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.
