What is willingness-to-pay (WTP)?

• A. The amount society or payers are willing to spend for health gains.
• B. The maximum price a patient will pay out-of-pocket.
• C. The minimum cost acceptable for a new drug.
• D. The average reimbursement rate used by payers.

Answer: (A)

Will­ingness-to-pay is the monetary value that people or a society place on health improvements, representing how much they are willing to spend to gain an additional unit of health (often framed as a QALY). This perspective—whether from the payer or societal standpoint—describes the value placed on health gains, not just the price charged or an individual’s out-of-pocket limit. In practice, WTP is used to set thresholds in cost-effectiveness analyses to decide if an intervention provides good value for money. It’s distinct from how much a patient will personally pay out of pocket, which is about affordability and individual budgeting, and it’s not the minimum cost acceptable for a new drug or the average reimbursement rate paid by insurers, which are cost or payment measures rather than the value placed on health benefits.
