Frequently Asked Questions

The liquidation price is the market price at which your leveraged position is automatically closed by the exchange because your margin balance falls below the required maintenance margin. In simple terms, it's the price point where your position gets forcibly closed and you lose your initial margin. This is why understanding your liquidation price before opening a leveraged position is critical.

Our calculator uses each exchange's published maintenance margin rate (MMR) formula. When you enter your entry price, leverage, and direction (long or short), the tool applies the exchange-specific MMR to calculate the price at which your margin would be depleted. The cross-exchange comparison shows how this price differs across Binance, Bybit, OKX, and Bitget for the same position parameters.

Each exchange sets its own maintenance margin rate tiers. While they follow similar structures, the base rates differ. For example, Binance BTC perpetual starts at 0.4% MMR, while Bybit starts at 0.5%. These differences scale with position size and leverage, so the same position can have meaningfully different liquidation prices depending on which exchange you use.

Instead of calculating your liquidation price from a given leverage, the Reverse Safe Calculator works backwards. You enter your entry price and a target price you consider your minimum — like a strong support level for a long position. The tool then calculates the maximum leverage you can use without being liquidated before the price reaches that level. It's a useful way to size positions based on your market analysis.

Perpetual contracts use a funding mechanism to keep the contract price anchored to the spot market. Typically every 8 hours, traders on the majority side pay a fee to traders on the minority side. If you're consistently on the paying side, this creates a slow but steady cost — the "drag" — that eats into your position's value over time. Our Funding Drag Calculator estimates this cost based on your position size, the current funding rate, and your expected holding period.

We use the publicly documented MMR tiers from each exchange and real-time price data from CoinGecko. However, several real-world factors can cause actual liquidation prices to differ from our estimates: slippage during volatile periods, exchange insurance fund mechanisms, MMR tier changes, and the exact timing of funding payments. We recommend using the calculator as a planning tool — a solid reference point for understanding your risk — and always setting stop-loss orders on your positions.

We currently support the four largest derivatives exchanges: Binance, Bybit, OKX, and Bitget. The calculator covers BTC/USDT, ETH/USDT, SOL/USDT, and XRP/USDT — the most traded perpetual contracts across these platforms. We're planning to add more exchanges and trading pairs based on user feedback.

Yes. The site is fully responsive and works on smartphones, tablets, laptops, and desktops. The layout adjusts automatically — on mobile, the liquidation price dashboard appears right below the calculator form so you can see your results without scrolling.

ProLiq Calc is free to use and supported through affiliate links to the exchanges we reference.
