Liquidation is the single most feared event for any futures trader. On Bybit, it happens when your position margin drops to zero because the market moved against you. But it’s not random — there’s a clear formula behind it. Understanding that formula could save your account from getting wiped out. Let’s break down exactly how Bybit calculates liquidation price, step by step.
At a Glance
| # | Key Point | Why It Matters |
|---|---|---|
| 1 | Liquidation price depends on leverage, entry price, and margin mode | Higher leverage pushes liquidation closer to your entry |
| 2 | Isolated margin protects your whole balance from a single bad trade | Your other funds stay safe if one position liquidates |
| 3 | Cross margin uses your entire wallet balance as buffer | One losing trade can drain your whole account |
| 4 | Maintenance margin is the minimum collateral required to keep a position open | Once equity falls below this level, liquidation triggers |
| 5 | Bybit uses mark price, not last price, for liquidation checks | Prevents fakeouts from sudden wicks on the order book |
| 6 | Long and short positions have different liquidation formulas | Know both to manage risk on either side |
| 7 | Adding margin manually can lower your liquidation price | Gives you breathing room without closing the trade |
| 8 | Position size and contract type (USDT vs. inverse) affect the math | Inverse contracts use coin value, not dollar value |
1. Leverage Is the Biggest Factor in Liquidation Distance
Leverage is a double-edged sword. On Bybit, you can choose from 1x up to 100x leverage on most contracts. The more leverage you use, the less room the market has to move against you before liquidation. Here’s a concrete example: if you open a $100 long position on BTC/USDT with 10x leverage, your margin is $10. A 10% drop in BTC price wipes out that $10, triggering liquidation. But with 5x leverage, your margin is $20, and you can withstand a 20% move before liquidation kicks in. So leverage directly determines your liquidation distance. Investopedia explains that margin requirements scale inversely with leverage — higher leverage means higher risk of losing everything.
2. Isolated Margin Keeps Your Losses Contained
Bybit gives you two margin modes: isolated and cross. In isolated mode, you allocate a specific amount of margin to one position. If that position gets liquidated, you only lose the margin you put in — not the rest of your wallet balance. This is a risk-managed approach for traders who want to cap downside on each trade. For example, if you have $500 in your wallet and put $50 into an isolated long, the worst that happens is you lose that $50. The remaining $450 stays untouched. Isolated margin is ideal for testing strategies or trading news events where volatility spikes.
3. Cross Margin Can Liquidate Your Entire Wallet
Cross margin is the opposite. Bybit uses your entire available wallet balance as collateral for all open positions. If you have $1,000 in your wallet and one position starts losing, the exchange pulls from the rest of your balance to keep it alive. But that means a single bad trade can drain your whole account. Cross margin can delay liquidation because there’s more buffer, but it also magnifies the damage if the market keeps moving against you. Most experienced traders use cross margin only when they’re actively monitoring positions. For beginners, isolated margin is generally the safer choice.
4. Maintenance Margin Is the Trigger Point
Every perpetual futures contract on Bybit has a maintenance margin rate (MMR). For BTC/USDT, the MMR is typically 0.5% of the position value. That means you need at least 0.5% of the contract’s notional value in your margin to keep the position open. If your margin falls below this level, liquidation triggers. Say you have a $10,000 BTC position with 20x leverage. Your initial margin is $500 (5% of $10,000). The maintenance margin is $50 (0.5% of $10,000). If the position loses $450 in value, your remaining margin hits $50 — and Bybit closes the position. The SEC notes that maintenance margins are set by exchanges to protect both traders and the platform from insolvency.
5. Bybit Uses Mark Price, Not Last Price
Here’s a key nuance: Bybit doesn’t check the last traded price when deciding to liquidate you. It uses the mark price, which is a fair value index based on the spot market. This prevents liquidations from brief, sharp wicks that don’t reflect the true market. For instance, if BTC suddenly drops $200 in one second but instantly recovers, the last price might flash below your liquidation level. But because mark price smooths out those spikes, your position stays open. This system also reduces the chance of getting “stop hunted” by large players. CoinDesk explains that mark price mechanisms are standard across major exchanges to ensure fair liquidation.
6. Long and Short Positions Have Different Formulas
Mathematically, liquidation price for longs and shorts is calculated differently. For a long position in USDT-margined contracts:
Liquidation Price (Long) = Entry Price × (1 – (Initial Margin – Maintenance Margin) / Position Value)
For a short position:
Liquidation Price (Short) = Entry Price × (1 + (Initial Margin – Maintenance Margin) / Position Value)
So if you buy BTC at $60,000 with 10x leverage, your liquidation price is roughly $54,000 for a long. If you short at the same price, liquidation is around $66,000. The formulas are symmetrical but reversed. Knowing these numbers before you enter a trade can help you set stop-losses that actually protect your capital.
7. Adding Margin Lowers Your Liquidation Price
If a trade goes against you and your liquidation price gets dangerously close, Bybit lets you add more margin in isolated mode. This pushes the liquidation price further away, giving the trade more room to recover. For example, if your long position has a liquidation price of $55,000 and BTC is at $56,000, adding $50 of margin might move your liquidation down to $53,500. But this isn’t a guaranteed fix — the market could keep falling. Adding margin is a risk-aware tactic, not a guarantee of survival. Only add margin if you have a clear reason to believe the move is temporary.
8. Position Size and Contract Type Change the Math
Bybit offers two contract types: USDT-margined (linear) and coin-margined (inverse). For linear contracts, the liquidation price uses the entry price and leverage directly. For inverse contracts, the calculation involves the contract quantity in coins and the current exchange rate. For example, a 1 BTC inverse contract opened at $60,000 with 10x leverage has a different liquidation price than a USDT contract of the same value. The key difference is that inverse contracts use the coin as collateral, so the liquidation price depends on both the trade direction and the USD value of the coin. Always check the liquidation price in the order confirmation box before you open a position.
Risks and Pitfalls to Watch For
Liquidation is not the only danger. Here are three common mistakes traders make on Bybit:
- Overleveraging with cross margin: Using 50x or 100x leverage in cross margin can lead to a total account wipeout from a small 2% move. Always use isolated margin unless you know exactly what you’re doing.
- Ignoring funding rates: On Bybit, funding fees are paid every 8 hours. If a position stays open for days, these fees can eat into your margin and push you closer to liquidation without the price moving at all.
- Not setting a stop-loss: Many traders rely on the liquidation price as their only safety net. But liquidation happens at the worst possible moment — when volatility is highest. A manual stop-loss at a safer distance can save you from getting liquidated at a terrible fill price.

The One Thing to Remember
Your liquidation price is not a mystery — it’s a simple calculation based on your entry price, leverage, and margin mode. Before you open any futures position on Bybit, calculate the liquidation price manually or use the exchange’s built-in calculator. If that price is too close to the current market, reduce your leverage or use a smaller position size. That one habit can prevent 90% of liquidation disasters.
