Frequently Asked Questions

What is compound interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods.
How does compounding frequency affect returns?
More frequent compounding (e.g. monthly vs annually) produces slightly higher returns because interest is reinvested sooner.
Is this a savings or investment calculator?
It works for any scenario where returns compound: savings accounts, investments, or loans.
Are my inputs saved?
No. The calculator runs entirely in your browser. Nothing is sent to a server.
