Frequently Asked Questions

What is simple interest?

Simple interest = Principal × Rate × Time. Interest is only calculated on the original principal, not on accumulated interest.

What is the difference between simple and compound interest?

Simple interest is calculated only on the principal. Compound interest is calculated on the principal plus accumulated interest, so it grows faster over time.
