Futures calculators that use each exchange's real rules
Liquidation price, position size and profit for 5598 perpetual contracts on 8 exchanges. Every result uses that exchange's published formula and the contract's own margin tiers, not one rate copied across every coin.
- Liquidation priceWhere your position gets liquidated in isolated or cross mode, with the margin tier that applies at that price.
- Position sizeHow much to order so that hitting your stop loses exactly what you planned, fees included. Flags leverage that would liquidate you before the stop.
- Profit and lossNet profit after both fees, ROE on your margin, and the price you need just to break even.
- Compare exchangesOne position, every exchange: liquidation price, margin tier and funding rate side by side.

Why the exact rules matter
Exchanges set maintenance margin by tier, and they don't agree on how. A small position on a major coin might need 0.4% maintenance margin, a large one several percent, and a newly listed small-cap more still. Some exchanges measure tiers by value and some by number of contracts; some add a fee to the threshold. Calculators that use one fixed rate are close enough for a small BTC trade and drift further off as the size grows or the coin gets smaller.
PerpTiers pulls every contract's tiers from each exchange's API and shows them next to each result, so you can see which tier you are in and how much room is left before the next one.
