When to use this calculator
Use this present value calculator to estimate what a future amount is worth in today's dollars at a chosen discount rate. It is useful for comparing future payments, investment outcomes or long-term savings targets.
Formula
Present value = future value / (1 + discount rate)^years
- Future value is the amount expected later.
- Discount rate reflects the annual return or required rate used for comparison.
- Years is the time until the future amount is received.
Worked example
For $20,000 received 10 years from now at a 5% discount rate, the calculator estimates a present value of about $12,278.
Common mistakes
- Choosing a discount rate without thinking about risk or alternatives.
- Comparing future amounts without adjusting for time.
- Ignoring taxes, fees or uncertainty in the future payment.
FAQs
Why is future money worth less today?
Because money available today could potentially earn a return before the future date.
Is discount rate the same as inflation?
Not necessarily. A discount rate may reflect investment return, inflation, risk or opportunity cost.
Can this compare lump sums?
Yes. It helps compare a future lump sum with a current amount.
