What Is Dollar-Cost Averaging?
Dollar-cost averaging (DCA) is the practice of investing a fixed dollar amount at regular intervals—regardless of market conditions.
Think of it like filling a bathtub. When using DCA, you don’t predict when water pressure will be perfect—you leave the faucet running at a steady pace.
Why DCA Works
Study after study shows that time in the market beats timing the market. J.P. Morgan research found that missing just the 10 best trading days over 20 years cut returns by more than 50%.

FAQ
Is DCA better than lump sum?
Statistically, lump-sum wins ~65% of the time. But DCA provides psychological benefits and is excellent for income-based investing.
What happens if the market crashes?
That is ideal—you buy more shares at lower prices, improving long-term returns.
How often should I invest?
Monthly is the sweet spot for most people.
What’s the minimum?
No minimum—some platforms allow $5 or $1. Start with what you can afford.

DCA is not flashy, but it builds substantial wealth while you sleep peacefully. Set up automation today, pick a broad index fund, decide an amount, then stop thinking about it.
