Worked example
Using the 16 percent column, what factor sits at 5 periods, and what is 10,000 times that factor?
- Read down the 16 percent column to row 5, giving 0.145409.
- Multiply: 10000 x 0.145409.
The factor is 0.145409. The product is 1454.09.
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.
