How it works
| Term | Meaning |
|---|---|
| Principal | The starting amount you invest or save. |
| Rate | The annual interest rate in percent. |
| Compounding | How often interest is added to the balance each year. |
| Future value | The estimated balance at the end of the chosen period. |
Formula: A = P × (1 + r/n)n×t, where P is principal, r is the annual rate as a decimal, n is the number of compounding periods per year, and t is time in years.
