What is DCA? Dollar-Cost Averaging Explained for Canadian Investors

DCA is an acronym for dollar-cost averaging. It is an investment strategy that involves investing a fixed amount of money at regular intervals, such as weekly, biweekly, or monthly, rather than making a single lump-sum investment.

In Canada, this can take the form of a recurring contribution linked to each pay period. The key is making contributions over time, regardless of short-term market fluctuations, rather than timing the market. Dollar cost averaging (DCA) can be implemented in non-registered and registered accounts, including RRSPs, TFSAs, RESPs, and FHSAs, depending on individual investment goals. However, DAS does not eliminate risk, prevent losses, or guarantee returns.

What Does DCA Mean in Investing?

DCA stands for dollar-cost averaging, which is a type of investment strategy. It may also be referred to as periodic investing or scheduled investing. DCA works by investing the same amount of money at a set interval, regardless of market conditions. Over time, this will often look like fewer shares purchased when purchase prices are higher and more shares purchased when prices are lower.

The idea behind this investment strategy is to avoid predicting short-term market volatility, but rather maintaining consistency through different market conditions.

How Dollar-Cost Averaging Works

Dollar-cost averaging works by investing a fixed amount on a consistent schedule. The table below outlines an example of how this may look:

While the contribution of $200 remains the same across all four months, the number of units purchased changes based on price fluctuations. This showcases how market risk exposure is spread across different asset prices, rather than being concentrated into a single moment of time.

One thing to remember, however, is that this investment strategy will not predict outcomes or reduce risk entirely. Instead, market performance will still determine overall results.

DCA vs. Lump-Sum Investing

When talking about investing in Canada, DCA is often compared to lump-sum investing strategies, where an amount of money is invested at a single point in time. Below, the table outlines the differences between these two strategies, including potential advantages and disadvantages:

Research by Vanguard (opens in a new tab) indicates that lump-sum investing has historically outperformed cost-dollar averaging, approximately two-thirds of the time, as markets tend to rise over time.

That said, the choice depends on the investor, and should not be based on historical market performance alone. While some investors prefer a long-term investing strategy, lump-sum investing may be preferred by investors who have larger capital available upfront.

Potential Benefits of Dollar-Cost Averaging

Long-term investors often use dollar-cost averaging due to how the investment structure is laid out for them, and for other possible benefits.

It may reduce the pressure to time the market

As dollar-cost averaging involves regular investing made during a set schedule, it may reduce the pressure to make short-term investment decisions.

It may build a consistent investing habit

Regular investment intervals may help investors form a long-term contribution habit.

It may help manage emotional investing

A fixed investment strategy may reduce emotional reactions during market volatility.

It can work with many investment types

Dollar-cost averaging (DCA) can be used across exchange-traded funds (ETFs), stocks, mutual funds, bonds, and other assets.

It can fit Canadian registered accounts

Dollar-cost averaging can be used when investing in TFSAs, RRSPs, FHSAs, RESPs, and non-registered accounts, depending on eligibility.

Potential Risks and Limitations of DCA

According to CIRO (opens in a new tab), market volatility is a natural part of investing, and no one can predict market movements with certainty. As with any investment strategy, dollar-cost averaging (DCA) carries risk.

• DCA does not prevent losses: Losses can still occur in declining market prices.

• It may underperform lump-sum investing: Because less capital is exposed to market conditions earlier on, it may underperform lump-sum investing in rising markets.

• Fees can reduce returns: If each contribution triggers a transaction cost, returns may be reduced, especially when investing more regularly.

• Dollar-cost averaging does not address portfolio diversification or investment selection: A poorly chosen investment may not improve, even when spreading out contributions over time.

Ultimately, investors should understand their risk tolerance before investing in any assets.

Dollar-Cost Averaging in Canada

Dollar-cost averaging can be used across various registered and non-registered accounts in Canada. The table below outlines the various accounts and how DCA strategies may be used.

Who Commonly Uses DCA?

Dollar-cost averaging investment strategies may be used by investors who prefer a structured investment approach that is consistent over time.

DCA is commonly used by investors if:

• Income is collected regularly.

• Automatic investments are preferred.

• Long-term investment goals.

DCA may be less commonly used by investors if:

• Large sums of money are available and ready to be invested.

• Short-term access to funds is required.

• High-interest debt exists.

• Short-term gains are expected.

How to Start a DCA Investing Strategy

While investing journeys may differ, setting up a dollar-cost averaging strategy generally follows the following steps:

1. Set a financial goal: This may include retirement planning, education, or other long-term saving objectives.

2. Choose account type: Choose between a TFSA, RRSP, FHSA, RESP, or a non-registered account.

3. Decide on contribution amount: Investors may consider available cash flow, household budgets, and payment schedules.

4. Choose a contribution schedule: Common contribution schedules often consist of weekly, biweekly, or monthly.

5. Choose investments: Investments may be chosen based on financial objectives, time horizons, and risk tolerance.

6. Automate contributions: Some investors opt to automate contributions to remain consistently investing.

7. Review periodically: Investors may also review investment portfolio performance over time.

Example: Investing $300 per Month Using DCA

Imagine an investor contributes $300 monthly from their paycheque into the same investment for the next four months. In the first month, the unit price is $30, which buys them 10 units. In the second month, the price drops to $25, which means the same amount buys them 12 units. In the third month, the price increases to $35, so the contribution only buys 8.5 units. And finally, in the fourth month, the price lowers to $28, which buys them 10.7 units.

Over the four-month period, $1,200 is invested. While the contribution amount remained the same, the number of units purchased changes, depending on the price when each contribution was made. This illustrates that instead of investing at a single price point, the investments are made in different market conditions, which is precisely how dollar-cost averaging functions.

Common DCA Mistakes

Although DCA is fairly straightforward, misconceptions may still happen among first-time investors:

• Assuming DCA guarantees profit: Market risk remains, regardless of when the contribution is made.

• Ignoring fees: Frequent contributions may lead to higher fees depending on which account or investment platform is used.

• Short-term money needs: Dollar-cost averaging is often associated with longer time horizons, while short-term cash requirements may require a different investment process.

• Forgetting registered account contribution limits: Contribution limits in registered accounts should not be forgotten, as over-contribution penalties can occur.

Conclusion: Dollar Cost Averaging (DCA)

Dollar-cost averaging (DCA) is an investment approach that involves making fixed-amount contributions over regular intervals over time. A core idea of DCA is consistently investing, regardless of market conditions, rather than focusing on market timing.

That said, like all investment strategies, DCA does not eliminate risk, prevent losses, or guarantee returns. Returns are also influenced by fees, market conditions, investment choices, and time horizons.

In Canada, this investment approach can be used across accounts, such as TFSAs, RRSPs, FHSA, RESPS, and other non-registered accounts. Although how DCA works will remain the same, contribution limits, taxes, and eligibility will vary between accounts.

Ultimately, dollar-cost averaging is one of several investment approaches used in Canada. The choice of approach will depend on individuals' circumstances, including risk tolerance, investment timelines, and financial goals.
