Dollar-cost averaging is the practice of investing a fixed amount into the same asset at a fixed cadence, regardless of price.
That's it. Three components: an amount, a cadence, an asset. The discipline isn't in the formula — it's in not stopping.
Numbers below are computed from real adjusted-close SPY data at each site build.
In a roaring bull market, almost any strategy works. DCA's structural advantage shows up in sideways and choppy markets — exactly the conditions that flush out everyone trying to time the bottom.
This chart shows the same $250/month strategy applied to a flat market with the same volatility. The end result is still profit — because you bought more shares at every dip than you did at the peaks.
Crucially, this is dollar-weighted — buying more when cheap drags it down.
The constant annual rate that would have grown your principal into the end value.
The honest answer: it barely matters. Over 10+ years, every cadence converges. Pick the one you'll actually stick to.
DCA into a failed altcoin is just a slow trip to zero. You're only as good as your asset selection.
Most DCA "failures" are people who quit during the 2022 bear and missed the subsequent run-up.
Anything under 5 years isn't really DCA — it's lump-sum with extra steps and worse expected returns.
