Built by Traders

Created by someone who's been liquidated before and wished they'd understood the math first.

Our Mission

We built ProLiq Calc because every trader deserves to understand their liquidation price before opening a position. Most traders jump into leveraged futures without knowing exactly when they'll get liquidated. We believe that information should be free, instant, and available to everyone.

Who We Are

ProLiq Calc is built and maintained by a crypto trader and developer who's been trading perpetual contracts since 2020. After experiencing a preventable liquidation, we set out to build the tool we wish we'd had.

Supported Exchanges

Our calculator uses real maintenance margin rate data from the top cryptocurrency derivatives exchanges:

Binance — BTC/USDT, ETH/USDT and more
Bybit — BTC/USDT, ETH/USDT and more
OKX — BTC/USDT, ETH/USDT and more
Bitget — BTC/USDT, ETH/USDT and more

Technology

ProLiq Calc is built as a lightweight, single-page web application. It loads fast, works offline, and delivers instant results. No heavy frameworks, no unnecessary JavaScript — just the math you need.
