HOMA-IR Insulin Resistance Calculator
Estimate insulin resistance from fasting glucose and insulin — the research index, with its honest limits.
HOMA-IR estimates how hard the pancreas works to keep glucose normal — useful in research and increasingly in metabolic check-ups, but the 'normal' cut-off genuinely varies by population (Indian/South-Asian thresholds run lower, ~2.0, reflecting higher metabolic risk). It needs a true fasting insulin (often not in standard panels) and is only a snapshot. Rising insulin can precede rising glucose by years — a reason it interests clinicians, who interpret it in context.

Frequently asked questions
How does the HOMA-IR Insulin Resistance Calculator work?+
HOMA-IR estimates how hard the pancreas works to keep glucose normal — useful in research and increasingly in metabolic check-ups, but the 'normal' cut-off genuinely varies by population (Indian/South-Asian thresholds run lower, ~2.0, reflecting higher metabolic risk). The calculation uses the formula: HOMA-IR = (fasting glucose mg/dL × fasting insulin µIU/mL) ÷ 405. Everything runs instantly in your browser as you type — your inputs are never uploaded.
Is the HOMA-IR Insulin Resistance Calculator accurate, and what is it based on?+
The method is traceable to authoritative sources: Matthews DR et al., Diabetologia 1985 — HOMA model. Results are estimates — individual variation always applies, so treat the output as a well-grounded starting point.
Is the HOMA-IR Insulin Resistance Calculator free and private?+
Yes. It's completely free with no sign-up, and all computation happens locally in your browser, so none of your health data ever leaves your device.
Can I use this for medical decisions?+
