Question 1

What is simple interest?

Accepted Answer

Simple interest is interest calculated only on the original principal amount. Unlike compound interest, it does not account for accumulated interest from previous periods. The formula is SI = P x R x T, where P is principal, R is annual rate, and T is time in years.

Question 2

What is the difference between simple and compound interest?

Accepted Answer

Simple interest is calculated only on the initial principal, growing linearly over time. Compound interest is calculated on the principal plus accumulated interest, growing exponentially. Over long periods, compound interest generates significantly more returns.

Question 3

Where is simple interest commonly used?

Accepted Answer

Simple interest is commonly used in short-term loans, car loans, some personal loans, and certain fixed-term deposits. It is easier to calculate and results in lower interest charges compared to compound interest for the same rate and period.
