Crypto Loan Collateral Ratio Calculator
Crypto-backed loans require you to post collateral worth more than you borrow. The collateralization ratio measures that cushion: collateral value divided by loan value. This calculator converts your collateral and loan amounts into both a collateralization ratio and a loan-to-value (LTV) percentage, then compares your ratio to the minimum your platform enforces so you can see how much buffer protects you from liquidation.
Collateralization ratio formula
Collateralization ratio = (collateral value / loan value) * 100
LTV = (loan value / collateral value) * 100
Buffer = collateralization ratio - minimum required ratio
The collateralization ratio and LTV are reciprocals of each other. A ratio above the minimum required ratio means the position is healthy; a buffer at or below zero means the position is at or past the liquidation threshold.
How to read the result
- A higher collateralization ratio is safer: the collateral can lose more value before failing to cover the loan.
- LTV is the figure most lending protocols quote as a maximum allowable limit.
- The buffer is the percentage points your ratio sits above the platform minimum.
- Crypto collateral values change continuously; recheck the ratio whenever prices move.
Collateral ratio: frequently asked questions
What is a collateralization ratio?
The collateralization ratio is the value of your posted collateral divided by the value of your outstanding loan, expressed as a percentage. A ratio of 200% means your collateral is worth twice your debt. Higher ratios are safer because the collateral can fall further in value before it no longer covers the loan.
How is collateralization ratio different from loan-to-value (LTV)?
They are reciprocals. LTV is the loan divided by collateral (debt / collateral), while the collateralization ratio is collateral divided by loan (collateral / debt). An LTV of 50% equals a collateralization ratio of 200%. Lending protocols usually quote a maximum LTV; this tool shows both so you can match whichever your platform uses.
What collateralization ratio do crypto lending platforms require?
Each protocol sets its own minimum. Overcollateralized DeFi loans commonly require 150% or more, meaning maximum LTV around 66% or lower. The exact figure depends on the asset, its volatility, and the protocol. Enter your platform's minimum ratio so the calculator can show your buffer above it.
What happens if my ratio falls below the minimum?
If the collateral value drops far enough that your ratio crosses the protocol's liquidation threshold, the position can be liquidated: part or all of your collateral is sold to repay the loan, often with a penalty. Keeping a comfortable buffer above the minimum reduces this risk.
