Calculated Output Metrics

Vault Health Factor (HF) 1.65
Current Loan-to-Value (LTV) 50.0%
Collateral Price Drop to Liquidation -39.4% Cushion
Safe Additional Borrowing Capacity $4,125.00

Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Health Factor = (Collateral Value × Liquidation Threshold) / Total Borrowed Debt

Step-by-Step Mathematical Derivation

1
Loan-to-Value Ratio

LTV = Borrowed Debt / Collateral Value = $12,500 / $25,000 = 50.0%.

2
Health Factor Derivation

HF = (Collateral × Liquidation Threshold%) / Debt = ($25,000 × 0.825) / $12,500 = $20,625 / $12,500 = 1.65.

3
Liquidation Price Threshold

Liquidation triggers when HF < 1.0. Critical Collateral Value = Debt / Threshold = $12,500 / 0.825 = $15,151.52.

4
Market Crash Safety Buffer

Allowable Drop = ($15,151.52 - $25,000) / $25,000 = -39.39%. Collateral can plummet by ~39% before liquidation bot liquidates the vault.

Frequently Asked Questions

What happens when a DeFi Health Factor drops below 1.0? +
The instant Health Factor drops below 1.0, third-party liquidation bots repay up to 50% of your debt and seize your collateral at a discounted penalty (typically 5% to 10% liquidation bonus).
What is considered a safe Health Factor in DeFi lending? +
Conservative DeFi practitioners maintain a Health Factor of 2.0 or higher (LTV ≤ 40%), providing enough cushion to withstand historic 50%+ single-day crypto market flash crashes.
