Compound interest calculator
See how an initial amount and monthly contributions grow with compound interest over the years.
With compound interest the returns of each year also earn returns in the following years, so growth accelerates over time. The calculation assumes the same return every year, which never happens with real investments.
Educational tool. Results are approximate, before taxes and fees, and are not investment advice.
