How to Calculate Liquidation Price on Crypto Futures

Trading futures and scared of getting liquidated? Good. You should be. But fear without understanding the math won't save your deposit. What saves it is knowing the exact price at which the exchange will force-close your position — before you even open it.

This article covers the calculation formula, how the calculators on Binance and Bybit work, and which tools actually help you keep liquidation under control.

What Is a Liquidation Price

The liquidation price is the level at which the exchange force-closes your position. Not a stop-loss, not a margin call asking you to top up your account. A hard, automatic close — after which your entire margin goes to the exchange's insurance fund.

The mechanics are straightforward. You open a position with leverage and put up collateral (initial margin). While the position is in the red, the loss gets deducted from your margin. When the margin balance drops to the maintenance margin level, the exchange closes the position automatically. That price point is the liquidation price.

Maintenance margin is the minimum collateral that must remain on the position. The moment your actual margin balance hits that level, the exchange liquidates. On Binance for BTC/USDT with a position under 50 BTC, it's 0.5%.

Why does the math matter here specifically? Because the "gut feeling" of being safely far from liquidation is almost always wrong. A trader opens a BTC long with 20x leverage, thinks "still plenty of room before liquidation," and then price drops 4.7%. Position liquidated. At 20x leverage, a 5% move against you is enough.

Liquidation Price Formula

Different exchanges use slightly different algorithms, but the core logic is the same everywhere.

Isolated Margin

With isolated margin, a fixed amount is locked on the position. That's the most you can lose.

For a long:

Liquidation Price = Entry Price × (1 - Initial Margin % + Maintenance Margin %)

For a short:

Liquidation Price = Entry Price × (1 + Initial Margin % - Maintenance Margin %)

Where Initial Margin % = 1 / leverage.

Let's walk through a real example. We open a BTC/USDT long at 67,000, 10x leverage, maintenance margin on Binance for this pair is 0.5% (0.005).

Initial Margin = 1 / 10 = 0.1 (10%)

Liquidation Price = 67,000 × (1 - 0.1 + 0.005) = 67,000 × 0.905 = 60,635

Result: liquidation at ~60,635 USDT. That's roughly 9.5% below entry.

Same example at 20x leverage. Initial Margin = 1 / 20 = 0.05 (5%).

Liquidation Price = 67,000 × (1 - 0.05 + 0.005) = 67,000 × 0.955 = 63,985

Now you're ~4.5% from liquidation. At normal BTC volatility, that disappears in minutes.

Cross Margin

With cross margin, your entire free account balance goes into the calculation. Liquidation will happen at a lower price, but if it does happen — you lose the whole account, not just the amount allocated to the position. That's not protection, it's a different kind of risk.

The cross margin formula is more complex because it accounts for all positions simultaneously. Exchange calculators handle this automatically, but the underlying principle is the same: liquidation price is the point where the combined loss across all positions equals the total balance minus maintenance margin.

Table: Leverage and Distance to Liquidation

At 100x leverage, half a percent of movement is enough. On BTC, that's a few minutes of normal trading.

Liquidation Calculator: Binance and Bybit

Both exchanges have built calculators directly into the interface. Same logic, different UI.

Binance

The Binance liquidation calculator is in the futures trading interface, inside the order entry panel (calculator icon next to the price field). Two modes.

The first mode (PnL) calculates profit and loss at a given close price. The second mode (liquidation) shows the force-close price based on position size, entry price, and margin amount.

Step by step on Binance:

• Select margin type (isolated / cross) • Enter direction (long / short) • Enter entry price and leverage • Enter the number of coins or volume in USDT • The calculator shows the liquidation price

One thing to keep in mind: Binance factors in maintenance margin, which depends on position size. For positions under 50 BTC it's 0.5%, for positions above 50 BTC the rate is higher. At larger volumes the liquidation price shifts closer to entry.

The Binance liquidation calculator (in the standard interface) only covers isolated margin properly. For cross margin it gives an approximate figure that doesn't account for other open positions.

