Present Value Calculator
Find what a future amount is worth today.

How it is calculated
Present value discounts a future amount back to today: PV = FV / (1 + r)t. FV is the amount you will receive, r is the discount rate per period (you type the percent and the tool divides by 100) and t is the number of periods. The tool labels t as years and accepts fractions, but the rate and the period must match: use an annual rate with years, or a monthly rate with a number of months. Negative time returns no result. A higher discount rate or a longer wait lowers the present value. This handles one lump sum only; a series of payments has to be discounted one by one and added up.
Worked example
You will receive 10,000 in 10 years and use a 5% discount rate. Growth factor: 1.0510 ≈ 1.628895. Present value = 10,000 / 1.628895 ≈ $6,139.13. In other words, 6,139.13 today at 5% a year grows to 10,000 after 10 years.
Common mistakes
- Entering the rate as 0.05 instead of 5.
- Mixing periods, such as an annual rate with a number of months.
- Choosing a discount rate without thinking about risk and inflation, which changes the answer a lot.
- Using this for several payments at once; each payment needs its own discounting.
- Confusing present value with future value: this tool goes from the future amount back to today.
About this calculator
This calculator applies the core time-value-of-money formula, PV = FV / (1 + r)ⁿ, to discount a future sum of money back to what it's worth today, given a discount rate (r) and number of periods (n) — the same principle behind the idea that a dollar today is worth more than a dollar in the future.
Finance students and analysts use it to value bonds, evaluate investment opportunities, and compare offers like a lump-sum settlement versus a future payout, while businesses use it in capital budgeting to decide whether a future cash flow justifies an investment made today. The result is highly sensitive to the chosen discount rate, so the calculator makes it easy to see how a small change in rate assumptions swings the present value.
