Crypto liquidation price calculator

Estimate the price at which an isolated-margin position on a USDT-margined perpetual is liquidated. Enter the direction, the entry price, the leverage and the maintenance margin rate of your tier — the calculator returns the liquidation price, its distance from the entry and the bankruptcy price. Add the position size to see the margin amounts and what adding margin does.

Direction

Lowest tier on major exchanges: typically about 0.3–0.5% for BTC and ETH and around 1% or more for most altcoins; large positions fall into higher tiers. Check your exchange's margin tiers table.

Needed only for the margin amounts and to add margin.

Isolated margin you add on top of the initial margin.

An estimate for isolated margin on linear USDT-margined perpetuals. The real liquidation price depends on your exchange's maintenance-margin tiers, on the mark price rather than the last price, and on fees and funding — check the order form before you trade. Not financial advice.

How to use the calculator

  1. Choose long or short and enter the entry price (for an open position, the average entry your exchange shows).
  2. Enter the leverage and the maintenance margin rate (MMR) of your position's tier — it is in your exchange's margin tiers or risk limits table; 0.5% is a conservative starting point for BTC and ETH.
  3. Optionally enter the position size in coins to see the position value, the initial margin and the maintenance margin at liquidation.
  4. With the size entered, add the isolated margin you plan to put on top of the initial margin to see how far it moves the liquidation price. Keep the stop-loss well before that price.

How the liquidation price is calculated

An isolated position is liquidated when its equity — the margin plus the unrealised PnL — falls to the maintenance margin, a small share of the position value set by the maintenance margin rate (MMR). The higher the leverage, the thinner the margin and the closer that price. Margin added to the position pushes it further away. The bankruptcy price is where the margin would be exactly gone; exchanges liquidate a little before it and base their liquidation fee on it. Fees, funding and the "maintenance amount" of a tier are ignored.

  • Position margin = Entry × Quantity ÷ Leverage + Added margin
  • Liquidation (long) = (Entry × Quantity − Position margin) ÷ (Quantity × (1 − MMR))
  • Liquidation (short) = (Entry × Quantity + Position margin) ÷ (Quantity × (1 + MMR))
  • Without added margin, long = Entry × (1 − 1 ÷ Leverage) ÷ (1 − MMR)
  • Without added margin, short = Entry × (1 + 1 ÷ Leverage) ÷ (1 + MMR)
  • Bankruptcy price (long) = Entry × (1 − 1 ÷ Leverage) − Added margin ÷ Quantity (+ for a short)
  • Distance % = |Entry − Liquidation| ÷ Entry × 100

Worked example

A long on BTC at 100,000 with 10× leverage, isolated margin; the maintenance margin rate of the lowest tier is 0.5%.

The margin would be exactly gone at 100,000 × (1 − 1/10) = 90,000 — the bankruptcy price. Liquidation comes a little earlier, when the equity equals the maintenance margin: 90,000 ÷ (1 − 0.5%) = 90,452.26, that is 9.55% below the entry.

A short from the same price is liquidated at 110,000 ÷ (1 + 0.5%) = 109,452.74 — 9.45% above the entry. At 100× leverage the long is liquidated at 99,000 ÷ 0.995 = 99,497.49, only 0.50% away from the entry: an ordinary intraday move.

With a position size of 0.05 BTC the initial margin is 5,000 ÷ 10 = 500 USDT. Add 200 USDT of margin and the position is backed by 700 USDT; the liquidation price moves down to 86,432.16, 13.57% below the entry.

Questions and answers

Why does my exchange show a different liquidation price?

Several reasons, each usually small. Maintenance margin rates are tiered — a bigger position falls into a higher tier with a higher rate, and some exchanges subtract a "maintenance amount" that smooths the step between tiers. Exchanges liquidate on the mark price, not on the last traded price. The liquidation fee and sometimes the closing fee are reserved out of the margin, and funding payments change the margin while the position is open. If the exchange's number differs a lot, check the tier you are in and the margin mode.

What is the maintenance margin rate and where do I find it?

It is the minimum equity, as a share of the position value, that the exchange requires to keep the position open; below it the position is liquidated. The rate is set per contract and per position-size tier. As of October 2026 the lowest tier for BTCUSDT and ETHUSDT perpetuals is 0.33% on Bybit and 0.4% on OKX, with 0.5% in the next tier on both; DOGEUSDT starts at 0.75% on Bybit, and most altcoins start around 1% or more. Larger positions move into higher tiers. Look for "margin tiers", "risk limits" or "leverage & margin" in your exchange's trading rules — the order form usually shows the current tier.

Does adding margin move the liquidation price?

Yes, on isolated margin. Added margin raises the equity, so the price has to travel further before the equity falls to the maintenance margin: in the example above, 200 USDT added to a 0.05 BTC position moves the liquidation price from 90,452.26 to 86,432.16. The effective leverage of the position drops at the same time. Removing margin does the opposite.

Does this work for cross margin?

No. In cross margin the position is backed by the whole available balance of the account and by the unrealised PnL of your other positions, so its liquidation price depends on everything else in the wallet and changes whenever any of it moves. This calculator is for isolated positions; for cross margin use the price your exchange shows and keep the stop well before it.
