How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Use the result with context

Health results are educational estimates, not a diagnosis or treatment recommendation. A qualified clinician can interpret measurements in the context of your health.

Formula and method

BMI over 21, FEV₁ 50–64%, walk distance 250–349 m and mMRC grade 2 give 0+1+1+1=3.

BODE = BMI points (0–1) + FEV₁ points (0–3) + mMRC dyspnea points (0–3) + six-minute walk points (0–3).

Worked example

Enter these known values and leave the other values blank.

Assumptions and limitations

  • Use clinically measured post-bronchodilator FEV₁ percentage of predicted, six-minute walking distance and mMRC dyspnea grade in a stable adult with COPD. The original 2004 validation is prognostic; this score does not give an individual survival probability or select treatment.
  • Clear the unknown field before solving the supported arithmetic inverse.
  • This clinical measurement model does not determine treatment.

Common questions

How is this model calculated?

BODE = BMI points (0–1) + FEV₁ points (0–3) + mMRC dyspnea points (0–3) + six-minute walk points (0–3).
