About Present Value Calculator
The present value calculator determines how much a future sum of money is worth today by discounting it at a specified rate. This concept is the foundation of all financial valuation: stocks, bonds, real estate, and business projects are all valued by discounting their expected future cash flows to the present. A dollar today is worth more than a dollar tomorrow because today's dollar can be invested to earn a return. The discount rate reflects the opportunity cost of capital, the risk of the future cash flow, and expected inflation. Present value analysis enables you to compare cash flows occurring at different times on an equal footing.
The Math Behind It
Formula Reference
Present Value
PV = FV / (1 + r)^n
Variables: PV = present value; FV = future value; r = discount rate (decimal); n = years
Worked Examples
Example 1: Lump sum pension option
You can receive $50,000 in 10 years. The discount rate is 6%.
The present value is $27,920. You should prefer receiving $27,920+ today over $50,000 in 10 years.
Example 2: Settlement offer
A settlement pays $100,000 in 5 years. Your opportunity cost is 8%.
The present value is $68,058.
Common Mistakes & Tips
- !Using too low a discount rate, which overstates the present value and makes investments seem more attractive.
- !Ignoring risk when choosing the discount rate; riskier cash flows deserve higher discount rates.
- !Forgetting to account for inflation when the future cash flow is in nominal terms.

Frequently Asked Questions
What discount rate should I use?
Use your opportunity cost of capital: the return you could earn on an alternative investment of similar risk. Common choices include the risk-free rate plus a risk premium, the WACC, or a personal required return.
How does inflation affect present value?
Inflation reduces the real value of future cash flows. You can either use nominal cash flows with a nominal discount rate, or real cash flows with a real discount rate. Both approaches yield the same present value.
What is the difference between PV and NPV?
PV is the discounted value of future cash flows. NPV subtracts the initial investment: NPV = PV of inflows - initial cost. A positive NPV means the investment adds value.
