DCA Calculator
🏠 Free ToolSimulate a Dollar Cost Averaging strategy. See total invested, portfolio value, average cost basis, and return percentage with an interactive growth chart.
How it Works
Dollar Cost Averaging (DCA) is one of the most popular and effective investment strategies. Instead of trying to time the market with a single large purchase, you invest a fixed amount at regular intervals. This calculator simulates a DCA strategy and shows you the projected results over time.
Enter your investment amount per period, choose weekly or monthly frequency, set the investment duration, starting asset price, and expected annual growth rate. The calculator models the accumulation of units over time and computes your total invested amount, portfolio value, average cost basis, and overall return percentage.
The volatility parameter adds realistic price fluctuations to the simulation, demonstrating one of the key advantages of DCA: by buying at different price points, you naturally achieve a lower average cost than if you bought everything at the starting price.
The growth chart visualizes the relationship between your total invested capital and portfolio value over time. The gap between the two represents your cumulative profit, making it easy to see how compounding and regular contributions work together to build wealth.
Frequently Asked Questions
What is Dollar Cost Averaging (DCA)?
DCA is an investment strategy where you invest a fixed amount at regular intervals regardless of price. This reduces the impact of volatility and eliminates the need to time the market.
Is DCA better than lump sum investing?
Historically, lump sum investing outperforms DCA about two-thirds of the time in rising markets. However, DCA reduces risk and emotional stress, making it ideal for most investors.
How does DCA lower my average cost?
When prices drop, your fixed investment buys more units. When prices rise, you buy fewer. Over time this naturally weights your purchases toward lower prices, reducing your average cost basis.
What frequency should I use for DCA?
Monthly is the most common frequency. Weekly DCA provides slightly more averaging benefit but the difference is minimal. Choose what fits your income schedule.
Does this calculator account for volatility?
Yes. The volatility parameter adds realistic price swings to the growth simulation. Higher volatility creates larger price fluctuations, showing how DCA smooths out the impact of market turbulence.
