How It Works
The calculator uses the simple interest formula:
Simple Interest = (Principal × Rate × Time) ÷ 100
Where:
- Principal is the amount of money you start with.
- Rate is the annual interest rate in percent.
- Time is how long the money is invested or borrowed, in years.
Simple interest means the interest is only calculated on the original amount — it doesn’t compound or build on itself.
Example
If you invest KES 10,000 at an annual interest rate of 5% for 2 years,
Simple Interest = (10,000 × 5 × 2) ÷ 100 = KES 1,000
Your total amount after 2 years will be:
10,000 + 1,000 = KES 11,000
