What is the liquidation price in Binance Futures? How to calculate it.

Liquidation Price Definition

1. Liquidation price is the market price at which a leveraged futures position is automatically closed by the exchange to prevent further losses.

2. It represents the threshold where the margin balance falls below the maintenance margin requirement.

3. Binance Futures triggers liquidation when the position’s unrealized PnL reduces equity to the point that it no longer satisfies the minimum margin ratio.

4. This mechanism protects both the trader and the insurance fund from insolvency during extreme price movements.

5. Liquidation is not a fee-based event but an enforced risk control action executed by the matching engine in real time.

Key Variables in Liquidation Price Calculation

1. Initial margin is derived from the position size divided by the selected leverage level.

2. Maintenance margin varies by asset, contract type (USDT-margined or COIN-margined), and position size — Binance publishes tiered maintenance margin rates.

3. Entry price determines directional sensitivity: long positions liquidate below entry, short positions above it.

4. Position size is measured in contracts or notional value depending on the interface view selected.

5. Funding rate accruals are excluded from liquidation price computation — only mark price, position size, and margin parameters matter.

Formula for USDT-Margined Contracts

1. For a long position: Liquidation Price = Entry Price × (1 − Initial Margin Rate + Maintenance Margin Rate) / (1 − Maintenance Margin Rate).

2. For a short position: Liquidation Price = Entry Price × (1 + Initial Margin Rate − Maintenance Margin Rate) / (1 + Maintenance Margin Rate).

3. Initial Margin Rate equals 1 / leverage — e.g., 20x leverage → 5% initial margin.

4. Maintenance Margin Rate is dynamic — for BTC/USDT perpetual up to 125x, it starts at 0.4% for positions under 200 BTC and increases in tiers.

5. Binance uses the mark price — not last traded price — to determine liquidation, reducing manipulation risk.

Real-Time Monitoring Tools on Binance

1. The position panel displays live liquidation price next to “Liq. Price” in bold red text for active positions.

2. A visual liquidation bar appears beneath the order book showing distance to liquidation in percentage terms.

3. Users can enable “Liquidation Price Alerts” in settings to receive notifications when price approaches critical thresholds.

4. The “Risk Limit” selector allows traders to adjust position tiers, directly influencing maintenance margin and recalculating liquidation price instantly.

5. Historical liquidation events are logged in the “Position History” tab with timestamps and executed mark prices.

Frequently Asked Questions

Q: Does leverage change the liquidation price after opening a position?A: No. Leverage is fixed at order execution. Changing leverage post-entry is not possible; only closing and reopening adjusts exposure.

Q: Why does my liquidation price shift without me placing new orders?A: Mark price updates, funding rate settlements, and changes in maintenance margin tiers due to position size expansion can cause recalculations.

Q: Can partial liquidation occur in Binance Futures?A: No. Binance performs full liquidation of the entire position. Partial closures must be manually initiated by the user via reduce-only orders.

Q: Is insurance fund coverage applied before or after liquidation?A: The insurance fund absorbs losses only after liquidation is completed and the bankruptcy price is determined — it does not prevent liquidation itself.
