Health Factor = Collateral Value (LTV-adjusted) / Debt
- HF ≥ 1.0 → Safe
- HF < 1.0 → Liquidatable
If your health factor drops below 1.0, anyone can liquidate your position.

| Cause | Effect |

| HF | Status | Action |
|---|
| > 1.5 | Safe | Monitor normally |
| 1.2–1.5 | Caution | Watch market moves |

Example
You have 600portfolioat65300 debt:
Collateral value = $600 × 0.65 = $390
HF = $390 / $300 = 1.30 ✓
Price drops 20% → portfolio now $480:
Collateral value = $480 × 0.65 = $312
HF = $312 / $300 = 1.04 ⚠️
Another 5% drop → liquidatable.
