Dollar-Cost Averaging

Dollar-cost averaging is the practice of investing a fixed dollar amount at regular intervals — monthly, quarterly — regardless of whether the market is up or down.

In more depth

Dollar-cost averaging removes market timing from the equation. By investing consistently, you automatically buy more shares when prices are low and fewer shares when prices are high, which can reduce your average cost per share over time.

How DCA works in practice

You commit to investing $500 on the first of every month into SCHD, regardless of price.

| Month | SCHD price | Shares purchased | |---|---|---| | January | $80 | 6.25 | | February | $72 | 6.94 | | March | $68 | 7.35 | | April | $76 | 6.58 |

After four months: invested $2,000, own 27.12 shares, average cost per share = $73.75.

If you had invested the full $2,000 in January at $80, you'd own 25 shares with an average cost of $80. DCA bought more shares at a lower average cost — simply by being systematic during a period of price decline.

Why DCA matters for dividend investors

Most dividend investors build their portfolios gradually through regular contributions — monthly contributions from a paycheck, reinvested dividends, or periodic transfers. This is DCA by nature.

The behavioral advantage is important: DCA removes the psychological pressure of trying to find the "right" time to invest. You don't need to decide whether now is a good time to buy. You simply execute your plan and let the market do what it does.

DCA vs lump sum investing

Research consistently shows that lump sum investing — putting all available capital to work immediately — outperforms DCA roughly two-thirds of the time over long periods. This makes mathematical sense: markets tend to go up over time, so money invested sooner has more time to compound.

But DCA has a real behavioral advantage: it prevents investors from delaying investment indefinitely while waiting for a "better" entry. An investor who sits on cash waiting for the "right" moment often waits too long and misses returns. A DCA investor is always invested and always building.

DCA and the dividend snowball

When combined with DRIP, dollar-cost averaging creates a powerful compounding engine. Regular contributions buy new shares, which generate dividends, which buy more shares through DRIP, while monthly contributions continue adding new shares at whatever the current price is.

This compounding of contributions plus reinvestment is how most working-age dividend investors build retirement portfolios over 10–20 years.
