Present value table (PV factor)

A present value factor is what 1 unit received n periods from now is worth today. It is 1 divided by (1 + r) to the power n. At 8 percent for 5 periods the factor is 0.6806, so 1,000 due in 5 years is worth 680.60 today.

The formula

PV factor=1(1+r)nPV\text{ factor} = \frac{1}{(1 + r)^{n}}

Multiply a single future amount by the factor to bring it back to today.

Present value of 1, periods down the side and interest rates across the top.

Worked example

What is 1,000 due in 5 years worth today at 8 percent?

  1. Read down the 8 percent column to row 5, giving 0.6806.
  2. Multiply the amount by the factor: 1000 x 0.6806.

680.60 today.

How these figures were checked

Every factor on this page is recomputed before the site can build, by a separate program that works a different way: repeated multiplication instead of a power function, a period-by-period sum instead of a closed-form annuity factor, and a solved loan schedule instead of a payment formula. If the two methods disagree anywhere, the page does not ship. Printed factor tables carry typos because nobody can check three thousand numbers by hand; this one is checked on every build.

This page is educational material, not financial advice. The figures come from the formula shown and assume the inputs you enter hold for the whole term. Your own rate, fees, taxes and timing will differ, so treat the output as arithmetic to check a decision against, not as a recommendation.
