FAQ
What is compound interest?
Compound interest means you earn interest on your previous interest, not just the principal. Over time this creates exponential growth - the magic of compounding.
How often should I compound?
More frequent compounding equals more growth. Options: Annually (1x/year), Quarterly (4x), Monthly (12x), Daily (365x). Monthly is common for savings accounts.
What if I add monthly contributions?
Enter your regular contribution amount. The calculator adds it each period before compounding, dramatically increasing long-term growth.
