## The Formula for Calculating Simple Interest Rate

Calculating simple interest rate is easy. You just have to multiply the principal amount by the interest rate and the time of the loan. The formula for calculating simple interest rate is:

Formula for Simple Interest Rate
Interest = Principal x Rate x Time

👉 Example: If you borrowed \$10,000, with an interest rate of 5% for five years. The calculation will be:

Calculation for Simple Interest Rate
Interest = \$10,000 x 5% x 5
Interest = \$2,500

## The Formula for Calculating Compounded Interest Rate

Compounded interest rate is a little bit more complicated. It involves calculating the interest that has accumulated on top of the borrowed principal amount. It is also called the future value of the loan. The formula for calculating compounded interest rate is:

Formula for Compounded Interest Rate
Future Value = Principal x (1 + Rate)^Time

👉 Example: If you borrowed \$10,000, with a compounded interest rate of 5% for five years. The calculation will be:

Calculation for Compounded Interest Rate
Future Value = \$10,000 x (1 + 5%)^5
Future Value = \$12,763.25
