What Is a Future Value of Investment Calculator?
The Future Value of Investment Calculator estimates the growth of your investments over time using compounding and regular contributions. It takes into account:
- Initial Investment – The starting principal amount
- Periodic Contributions – Monthly or yearly additions to the investment
- Annual Interest Rate – Expected return on investment
- Compounding Frequency – How often interest is applied (monthly, quarterly, annually)
- Time Horizon – Number of years for the investment
The result is the future value, showing how much your investment will be worth at the end of the period.
Why Use a Future Value of Investment Calculator

- Provides accurate estimates of investment growth

How the Future Value of Investment Calculator Works
The calculator uses the standard future value formula:
FV = P × (1 + r/n)^(n × t) + PMT × [((1 + r/n)^(n × t) − 1) / (r/n)]
Where:
- FV = Future Value of investment
- P = Initial investment (principal)
- r = Annual interest rate (decimal)
- n = Number of compounding periods per year
- t = Number of years
- PMT = Regular contribution per period
This formula accounts for both growth of the principal and contributions, factoring in compounding.
