The standard way to estimate insulin resistance when you have a fasting insulin result.
Both values must come from the same fasting blood sample. Nothing is stored — the maths runs in your browser.

HOMA-IR stands for Homeostatic Model Assessment of Insulin Resistance. It estimates how hard your pancreas is working to keep your blood sugar normal.
The logic is simple. If your glucose is normal but your insulin is high, your body is only keeping glucose in range by producing extra insulin — that is insulin resistance. If both are low-normal, your insulin is working efficiently.
| Value | Common interpretation |
|---|---|
| Below 1.0 | Insulin sensitive — considered optimal |
| 1.0 – 2.0 | Normal range for most laboratories |
| 2.0 – 2.9 | Early insulin resistance becomes more likely |
| 3.0 or above | Significant insulin resistance more likely |
Below 1.0 is generally considered optimal and below 2.0 within the normal range for most laboratories. Values of 3.0 or above are more often associated with significant insulin resistance.
Yes. Switch the unit selector and the calculator converts to µIU/mL first, dividing by 6.0, which is the conventional factor.
Yes. HOMA-IR reflects the fasting state only. Someone can have normal fasting values but a poor response after meals, which this cannot see.
Most routine panels do not include it. The TyG index was designed for exactly that situation, estimating insulin resistance from triglycerides and glucose instead.
HOMA-IR is one marker. PhisBio Lab reads your whole blood panel and shows how five body systems are doing.
