Retiree healthcare costs are a fundamentally different obligation than active employee medical expenses. Active employee health coverage is a current compensation cost recorded against today’s revenue. Retiree healthcare is a prior-service promise that lands on the balance sheet as a long-term liability. The active-employee side of the equation is well documented: KFF’s 2024 Employer Health Benefits Survey found average annual premiums of $8,951 for single coverage and $25,572 for family coverage, with employers absorbing the largest share of that bill. Pre-65 retirees cost employers more per person. That population is older, uses more medical services, and brings no offsetting productivity.
The cost structure shifts again once a retiree hits Medicare eligibility. Medicare becomes the primary payer, and the employer’s role narrows to supplemental and drug coverage, which costs less per person than pre-65 medical coverage but remains a recurring expense on the books. Combined with longer lifespans and employer health costs rising 5% to 7% a year, those obligations compound into liabilities that can dwarf the annual active-employee health budget.
The liability accounting difference
Active employee health premiums are run through the operating budget: pay the bill, move on. Retiree health costs feed an Other Post-Employment Benefit (OPEB) liability that must be measured, disclosed, and often pre-funded under GAAP and GASB standards. This turns a hidden expense into a visible line item that rating agencies, bondholders, and CFOs scrutinize. The Pew Charitable Trusts found that states reported about $749 billion in OPEB liabilities, with only about $69 billion in assets set aside to pay for them. Private employers face the same dynamic: a shrinking percentage now offer retiree health at all. KFF data shows just 24% of large firms that offer active-employee health benefits still provided retiree medical in 2024, down from 66% in 1988. Offloading that liability may help the balance sheet in the short term, but it dumps risk onto former employees and erodes a retention tool that once set employers apart.
The Medicare Advantage shift in retiree coverage
Employers that still offer retiree coverage are changing how they pay for it. KFF’s 2024 survey found that 56% of large employers offering retiree benefits to Medicare-age retirees now provide at least some coverage through a Medicare Advantage contract, more than double the 26% share in 2017. A carrier’s MA plan can price retiree coverage below what a self-funded supplemental plan costs, and it shifts administration off the employer’s books. The tradeoff is control. Retirees in a carrier’s plan follow that plan’s network and drug formulary, and the employer loses the direct relationship with its former workers. Retiree coverage is also a retention and recruitment signal to the current workforce. A system that keeps the employee inside the same coordinated care arrangement from active employment through Medicare age avoids that handoff.
The root cause stays the same
The underlying healthcare system runs on misaligned incentives whether a person is 45 or 65. Middlemen markups, opaque pricing, and a fee-for-service model that rewards volume over value drive up claims for every population. For employers, the retiree health liability is a live reflection of what happens when people age inside a system that charges more every year for the same, and often worse, outcomes. Traditional wellness programs rarely change that trajectory because they rely on participation points, not verified health actions that lower claims.
Reversing the cost curve across the entire benefits lifecycle
A WellthCare™ Plan changes the math by starting with the active employee and keeping them on the plan through their career. Employees get $0-co-pay preventive care, AI-drafted plans of care reviewed by a nurse practitioner and physician, and earn reward dollars for verified screenings, scans, and other plan-defined health actions. Those rewards are real, spendable dollars at the WellthCare Store™ on FSA-eligible products. The employer sees fewer claims against the primary plan because members use the WellthCare benefit first.
Lower claims today set a healthier trajectory. When a workforce moves through a plan year with fewer surprise bills and better managed chronic conditions, future retiree costs grow more slowly, because fewer high-cost episodes now mean fewer high-cost conditions later. An already-accrued OPEB obligation does not disappear overnight; what changes is the rate at which future claims grow. The plan’s cost transparency tools and prescription savings through WellthCare Pharmacy™ add another layer of immediate relief. At age 65, WellthCare Medicare™ keeps the employee inside the same coordinated system instead of pushing them off a cliff. The employer’s retiree health exposure drops because members remain healthier and because the program’s structure aligns incentives around prevention, not sick-care volume.
The retirement savings component closes the loop. Program savings fund automatic retirement contributions. Employees see their wealth build visibly from the preventive actions they take, which helps them afford healthcare in retirement and eases the pressure on employer-provided subsidies. The WellthCare Readiness Index™ then gives the employer its own data, not assumptions, on how much that healthier, more engaged workforce is saving and when to expand the approach.
