Dollar cost averaging (DCA) in MASI means investing a fixed amount at regular intervals, regardless of share price. This strategy reduces timing risk and builds wealth steadily through market ups and downs.
How This Calculator Works
Our DCA calculator simulates real market conditions using historical price data. It accounts for dividend reinvestment (DRIP), where each dividend payment automatically purchases additional shares. You can adjust the investment amount, frequency, time period, and compare against benchmarks like the S&P 500 and Nasdaq-100.
Same amount invested each month — only the day of purchase changes. How much does intra-month timing actually matter?
