Interactive Concept: Solve for the Number of Years

An interactive time value of money model for students to enter present value, future value, and annual interest rate, then see the implied number of years needed to reach the target.

Prototype
Implied Number of Years
20.0 years
Annual Interest Rate
10.0%
$10,000 grows to $67,275 at 10.0% annual interest.
