Questions & Answers

Q: What is the difference between simple interest and compound interest?

Simple interest only calculates interest on the principal amount, while compound interest includes interest on the interest from previous years.

Q: Why does compound interest result in a higher amount than simple interest?

Compound interest accumulates over time, including interest on the interest earned in previous years, resulting in a higher overall amount.

Q: How does the interest rate affect the difference between simple and compound interest?
