Excel Help - Average rate of change

Hi,

In cell M1, enter this formula

=AVERAGE(B2:L2/A2:K2-1)

For checking, i entered the formula =AVERAGE(B3:L3) in cell M2. As you can see, the answer is the same.

Hope this helps.

Hello Omilio,

I'm Ibhadighi and I'd happily help you with your question. In this forum, we are Microsoft consumers just like yourself.

To calculate the average rate of change in Excel as a percentage between each month, you can use the following formula in Row 1, Column M:

=AVERAGE((B1-A1)/A1, (C1-B1)/B1, (D1-C1)/C1, ..., (L1-K1)/K1) * 100

This formula calculates the rate of change between each pair of months (like February to January, March to February, and so on), averages these rates, and then multiplies by 100 to convert it into a percentage.

Here's a step-by-step breakdown:

1. Calculate Rate of Change: (B1-A1)/A1 calculates the rate of change from January to February. Similarly, (C1-B1)/B1 calculates it for February to March, and so on.
2. Average the Rates: AVERAGE(...) takes all these individual monthly rates of change and calculates their average.
3. Convert to Percentage: Multiplying by 100 converts the average rate into a percentage.
4. Enter the Formula: Place this formula in Cell M1 and it will give you the average rate of change across the months in percentage.

Please remember to adjust the formula if your data starts from a different row or column.

I hope this helps,
