DCA Backtester
Dollar-cost averaging is the simplest, most-recommended strategy for long-term crypto exposure. This tool simulates what would have happened if you had actually done it · with real Binance klines and real historical dates. Set the symbol, amount, cadence, and start date. We pull the closes and show you cost basis, current value, P&L, break-even, and the absolute and annualized return.
Simulation setup
How the simulation works
- On each cadence date, we buy
amount_usd / close_priceunits. - At end, total units × current close = market value.
- Break-even = total invested / total units.
- Annualized return =
(current_value / invested)365/days - 1
Simplifying assumptions: buy executes at daily close (no intraday slippage), no fees deducted. Real DCA has exchange fees (usually 0.1-0.2% per buy) and sometimes spread costs. We show the gross number, which is what public calculators use.
