Frequently Asked Questions
Compound interest is interest calculated on both the principal and the accumulated interest. Money grows faster than simple interest.
Simple interest is calculated only on principal. Compound interest is calculated on principal plus accumulated interest, leading to exponential growth.
More frequent compounding = more growth. Monthly compounding earns more than annual compounding at the same rate.
