Estimate only. Real exchanges apply tiered maintenance margin, fees, and funding, so the actual liquidation price will differ. Cross-margin mode also depends on your full account balance and is not modeled here.
How this works
For an isolated-margin, USDT-margined linear perpetual, the liquidation price is approximately:
MMR is the maintenance margin rate — the fraction of position value an exchange needs you to keep posted as collateral before forcing liquidation. The default here is 0.5%, which is in the ballpark of major venues for small to medium positions. Real venues use tiered rates that scale up with position size, and they also subtract trading and funding fees from your margin, so the actual liquidation price will be slightly worse than the estimate.
This calculator only models the isolated-margin case, where each position has its own dedicated collateral. Cross-margin liquidation depends on your full account balance and any unrealized P&L on other positions, and is not modeled here.
FAQ
What does this calculator actually compute?
It estimates the price at which an isolated-margin, USDT-margined linear perpetual would be liquidated, using the textbook formula entry × (1 − 1/L + MMR) for longs and entry × (1 + 1/L − MMR) for shorts. The default maintenance margin rate is 0.5%, which you can override.
Why does my exchange show a slightly different number?
Real exchanges apply tiered maintenance margin (larger positions face higher MMR), trading and funding fees, and sometimes insurance-fund contributions. Those move the actual liquidation price a little above or below this estimate, especially at high leverage or for very large positions.
Does this work for cross-margin positions?
No. Cross-margin liquidation depends on your entire account balance and any unrealized P&L on other positions. This calculator only models the isolated-margin case, where each position has its own dedicated collateral.
Can I use it for very small or very large prices?
Yes. The entry-price field accepts numbers like 0.00000123 (memecoin-scale) and 70000 (BTC-scale). Output decimals adapt to the size of the value so small prices never round to zero.
Where do the live prices come from?
When you pick a coin from the search box, the page proxies a request to CoinGecko on the server. Live price is purely a convenience — the calculator works fully even with the network call disabled.
