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.

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. The tool then calculates the maximum leverage you can use without being liquidated before the price reaches that level.

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.

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. We recommend using the calculator as a planning tool and always setting stop-loss orders.

Cross margin means your entire account margin balance backs each position. Isolated margin means only the margin you specifically allocate to that position is at risk. Our calculator works with both modes.
