Sinking fund at 14 percent

By Jude Wallis

At 14 percent, the sinking fund factor for 5 periods is 0.151284. Multiply a cash amount by that factor. This column is independently recomputed.

The formula

SFF=r(1+r)n1SFF = \frac{r}{(1 + r)^{n} - 1}

Multiply a target future amount by the factor to get the deposit each period.

Worked example

Using the 14 percent column, what factor sits at 5 periods, and what is 10,000 times that factor?

  1. Read down the 14 percent column to row 5, giving 0.151284.
  2. Multiply: 10000 x 0.151284.

The factor is 0.151284. The product is 1512.84.

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.
