Binance Liquidation Price: Formulas and Examples
Understand Binance Futures liquidation estimates with isolated and cross-margin formulas, worked examples, maintenance tiers and model limitations.
Isolated Margin Liquidation Price Formula (Long & Short)
Step-by-Step Calculation
Define the trade
Long 1 BTC on BTCUSDT perpetuals at an entry price of $65,000 with 20x isolated leverage. Position notional = 1 × $65,000 = $65,000. Initial margin (IMR = 1/20 = 5%) = $3,250.
Look up the bracket parameters
On Binance's BTCUSDT tiered margin schedule, a $65,000 notional sits in the lowest bracket. Maintenance Margin Rate (MMR) = 0.40% = 0.004. Maintenance Amount (cum_b) for that bracket = 0 USDT. These values are published in the 'Leverage & Margin' table on the Binance Futures page for each symbol.
Apply the long liquidation formula
LP = (3,250 + 0 − 1 × 65,000) ÷ (1 × (0.004 − 1)) ≈ $61,998.
Cross-check with the approximation
The additive shortcut gives $62,010 instead of $61,998: a difference of about $12, even with A = 0. It uses entry notional for maintenance; the equation above uses mark notional. This is an approximation, not an exact exchange quote.
Adjust for fees, funding and added margin
Binance's displayed liquidation price excludes future funding payments and trading fees, which gradually pull the liq price closer to entry on a long that pays funding. Adding margin to an isolated position (Wallet Balance ↑) pushes the long liq price down; withdrawing margin pushes it up. Recalculate after every margin change.
Under these stated assumptions, the modeled trigger is about $61,998, a 4.62% decline from entry. The trigger is not a guaranteed execution price or an exact final loss; mark price, fees and the liquidation process matter.
Liquidation at 10x vs 50x vs 100x
| Leverage | Liq. Price (approx) | Distance to Liq. | Risk Level |
|---|---|---|---|
| 3x | ~$43,593 | ~32.93% | Moderate |
| 10x | ~$58,760 | ~9.6% | High |
| 20x | ~$62,010 | ~4.6% | High |
| 50x | ~$63,960 | ~1.6% | Very high |
| 100x | ~$64,610 | ~0.6% | Extreme |
| 125x | ~$64,740 | ~0.4% | Maximum |
In this table's additive example, 100x leaves about 0.6% between entry and the estimated trigger. This is a model result, not a measured frequency of market moves or a guaranteed final loss. The risk labels are qualitative comparisons within this example, not probabilities or a complete risk assessment.
BTCUSDT maintenance tiers — observed 2026-09-07

| 11 | 800,000,000 – 1,200,000,000 | 2x | 25.00% | 121,482,000 |
| 12 | 1,200,000,000 – 1,800,000,000 | 1x | 50.00% | 421,482,000 |
This tier summary is not a complete account calculation. Check the current contract's maintenance rate and maintenance deduction at the calculated mark-price notional. A larger maintenance requirement changes the threshold, but does not by itself establish when liquidation will occur; collateral and other positions also matter.
Using Binance's Calculator
Open the Futures order panel
On binance.com/en/futures/BTCUSDT (or your chosen pair), the calculator icon sits in the top-right of the order entry panel, next to the leverage selector. The same calculator is available in the mobile app under the position screen.
Pick the right tab
The calculator has three tabs: PnL (returns a profit/loss given entry, exit and size), Target Price (returns the exit price needed for a target ROE%), and Liquidation Price. They share inputs but solve for different unknowns — make sure you're on the Liquidation Price tab before reading the output.
Match the margin mode to your position
Use the actual margin mode and eligible collateral. For a one-way isolated position, use its assigned margin. For cross margin, other contracts' unrealized PnL and maintenance requirements also matter. Recalculate after changes to position size, collateral, settled costs or applicable tiers; neither mode makes the estimate permanently fixed.
Test margin top-ups before committing
On an isolated long, increasing the assigned margin in the calculator pushes the liq price further below entry; reducing it pulls liq price toward entry. This lets you size a margin add (e.g. 'how much USDT do I need to move liq from $58k to $55k?') before clicking Add Margin on the live position.
Remember what the number excludes
A current account estimate should reflect costs already settled into its balances. Future funding and execution costs remain uncertain. Fee rates and funding schedules depend on the contract and account; check the current terms and next settlement rather than assuming one fee or an eight-hour interval. A hypothetical calculator only knows the inputs supplied.
Tips to Avoid Liquidation on Binance
Assess position size, eligible collateral and potential loss together. A leverage setting alone does not establish that a position is suitable or safe.
Isolated margin assigns collateral to a position. Later margin additions increase the funds exposed. Check any separately enabled strategy or automatic funding feature and its rules; do not assume the initial margin is a permanent loss cap.
Compare stop and liquidation triggers on the same price reference: a long's adverse stop should be above its liquidation threshold, a short's below. Mark-price liquidation can precede a last-price stop. Price gaps, slippage and partial or failed fills remain possible; no fixed percentage buffer guarantees protection.
For the Futures metric used here, margin ratio is maintenance margin divided by margin balance; 100% is the liquidation threshold. A reading below 80% is only a buffer, not a guarantee. Price moves and account changes can consume it quickly; other account modes can use different metrics.
Always verify your liquidation price using Binance's built-in calculator or our free Liquidation Calculator before confirming any trade.

Derivatives & Leveraged Products — Important Risk Warning
Derivatives and leveraged products are complex and carry a high risk of rapid, substantial losses. Depending on the product and account rules, losses can exceed the initial margin or money committed. A stand-alone purchased option can lose its entire premium plus transaction costs; writing options, exercising into another position, or combining positions can create additional obligations. An uncovered call writer can face unlimited loss. Applicable legal protections can affect the loss boundary.
You should carefully consider whether you understand how derivatives work and whether you can afford to take the high risk of losing your money. This content is for educational purposes only and does not constitute financial advice, investment advice, or a recommendation to trade derivatives.
Legal availability and regulatory protections depend on the product, service, provider and jurisdiction. In the EU, check the applicable investment-services rules, including MiFID II where relevant, and any product restrictions. Before trading, verify with the relevant regulator whether the provider has the permissions required for the service and whether the product may be offered to you. A website being accessible, or a product appearing on this website, does not establish authorization or eligibility.
