Grid Profit Simulator

How to use this grid profit simulator

Type in four numbers and you get a result. The lower and upper bounds are the price band you want the bot to buy and sell back and forth in — for example, if you reckon BTC will grind between 58k and 72k in the near term, put those two in. The grid count decides how densely the grid orders are placed: the more grids, the smaller the gap between each one, the more frequent the fills, but the thinner each grid earns. Total capital is how much USDT you're putting into this one grid. That last field, "fills," is the most subjective item in the tool: it means how many times price crosses the grid lines back and forth inside the range and triggers a "buy-low, sell-high" pairing. You can only estimate it from your read of how active the market is — the choppier and more active, the bigger this number.

The big number on the dark card on the right is the total, taking the net profit of each pairing times the number of fills you estimated. The two comparison bars below it matter: the top one is the gross spread per grid, the bottom one is the part the fees eat. If you crank the grid count very tight, you'll see the fee bar stretch longer and the gross bar shrink — that's the visual reason a grid set too tight stops making money.

Where the money in a grid actually comes from

A grid doesn't predict up or down; it earns from volatility itself. The bot lays a row of buy and sell orders across the range; when price moves down it fills buys, when it moves up it fills sells, and each completed "buy low first, sell high after" locks in a small profit. So what it fears most isn't a drop — it's no movement: price frozen and not swinging, or breaking straight out of the range one-way, and the grid stalls or gets stuck. How much each grid can earn equals that grid's price-spread percentage, minus two fees for the buy and the sell (which is why the formula multiplies the fee by 2). For how grids work on Binance, see Binance Academy's grid trading explainer.

Here's a counterintuitive point: more grids isn't better. With grids too tight, the per-grid spread may not even cover the two fees, so that grid works for nothing or even loses; with grids too sparse, you miss the small swings. A genuinely sensible spacing has to make the per-grid gross clearly outweigh the fees — which is exactly what the Grid Parameter Calculator works out for you in reverse.
