Future Value Calculator
Calculate the future value of a lump sum investment with compound interest. See how your money grows over time with different compounding frequencies.
The Future Value Calculator projects what a lump-sum investment grows to under compound interest, using the standard formula FV = PV x (1 + r/n)^(n x t), where you control the Present Value, annual interest Rate, Time Period in years, and Compounding Frequency. Present Value sets the scale for everything else this calculator reports, since the entire future balance is a direct multiple of it — the compounding factor scales your principal up, but the principal itself sets the base every other output is proportional to. Compounding Frequency changes the results in a specific, verifiable way even when the stated annual rate stays fixed: because the Effective Annual Rate (APY) output is derived from (1 + r/n)^n - 1, more frequent compounding (daily versus annual, for instance) produces a slightly higher effective yield for the identical nominal rate, since interest starts earning its own interest sooner and more often within the year. This calculator assumes a single fixed rate and no additional contributions after the initial Present Value — it has no input for ongoing deposits, so it's built specifically for lump-sum growth projections rather than a savings plan with regular contributions, and it does not account for taxes, fees, or inflation eroding the purchasing power of the future balance.

How to Use This Calculator
- Enter the present value (principal) — the amount you are investing or saving today.
- Set the annual interest rate for your investment or savings account.
- Enter the number of years you will hold the investment.
- Select compounding frequency — more frequent compounding (daily or monthly) yields slightly more than annual.
- Review the future value, total interest earned, and effective annual rate (APY).

Frequently Asked Questions
What is future value?
Future value is what a sum of money invested today grows to after a set period, given a specific rate of return and compounding schedule. This calculator applies the standard compound interest formula, FV = PV x (1 + r/n)^(n x t), to your Present Value, Annual Interest Rate, Time Period, and Compounding Frequency to project that ending balance.
How does compounding frequency change my future value?
More frequent compounding lets interest start earning its own interest sooner within each year, so for the identical stated Annual Interest Rate, switching from annual to monthly or daily compounding raises the Effective Annual Rate (APY) output slightly and, over time, produces a modestly higher Future Value. The difference is usually small for short time periods but becomes more noticeable the longer your Time Period runs.
Does this calculator account for additional contributions over time?
No — this calculator projects growth from a single Present Value entered once, with no input for ongoing monthly or annual deposits, so it models pure lump-sum compounding rather than a regular savings plan. If you're contributing money periodically in addition to an initial deposit, this tool will understate your true ending balance.
What does the Growth Multiple output tell me?
Growth Multiple is Future Value divided by Present Value — how many times over your money has grown, independent of how much you started with. It is a quick way to compare scenarios: a 2.0x multiple means your balance doubled over the Time Period you entered, whichever Present Value you began from, and it lets you sanity-check a projection against rules of thumb like the Rule of 72.
