Investment Summary
Future Value Formula
FV = PV(1+r)^n + PMT × [((1+r)^n - 1) / r]
Where PV = present value, PMT = periodic payment, r = periodic rate, n = periods
About the Future Value Calculator
The Future Value Calculator projects what a sum of money will be worth at a future date once interest or investment returns are applied. For a single lump sum it uses FV = PV(1 + r)^n, where PV is the present value, r is the periodic rate, and n is the number of periods. When you add regular contributions, it layers on the future value of an annuity formula so the tool can model both an initial deposit and ongoing monthly or annual savings.
This is the core building block of financial planning because it answers how money grows over time when left to compound. Entering a starting balance, an expected rate of return, a contribution amount, and a time horizon reveals not just the final figure but how much of it came from your own deposits versus earned growth. That split is illuminating, since over long horizons the growth component often dwarfs the contributions.
Use the Future Value Calculator to project retirement accounts, college funds, or any goal-based investment, and pair it with the Savings Goal Calculator when you instead know the target and need to solve for the required deposit. The CAGR Calculator runs the same compounding math backward to measure historical growth, while the APY Calculator handles the effective-yield side of bank products. Together they cover both the planning and the measuring of compound growth.
A practical tip is to test a range of return assumptions rather than a single optimistic one. Markets are uneven, so modeling a conservative, moderate, and aggressive rate gives you a realistic spread of outcomes. Also remember that future value figures are in nominal dollars; inflation will erode purchasing power, so consider discounting your target or using a real rate of return for long horizons.
Frequently asked questions
- What is the future value formula for a lump sum?
- FV = PV(1 + r)^n, where PV is the present value, r is the rate per period, and n is the number of periods.
- How does adding monthly contributions change the result?
- Each contribution earns compound growth for the remaining time until the end date, so regular deposits can dramatically increase the final value beyond the initial lump sum alone.
- Does future value account for inflation?
- No, it shows nominal dollars by default. To estimate real purchasing power, use an inflation-adjusted (real) rate of return or discount the result for inflation.
- What rate of return should I assume?
- It depends on the asset. Many planners use 4-7% for diversified stock portfolios after inflation, but testing multiple rates gives a more realistic range of outcomes.
