Future value answers a simple question: if you invest a lump sum today, how much will it grow to by a specific date, given a fixed rate of return?

This calculator finds the future value of a single lump-sum investment, accounting for your chosen compounding frequency, with a full step-by-step solution.

How it works

Enter the present value (the lump sum today), the annual interest rate, the number of years, and how often interest compounds. The calculator applies the compound interest future value formula to project the investment forward.

  1. Enter present value ($).
  2. Enter annual interest rate (%).
  3. Enter years.
  4. Enter compounding frequency.
  5. Click Calculate to see your results.

Examples

$10,000 growing at 6% for 10 years

A $10,000 lump sum invested at a 6% annual rate, compounded annually, grows to about $17,908.48 after 10 years.

Who should use it

  • Projecting how much a one-time investment will be worth at a future date.
  • Comparing the impact of different compounding frequencies on the same rate.

Industry applications

  • Personal finance and investment planning
  • Banking and financial product illustration

Advantages

  • Supports five common compounding frequencies (annually through daily).
  • Includes a complete, formula-based step-by-step solution.

Limitations

  • Only models a single lump sum — use a dedicated calculator with regular contributions for ongoing savings plans.

Common mistakes to avoid

  • Entering a monthly rate instead of the annual rate — this calculator expects the annual rate and divides it internally based on your chosen compounding frequency.
  • Ignoring the impact of compounding frequency — the same stated annual rate produces different results depending on how often it compounds.

Best practices

  • Match the compounding frequency to your actual investment or account terms for an accurate projection.

Tips

  • If you also make regular ongoing contributions (not just a one-time lump sum), use a savings or retirement calculator designed for periodic contributions instead — this tool only models the single upfront amount.

Frequently asked questions

Yes, with no signup and no limit on how many calculations you run.
This calculator is a simpler, single-lump-sum version — it doesn't model ongoing contributions, unlike calculators built specifically for regular deposits.
Use whatever frequency matches your actual account or investment — more frequent compounding (like daily or monthly) produces a slightly higher future value than less frequent compounding (like annually) for the same stated rate.
No — this calculates gross investment growth only; taxes, account fees, or inflation are not factored in.
