What Is Dollar-Cost Averaging?
Dollar-cost averaging (DCA) means investing a fixed dollar amount at regular intervals, say, $200 every month, no matter what the market is doing. You don't try to time the market or wait for a dip. You just invest consistently.
It sounds almost too simple. That's the point.
How It Works in Practice
Let's say you invest $500/month into XEQT:
- Month 1: XEQT at $30/share → you buy 16.7 shares
- Month 2: Market drops, XEQT at $25/share → you buy 20 shares (more for the same money)
- Month 3: Market recovers, XEQT at $32/share → you buy 15.6 shares
Because you buy more shares when prices are low and fewer when prices are high, your average cost per share ends up lower than the average market price over that period. This is the mathematical edge of DCA.
Why It Beats Trying to Time the Market
Professional fund managers, with teams of analysts and decades of experience, consistently fail to beat the market over the long term. Individual investors who try to time when to buy and sell do even worse, largely because emotion drives decisions at the worst possible moments (selling during crashes, buying during peaks).
DCA removes emotion from the equation. You invest on schedule. The market goes up, great. The market goes down, also fine. You're buying more shares at a discount.
The Psychological Benefit
One underappreciated advantage of DCA: it makes market downturns feel less scary. When you know your next automatic contribution is coming regardless, a market drop feels like a sale rather than a disaster. This psychological reframe helps investors stay the course instead of panic-selling.
Setting It Up in Canada
Most Canadian investing platforms make DCA easy:
Wealthsimple: Set up a recurring deposit from your bank account and automatic investment into your chosen ETF. Takes about five minutes to configure.
Questrade: Set up automatic deposits; you'll need to place the buy order manually (or set up a pre-authorized contribution to their robo-advisor service).
Your bank's RRSP/TFSA: Most allow pre-authorized contributions on a monthly schedule.
A Realistic Example
An Ottawa resident who contributes $400/month to a TFSA invested in XEQT starting at age 28:
- Total contributed by age 58 (30 years): $144,000
- Estimated portfolio value at ~7% average annual return: ~$460,000
- Tax-free, assuming the TFSA limit covers the growth
The key isn't the exact number: it's that steady, boring, automatic contributions compounded over decades build real wealth.
Ottawa Context
Many Ottawa residents, federal employees, healthcare workers, tech professionals, have bi-weekly paycheques that make a rhythm of automatic investing easy to sustain. Setting up an automatic transfer the day after each paycheque hits means you invest before you have a chance to spend it. Even $150 or $200 per pay period adds up to $3,900–$5,200 per year without any conscious effort.
Common Mistakes to Avoid
- Stopping during downturns: This defeats the purpose. Downturns are when DCA helps most.
- Watching your balance daily: Check quarterly at most. Short-term noise creates anxiety that leads to bad decisions.
- Waiting for the "right" time: There is no right time. Start now with whatever amount you can afford.
Bottom Line
Dollar-cost averaging won't make you rich overnight. It will, consistently and reliably, build substantial wealth over time, with minimal stress and zero market expertise required. Set it up, automate it, and get on with your life.
