Liquidation Price Calculator

How to use this liquidation price calculator

First pick the direction: a long bets on a rise and gets cut if price falls to the liquidation price; a short bets on a drop and gets cut if price climbs to it. Then enter the entry price (roughly where you got in), the leverage, and finally that "maintenance margin rate" — a ratio Binance sets by position size, usually very low for small positions. The default of 0.5% is a conservative approximation; the real number is in Binance Futures' "margin rate" table, and the bigger the position, the higher this ratio. Once filled, the right side shows the liquidation price directly, and the buffer bar below shows what percentage of cushion remains between entry and the liquidation price: the longer the bar, the safer; the shorter, the more dangerous.

Drag the leverage field and feel it: at 10x the buffer is roughly a bit over 9%; bump it to 50x and the buffer instantly shrinks to under 2% — meaning a 2% adverse move and you're gone. That's exactly why a beginner should slide the leverage around here first, instead of jumping straight to 100x.

How the liquidation price is calculated

The principle: the maximum adverse loss your margin can withstand equals the bit of capital you put in at entry, minus the "maintenance margin" the platform requires you to keep at all times. The higher the leverage, the smaller your capital is as a share of the position (10x means 1/10), so the swing it can withstand is naturally smaller. For a long, liquidation price ≈ entry × (1 − 1/leverage + maintenance margin rate); a short is the reverse. Binance actually triggers liquidation off the mark price (not the last traded price), and layers in funding, fees and more, so the real liquidation price is usually a bit closer to entry than this simplified value.
