FAQs
What is the difference between a cost calculator and a health economic model?
A health economic model is a comprehensive framework (typically built in Excel) that evaluates long-term costs and outcomes. In contrast, a cost calculator translates validated HEOR models into an interactive, user-friendly tool. An example is a HEOR budget impact calculator, which enables real-time scenario testing and makes complex economic insights easier to apply in payer discussions.
How are cost calculators used in payer and HTA discussions?
Cost calculators are used in payer and HTA discussions to explore ‘what-if’ scenarios such as changes in pricing, population size, or treatment uptake. They help visualize budget impact, cost-effectiveness, ROI, and potential costs offset in health economics during live conversations – supporting more transparent and data-driven reimbursement discussions.
Are interactive cost calculators compliant with regulatory and HTA requirements?
When built correctly, yes. Compliant cost calculators are grounded in validated economic models and include controls, such as version tracking, locked assumptions, audit trails, and market-specific adaptations. These features help ensure alignment with HTA guidelines and internal governance, allowing teams to use calculators confidently in regulated market access environments.
Can cost calculators be customized for different countries and payer systems?
Typically, dynamic cost calculators in health economics can be localized across countries and payer systems. Users can adapt inputs such as currency, epidemiology, treatment pathways, and reimbursement rules. This allows global organizations to ensure alignment while still addressing local HTA requirements and stakeholder expectations.

What data is needed to build a reliable cost calculator?
A reliable cost calculator typically requires clinical outcomes data, cost inputs, population parameters, and assumptions from validated HEOR models. Increasingly, real-world evidence (RWE), such as claims or registry data, is incorporated to reflect routine clinical practice. Clear documentation and transparent assumptions are essential to ensure credibility and stakeholder trust.
