About Dollar Cost Averaging Calculator
Dollar cost averaging is one of the most popular investment strategies, especially for volatile assets like cryptocurrency. This calculator simulates regular purchases over time and shows you exactly how DCA affects your average cost basis and overall returns.
How the Simulation Works
Enter how much you want to invest per period (daily, weekly, or monthly), the number of periods, and a starting and ending price. The calculator maps a linear price path between those two points and computes each purchase: units bought, running total, and cumulative investment. The result is your total position value, average cost basis, and net profit or loss.
Why DCA Works
When you invest a fixed amount, you automatically buy more units when prices dip and fewer when prices spike. This smooths out your entry point and reduces the risk of putting all your money in at the worst possible time. It is particularly effective for long-term accumulation strategies. To see how a single lump sum investment would have performed instead, try the Crypto Profit Calculator.
Reading the Results
The summary cards show your total invested amount, current portfolio value, average cost per unit, and ROI percentage. Expand the purchase breakdown to see each individual buy with its price and units. For projecting how your accumulated position might grow with compound returns, the Compound Interest Calculator is a good next step. All calculations run locally in your browser.
Frequently Asked Questions
What is dollar cost averaging?
Dollar cost averaging (DCA) means investing a fixed amount at regular intervals regardless of the asset's price. You buy more units when prices are low and fewer when prices are high. Over time this tends to lower your average cost basis compared to investing a lump sum at a single point.
How does the price simulation work?
The calculator uses a linear price path between your starting and ending prices. While real markets are more volatile, this gives you a useful approximation of how DCA performs when an asset moves from one price level to another.
Is DCA better than lump sum investing?
It depends on market conditions. Studies show lump sum investing outperforms DCA about two-thirds of the time in rising markets, since your money is invested longer. DCA works well psychologically and reduces the risk of buying at a peak. It is especially popular for volatile assets like crypto.
What does average cost basis mean?
Your average cost basis is the total amount invested divided by total units purchased. If you bought 0.5 BTC at $30,000 and 0.5 BTC at $40,000, your average cost basis is $35,000 per BTC. You profit when the current price exceeds your cost basis.
Can I use this for stocks or just crypto?
This works for any asset with a fluctuating price, including stocks, ETFs, crypto, or commodities. The math is the same regardless of what you are buying.
