Anyone can be a millionaire if they start investing today. Compound Interest Calc uses a predictive formula to compute the future value of your money.

Imagine you start with a $1000 investment and contribute $400/month at 10% interest annually (same average interest rate as S&P 500/Composite index since 1926). After 40 years you will have $2.58 MILLION. 10 more years and you've earned $7.08 MILLION! This is the power of compound interest.

Features included:
