What is compound interest?
Compound interest means that the interest you earn in one period is added to your principal, so in the next period you earn interest on a larger base. This creates exponential growth: the longer your time horizon, the more dramatic the effect.
Which rate should I use?
The S&P 500 has historically returned ~10%/year before inflation over long periods - use this for an all-equity US index fund scenario. A balanced growth portfolio (stocks + bonds) is closer to 7%. High-yield savings accounts (HYSA) are currently paying around 4-5% with FDIC insurance and zero market risk. Bonds historically return ~4% annualized.
Formula used
FV = PV × (1+r)^n + PMT × ((1+r)^n − 1) / rwhere r is the monthly rate, n is the number of months, PV is the initial investment, and PMT is the monthly contribution. Annual rates are converted to monthly viar = (1 + annual%)^(1/12) − 1.
