Explore the decision boundary
A threshold values an additional unit of health within a particular decision context. Enter a more costly, more effective comparison, then move the selected threshold to see where incremental net monetary benefit changes sign. The threshold does not measure affordability or guarantee reimbursement.

Keep the questions separate: This graph addresses cost-effectiveness under stated assumptions. Budget impact analysis is still needed to assess affordability.
Method, interpretation and limits
ICER = ΔC ÷ ΔE
INMB = (threshold × ΔE) − ΔC
Break-even threshold = ΔC ÷ ΔE
INMB = (threshold × ΔE) − ΔC
Break-even threshold = ΔC ÷ ΔE
- A positive INMB supports the intervention on cost-effectiveness grounds at the selected threshold.
- A zero INMB means the alternatives are tied under the stated decision rule.
- A negative INMB supports the comparator on cost-effectiveness grounds at the selected threshold.
- The threshold's value, currency, price year, health unit, jurisdiction, source and institutional role must be reported.
- This educational explorer uses synthetic values, assumes a more costly and more effective comparison, and does not model uncertainty, affordability or wider HTA considerations.