Bybit

On Bybit, a similar calculator is available via the "TP/SL" button or through the separate "Calculator" section in the menu. The interface is slightly cleaner — it immediately shows the margin required for the position and the distance to liquidation in percentage terms.

The key difference with Bybit: the exchange uses "partial liquidation" for large positions. Instead of an immediate full close, it first reduces the position size and leverage, giving the trader a chance to keep part of it. This changes the actual full liquidation price compared to what the calculator displays.

Manual Calculation Using the Formula

Universal formula for an isolated long:

Liquidation Price = Entry Price × (1 - (1/Leverage) + Maintenance Margin Rate)

For a short:

Liquidation Price = Entry Price × (1 + (1/Leverage) - Maintenance Margin Rate)

In practice, the maintenance margin rate for top pairs (BTC, ETH) on major exchanges falls in the 0.4–0.5% range. For low-liquidity altcoins it can reach 2–5%, which shifts liquidation meaningfully closer to the entry price.

How to Push Liquidation Further Away

There are three main ways to increase the distance between your entry price and liquidation.

Reduce Leverage

The most obvious and most effective. Going from 20x to 10x doubles the distance to liquidation. But lower leverage means lower returns when price moves in your favor. There's no right answer here — just a tradeoff between risk and reward.

I typically work with 5–10x leverage on BTC and ETH and don't go above 20x even on setups I feel confident about. Above 20x isn't trading anymore — it's a lottery.

Add Margin

With isolated margin, you can manually add funds to the position, increasing the collateral. This pushes the liquidation price further from the current price.

Example: opened a BTC long for 1,000 USDT at 10x leverage at 67,000, liquidation at 60,635. Added another 500 USDT to the margin.

New position: volume 10,000 USDT (unchanged), margin is now 1,500 USDT. With 1,500 USDT margin on a 10,000 USDT position, the effective leverage becomes ~6.67x. Liquidation price:

67,000 × (1 - 0.15 + 0.005) = 67,000 × 0.855 ≈ 57,285

Distance to liquidation went from 9.5% to ~14.5%. But this only works if you add margin proactively — not when the position is already running against you.

Use a Stop-Loss Above the Liquidation Level

This doesn't push liquidation further mathematically, but it protects you from it practically. A stop-loss above the liquidation level ensures the exchange doesn't get there before you do.

Standard practice: place the stop no closer than 50% of the distance to liquidation. Liquidation at 60,635, entry at 67,000 — stop goes no lower than 63,800 (roughly halfway between entry and liquidation).

Factor in the Liquidation Heatmap

The liquidation heatmap shows zones where the largest volume of other traders' positions are set to be liquidated. Price often moves toward these zones precisely because there's volume there to fill large orders.

If your liquidation sits right in one of these zones, the probability of price reaching it is much higher than in a neutral area. The prominent "hot" zones on a liquidation heatmap get swept 80–90% of the time. Parking your liquidation right there is almost a guaranteed wipeout.

For more on how to work with the heatmap, see the article "Futures Liquidation: Mechanics and Liquidation Map".

Trade Example: Calculating Before Entry

Here's what this looks like in practice. ETH/USDT, entry price 3,450 USDT, 10x leverage, isolated margin 345 USDT (10%).

Maintenance margin for ETH on Binance: 0.5%.

Long liquidation price = 3,450 × (1 - 0.1 + 0.005) = 3,450 × 0.905 = 3,122

Distance to liquidation: ~9.5%. I set the stop at 3,320 (roughly 3.8% from entry). That creates a buffer: between my stop and liquidation there's still ~6% of price movement left. Take-profit at 3,620, risk/reward 1:2. Trade opened at 14:30, stopped out 40 minutes later at 3,320.

Result: minus 130 USDT (38% of margin). Painful, but not a zeroed account.

From experience: when you calculate liquidation before entering, it's psychologically easier to hold the stop. You're looking at real numbers — not just a feeling that "liquidation is still far away."

