What Moves the Needle Most
How much each factor changes your Brand Total across its full range. Brand / Month has the biggest impact.
Focus your attention on Brand / Month — getting it right matters most. Factors lower down move the result less, so rough estimates there are fine.
Confidence & Assumptions
The outcome shifts meaningfully with your assumptions. Sensible, but revisit the key inputs.
Brand Total: €8,640 (worst) → €7,200 (expected) → €6,120 (best)
These are the estimates the result depends on. Adjust them (and the Advanced inputs) to match your real situation — the closer they are to reality, the more reliable your decision.

How This Calculator Works
What this calculator does
Project brand versus generic medication spend over multiple years and see the gap after an optional adherence-risk cushion.
How the calculation works
Brand total is monthly cost × 12 × years. Generic adds a one-time (or lump) adherence-risk cushion on top of its monthly path.
Formula
Brand = BrandMonthly×12×Years Generic = GenericMonthly×12×Years + AdherenceRisk
Example
€120/mo brand vs €25/mo generic over 5 years is a large gap even after a €200 adherence cushion on the generic path.
