Crypto Futures Liquidation Price: How to Calculate It

What your liquidation price tells you

Your crypto futures liquidation price is the estimated level at which an exchange may forcibly reduce or close a leveraged position because its margin can no longer meet the required minimum. It is not a planned exit. For a long, liquidation is below your entry price; for a short, it is above. The exact trigger depends on the exchange’s rules and the margin available to the position.

This guide uses USDT-margined perpetual futures in isolated margin mode. In isolated mode, you can work through one position’s margin. In cross margin mode, other positions, open orders and the shared wallet balance can affect the result, so a simple entry-and-leverage formula is not enough. (mexc.com)

Risk reminder: Leveraged futures can be liquidated quickly, and a calculated liquidation price is not a guarantee of how much you will lose.

Gather the numbers before calculating

You need five inputs:

• Entry price: Your average filled price, not the price you hoped to get.
• Position quantity: The amount of the asset your contract represents. If the exchange shows contracts instead, multiply the contract count by the size of each contract.
• Position margin: The USDT assigned to this isolated position. Initially, this is approximately entry price × asset quantity ÷ leverage; adding or removing margin changes it.
• Maintenance margin: The minimum required to keep the position open. For the simplified MEXC calculation, multiply entry price × asset quantity × the contract’s maintenance margin rate.
• Direction: Whether you are long or short.

Look up the maintenance margin rate for your specific contract and position-size tier. On MEXC, larger risk tiers can have higher rates; the rate is not simply your chosen leverage divided by a fixed number. Fees are left out of the hand calculation below. (mexc.com)

Calculate an isolated long or short

First, calculate position margin and maintenance margin. Then use the difference between them—the margin available to absorb a price move—to estimate how far price can move against you. These simplified formulas follow MEXC’s published isolated-margin calculation and exclude its liquidation fee. (mexc.com)

• Long liquidation price = entry price − [(position margin − maintenance margin) ÷ asset quantity].
• Short liquidation price = entry price + [(position margin − maintenance margin) ÷ asset quantity].

Suppose you open 0.01 BTC at 50,000 USDT per BTC with 10× leverage, using isolated margin. Assume, for this example only, that the applicable maintenance margin rate is 0.5% and that no extra margin has been added.

1. Position value = 50,000 × 0.01 = 500 USDT.
2. Position margin = 500 ÷ 10 = 50 USDT.
3. Maintenance margin = 500 × 0.005 = 2.50 USDT.
4. Margin available above maintenance = 50 − 2.50 = 47.50 USDT.
5. Price distance = 47.50 ÷ 0.01 = 4,750 USDT per BTC.

The estimated long liquidation price is 45,250 USDT: 50,000 − 4,750. For the same-sized short, it is 54,750 USDT: 50,000 + 4,750. This is why saying “10× leverage means liquidation exactly 10% away” is misleading. Maintenance margin consumes part of the initial buffer; the estimate here is 9.5% from entry, before the omitted liquidation fee and other adjustments.

If you add 20 USDT of isolated margin without changing the position, the simplified buffer rises to 67.50 USDT. The long estimate moves down to 43,250 USDT and the short estimate up to 56,750 USDT. That creates more room for price to move, but it also puts another 20 USDT at risk. Adding margin is not a substitute for deciding how much you are willing to lose.

Why your exchange may show a different price

Treat hand calculations as a check, not as the authoritative live figure. Several things can change the displayed liquidation price:

• Liquidation fees and trading costs: MEXC’s full liquidation condition includes a liquidation fee. Opening and closing trading fees depend on the contract, order type and applicable fee schedule; do not assume a zero-fee trade. (mexc.com)
• Funding payments: Paying funding can reduce the funds supporting a position. Funding settlement times vary by pair, so check the contract’s displayed rate and countdown rather than assuming every contract settles on the same schedule. (mexc.com)
• Position changes: Adding to or reducing a trade changes its quantity and may change its average entry price or risk tier. Adding or removing isolated margin also changes the calculation. (mexc.com)
• The trigger price: MEXC uses its fair price to assess liquidation, not simply the latest trade printed on a candle. A chart’s last price and the fair price can differ. (mexc.com)

Before placing an order, compare your estimate with the exchange’s futures calculator. After it fills, check the liquidation price shown for the actual position, and recheck it after changing size or margin. MEXC describes its calculator results as estimates. (mexc.com)

Plan the stop before the liquidation level

A liquidation price answers, “How far can this position move before the exchange intervenes?” A stop-loss answers a different question: “Where is my trade idea no longer valid?” Set the stop around your trade’s structure, then size the position so a stop-out fits your risk budget. Leave room between the stop and liquidation level; a stop that triggers only after liquidation offers no useful protection.

In the example above, a long entered at 50,000 USDT with a planned stop at 48,500 USDT risks approximately 15 USDT on 0.01 BTC before fees and slippage: (50,000 − 48,500) × 0.01. That stop is 3,250 USDT above the estimated 45,250 liquidation level. If your account is 750 USDT, the planned 15 USDT price loss equals 2% of the account—not 2% of the position’s 50 USDT margin. A stop order can still fill at a worse price during a fast move or fail to close as expected. (mexc.com)

How Algentis uses this

Algentis trades MEXC USDT perpetual futures and requires a structure-based stop-loss on its signals. It also caps concurrent positions and has a daily-loss circuit breaker; those rules manage exposure, but they do not remove liquidation or execution risk.
