What is Simple Interest?

Back

Simple Interest is the interest calculated on the principal amount only, without compounding. It can be calculated using the formula: Simple Interest = Principal × Rate × Time.

What is the formula for calculating Simple Interest?

Back

The formula for calculating Simple Interest is: SI = P × R × T, where SI is Simple Interest, P is Principal, R is Rate (in decimal), and T is Time (in years).

How do you convert an interest rate from a percentage to a decimal?

Back

To convert a percentage to a decimal, divide the percentage by 100. For example, 7% becomes 0.07.

What happens to Simple Interest if the principal amount increases?

Back

If the principal amount increases, the Simple Interest will also increase, assuming the rate and time remain constant.
