I have the following simple function that I need to call n times and sum the result.
I wish to call this 30 times, with n being 1-30, then sum the result. How can I do this in Excel?
You can use the following array formula.
Paste the formula into the formula bar and press Ctrl+Shift+Enter. It doesn’t matter where you enter the formula or what the contents of
A1:A30 are; the
A1:A30 is just a trick to get Excel to iterate through the formula 30 times.
I know it’s been a few years, but I just stumbled across this today, 5-29-17. Here is the correct formula: sum=10000((1-1.01^31)/(1-1.01)-1)=351327. I verified this result with brute force in Excel. James Kane
P.S.: I tried to comment on the above two answers, but it would not let me because I am new here. The issue with the first answer is a typo (should be 10,000 not 1,000). The second answer also has a typo (should be 10,000 not 100,000) and an incorrect formula.
