HOMA-IR calculator — your insulin resistance score
Enter your fasting glucose and fasting insulin to calculate HOMA-IR, a widely-used estimate of insulin resistance — with plain-English bands and why South Asians hit risk at lower thresholds.

Results are estimates based on the values you enter and standard formulas and reference ranges, which vary between laboratories and between individuals. Always discuss your results with a qualified healthcare professional. If you are experiencing a medical emergency, call 9-1-1.
HOMA-IR estimates insulin resistance from a single fasting glucose and fasting insulin: HOMA-IR = (glucose mmol/L × insulin mIU/L) / 22.5. It is a screening estimate, not a diagnosis.
Concerned about insulin resistance? Get an endocrinologist opinion — $45
Upload your fasting glucose, insulin, HbA1c and lipids and get a written opinion from a PGIMER/AIIMS-trained endocrinologist within 6 hours — what your HOMA-IR means and what to do. No referral needed.
Frequently asked questions
What is a normal HOMA-IR?
Broadly: below 1.0 suggests good insulin sensitivity, 1.0–1.9 is normal, 2.0–2.9 suggests early insulin resistance, and 3.0 or above suggests significant insulin resistance. Thresholds vary between labs and populations — South Asians are at risk at lower values.
What do I need to calculate HOMA-IR?
A fasting glucose and a fasting insulin drawn at the same time after an overnight fast. Ask your GP to add fasting insulin — it is often left off standard panels, yet it is what lets you calculate insulin resistance.
Can Ginie Health review my metabolic results?
Yes. A written opinion from a PGIMER/AIIMS-trained endocrinologist costs $45 CAD, delivered within 6 hours, with no referral needed — helpful for interpreting HOMA-IR alongside HbA1c and lipids.
