Work out what a grid or DCA plan actually costs before you run one. Rung spacing, the fee on a completed round trip, the spacing at which fees exactly cancel the spread, and what averaging in does to your cost basis. Real exchange fee rates built in.
| [ LEVEL ] | [ PRICE ] |
|---|
Assumes evenly spaced levels and capital split equally between them. Real fills differ: partial fills, slippage, and price leaving the range entirely all change the outcome. A grid that runs past its upper bound stops buying back, and one that falls through its lower bound is left holding the asset.
| [ BUY # ] | [ TARGET PRICE ] | [ ALLOCATED ] | [ CUMULATIVE UNITS ] |
|---|
Buying a fixed amount of money, rather than a fixed quantity, means you buy more units when the price is low and fewer when it is high. That is why the average cost sits under the plain average of the prices. It is an arithmetic property of the method, not a prediction that it will make money.
Breakeven spacing is the gap between levels at which the fees on a buy and a sell exactly eat the spread you captured.
A completed grid cycle is two trades: a buy and a sell. At a 0.25% fee per side you have paid roughly 0.5% before the spread is yours to keep, which is why a tight grid on a high-fee pair can trade constantly and still go backwards.
Adding levels narrows the gap between them. Past a point each round trip captures less than it costs, and the grid becomes a machine for paying fees. The calculator flags the point where that happens.
These numbers assume every level fills cleanly. Real markets skip, gap and stall. Running the same settings on a mock wallet or a backtest against real historical candles shows you the difference at no cost.
