How this interest calculator works
This calculator uses simple interest to estimate how much interest builds up over time based on the starting amount, annual rate, and number of years.
Formula
Simple interest = principal × rate × time
Example
If you invest £5,000 at 5% simple annual interest for 3 years, this calculator shows the interest earned and the final total amount.
