Core formulas behind the calculator
Covered Lives = Total Employees × Average Covered Lives × Enrollment Rate
Projected Claimants = Covered Lives × Specialty Utilization Rate
Base Allowed Spend = Projected Claimants × Average Annual Specialty Cost × Case Mix Factor
Trended Allowed Spend = Base Allowed Spend × (1 + Annual Trend Rate)^(Projection Months ÷ 12)
Gross Allowed Spend = Trended Allowed Spend + (Trended Allowed Spend × Pipeline Shock Rate)
Plan Claims Before Offsets = Gross Allowed Spend × Plan Paid Share
Net Claim Cost = [Plan Claims Before Offsets − Manufacturer Assistance] − Stop-Loss Recovery
Total Employer Spend = Net Claim Cost + Admin Fees + Contingency Margin
PEPM = Total Employer Spend ÷ Covered Lives ÷ Projection Months

FAQs
1) What is specialty drug spend?
It is the portion of pharmacy spending tied to high-cost, complex medications, often used for chronic, rare, or serious conditions that require close monitoring and specialty distribution.
2) Why does utilization matter so much?
Even a small increase in specialty claimants can move plan costs sharply because each claimant usually carries a very high annual allowed amount compared with traditional prescriptions.
3) What does case mix factor mean?
Case mix factor adjusts average claimant cost upward or downward based on disease severity, therapy type, site of care, and the presence of very high-cost gene or biologic treatments.
4) How is manufacturer assistance treated here?
This model treats manufacturer assistance as an offset against plan exposure. Real contracts vary, so finance teams should align the assumption with actual benefit design and vendor rules.
5) What is stop-loss recovery?
Stop-loss recovery represents reimbursements from a stop-loss carrier after eligible claims exceed attachment points. It lowers the employer’s retained specialty drug liability.
6) Why include a contingency margin?
Specialty costs are volatile. A contingency margin adds a deliberate budget cushion for unexpected new therapies, claimant spikes, site-of-care changes, or pricing pressure.
7) What does PEPM tell me?
PEPM means per employee per month in this context of covered lives spending. It helps compare specialty burden across time periods, plan options, or employer groups.
8) Is this enough for final budgeting decisions?
It is a planning tool, not a full actuarial projection. Final budgets should also consider contract terms, rebate arrangements, diagnosis mix, and claim-level historical data.
