the short version

how to use this tool

type an entry, drag the leverage, pick a side. the number above is the price where the exchange force-closes you — computed with the venue's actual maintenance-margin brackets, not a flat 0.5% guess. no signup, no api key, nothing leaves your browser except the mark price you asked for.

how this number is computed

your leverage and Bybit's maintenance rate for your size set the room; lower the leverage to widen it.

this page models isolated margin: liq = entry × (1 − 1/leverage + mmr) for longs, entry × (1 + 1/leverage − mmr) for shorts. mmr comes from Bybit's bracket table for BTC, picked by your position's notional.

on cross margin the whole wallet is the buffer, so the real liq floats with your balance — treat this number as the closest the engine could reach you. estimate — exchanges compute exact liq from live margin; always double-check on your venue.

worked example: BTC long at 20x, $2,500 notional

you're long BTC at $84,053, 20x, $2,500 notional. Bybit charges 0.33% maintenance margin at that size: $84,053 × (1 − 1/20 + 0.0033) = $80,127.

that's $3,925 of room — 4.67%. a 2.4% day is normal for bitcoin — tight by perp standards, which is exactly how accounts end up at 50x on it. the widest measured day still ran 3.9%, and the range being small does not make the leverage small: 2.0% is the tightest stop that clears the coin's own noise, and at 50x a 2.4% move is the whole position. funding at the example rate costs $0.75 a day on this size, and on isolated margin it comes out of that same room.

Bybit's BTC margin brackets, in words

bigger positions pay a higher maintenance rate, which pulls the liq closer at the same leverage.

bybit's BTC table opens at 0.33% maintenance margin with 150x on offer, and that first step holds all the way to $300,000 notional. above it the rate steps to 0.50%, leverage caps at 100x, and that bracket runs to $2,000,000.

the bracket follows notional, so a winning position can grow into a higher one. this page stores Bybit's first 5 brackets for BTC and holds the last rate flat past them — check very large sizes on the venue itself.

bybit's book is deep enough that liqs clear in one print during normal hours, but it's also historically where the wickiest candles show up in thin weekend conditions — the 2021-era stop hunts were mostly bybit tape.

Bitcoin specifics

leave room for Bitcoin's normal wick, not its average day.

read more

bitcoin does both: a 2.4% typical day on 1.7% of minute-to-minute movement, 3.9% at its widest, and no pattern to which one gets you. $472M across 21372 forced closes in 7 days, none over 3% of it: attrition, not one event, split 55%/45% long/short.

a stop loss is not a liquidation plan

the wick through your liq is what kills you. the alert reaches you while you can still act.

read more

forced liquidations are market orders into the book that just moved against you, so the fill lands worse than the trigger. and leverage creeps: 5x becomes 10x after a win, and each time you double it the room more than halves.

a stop only triggers, and in a cascade it fills into the same wick as the engine. the alert fires earlier, while you can still close at a real price or add margin and push the liq away. free, no signup.

binance vs bybit vs hyperliquid vs okx for this coin

same position, different venue, different liq: the lower maintenance rate at your size is free room.

on BTC the first bracket is not the same trade on every venue: bybit runs 0.33% to $300,000 at 150x, hyperliquid 1.25% to $150,000,000 at 40x. bybit is the cheaper first bracket by 0.92% of entry on the same position.

faq

is this liquidation price exact?

no — it's the isolated-margin approximation with your venue's real mmr brackets: liq = entry × (1 − 1/leverage ± mmr). exchanges also deduct liquidation fees and use their own index price, so their number can differ by a few tenths of a percent. estimate — exchanges compute exact liq from live margin; always double-check on your venue.

what's the difference between isolated and cross margin here?

isolated margin risks only the position's collateral; cross margin risks the whole wallet. the formula on this page is the isolated estimate. on cross, your real liq floats with your wallet balance — the more spare balance you hold, the further away liquidation sits, and this page can't see your wallet.

why did my liquidation price move after i opened the position?

mmr brackets are chosen by notional. if your position's value crossed a bracket boundary — because price moved or because you added size — the maintenance rate changed, and the liq price moved with it. check your bracket after any size change.

i already have a stop loss — why do i need a liquidation alert?

a stop loss is a pre-committed exit; the alarm is the room you have left to decide. three things a stop can't do: in a cascade your stop fills as a market order into the wick — at 20x+ the exchange's liquidation engine can fill first, with the insurance-fund fee on top. it can't tell you a funding debit just moved your liq closer. and it can't watch the book at 3am. closing early at a real price — or adding margin to push the liq away — beats being force-closed, and both need the warning, not the trigger. keep the stop. arm the alarm so the exit stays your choice.

does the exchange liquidate at exactly this price?

the trigger uses the venue's mark/index price, not the last trade, and the forced exit is a market order — so the fill is usually worse than the trigger. treat the liq price as a cliff edge you never touch, not a price you'd actually get.

can i get an alert before price nears my liquidation price?

yes — that's the point of the site. under the number there's an alert gate: set the distance (e.g. scream at me if btc gets within 3% of my liq) and pick telegram, web push, or email. free tier is 2 active alerts, no card, no api keys.
