Recurring investment
Model monthly contributions with an assumed annual return.
A hypothetical monthly projection, not a historical backtest or a forecast. Contributions occur at each month-end. The annual return is effective, converted into a constant monthly rate. Negative returns are supported; taxes and trading costs are excluded.
Method: Investor.gov compound interest calculator. For actual price-based purchases, select Historical DCA backtest.
