Crypto Margin Calculator

The capital you must post to open a leveraged position: notional value divided by leverage. A $30,000 position at 10× needs $3,000 of initial margin. It is not a fee — it is your money, held as collateral.

The minimum equity the position must retain to stay open, quoted as a percentage of notional value — typically 0.4–0.5% for BTC at modest size. Once your margin falls to this level the exchange issues a margin call or liquidates the position outright.

Maintenance margin divided by your available margin, as a percentage. At 100% you are liquidated. Most traders treat anything above 50–60% as a position that needs reducing rather than watching.

A margin call is a request to add collateral or reduce the position before it is closed for you. Crypto perpetuals often skip it entirely — the engine liquidates automatically at the maintenance threshold, because prices move faster than anyone can respond.

It works from the collateral side rather than the price side: how much margin the position ties up, how much of it is already committed to the maintenance requirement, and what headroom is left. The margin call price falls out of that, and should agree closely with a liquidation calculator using the same maintenance rate.

Risk-limit tiers. The maintenance margin rate rises with position size, so a large position carries a higher rate than the one you may have entered. Exchanges also add a liquidation fee and deduct accrued funding, both of which pull the real trigger price closer.
