DeFi Lending Health Factor and Liquidation Scenarios

A lending health factor combines collateral valuation and borrowing exposure under a protocol-specific formula. Falling collateral value or increasing borrowed debt can push an account toward liquidation.

How to work through the calculation or research

Use the specific protocol’s asset-level liquidation thresholds rather than an arbitrary constant. Mark prices and oracle behavior can differ from a centralized exchange chart. Model changes in collateral, debt interest and fees over time.

A concrete worked example

A simplified model with $1,000 of collateral, an 80% liquidation threshold and $500 of debt gives a health factor of 0.80×1,000/500 = 1.6. That arithmetic assumes one asset and ignores liquidation penalties and protocol-specific details.

Common errors and important limitations

The risk of liquidation may increase rapidly in volatile markets, and protocols can change parameters. Never treat a generic worksheet as a live account monitor.

Put the idea into practice with a working tool

For a practical calculation, the Collateral Health Factor Scenario lets you examine: Collateral market value, Liquidation threshold (%), Debt value. The tool documents its method as: Health factor = collateral value × liquidation threshold / borrowed value.. Simplified single-collateral lending measure; oracle, reserve and protocol rules may differ. Scenario only; uses user-supplied values, not live rates.

Practical checks before relying on the result

• Confirm the asset, chain, amount and date apply to your own situation.
• Separate supplied assumptions from verifiable source data and do not treat a scenario as a live market quote.
• Document fees, rounding rules and constraints before making an irreversible financial or blockchain decision.
