Calculate the outcome of a dollar-cost averaging strategy for any asset. Enter your investment amount, frequency, and price range to see average cost basis, portfolio value, ROI, and how DCA compares to a lump-sum investment.
Buying $100 of BTC weekly as the price doubled from $30K to $65K results in a ~61% return vs 116% for a perfect lump sum — but DCA removed the timing risk.

DCA is an investment strategy where you invest a fixed amount at regular intervals regardless of price. By buying more units when prices are low and fewer when prices are high, you average out your cost basis and reduce the impact of volatility and poor timing.
Research shows lump-sum investing outperforms DCA roughly two-thirds of the time in rising markets, simply because more money is invested sooner. DCA's advantage is psychological and risk-management: it removes the need to time the market and reduces regret from a single badly-timed purchase.
Your average cost basis is the mean price you paid per unit across all purchases. If the current price is above your cost basis, you're in profit; below it, you're at a loss. Cost basis also determines your taxable gain when you sell.
Prices between your first and last purchase are linearly interpolated — each purchase occurs at a price that moves in equal steps from start to end. This simulates a smooth trend. Real markets are more volatile, so your actual average cost basis may differ.
