To calculate the Compound Annual Growth Rate in Excel, there is a basic formula =((End Value/Start Value)^(1/Periods) -1. And we can easily apply this formula as following:

1. Select a blank cell, for example Cell E3, enter the below formula into it, and press the Enter key. See screenshot:

=(C12/C3)^(1/(10-1))-1

Note: In the above formula, C12 is the cell with end value, C3 is the cell with start value, 10-1 is the period between start value and end value, and you can change them based on your needs.

2. In some cases, the calculation result may not format as percentage. Please keep selecting the calculation result, click the Percent Style button  on the Home tab to change the number to percentage format, and then change its decimal places with clicking the Increase Decimal button  or Decrease Decimal button . See screen shot:

Actually, the XIRR function can help us calculate the Compound Annual Growth Rate in Excel easily, but it requires you to create a new table with the start value and end value.

1. Create a new table with the start value and end value as the following first screen shot shown:

Note: In Cell F3 enter =C3, in Cell G3 enter =B3, in Cell F4 enter =-C12, and in Cell G4 enter =B12, or you can enter your original data into this table directly. By the way, you must add a minus before the End Value.

2. Select a blank cell below this table, enter the below formula into it, and press the Enter key.

=XIRR(F3:F4,G3:G4)

3. For changing the result to percentage format, select the Cell with this XIRR function, click the Percent Style button  on the Home tab, and then change its decimal places with clicking the Increase Decimal button  or Decrease Decimal button . See screen shot:

Quickly save the CAGR table as a mini template, and reuse with only one click in future

It must be very tedious to refer cells and apply formulas for calculating the averages every time. Kutools for Excel provides a cute workaround of AutoText utility to to save the range as an AutoText entry, which can remain the cell formats and formulas in the range. And then you will reuse this range with just one click.

To calculate the Average Annual Growth Rate in excel, normally we have to calculate the annual growth rates of every year with the formula = (Ending Value - Beginning Value) / Beginning Value, and then average these annual growth rates. You can do as follows:

1. Besides the original table, enter the below formula into the blank Cell C3 and, and then drag the Fill Handle to the Range C3:C11.

=(C4-C3)/C3

2. Select the Range D4:D12, click the Percent Style button  on the Home tab, and then change its decimal places with clicking the Increase Decimal button  or Decrease Decimal button . See screenshot:

3. Average all annual growth rate with entering below formula into Cell F4, and press the Enter key.

=AVERAGE(D4:D12)

Up to now, Average Annual Growth Rate has been calculated and shown in the Cell C12.
