Rank alternatives using expected NMB
Enter expected cost and QALYs for mutually exclusive alternatives using the same population, perspective and time horizon. The comparator calculates option-level NMB, ranks the alternatives and reports the difference between the two leading options at the selected threshold.
Results at the selected threshold
| Alternative | Expected NMB | Rank |
|---|
Calculate to compare the alternatives.
Expected NMB across thresholds
Interpret carefully: The greatest expected NMB identifies the preferred option on cost-effectiveness grounds. It does not show affordability or require reimbursement.
Method, interpretation and limits
Option-level NMB = (threshold × expected health outcome) − expected cost
INMB between two options = NMB of evaluated option − NMB of comparator
INMB between two options = NMB of evaluated option − NMB of comparator
- The same threshold and analytical framework must be applied to every alternative.
- The option with the greatest expected NMB is preferred under the stated evidence and threshold.
- INMB must name the two alternatives and the direction of subtraction.
- The option with the greatest expected NMB may differ from the option with the highest probability of cost-effectiveness.
- This educational tool uses expected values and does not model parameter uncertainty, budget impact or wider HTA considerations.
