Liquidation calculator.
Know your liquidation price and safety buffer before you hit “buy”. Long and short, leverage up to ×125.

Approximate isolated-margin formula (MMR 0.5%). The exact level depends on the exchange, position tier and fees. Prices are live market data.
The calculator does the math. It cannot see the market.
Liquidation price, position size, stop distance — that is arithmetic. Whether price actually reaches your stop, what funding is doing, which way open interest leans and where other traders’ liquidations are stacked — that is analysis. Moami’s team of AI analysts examines your position against live market data and returns scenario probabilities, not opinions.

How the liquidation price is calculated
Liquidation happens when the position’s loss eats almost all of its margin, leaving only the maintenance margin. For isolated margin on USDT perpetuals the approximation is:
Here L is leverage and MMR is the maintenance margin rate (typically 0.4–1% for the lowest tiers). The key takeaway: your liquidation buffer ≈ 1/L. At ×10 leverage that is about 10%, at ×50 — under 2%, at ×100 — under 1%. At those levels it is not “the market moving against you” that closes the position, it is ordinary intraday noise.
Clusters of other traders’ liquidations themselves become a magnet for price — large players can see where they can be harvested. We break down how to read this in our liquidation map article.
FAQ
How is the liquidation price calculated?
For isolated margin on USDT perpetuals the approximation is: long — entry × (1 − 1/leverage + MMR), short — entry × (1 + 1/leverage − MMR), where MMR is the maintenance margin rate (0.5% in this calculator). The higher the leverage, the closer liquidation sits to your entry.
Why does my exchange show a slightly different liquidation price?
Exchanges account for position tiers (MMR grows with size), closing fees and margin mode (cross vs isolated). This calculator gives a conservative isolated-margin approximation — the real level is usually within a fraction of a percent.
What liquidation buffer is considered safe?
There is no hard standard, but BTC daily volatility is typically 3–5%, and higher for altcoins. If your buffer is smaller than a normal daily move, ordinary noise can wipe the position without any trend. Leverage of ×50 and above leaves less than a 2% buffer.
Is it free? Do I need to sign up?
Yes — the calculator is completely free and requires no registration. The math runs in your browser; the numbers you enter are not sent anywhere.
How is this different from an AI position analysis?
The calculator is a formula: it shows where liquidation sits. Moami’s AI analysis estimates how likely price is to get there: funding, open interest, clusters of other traders’ liquidations, the technical picture. Your first analysis is free after signup.
