DCA: How to Know If Your Strategy Actually Beats the Market
You've been buying Bitcoin every Monday for 2 years. Great, that's a solid strategy. But can you answer this question: does your DCA beat a simple lump sum purchase?
If you can't answer, you're not tracking your performance properly.
The DCA tracking problem
DCA (Dollar Cost Averaging) is the most recommended strategy for long-term investors. The principle is simple: invest a fixed amount at regular intervals, regardless of price.
But tracking is a nightmare:
- Dozens of purchases at different prices → impossible to calculate average price in your head
- Multiple assets in DCA → BTC, ETH, S&P 500... how do you compare?
- Irregular deposits → some months you invest more, others less
- What's my real performance? Classic ROI doesn't work with DCA
XIRR: The metric built for DCA
XIRR was literally invented for this use case. It takes each cash flow (date + amount) and calculates your annualized return. It's the standard used by investment funds to measure their performance.
With XIRR, you can finally say: "My Bitcoin DCA earns me 18.7% per year". And you can compare that directly to a World ETF (8-10% / year historically).

3 metrics to monitor
Here are the 3 essential metrics for a DCA investor:
- Global XIRR: Your annualized performance across all assets
- XIRR per asset: Identify which DCA performs best
- % of capital per asset: Verify you're not overexposed to a single asset
DCA is a strategy of patience. But patience without measurement is just hope. And hope is not a trading strategy.
