Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. It makes your money grow faster than simple interest.
How does compounding frequency affect returns?
More frequent compounding (monthly vs annually) results in slightly higher returns because interest is calculated and added to the principal more often.
