How to Calculate Your Crypto Liquidation Price (Before It Calculates You)
I've been liquidated. More than once. The first time was insane. I took a 10x short margin position against BTC/USD on Bitfinex below $9K and got liquidated around $56K. One minute you have a position, the next you have a notification and zero balance. I still remember that feeling.
That was back when most altcoin pairs only traded against BTC and leverage was something you had to really dig for (OG RU here? :). Things have changed. Margin trading as a start point, perpetual futures then. Leverage is one tap away, and liquidations happen every single day to traders who opened a position without knowing exactly where the exchange would close it. Just remember October 2025 and 6th February 2026.
So let's fix that. I have some thoughts to share.
What is the liquidation price?
When you trade on leverage, the exchange literally lends you money. It is much easier to get a trading loan than to cover it, believe me. If your position moves against you enough that your collateral can no longer cover the loss - the exchange closes your position automatically. That price point is your liquidation price.
It's not random. It's calculated. And you can know it before you open the trade.
The basic formula
For a long position:
Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance Margin Rate)For a short:
Liquidation Price = Entry Price × (1 + 1/Leverage - Maintenance Margin Rate)Maintenance margin varies by exchange - Binance as a main perps player, uses around 0.5% for BTC, Bybit is similar. It doesn't sound like much but it shifts your liquidation price more than you'd expect at high leverage.
Example:
- BTC long at $80,000
- 10x leverage
- Binance maintenance margin 0.5%
Liquidation = 80,000 × (1 - 1/10 + 0.005) = 80,000 × 0.905 = $72,400Your position gets liquidated if BTC drops to $72,400. That's a 9.5% move — not a lot in crypto.
Why the formula alone isn't enough
Here's what most liquidation calculators don't tell you: the real liquidation price depends on your exact margin balance, not just leverage.
If you add more margin to a losing position, your liquidation price shifts. If you're using cross margin instead of isolated, your entire account balance becomes your margin - which protects you longer but puts more capital at risk. I prefer cross margin where you're able to hedge by holding the underlying perp asset, but that's up to you.
And then there are fees. Opening a position costs you taker fees (typically 0.04-0.06% on major exchanges). VIP tiers can give a distinct fee discount - I advise you to check the conditions for better tiers. That's not huge, but it means your break-even and your effective liquidation are slightly worse than the clean formula suggests.
Just use a calculator
Honestly, doing this math in your head before every trade is how mistakes happen. In my life I'm a product guy, working with blockchain products and I know the crypto space pretty well. I built a calculator that handles all of this — entry price, leverage, margin mode, and exchange-specific maintenance margin rates for Binance, Bybit, and OKX.

What to do with this number
Once you know your liquidation price, compare it to:
- Recent support levels - if liquidation sits right at a major support, the exchange might take you out right before the bounce
- Your stop loss - your stop should always be above (long) or below (short) your liquidation price, never below it
- Realistic volatility - if BTC moves 8% routinely and your liquidation is 9% away, you're one bad day from zero
The goal isn't to avoid ever losing. It's to stay in control of when and how much you lose. Knowing the outcome is much better than not knowing.
