Dollar-Cost Averaging — The Best Strategy for New Investors

If you’ve ever hesitated to invest because the market seemed “too high” — you’ve experienced the problem that dollar-cost averaging (DCA) solves. It’s one of the few investing strategies that almost every financial researcher agrees is superior to timing the market.

What Is Dollar-Cost Averaging?

DCA means investing a fixed amount at regular intervals regardless of market conditions. Instead of investing $1,200 all at once, you invest $100 every month for 12 months. You buy more shares when prices are low and fewer when prices are high — which automatically lowers your average cost over time.

A Simple Example That Shows Why It Works

The investor spent $600 and owns shares worth $812 — even though prices fell sharply in months 2 and 3. By buying more shares when prices were low, the average cost per share came in below the average price. This is the mathematical advantage of DCA.

DCA vs Lump Sum — What the Research Says

Vanguard’s research found that lump-sum investing outperforms DCA about two-thirds of the time in rising markets. But here’s the catch: most people don’t have a large lump sum available. They earn income monthly. For regular investors contributing from their paycheck, DCA isn’t a strategy choice — it’s the only realistic option.

More importantly, DALBAR’s annual study consistently shows that average investors underperform the market index by 1.5–3% per year — because they buy high and sell low emotionally. DCA mechanically prevents this.

How to Set Up Automatic DCA in 10 Minutes

1. Open your brokerage account (Webull, Fidelity, or Questrade)
2. Navigate to “Automatic Investments” or “Recurring Purchases”
3. Select your ETF (VTI, VOO, or XEQT for Canadians)
4. Set the dollar amount ($50–$200 recommended for beginners)
5. Set the frequency (monthly aligns with most pay schedules)
6. Confirm — your DCA is now automated permanently

DCA for Crypto

DCA works especially well for volatile assets like Bitcoin and Ethereum. Kraken’s Recurring Buy feature lets you set up automatic purchases on a daily, weekly, or monthly schedule — removing the emotional challenge of buying volatile assets.

The Bottom Line

Set up automatic monthly contributions to a low-cost index ETF. Don’t change the amount when markets drop. Don’t cancel it when markets rally. This single discipline, maintained for 20 years, will outperform most actively managed strategies — and most professional fund managers.
