Formula

HOMA-IR = (fasting glucose mg/dL × fasting insulin µU/mL) ÷ 405
  • HOMA-IR Insulin Resistance Calculator calculates its result from Fasting glucose (mg/dL), Fasting insulin (µU/mL). It uses the formula HOMA-IR = (fasting glucose mg/dL × fasting insulin µU/mL) ÷ 405. Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
  • The main inputs are Fasting glucose, Fasting insulin. Enter them in the units and format shown in the calculator.
  • Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: HOMA-IR Insulin Resistance

Inputs
  • Fasting glucose: 90 mg/dL
  • Fasting insulin: 10 µU/mL

Using Fasting glucose (mg/dL) = 90, Fasting insulin (µU/mL) = 10, the calculated result is 2.2222222222.
