Enter the fasting glucose and fasting insulin into the calculator to determine the Homa Index. This calculator can also evaluate any of the variables given the others are known.

Homa Index Formula

The following formula is used to calculate the Homa Index.

HI = (Fasting Glucose * Fasting Insulin) / 405


  • HI is the Homa Index
  • Fasting Glucose is the fasting blood glucose level (mg/dL)
  • Fasting Insulin is the fasting insulin level (μU/mL)

To calculate the Homa Index, multiply the fasting blood glucose level by the fasting insulin level. Then divide the result by 405.

What is a Homa Index?

A Homa Index, or Homeostatic Model Assessment, is a method used to quantify insulin resistance and beta-cell function. It is derived from fasting glucose and insulin concentrations. This index is commonly used in epidemiological studies and clinical research to assess insulin resistance, a condition that is often associated with type 2 diabetes and cardiovascular disease.

How to Calculate Homa Index?

The following steps outline how to calculate the Homa Index.

  1. First, determine the fasting blood glucose level (Fasting Glucose) in mg/dL.
  2. Next, determine the fasting insulin level (Fasting Insulin) in μU/mL.
  3. Next, gather the formula from above = HI = (Fasting Glucose * Fasting Insulin) / 405.
  4. Finally, calculate the Homa Index.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Fasting Glucose (mg/dL) = 100

Fasting Insulin (μU/mL) = 10
