Lump Sum Future Value Calculator
Use this calculator to determine the future value of a lump sum.
How the lump sum future value calculator works
It compounds a single investment forward — with no further contributions — at your rate and compounding frequency, showing how much growth turns the principal into its future value.
Worked example: with investment amount of $25,000, annual return of 7.00% and years invested of 20, the lump sum future value calculator shows value in 20 years of $100,968.
- Initial investment
- $25,000

The formula
Future value = amount × (1 + rate ÷ n)^(n × years), where n is the number of compounding periods per year.

Questions about the lump sum future value calculator
What is the future value of a lump sum?
What a single amount invested today grows to by a future date at a given rate, assuming you add nothing more and let it compound.
How much does compounding frequency change the result?
Modestly. More frequent compounding (monthly or daily versus annual) earns a little more on the same nominal rate, as the calculator shows.
Is this adjusted for inflation?
No — it shows nominal future dollars. Subtract expected inflation from your rate to estimate real buying power.
Is the Lump Sum Future Value Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
