Dollar-cost averaging: the lazy way that often works
Investing the same amount every month removes the need to time the market. It also reduces regret, which matters more than people think.
Written for plain-English understanding by Joseph Citizen. Why I built this →
Dollar-cost averaging means investing a fixed amount on a regular schedule — say $300 every two weeks — instead of trying to time when prices are low.
What actually happens
Because you invest the same dollar amount each time, you automatically buy more shares when prices are low and fewer when prices are high. Over time, your average cost per share lands in the middle of the market's range.
Does it produce the highest returns?
Not always. If markets generally rise — which they have over long periods — investing one big lump sum at the start usually beats spreading it out, because the money has more time to grow.
But most people do not have a lump sum. They have a paycheck. Dollar-cost averaging is what happens automatically when you contribute to a 401(k) every two weeks. That is its real power.
Why it helps psychologically
Investing during scary markets is hard. A scheduled, automatic investment removes the decision. You stop checking the price. You stop second-guessing. The boring discipline is the whole point.
