Present Value Calculator

What a future amount or payment stream is worth today.

If the present value above exceeds this, the future money is worth more than the cash offer.

How sensitive is this to the rate?

The discount rate is the judgment call, and small differences move long-dated values a lot.

About the Present Value Calculator

Enter a future amount, a discount rate and the number of periods to get the present value: what that money is worth today. The calculator handles a single future sum, a stream of equal payments, or both together.

Present value is the tool for any decision involving money at different times. Comparing a lump sum offer against instalments, valuing a pension against its cash alternative, judging whether a settlement is fair, deciding if a lease is better than a purchase: all of them reduce to discounting future amounts back to today at an appropriate rate. That rate is the judgment call, since it represents what you could otherwise earn, and small differences in it change long-dated values considerably.

Key features of the Present Value Calculator

Lump sum and annuity together

A future amount, a recurring payment, or an arrangement containing both.

The lump-sum decision

Compare a cash offer against the present value of the payments it replaces, which is the only fair test.

Rate sensitivity

Small changes in the discount rate move long-dated values a lot, and the calculator makes that visible.

Begin and end timing

Payments at the start or end of each period, which changes the value by one period of interest.

Any compounding frequency

Annual through daily, matched to how the arrangement actually pays.

What a future amount of money is worth today, given that money available now could be invested and grow. It is the reverse of compounding: instead of growing a sum forward, you discount it back.
