For an over-collateralised loan of the kind most lending protocols issue. Loan-to-value is what you owe divided by what your collateral is worth, and liquidation happens when a falling collateral price pushes that ratio up to the protocol's threshold — you do not have to do anything for it to happen. The liquidation price is the level the collateral has to reach, which is the number worth writing down before you borrow rather than after. The last two cells show the two ways out of a tight position: post more collateral, or repay. Liquidation penalties, borrow interest accruing on the debt, oracle price lag and multi-asset collateral baskets are not modelled, and every one of them makes the real position worse than shown.

What this calculator does
For an over-collateralised loan of the kind most lending protocols issue, it returns your current loan-to-value ratio, the value of your collateral, the collateral price at which the position is liquidated, how much room that leaves, and the two routes back to a safer ratio.
How liquidation actually happens
Loan-to-value is what you owe divided by what your collateral is worth. Because the numerator is fixed in dollars and the denominator moves with the market, a falling collateral price raises your LTV without you doing anything at all. When it reaches the protocol’s threshold the position is liquidated, typically by anyone who wants to, and typically with a penalty.
That is why the liquidation price is the number worth writing down before you borrow rather than discovering afterwards. Borrow $11,000 against 10 ETH at $1,870 with an 80% threshold and the ratio looks comfortable at 59% — but the liquidation price is $1,375, only about 26% below the current price. In crypto that is not a wide margin.
The two ways out
The last two cells show them, both sized to bring the position to a 50% LTV: post more collateral, or repay part of the debt. They are not equivalent. Adding collateral keeps your exposure and increases the amount at risk; repaying reduces both. Which is appropriate depends on why the ratio moved, and doing either during a fast decline is harder than planning to.
What is not modelled
Liquidation penalties, borrow interest accruing on the debt over time, oracle price lag, differing thresholds per collateral asset, multi-asset collateral baskets, and protocols that liquidate partially rather than entirely. Every one of those makes a real position worse than the figures here, and interest in particular means an untouched loan drifts towards liquidation on its own.
Frequently asked questions
What liquidation LTV should I enter? The threshold your protocol publishes for that specific collateral asset — it varies by asset and is not the same as the maximum you were allowed to borrow at.
Is this the same as a leveraged position? Related but not the same. For perpetual futures see the liquidation price calculator, which models margin rather than collateral.
Does a stablecoin collateral remove the risk? It removes most of the price risk, not all of it — see the stablecoin peg check.
