PROVIDING FOR THE LONG TERM
Supporting Endowments and Investabe Assets
ENDOWMENT  CALCULATOR
Here's a quick way to see how an endowment might perform under different assumptions. Try entering different rates of inflation, assume various rates of return, and reinvest different amounts, to see how these things affect the spendable earnings. Feel free to change your assumptions and recalculate — it's fast and easy. (If you prefer to have the whole Excel spreadsheet, you can download it by clicking here.)
 
Input the amount of the endowment (the whole number amount you intend to invest).
$
What rate of inflation will you assume? The default is 3% which is consistent with historical trends, but raise that number if you prefer to be conservative. Number may include one decimal place.
%
Do you want to reinvest a portion of the earnings? If so, you can reinvest an amount equal to inflation, or you can choose a fixed percentage of the endowment balance.
No, I don't want to reinvest the earnings.
Yes, I want to reinvest an amount equal to inflation.
Yes, I want to reinvest a specific percentage of the principal %
What annual rate of return on your investment do you want to assume? The default is 5% which is a fairly conservative estimate, but feel free to raise or lower that number to see the effect it could have on your endowment.
