Liquidation price estimator

In isolated margin, how far does price have to move against you before you are closed out? Four numbers gives you the answer — and shows how sharply that distance shrinks as leverage goes up.

Entry price Your actual average fill

Leverage 1 to 200

Maintenance margin rate % Copy it from the platform's tier table, do not guess

Position quantity (optional) Needed only for the margin amounts

This is an estimate, not the platform's number The formula is the standard isolated-margin, linear-contract derivation. It does not account for trading fees, accrued funding payments, or the maintenance margin rate changing as a position crosses size tiers. All three make real liquidation arrive earlier than this figure suggests. The number on your own trading screen is the one that counts.

How to use this, and how to read the output (expand)

What it is for

Plenty of people open a position thinking "I can handle a 10% drawdown" without ever having checked whether that is true. This translates a leverage multiple into a concrete price: reach this, and the position is gone. Seeing the actual number tends to make people's relationship with leverage considerably more realistic.

Filling it in

Entry price is your real average fill. If you added to the position, use the weighted average, not the first fill.
Leverage is the multiple you actually used.
Maintenance margin rate has to come from the platform's tier table. It steps up with position size and differs between contracts. Do not fill this from memory — get it wrong and the output is meaningless.
Position quantity is optional. Adding it computes your initial margin so you can check the figure against your account.

What the output rows mean

Estimated liquidation price — where margin is consumed down to the maintenance line.
Tolerance — the distance from entry to that price, as a percentage. This is the number worth looking at; it tells you directly how much of a retrace the position survives.
Initial margin — position value divided by leverage, i.e. what you locked into the position.
Position value — entry price times quantity, the notional size. Funding is charged on this figure, not on your margin.

Why real liquidation usually comes sooner

Three reasons. Fees: charged at entry, so your margin starts lower than the theoretical value. Funding: deducted every settlement interval you hold, so the longer you hold the further the liquidation price drifts against you. Tier crossings: a larger position moves into a stricter maintenance requirement, moving the liquidation price with it.

And one factor that is not arithmetic at all: liquidation is normally evaluated against the mark price, not the last traded price, so the number you watch and the number that closes you may differ. Full mechanism: how your liquidation price is derived.

Where the data comes from

This page fetches no market data and connects to no trading account and contains no live prices. Every number comes from what you type, the arithmetic happens in your browser, and nothing is sent anywhere. The default values are there so the page has something to show on load — they are an example, not a market.

What to do with the answer

If the tolerance looks too thin, the correct response is less leverage, not a better argument for why it is fine. Reducing leverage is the only lever that directly and reliably widens that distance. And while a position is open, come back and recalculate periodically — funding is quietly moving the number.
