Dollar-cost averaging is less a strategy and more a discipline: invest the same amount, on the same day, every month. Its power isn't market timing — it's that it removes timing from the equation entirely.
Why a fixed schedule works
By investing on a schedule, you buy more shares when prices are low and fewer when they're high, automatically lowering your average cost. You never need to predict the market — you simply keep feeding the plan, and compounding does the heavy lifting over time.
The compounding machine
Every monthly contribution starts compounding immediately, and earlier contributions earn returns for longer. That's why the projection's profit column grows faster than the contribution column the longer the horizon — the definition of compound growth.
Where it falls short
If you already have a lump sum, investing it immediately has historically beaten spreading it out — more time in the market wins on average. DCA's real value is making consistent investing automatic and emotionally sustainable, which for most people matters more.
Frequently asked questions
Investing a fixed amount of money on a regular schedule regardless of the price — buying more shares when prices are low and fewer when they're high, which smooths your average entry price.
Statistically, lump sums tend to win when the market rises, but DCA wins on psychology and works well when money arrives as regular income. For most people, regular investing is the realistic option.
At a typical 7–8% annual return, the profit portion eventually exceeds your contributions — often within 15–20 years, and dramatically beyond.
