Input your monthly contribution amount.

The calculator shows future value, total contributions, and investment gains.
Formula Explanation
Future Value = P(1+r)^n + PMT × [((1+r)^n - 1) / r]Where P is the initial investment, PMT is the monthly contribution, r is the monthly return rate (annual return ÷ 12), and n is the number of months. This calculates compound growth with regular contributions.
Tips
Historical stock market returns average 7-10% annually, but past performance doesn't guarantee future results.
Diversify your investments to manage risk.
Start investing early to maximize compound growth.
Regular contributions (dollar-cost averaging) can reduce risk.
Consider fees and taxes when calculating actual returns.
