Present Value Calculator
Calculate the present value of a future lump sum or a series of equal cash flows using a discount rate and time period.
Overview
A present value calculator helps you estimate what future money is worth today. Enter a future amount or recurring payment, your discount rate, the number of years, and payment frequency to see the current value in today's terms.
How it works
Present value discounts future money back to today using a chosen rate of return or discount rate. For a lump sum, the calculator divides the future amount by one plus the periodic rate raised to the number of periods. For recurring equal payments, it uses the standard present value of an annuity formula. A higher discount rate or longer time period generally reduces present value.
How to use this calculator
- 1Choose whether you want to value a future lump sum or recurring payments.
- 2Enter the future value or payment amount.
- 3Add the annual discount rate you want to use.
- 4Enter the number of years and select the payment frequency.
- 5Review the estimated present value and discount amount.
Example Calculation

Discount rate

Payments per year

Present value
$7,413.72
If you expect to receive 10,000 in 5 years and use a 6% annual discount rate with monthly periods, the present value is about 7,414. This means 10,000 in the future is worth roughly 7,414 today at that discount rate.
Frequently asked questions
What does this present value calculator estimate?
It estimates what a future lump sum or a series of equal payments is worth today using your chosen discount rate and time period.
What discount rate should I use?
Many people use an expected return rate, required rate of return, borrowing cost, or opportunity cost. The right rate depends on your purpose and assumptions.
What is the difference between present value and future value?
Future value shows what money may be worth later after growth, while present value shows what that future amount is worth today after discounting.
Does this calculator include inflation?
Not automatically. If you want to reflect inflation or risk, you can build that into the discount rate you enter.
How are recurring payments treated?
The calculator assumes equal payments made at the end of each period, such as monthly or annual payments, over the chosen time span.
Why does a higher discount rate lower present value?
A higher rate increases the reduction applied to future cash flows, so the amount they are worth today becomes smaller.

Assumptions and warnings
Assumptions
- The discount rate stays constant for the full calculation period.
- Recurring payments are assumed to be equal and made at the end of each period.
- The result is an estimate and does not include taxes, fees, inflation adjustments, or investment risk unless you reflect them in the discount rate.
- The calculator uses the selected payment frequency to convert the annual rate into periodic discounting.
Warnings
- This calculator provides an estimate only and is not financial advice.
- Use care when comparing results, as small changes in discount rate or timing can materially change present value.
