What Is Dollar-Cost Averaging (DCA)? The Beginner's Strategy That Actually Works
Dollar-cost averaging (DCA) is one of the most recommended investing strategies in the world — and one of the simplest. Instead of trying to time the market, you invest a fixed dollar amount at regular intervals regardless of what the market is doing. Over time, this smooths out your average purchase price and removes the emotional guesswork from investing.
How Dollar-Cost Averaging Works
Say you invest $500 every month into an S&P 500 ETF. Some months the price is high and your $500 buys fewer shares. Some months it's low and your $500 buys more. Over time, you accumulate shares at a lower average cost than the peak prices — without needing to predict the market.
| Month | ETF Price | Invested | Shares Bought |
|---|---|---|---|
| January | $50.00 | $500 | 10.00 |
| February | $40.00 | $500 | 12.50 |
| March | $35.00 | $500 | 14.29 |
| April | $45.00 | $500 | 11.11 |
| May | $55.00 | $500 | 9.09 |
| Total | Avg listed: $45.00 | $2,500 | 56.99 shares |
Average price actually paid: $2,500 ÷ 56.99 = $43.87/share — lower than the simple $45.00 average price over the period.
Why DCA Works Psychologically
Beyond the math, DCA solves a real human problem: we make terrible decisions when scared or greedy. The 2020 COVID crash saw millions sell at the bottom. Investors who kept buying monthly automatically bought at the cheapest prices of the decade. DCA removes the decision — and that discipline, compounded over 10–30 years, is extraordinarily powerful.
DCA vs Lump Sum
Research consistently shows lump sum investing outperforms DCA about two-thirds of the time in upward-trending markets — money invested earlier compounds longer. But DCA is better when you're investing from regular paycheques (most people don't have a lump sum ready), or when you can't psychologically stomach watching a large lump sum drop 30% immediately after investing.
How to Start DCA in Canada
- Choose an account: TFSA or RRSP.
- Choose a broad-market ETF: XEQT, VEQT, or VFV are excellent for beginners.
- Set a fixed monthly amount: $200, $500, $1,000 — whatever is sustainable.
- Automate it: Most Canadian brokerages allow scheduled automatic purchases.
- Don't touch it: The strategy only works if you stay consistent through downturns.
Set your DCA purchase to execute 1–2 days after each paycheque. Pay yourself first — invest before you spend.
Bottom Line
DCA won't make you rich overnight. What it will do is build wealth consistently, reduce emotional mistakes, and ensure you're always invested — which is more than most retail investors manage.
