How the Liquidation Price Is Calculated
For a linear (USDT-margined) perpetual on isolated margin, the liquidation price is the mark price at which your remaining equity equals the maintenance margin requirement. The simplified textbook formula — used by Binance, Bybit, and OKX in their public help docs — is:
Reading the formula: liquidation distance scales as roughly 1/Leverage − MMR. At 10× leverage with 0.5% MMR, a long liquidates ~9.5% below entry. At 50× the same long liquidates ~1.5% below entry. Doubling leverage roughly halves your liquidation buffer.
Worked Example
Open a 10× long on BTC at $67,450, $10,000 notional, 0.5% MMR:
- Initial margin = $10,000 / 10 = $1,000
- Maintenance margin = $10,000 × 0.005 = $50
- LiqPrice = $67,450 × (1 − 0.10 + 0.005) = $61,103.62
- Distance from entry = −9.41%
BTC needs to drop just under 9.5% before this position is force-closed. Add fees and funding and the real liquidation will trigger a few basis points earlier.
Risk warning
Leveraged perpetual trading can result in the total loss of deposited margin within minutes. Liquidation engines use the mark price (not your exchange's last trade), and mark prices can wick on thin liquidity. Size positions so that a 2× to 3× safety buffer beyond the calculated liquidation price is comfortably affordable.

Frequently asked questions
How is the liquidation price calculated?
For an isolated-margin linear perpetual, liquidation price = entry × (1 − 1/leverage + MMR) for longs and entry × (1 + 1/leverage − MMR) for shorts, where MMR is the maintenance margin rate. This is the formula published by Binance, Bybit, and OKX in their official help docs and excludes fees, funding, and unrealized PnL adjustments.
Why does my exchange show a slightly different liquidation price?
Real exchanges include trading fees, accrued funding, and (for cross-margin) the wallet balance into the calculation. They also use tier-based MMR that climbs as your position size grows. This calculator uses the textbook isolated-margin formula at the MMR you select — treat the result as a clean upper-bound estimate, not the live exchange engine value.
What maintenance margin rate (MMR) should I use?
Most major venues use 0.4–0.5% MMR for the smallest size tier on BTC and ETH perps. Tier MMR rises with notional — at $5M+ exposure on BTC it can climb to 1–2.5%. If you don't know your tier, 0.5% is a safe default for retail-sized positions on BTC/ETH.
Does higher leverage always mean a closer liquidation price?
Yes. Liquidation distance scales as ~ (1/leverage − MMR). At 10× with 0.5% MMR a long liquidates ~9.5% below entry; at 50× the same long liquidates ~1.5% below entry. Doubling leverage roughly halves your liquidation buffer — a key reason high-leverage positions get wiped out by routine intraday wicks.
How does cross margin change the liquidation price?
Cross margin pools your entire wallet balance against the position, so the effective liquidation price is much further away than the isolated-margin number — but a single bad position can drain the whole wallet. This calculator models the isolated case, which is the conservative way to size risk.
Should I add fees and funding to the formula?
For a quick sanity check, no — the basic formula is fine. For a position you intend to hold for days or weeks, subtract expected funding payments from your effective margin: each funding interval shifts the liquidation price slightly closer. Fees on entry and forced liquidation also widen the gap by 0.05–0.10% per side at most major venues.
