Frequently asked questions
What is compound interest?
Compound interest is interest earned not only on your initial amount but also on the interest already accumulated. That is why savings grow faster over time ("interest on interest").
How do monthly deposits help?
Regular deposits substantially increase the future value, especially over long periods, because each deposit also starts earning interest.
What compounding does it use?
This calculator uses monthly compounding with deposits added at the end of each month — a common model for savings accounts.
