I want to find a calculator where between any two dates provided, the return on a given amount of money is calculated for the actual returns of the S&P 500 between those dates.


MoneyChimp is great for this. It only offers full year returns, but it compounds the results correctly, including dividends. For mid year results, just adjust a bit based on the data you can find from Google or Yahoo to add some return (or loss) for the months.

Well i dont know of any calculator but you can do the following

1) Google S&P 500 chart

2) Find out whats the S&P index points (P1) on the first date

3) Find out whats the S&P index points (P2) on the second date

4) P1 - P2 = result

   returns in % = result / P1 * 100

    Welcome to Money.SE. Nice try, unfortunately, the S&P index does not reflect dividends. So Jan, 1980 at 114.16 to Dec 2013, 1848.36, looks like only a 1519% return, pretty awful compared to actual return of 4355% when you include dividends. – JTP - Apologise to Monica Jan 24 '14 at 19:06
