cells you want to sum but you can change this range to what you need.

Since my values are in column C my formula would be as follows:

=SUM(C:C)

Pretty straightforward, all you need is the column that you want to sum (or specific range if you don’t want everything in the column). This returns the grand total of \$256,129 from my data set. Another way I could find out the total is if I just highlight the entire column.

The sum will show in the bottom right corner of my screen in the status bar.

If I right click on any of this area I get the following menu:

If you didn’t see the sum in your status bar this is where you can add it. In my example I could select Minimum and Maximum and then those values would also be calculated for any range that I highlight and show up in the status bar. This makes it easier if you quickly want to see an average, total, min or max by just highlighting a range without having to type a formula each time.

## Summing Single Store Sales

But now suppose I just wanted to know the sales of Store A. I could filter the data set, select the column, and see the total in the status bar. But that is a bit tedious to repeat each time if I wanted to see sales by each store. In this case, I could use the SUMIF function.

My formula would look like this:

=SUMIF(A:A,”Store A”,C:C)

The first argument, column A, specifies what range I want to look at; the second argument, “Store A”, is what criteria I am looking for; and column C is the final argument, where I want to pull the values from. This formula is saying to look in column A for a value of Store A and add only those related amounts in column C.

Instead of a static reference for Store A I could reference a cell instead, and that would make it easier to apply this formula to multiple stores without having to change the name manually each time.

In the above example assume my store name is in cell E6. If I have the store names going from cell E6:I6 then I could use the following formula:

=SUMIF(\$A:\$A,E6,\$C:\$C)

You will notice I have frozen some of the cells as well. This will allow me to move my formula across without the ranges changing. Below are what my results look like:

## Summing Sales by Customer and Store

Now, consider a scenario where I wanted to do a summary of sales by stores and customers. Here I can use the SUMIFS function (only available to Excel 2007 and newer versions). In the formula below I have stores in cells G12:J12 and customers in cells F13:F16:

=SUMIFS(\$C:\$C,\$A:\$A,E\$12,\$B:\$B,\$F13)

I can copy this formula and it will be updated based on what store and customer intersect at that point. The summary will look as below:

Unlike with the SUMIF function, the first argument here is the range I want to sum, which is column C. The next argument is the range for my first criteria to look up, column A, followed by the criteria I want to match, which in the first formula is cell E12 (Store A). The next two arguments relate to the next criteria range which is column B for the customers and the customer to be matched which in the formula is cell F13 (Customer A).

With the SUMIFS function you can add more criteria than just two. Simply just add another comma and in the next argument specify the range, followed by the criteria. You can keep adding to it as you need.

## How the SUBTOTAL Function Works

Unlike the SUM function, the SUBTOTAL function will perform a calculation based on the filters you have applied (if you have none, it will perform a calculation on all the data in the range). The SUBTOTAL function also has an added argument to tell it what type of calculation it should do:

In the below formula, I am going to total column C again, as I did in the SUM formula initially. However, the additional argument I need in the SUBTOTAL function is defining the calculation. Since I am going to just do a sum, I will set the argument to 9. My formula looks as below:

=SUBTOTAL(9,C:C)

Now, if I were to use filters to show only Store A and Customer A, the SUBTOTAL formula would return the same result as the SUMIFS function did for the intersection of Store A and Customer A.

My formula returns a value of \$10,796 with the above filters, which matches the result from the SUMIFS formula. The SUBTOTAL function is useful when you are always using filters since it will take those filters into account as opposed to the SUM function which will ignore them. If you don’t use filters then it won’t make a difference.

### How to Freeze Panes

Freezing panes in Excel is useful when you want to still see certain rows or columns as you scroll through a large data set. Without doing so you could easily get lost in your data trying to figure out which header or category the value you are looking at belongs to.

Under the View tab select Freeze Panes and if panes are frozen you will see an option to unfreeze panes. Otherwise you can choose to select to freeze panes, freeze top row, or freeze first column. Freeze top row will ensure that row 1 is frozen is you scroll down and ensure you will see your headers. Freezing the first column will make sure column A is always visible as you scroll to the right.

Now but what if you wanted to freeze both rows and columns, or multiple rows or multiple columns? That is where you would just use the regular Freeze Panes option. The key here is to select the correct point of intersection. When you press freeze panes the active cell will determine which rows and columns are frozen. Any rows above and columns to the left of the active cell will be frozen.

For example, if you wanted to freeze just the first row, you would select cell A2. Since there is nothing to the left of it, it would only freeze row 1 which is above.

Above I have highlighted the frozen row as well as which cell I would need to select to achieve that.

If you wanted to freeze just column A, you would select cell B1. Since nothing is above row 1, only column A is to the left of B, so only A would be frozen.

See above for the highlighted column and what cell I would need to select to freeze it.

If you wanted to freeze column A and row 1 then you would need to select cell B2 since row 1 is above that cell and column A is to the left. See below:

Similarly, if you wanted to freeze the first two columns and the first two rows you would select cell C3 – see below for results

### Simple VBA Tricks

A couple quick snippets of VBA code that can help you impress your friends although might not have much real utility.

First up: have Excel speak to you

Application.speech.speak “text”

Where text is what you want Excel to say. Just like with any other code you can of course use variables for this to alternate. You could create a list to cycle through various messages as well.

Another one: opening a URL

The above code will open Google when triggered in the default browser.

### Highlight Alternating Rows or Columns

This post will show you how to create the effect of highlighting alternating rows, which sometimes makes it easier to read a data set.

In order to accomplish this, first select all the cells in the worksheet and then select New Rule under conditional formatting.

For the new rule you will need to select the last option to use a formula. The formula we will need to use is as follows:
=MOD(ROW(A1),2)=1
The MOD function calculates the remainder after division and has two arguments, the number to be divided into, and by what number.
Using ROW(A1) means the reference will change depending on the location of the cell, meaning it will encompass every row in the selection. Using 2 as the divisor will help identify if the row is as odd number or even. If you’d rather highlight columns than rows, use the COLUMN function.
The formula will be true if the remainder is 1, meaning the row is an odd number (e.g. highlighting will start on the first row). If you want highlighting to start from row 2, just change the 1 to a 0, since even rows will have no remainder.
Once the formula is set, click on Format to determine the appearance of the alternating rows.
I select a light blue colour for the alternating rows
After I press OK this is the result of my conditional formatting:
If you don’t want to apply the formatting to all the cells or want to change the range, under conditional formatting select manage rules
There you will see a field where the formatting Applies to. Here you can change the range you want the formatting to apply to.

### Extracting Unique Values

Select the data you want to extract unique values from, and under the Data tab, click on Remove Duplicates.

If the column you select is alongside other data, it will remove those cells as well. If that’s not what you want, I’d recommend copying the column over somewhere else so it is by itself, and then click on the Remove Duplicates button.

For Excel 2003 and older:

Run an Advanced Filter on the column that you want to extract duplicates from, leave the criteria Blank, select Copy to Another Location, and select Unique Records Only.

Note, select the advanced filter option when you are in the sheet you want to extract the values to. For example, if your data is on sheet 1 and you want to extract the duplicates to sheet 2, you need to select advanced filter while you are on sheet 2, otherwise there will be an error.
