Present value calculator
Discount a future lump sum back to today with a per-period rate and number of periods.
What this calculator covers
Use this calculator to estimate what a future lump sum is worth in today's dollars at a chosen per-period discount rate.
It is useful for comparing delayed cash flows, target balances, and bond-style maturity values on a common present-value basis.
Frequently asked questions
- What does present value mean?
- Present value is today's equivalent of a sum of money you expect to receive in the future. Because money available now can be invested and earn returns, a future dollar is worth less than a dollar today — present value quantifies exactly how much less, given a chosen discount rate and time horizon.
- What should I use as the discount rate?
- The appropriate rate depends on context. Common choices include a savings or investment return rate you could otherwise earn, a cost of capital for a business decision, or an inflation rate for real purchasing-power comparisons. The rate and the number of periods must use the same time unit.
- How is this different from a present value annuity calculator?
- This calculator handles a single future lump sum. A present value annuity calculator handles a series of equal recurring payments. If you are evaluating one future cash event, use this tool; if you are evaluating a stream of periodic payments, use the annuity version.
- Does a higher discount rate always lower the present value?
- Yes. A higher discount rate means you require more return to justify waiting, so the present value of any fixed future amount shrinks. Similarly, a longer time horizon also lowers the present value because the future amount is discounted across more periods.

$8,356.45
$10,000.00 received in 36 periods is worth $8,356.45 today when discounted at 0.50% per period.
- Present value
- $8,356.45
- Discount factor
- 0.83564492
- Discount amount
- $1,643.55
Step-by-step solution
- 1.Build the discount factor from 36 periods at 0.50% per period.
- 2.Multiply the future cash amount by the discount factor of 0.83564492.
- 3.The gap between future dollars and present value is the $1,643.55 discount amount.
Walkthrough
Visual walkthrough
Present value turns one future dollar amount into today’s equivalent by discounting it across the required number of periods.
01
Start with the future lump sum
$10,000.00
The future value is the amount you expect to receive at the end of the timeline.
02
Discount across the horizon
(1 + 0.50%)^-36
The discount factor shrinks the future amount based on both the rate and the number of periods.
03
Read today’s equivalent
A higher discount rate or longer timeline lowers the present value because more return is required to justify waiting.
