Question 1

What is simple interest?

Accepted Answer

Simple interest is interest calculated only on the original principal amount, not on any interest already earned. It stays the same every year for a fixed principal and rate.

Question 2

What is the simple interest formula?

Accepted Answer

Simple Interest = (Principal x Rate x Time) / 100. The total amount you receive is Principal + Simple Interest.

Question 3

What is the difference between simple and compound interest?

Accepted Answer

Simple interest is charged only on the principal. Compound interest is charged on the principal plus accumulated interest, so it grows faster over time. Most bank deposits and loans use compound interest.

Question 4

Where is simple interest used?

Accepted Answer

Simple interest is used in some short-term loans, certain car loans quoted on a flat basis, and informal lending. Always check whether a rate is simple or compound before borrowing or investing.
