Frequently Asked Questions

What is compound interest?+
Compound interest is interest calculated on both the initial principal and accumulated interest. Unlike simple interest, your earnings generate their own earnings, producing exponential growth over time.
How does compounding frequency affect returns?+
More frequent compounding (daily vs. annual) produces slightly higher returns because interest starts earning interest sooner. The difference is most noticeable with high rates and long time periods.
What is the Rule of 72?+
The Rule of 72 estimates how long it takes to double your money: divide 72 by the annual interest rate. At a 7% annual return, your money doubles roughly every 10.3 years (72 / 7 = 10.3).
Are the results guaranteed?+
No. This calculator assumes a fixed rate, which suits savings accounts and bonds. Investment returns (stocks, funds) vary year to year. Use average historical returns for long-term projections.
