Future Value Calculator
Calculate what a single amount will be worth after compounding at an annual rate for a number of years.
Estimate future value from present value, annual rate, and years.
How to use this calculator
What future value tells you
Future value is what a sum of money will grow to at a given annual rate after a number of years. This calculator compounds a single amount once a year, with no further deposits, so it answers questions like “what will $10,000 be worth in 10 years at 7%?” The answer is about $19,672.
Growth speeds up over time because each year’s gain is calculated on a larger balance. At 7%, $10,000 gains about $9,672 in its first 10 years but about $37,400 in its third decade, growing from $38,697 to $76,123.
Rate and time together
Small differences in rate become large over long periods. After 30 years, $10,000 grows to about $32,434 at 4%, $76,123 at 7%, and $174,494 at 10%. Three extra percentage points more than double the result, which is why fees and rates deserve close attention.
For planning, test a range of rates rather than a single number. Savings accounts and bonds tend to sit at the low end; diversified stock portfolios have historically averaged more, but with losing years along the way.
Adjusting for inflation
Future value is measured in future dollars. If prices rise 3% a year, $19,672 in 10 years will buy roughly what $14,637 buys today. To see growth in today’s purchasing power, subtract expected inflation from your rate and use the result as the rate; it is a close approximation.
This calculator assumes one deposit. If you plan to add money regularly, the compound interest calculator includes monthly contributions.

Formula
- Future value = present value × (1 + r)^n
- r = annual rate as a decimal; n = number of years
Example: $10,000 at 7% for 10 years
- Growth factor: 1.07^10 ≈ 1.9672.
- Future value: $10,000 × 1.9672 = $19,671.51.
- Growth: $9,671.51, almost doubling the original amount.

Frequently asked questions
How much will $10,000 be worth in 20 years?
At 4% a year, about $21,911; at 7%, about $38,697; at 10%, about $67,275. The rate you can realistically earn matters more than anything else.
What is the difference between future value and present value?
They are the same formula run in opposite directions. Future value grows today’s money forward at a rate; present value discounts a future amount back to what it is worth today.
Does compounding frequency matter?
A little. This calculator compounds annually. Monthly compounding at the same stated rate gives a slightly higher result: $10,000 at 7% for 10 years becomes about $20,097 with monthly compounding versus $19,672 with annual compounding.
How do I include regular contributions?
This calculator handles a single amount. Use the compound interest or savings calculator to add monthly deposits.
