About Compound Interest Calculator — Free Online Calculator
Compound Interest Calculator grows a starting amount, plus a recurring monthly deposit if you add one, and separates the final balance into what you contributed and what the interest built.
One detail is worth knowing before you read the result: the compounding frequency you pick, anywhere from 1 to 365 times a year, applies to the opening lump sum only. Monthly deposits are always compounded monthly, as an ordinary annuity credited at the end of each month, so choosing annual compounding will not slow the deposits down to match. Nothing is deducted for tax, inflation or account charges, so the closing balance is a gross figure.
Starting amount, deposit and rate stay on your device; nothing is logged and nothing is posted to a server.
Projecting a recurring deposit over a fixed term, separating contributions from growth in a savings plan, testing what one extra percentage point does across twenty years, and checking a maturity figure a provider has quoted.
