Is there a web site that calculates the return of a mutual fund between any 2 dates supplied?

Answer 1

You might try:
http://finance.yahoo.com/funds/calculator_index

Answer 2

The link supplied won't help you. You need total return points. The only site I know of that provides them up to 5 years back is smartmoney.com

You'll have to get the value points you want, and calculate the return by yourself (although I would submit that the data is meaningless).

If you don't want the distributions included in the return calc, you can use yahoo finance to look up historical prices, but distributions are important to the return (without distributions, even more meaningless).

Good luck
