HOMA-IR Calculator — Estimate Insulin Resistance
Calculate your HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) score online using fasting insulin and fasting glucose levels.
What is HOMA-IR?
HOMA-IR stands for Homeostatic Model Assessment of Insulin Resistance. It is a clinical calculation that estimates insulin sensitivity and pancreatic beta-cell function based on fasting blood glucose and fasting insulin levels.
The Metabolic Relevance of Insulin Resistance
Insulin is the hormone responsible for ushering glucose into your cells for energy. When cells become resistant to insulin, the pancreas must produce higher amounts to keep blood sugar stable. High HOMA-IR scores indicate insulin resistance, which is a key precursor to prediabetes, type 2 diabetes, metabolic syndrome, and cardiovascular disease.
Understanding the Formula
The standard HOMA-IR equation is: HOMA-IR = (Fasting Insulin (uIU/mL) * Fasting Glucose (mg/dL)) / 405. Optimal metabolic insulin sensitivity corresponds to a score below 1.0. Scores above 1.9 suggest early insulin resistance, while scores over 2.9 indicate significant metabolic resistance.
