Not sure how to do this, If I have a range of numbers, (50, 55, 75, 100)

Assuming you data is in A1:A4, one way:
B2: =A2/A1-1 ==== 10% B3: =A3/A2-1 ==== 36.36% B4: =A4/A3-1 ==== 33.33% If by "average monthly increase" you mean the average of the individual monthly increases, that's just =AVERAGE(B2:B4) === 26.57% OTOH, if by "average monthly increase" you mean the constant monthly increase that, when applied to 50, yields 100 after 3 months, then use =(A4/A1)^(1/3) - 1 == 25.99% In article , vikgarden wrote: Not sure how to do this, If I have a range of numbers, (50, 55, 75, 100) Percentage of increase is (10%, 36%, 33%) Average monthly increase is 26% How do I get excel to calculate the above? |
