WHAT IS DOLLAR-COST AVERAGING? Dollar-cost averaging (DCA) means investing a fixed amount at regular intervals, regardless of price. It removes the need to time the market and turns investing into a steady, repeatable habit.

WHO IT'S FOR • Investors planning funds, index portfolios, or long-term savings • Anyone saving toward retirement, a home, or a child's education • Anyone who wants to see compound interest and DCA at work

ABOUT THE MODEL To keep results clear, returns are assumed to be smooth and constant, and taxes and fees are not included. Withdrawals are taken each period before growth, and the balance never falls below zero. Results are for learning and illustration only and are not financial advice.
