DCA Calculator replays a recurring buy plan on real past data (daily closes) and compares the outcome to a lump sum with the same capital.
Unlike DCA Planner: here you do not simulate the future — you measure "what if I had DCA'd?".
What is this tool?
A dollar-cost averaging backtest on historical prices.
Pick coin, amount, frequency, and lookback.
Get invested, coins, average entry, P&L, and edge vs lump sum.
How to read the results
vs lump sum = DCA P&L minus P&L from investing everything on day one.
The chart shows cumulative capital deployed vs mark-to-market value.
The table lists each historical buy (last rows if very long).
Final spot comes from the live catalog when available.
Key signals and metrics
Prices come from Binance 1D (USDT pair) via the dcc job.
Monthly = first trading day of the month in the series.
EUR converts amounts using the catalog's implicit FX.
Advanced usage and combinations
Use DCA Planner to design a forward plan; Calculator to stress-test the past.
Compare weekly vs monthly frequency on the same lookback.
Cross-check with Average Price if you want to replicate the plan with real trades.

Frequently asked questions
- Where do prices come from?
- Binance USDT daily closes stored in dcc_daily_prices (daily refresh).
- Why is a coin missing?
- Needs a *USDT pair on Binance and enough daily bars.
- Is this the same as DCA Planner?
- No — Planner = forward/scenario; Calculator = historical backtest.
Conclusion
