Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on the initial principal and accumulated interest from previous periods. It allows your money to grow exponentially over time.
How does compound frequency affect growth?
The more frequently interest is compounded, the faster your money grows. Daily compounding will yield more than annual compounding at the same rate.
What's the difference between simple and compound interest?
Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus accumulated interest, leading to exponential growth.
How can I maximize compound interest?
Start early, invest regularly, choose higher interest rates when possible, and let your money compound over long periods without withdrawing.
Is compound interest always beneficial?
Compound interest benefits savers and investors, but it works against borrowers. Credit card debt and loans use compound interest, making them expensive over time.
