About ProLiq Calc

What We Built

ProLiq Calc started from a simple problem: existing liquidation calculators were either cluttered with ads, required sign-ups, or only supported a single exchange. We wanted something fast, clean, and actually useful — a tool you could open, plug in your numbers, and get an answer in seconds.

The calculator covers the four largest derivatives exchanges — Binance, Bybit, OKX, and Bitget — with accurate maintenance margin rate data, cross-exchange comparisons, and a funding rate drag estimator. No registration, no email, no downloads. Everything runs in your browser.

Who It's For

This tool is built for anyone trading perpetual contracts who wants to understand their risk before entering a position. Whether you're a beginner learning how leverage works or an experienced trader comparing liquidation prices across exchanges, the calculator gives you the numbers you need to make informed decisions.

How It Works

Our calculator uses each exchange's published maintenance margin rate (MMR) tiers to estimate your liquidation price. We pull real-time price data from CoinGecko so you're always working with current market prices. The reverse calculator lets you work backwards — set a price you consider safe, and we'll tell you the maximum leverage you can use without getting liquidated before that point.

The funding rate drag calculator helps you understand the cost of holding a leveraged position over time, factoring in the periodic funding payments that perpetual contract traders pay or receive.

Our Approach to Privacy

We believe a calculator shouldn't need your personal data. ProLiq Calc doesn't require registration, doesn't use analytics trackers, and doesn't store any information about your usage. The only data processed is what you type into the calculator, and that stays in your browser. You can read more in our Privacy Policy.

Transparency

We're upfront about how this site is supported. ProLiq Calc contains affiliate links to the exchanges we link to. If you sign up through one of those links, we may earn a commission at no extra cost to you. This doesn't affect our calculations or the information we present — the math is the math regardless of how you open an account. Full details are in our Disclaimer.
