Compound interest is interest on investments. Importantly, it compounds, which means that your interest earns interest.
The formula for compound interest is A = P(1+(r/n))^(n*t). A is the future value. P is the starting amount. r is annual interest rate. n is compounding rate per year. t is number of years in market.

On a simple level, the future balance is discounted by cumulative inflation to express it in today's dollars.
