This models a straight-line price path between your start and end price to illustrate how dollar-cost averaging smooths your entry cost. It's a simplification, not a historical backtest — real prices don't move in a straight line.

Dollar-cost averaging is a way of removing the pressure to time an entry perfectly. Instead of committing a lump sum at a single price, you spread the same total investment across several smaller buys over time — weekly, monthly, or on whatever schedule fits your plan.

The mechanical effect is that a fixed dollar amount buys more units when the price is low and fewer units when the price is high, which pulls your average cost per unit toward the middle of the range rather than anchoring it to whatever the price happened to be on day one. Over a volatile asset like crypto, that can meaningfully reduce the damage of buying right before a drop.

This calculator models a simplified straight-line price path between a starting and ending price so you can see the mechanics clearly — real markets move in swings, not straight lines, so treat the output as an illustration of the DCA effect rather than a prediction or backtest of any specific asset.

FAQ

What is dollar-cost averaging (DCA)?
DCA means investing a fixed dollar amount at regular intervals, regardless of price. Instead of trying to time a single entry, you buy consistently, which naturally buys more units when prices are low and fewer when prices are high.
Does DCA guarantee a profit?
No. DCA reduces the impact of entry timing and volatility, but if the asset's price trends downward over the full period, average cost will still be underwater. It's a risk-management approach, not a guaranteed-return strategy.
How often should I DCA?
There's no fixed answer — weekly and monthly are both common. More frequent buying smooths price fluctuations further but may carry more transaction fees depending on the platform.
