HOMA-IR Calculator: Estimate Insulin Resistance Using Your Lab Results

HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) is a research-based calculation that uses fasting glucose and fasting insulin to estimate how hard your body is working to keep blood sugar in balance. While it isn’t a diagnostic test, it’s a helpful indicator of whether your metabolism is becoming more or less insulin resistant over time. Enter your lab values below to calculate your HOMA-IR score:

Interpreting Your HOMA-IR Score

A lower HOMA-IR generally reflects better insulin sensitivity, meaning your body needs less insulin to keep blood glucose in a healthy range. Higher values suggest your body may be working harder to control blood sugar, which can be an early sign of metabolic strain. Because ideal ranges can vary by age, body composition, and lab differences, your number should be viewed as a general indicator rather than a diagnosis. It is most helpful when tracked over time. Discuss any concerns or questions with your healthcare professional.

Ranges Used in This Calculator:

• HOMA-IR < 1.0 — Typically associated with good insulin sensitivity
• 1.0 to < 2.0 — Borderline; some studies still consider this relatively insulin sensitive, others consider it mild insulin resistance
• 2.0 to < 2.5 — Often reflects mild to moderate insulin resistance
• ≥ 2.5 — More commonly associated with higher insulin resistance in many research studies