Common Mistakes When Calculating Liquidation

Ignoring maintenance margin. A lot of traders calculate liquidation as simply "1 / leverage" from the entry price. That gives you an inaccurate number. At 10x leverage, the "intuitive" liquidation is exactly 10% down, but the real one is 9.5% because of the 0.5% maintenance margin. For scalping this doesn't matter much — for tight-stop positions it does.

Not checking the maintenance margin for the specific pair. It's different for BTC, ETH, and altcoins. You open a SOL position at 20x thinking you've got 4.5% before liquidation — but the maintenance margin is 1%, so the real distance is 4%.

Adding margin when it's already too late. Adding margin only works preventively. When price has already traveled 80% of the way to liquidation, adding funds won't help — it just extends the pain and increases the final loss.

Confusing cross and isolated margin. You calculated liquidation for isolated, but opened the position with cross. Under cross margin the liquidation will shift, but if your other positions are also in the red, it may land closer than you expected.

Ignoring funding rate when holding a position. The funding rate doesn't directly change the calculated liquidation price, but every payment reduces your actual margin balance. At 0.1% every 8 hours, over three days roughly 0.9% of the position volume gets deducted. At 20x leverage that's already 18% of the initial margin — and liquidation effectively creeps closer even if price hasn't moved against you.

Secret Terminal: Real-Time Liquidation Control

Standard exchange interfaces don't show you the full picture. The Binance liquidation calculator gives you your number — but won't show you where price is heading or why.

Secret Terminal is a scalping terminal that brings together the order book, tape (time & sales), and density map in a single interface. When trading futures, that matters: seeing real limit order volume around potential liquidation levels.

The terminal also aggregates funding rate data from Binance, Bybit, OKX, MEXC, and WhiteBIT in real time. A positive funding rate on an open long means per-hour deductions from the position — gradual, easy to miss, slowly eating your margin and pulling liquidation closer. Having that visible right in the trading interface, without tab-switching, saves both nerves and money.

The terminal is free, supports Windows and macOS, connects via exchange API keys. Data is stored locally.

FAQ

• How do I calculate liquidation price manually?

  Formula for an isolated long: entry price multiplied by (1 minus one divided by leverage, plus maintenance margin as a decimal). At an entry price of 67,000, 10x leverage, and 0.5% maintenance margin: 67,000 × (1 - 0.1 + 0.005) = 60,635. For a short, the signs flip: entry price multiplied by (1 plus one divided by leverage, minus maintenance margin).

• How do I use the Binance liquidation calculator?

  The Binance liquidation calculator is in the futures trading interface — the calculator icon next to the price field. Select your margin type, direction, enter entry price, leverage, and volume. The calculator shows the liquidation price. For cross margin the result is approximate and doesn't account for other open positions on the account.

• What is maintenance margin and where do I find it?

  Maintenance margin is the minimum collateral that must remain on the position. Once your actual margin balance hits this level, the exchange liquidates the position. On Binance for BTC/USDT with a position under 50 BTC, it's 0.5%. For altcoins and low-liquidity pairs it's higher — sometimes 2–5%. Current tables are on each pair's page under the "Risk" section.

• Does the funding rate affect the liquidation price?

  Technically no, practically yes. The funding rate doesn't change the calculated liquidation level shown in the exchange interface. But every payment reduces the actual margin balance. At 0.1% every 8 hours, over three days roughly 0.9% of the position volume gets deducted. At 20x leverage, that's already 18% of the initial margin. Liquidation effectively closes in, even if price hasn't moved against you.

• Can the liquidation price change after a position is opened?

  With isolated margin — only if you manually add or remove margin. With cross margin, the liquidation price changes constantly as the balance of other positions on the account shifts. Bybit has a partial liquidation mechanism: the exchange can reduce position size and update the calculated liquidation level for the remaining portion.

• Is there a "safe" leverage?

  There's no "safe" leverage without context. A 5x BTC trade with a properly placed stop is safer than 2x leverage on an illiquid altcoin with no stop at all. The principle is simple: the distance to liquidation must be noticeably greater than your stop-loss. If your stop and liquidation are at the same level, you're trading without protection.
