Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It causes investments to grow faster than simple interest.
How is compound interest different from simple interest?
Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any previously earned interest.
What does compounding frequency mean?
Compounding frequency determines how often interest is calculated and added to the balance. More frequent compounding (e.g., monthly vs yearly) results in higher returns.
How do I calculate compound interest manually?
The formula is A = P(1 + r/n)^(nt), where P is principal, r is annual rate, n is compounding frequency, and t is time in years.
