Liquidation mechanics on Bybit
This calculator's formula models isolated margin: the standard way to size a single position's liquidation risk on its own. If your account runs cross margin instead, your real liquidation price also depends on your other positions and total account balance, not just this one. On Bybit itself, new positions default to Cross Margin at 10× leverage under One-Way mode - margin mode is account-wide, not set per symbol.
When your equity falls below the maintenance margin requirement, Bybit runs a laddered process - first cancelling orders that would grow the position, then attempting a partial close sized to drop into the next-lower risk-limit tier, and finally moving to full liquidation at the bankruptcy price if that still isn’t enough.
On Bybit, maintenance margin for BTCUSDT is 0.5% up to 2,000,000 USDT position value, stepping up to 0.56% above 2,600,000 USDT - it rises in tiers as your position grows, not a flat rate. The formula below simplifies this to a flat 0.5% for readability: for a long position, liquidation price ≈ entryPrice × (1 − 1/leverage) / (1 − 0.005). At 100× maximum leverage this means even a tiny adverse move can trigger liquidation, which is why most experienced traders use 5–20× rather than the maximum.
Bybit's auto-deleveraging (ADL) system only kicks in if the insurance fund can't cover a bankrupt position; it ranks positions by leveraged return - the highest leveraged-return accounts on the opposite side get deleveraged first. In practice, staying well above your liquidation price eliminates ADL risk entirely.
Bybit fee structure
Bybit charges maker fee 0.01% and taker fee 0.06% on perpetual futures. Maximum available leverage is 100×. This calculator pre-fills these defaults so you get accurate results without needing to look up the fee schedule. If you are on a VIP tier with discounted fees, adjust the fee fields accordingly.
Maker orders (limit orders that add liquidity) cost less than taker orders (market orders that remove liquidity). On Bybit, using limit orders for both entry and exit can reduce your total fee cost significantly compared to market orders.
Margin mode: new positions default to Cross Margin at 10× leverage under One-Way mode - margin mode is account-wide, not set per symbol. See Bybit's official docs →

View API & MCP docs →How is liquidation price calculated?
Liquidation price depends on your entry price, leverage and maintenance margin. For a long: liq ≈ entry × (1 − 1/leverage) / (1 − maintenanceMarginRate).
What happens when a position is liquidated?
The exchange forcibly closes your position when losses consume your margin. You lose the full margin used for that position.
What assumptions and edge cases does this calculator use?
Entry price and leverage must be above zero, the maintenance margin rate is a fraction from 0 to 0.2 (default 0.005), and a liquidation fee from 0 to 0.05 can be added. The flat rate is one rate you take from your exchange; for a tiered table give size and 1 to 50 tiers in ascending order, and a table that contradicts itself is refused. Not covered: auto-deleveraging, partial liquidation, mark price versus last price, funding paid while the position is open, and the exchange own engine, which may differ.
