HOMA-IR Calculator

Estimates insulin resistance from fasting glucose and fasting insulin. Lower scores mean better insulin sensitivity. HOMA-IR is one of the most widely used markers for metabolic health.

Formula

HOMA-IR = (Fasting Glucose × Fasting Insulin) ÷ 405

Fasting Glucose (mg/dL)

Fasting Insulin (µIU/mL)

Interpretation

< 1.0 — Optimal insulin sensitivity

1.0–1.9 — Early insulin resistance

2.0–2.9 — Significant insulin resistance

≥ 3.0 — Severe insulin resistance

When is this useful?

HOMA-IR helps detect insulin resistance before blood sugar rises to prediabetic levels. It's widely used in metabolic health, diabetes prevention, and by people following keto, carnivore, or low-carb diets to track improvements in insulin sensitivity.

Both values must be fasting (8–12 hours) for an accurate result.
