Grid Bot Fee Calculator - Does Your Grid Spacing Survive Fees?
A grid cycle earns the grid step and pays two fills. Fees decide whether that is profit or charity to the exchange.

How to read it
Each completed grid cycle buys one level and sells the next: gross profit is the grid step, cost is two fills of fees. At 0.1% per side, a 0.3% step hands the exchange two thirds of the gross - the classic failure mode of over-tight grids. Community tests on Pionex found ~0.24% spacing annualizing near 29% while 1000-grid setups annualized near 12% on the same range: more cycles, less per cycle, more fees. Compare real fee schedules in the comparison table.
Model and assumptions
A cycle is modeled as buying one grid level and selling the next, fees on both fills at your per-side rate: net = order x ((1+step) x (1-fee) - (1+fee)). The break-even step is exact: 2 x fee / (1 - fee). Range mode splits your investment evenly across the grids (order size = investment / grids) and computes every level. Grid profit projections assume cycles keep repeating at your estimate with constant volatility - regime changes break that assumption. Unrealized position P&L is not included: when price leaves the range, the whole position bags (all quote at the top, all base at the bottom).
