Dave's Compound Interest Calculator

Watch the your money grow over time.

This application calculates basic compound interest over a specified number of years. Typically you would use this to figure out the value of an investment (stock, mutual fund, bond, CD, bank account, etc.). But it can also be used to plan out a retirement strategy, see the value of your money affected by estimated inflation, or see how contributions will add up over time.

Server-Side Version

This is my newest Javascript version of the calculator. Long ago, the calculator used to be server-side (PHP). For a while, I maintained both versions, but I've recently discontinued. If there is any interest in having the server-side version again, let me know and I'll be happy to accomodate. Thanks!
