Frequently Asked Questions
Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest. With compound interest, you earn interest on your interest, leading to exponential growth over time.
More frequent compounding results in higher returns because interest is calculated and added to your principal more often. For example, $10,000 at 5% for 10 years: annually compounded = $16,288.95, monthly compounded = $16,470.09, daily compounded = $16,486.65.
Generally, a higher interest rate has a much larger impact than more frequent compounding. Focus on finding the best interest rate first, then consider compounding frequency.
Regular contributions significantly boost your returns because each contribution also earns compound interest. For example, investing $1,000 initially and adding $100/month for 30 years at 6% yields $100,451.50.
Compound interest works in your favor when you're saving or investing, but it works against you when you have debt. Credit cards and loans use compound interest, meaning you pay interest on interest.
