Present Value (PV) Calculator
Determine what a guaranteed future sum of money is worth in today’s dollars. This calculator applies the classic discounting formula to translate future nominal cash flows into present purchasing value based on your cost of capital.
Lump-sum dollar amount to be received in the future
Annual interest rate, inflation rate, or required hurdle rate
Number of years until the future cash flow is realized
What the future money is worth today in current purchasing power
How to Use This Calculator
- Enter the promised future cash amount you expect to receive.
- Enter your annual discount rate or expected rate of return.
- Enter the number of years until you receive the future sum.
- Review the Present Value to determine whether an upfront payout is fair value.
Formula & Calculation Methodology
Present Value discounts expected future receipts by dividing by compounded interest factors, reflecting the opportunity cost of waiting.
Worked Example
$50,000 to be received in 5 years discounted at 8% annual hurdle rate
Frequently Asked Questions
Why does money lose value over time in Present Value calculations?↓
Two core reasons: opportunity cost (money today can be invested to earn compound returns) and purchasing power erosion (inflation makes future dollars buy fewer real goods).
How do I choose the correct discount rate?↓
For risk-free government securities, use current Treasury yields. For personal investments, use your expected equity portfolio return. For corporate projects, use the Weighted Average Cost of Capital (WACC).
Can this tool be used to evaluate lottery lump-sum vs. annuity payouts?↓
Yes. By discounting future annuity distributions at prevailing interest rates, you can objectively determine whether the upfront cash lump sum offers higher net economic value.
What happens to Present Value when the discount rate increases?↓
As the discount rate increases, Present Value decreases. Higher alternative investment yields make future cash receipts comparatively less valuable in today’s terms.
