You can solve for any constant in the compound interest formula

In an earlier FAQ, we looked at solving for the rate *r*. In the FAQ below, we look at how logarithms can be used to solve for the number of years, *n*, in the power.

The compound interest formula has several constants in it. If you are given all but one of these constants, you can solve for the remaining constant.

In this FAQ, we look at solving for the rate *r* using roots.
