What Is Dollar-Cost Averaging?

Detailed Explanation
Instead of trying to guess the “best” moment to invest a lump sum, dollar-cost averaging spreads your purchases out. When prices are lower, your fixed contribution buys more shares; when prices are higher, it buys fewer. Over time this averages out your cost per share.
The main benefit isn't necessarily a higher return — in markets that trend upward over time, investing a lump sum immediately has, on average historically, outperformed spreading it out. The real benefit of dollar-cost averaging is behavioral: it reduces the emotional difficulty of investing during downturns and helps build a consistent habit, which matters most for people investing regularly from a paycheck rather than from a single windfall.
For most beginners contributing from regular income, dollar-cost averaging happens naturally simply by investing a portion of every paycheck — there's no need to overthink the timing.
