Budget Impact Analysis (BIA) Services
Cost-effectiveness tells a payer whether an intervention is good value. A budget impact analysis tells them whether they can afford it. The two answer different questions, and most reimbursement decisions need both. EvySaif builds clear, payer-ready budget impact models that project the financial consequences of adopting a new treatment over a defined time horizon.
Affordability over a realistic horizon
A budget impact analysis estimates the change in total spending when a new intervention enters a defined population, usually over a one to five year horizon matched to the payer's planning cycle. Built to ISPOR good-practice principles, the model lets a payer see the year-by-year financial picture and test it against their own assumptions.
Size the eligible population
Eligible-population sizing uses epidemiology and market-share inputs, accounting for the size and growth of the population the intervention will actually reach.
Project the treatment mix
The model reflects the current and projected treatment mix, so the comparison is against what payers actually fund today, not a convenient baseline.
Count the full costs
Drug and administration costs, and the downstream costs avoided or added, are all in the model, giving the total change in spending rather than the drug price alone.
Make it testable
Scenario and one-way sensitivity analysis on the key drivers, and interactive payer-facing models with adjustable inputs where required, so a formulary or reimbursement committee can stress-test the model rather than take a black box on trust.
Value and affordability are different questions: a cost-effectiveness analysis measures value (cost per unit of health gained); a budget impact analysis measures affordability (the total change in spending). Payers typically want both, and we build them as a pair on one consistent evidence base.

How EvySaif helps
We build budget impact models that are transparent and adjustable, so a payer can stress-test them rather than take a black box on trust. The structure follows ISPOR good practice, and the model is paired naturally with the cost-effectiveness work when a submission needs both.
Why EvySaif
As one of the best research and medical writing consultancies in India, EvySaif pairs clinical depth with regulatory rigour. The clinical and epidemiological assumptions in our budget impact models are clinician-reviewed, the structure follows ISPOR good practice, and the model is paired naturally with the cost-effectiveness work when a submission needs both. For Gulf and Indian payers, we adapt the cost and population inputs to the local market.
Frequently asked questions
A cost-effectiveness analysis measures value (cost per unit of health gained). A budget impact analysis measures affordability (the total change in spending). Payers typically want both.
Usually one to five years, matched to the payer's planning cycle, since budget impact is about near-term affordability rather than lifetime value.
Yes. We can build payer-facing models with adjustable inputs so stakeholders can run their own scenarios.
