Simple interest calculator
Work out simple interest on an amount, with no compounding.
About this calculator
Simple interest is calculated only on the original amount: amount × rate × years. Unlike compound interest, it does not grow on itself. It is used for some short loans and bonds.
Enter the amount, the yearly rate and the number of years to see the interest and the total.
Common questions
What is the formula?
Interest = amount × yearly rate ÷ 100 × years.
How is it different from compound interest?
Compound interest is also earned on past interest, so it grows faster over long periods.
