Liquidation Price Calculator (Leveraged Futures)
Find the liquidation price of a leveraged long or short futures position (isolated margin, USDT-margined): entry price, leverage, size, maintenance margin rate and any extra margin added.
How it works
Position value N = size × entry · margin M = N ÷ leverage + extra margin · long: liquidation price = (N − M) ÷ [size × (1 − MMR)] · short: liquidation price = (N + M) ÷ [size × (1 + MMR)] · with no extra margin: long ≈ entry × (1 − 1/leverage) ÷ (1 − MMR)
On a leveraged futures or perpetual contract the exchange closes (liquidates) your position when your remaining margin falls to the maintenance margin — a small percentage of the position’s value set by the exchange for each size tier. With isolated margin only the margin assigned to that position is at risk, so the liquidation price follows from the entry price, leverage and maintenance margin rate; adding margin pushes it further away. This is the standard formula for linear (USDT- or USD-margined) contracts with no maintenance amount deduction; real liquidation can come earlier because of trading fees, funding payments and the mark price used by the exchange.
Worked example
A long of 0.5 BTC at 60,000 with 10× leverage has a value of 30,000 and needs 3,000 of initial margin. With a 0.5% maintenance margin rate the liquidation price is (30,000 − 3,000) ÷ (0.5 × 0.995) = 54,271.36 — a 9.55% drop from entry. A short with the same settings is liquidated at (30,000 + 3,000) ÷ (0.5 × 1.005) = 65,671.64.

Frequently asked questions
Why is my liquidation price closer than 100% ÷ leverage?
Because the exchange liquidates when the margin left equals the maintenance margin, not zero. At 10× a 10% move would wipe out the margin, but with a 0.5% maintenance rate liquidation comes after about a 9.5% move.
How can I move my liquidation price further away?
Lower the leverage, reduce the position size or add margin to the isolated position. Each lowers the share of the position funded by borrowed exposure.
Does cross margin change the liquidation price?
Yes. In cross-margin mode your whole account balance supports the position, so the liquidation price depends on your free balance and other open positions — enter that balance as extra margin for a rough estimate.
Why does the exchange show a slightly different number?
Exchanges use tiered maintenance rates with a maintenance amount deduction, include fees and use the mark price rather than the last trade. Use this as an estimate and rely on the exchange’s own figure.
