This calculator shows how an investment grows over time with compound interest — the effect of earning returns on both your original money and the returns it has already generated.
Enter your starting amount, a monthly contribution, an expected annual return, and a time horizon to see your projected balance, how much of it is contributions versus growth, and — if you turn on the inflation toggle — what the result is worth in today's money.
