Future Value Calculator

Future value (FV) tells you what a sum of money invested today will be worth at a specified point in the future, assuming a given rate of return. It's one of the most powerful concepts in personal finance because it shows the concrete impact of starting to invest early. Even modest monthly contributions, when compounded over decades, can produce a dramatically larger outcome than most people expect.

This calculator uses monthly compounding throughout. The formula accounts for both your initial lump sum and any regular monthly contributions, growing both at the same annual interest rate. The result is a complete picture of potential wealth accumulation. If you want to reverse the question — finding how much a future sum is worth in today's dollars — use the Present Value Calculator.

Future value projections are foundational for retirement planning and long-term investment strategies. By adjusting the rate and contribution amount, you can quickly see how different market returns or savings habits affect your outcome.
