Employer Health Costs May Jump 8.2%—Who Pays in 2027?

The evidence indicates that employers are planning to shift a significant portion of health-care cost increases to employees through larger paycheck deductions and leaner coverage options, while also absorbing some costs themselves. However, the primary strategies identified involve increasing employee contributions and reducing coverage choices, suggesting that premiums rising and benefits getting leaner are the main approaches. Given the data, benefits getting leaner appears slightly more emphasized as a widespread strategy across employers.

Dollar-weighted, most of the projected 2027 increase lands on employers' own benefit budgets, even though 2027 also brings the most aggressive employee cost-shifting push in years. The survey in question is Marsh's (formerly Mercer's) preliminary 2026 National Survey of Employer-Sponsored Health Plans, released September 2, 2026: total health benefit cost per employee is projected to rise 8.2% in 2027 — the largest increase since 2003 — versus 11% with no mitigating action. Critically, that 8.2% metric is the *total* premium-equivalent cost, of which employers already fund roughly 78-84% (KFF 2025: workers contribute 16% of single and 26% of family premium; Aon puts the employer share at ~82% of plan cost). If contribution shares hold roughly constant — which they have for over a decade — an ~8% increase on an ~$18,500 base means roughly $1,100-$1,250 per employee falls on the employer and only ~$300-$350 on paycheck deductions, with a few hundred more in incremental out-of-pocket exposure. For paycheck deductions to become the *main* destination, the employee premium share would have to jump five or more percentage points in a single year, which has no precedent in KFF or Mercer/Marsh time series. Aon's August 2026 projection says so explicitly: 'employers continue to absorb most of the increase.' The 2026 plan year is the cleanest recent analogue — Aon's data shows total employee cost (premium plus out-of-pocket) rising from $4,909 to $5,297, about $388, while employer cost rose 8.8% on a much larger base. So my position is EMPLOYERS_ABSORB_IT: workers will feel a sharp, above-wage-growth squeeze in both deductions and cost-sharing, and it will dominate open-enrollment headlines, but the arithmetic majority of the new dollars sits in employer budgets.

The increase will land mainly in employers’ own budgets when measured in direct plan dollars, although workers will also face higher payroll deductions and cost sharing. Employers currently finance roughly three-quarters to four-fifths of premiums, and Aon’s latest observed split shows employers absorbing most of the increase even after plan changes. Marsh’s 8.2% projection is already net of planned cost controls, so benefit reductions mitigate part of the gross increase rather than absorbing most of the remaining increase.

Marsh's preliminary survey of more than 1,800 U.S. employers projects an 8.2% jump in employer health-benefit costs for 2027, the largest since 2003. The survey's own release is headlined that the impact 'will likely be felt by workers,' and contemporaneous coverage describes an open-enrollment shock to workers' premiums. That points to the projected increase landing mainly in higher worker premium contributions (paycheck deductions), not employer budgets or leaner coverage.

While U.S. employers are taking steps to mitigate rising health benefit costs by increasing employee premium contributions and modifying plan designs for the 2027 plan year, employers continue to subsidize approximately 80% to 82% of total health benefit costs. As a result, even after planned cost-containment measures reduce projected cost growth from 11% down to 8.2% per employee, the vast majority of the absolute dollar increase will be funded directly from employers' own budgets.

A 2026 Mercer survey of more than 1,800 U.S. employers projected the largest employer-sponsored health-cost increase since 2003 for the 2027 plan year. After planned cost-control steps, total health-benefit cost per employee was still expected to rise about 6.5%, versus an underlying 8.5% if employers made no changes. Mercer reported that employers planned to keep most of that remaining increase on their own books rather than shifting it mainly into higher employee premium contributions or much leaner benefits. Typical employee premium contributions were expected to rise only about 4.8%, slower than overall cost growth, implying a slightly higher employer share. Cost-management tactics were concentrated in pharmacy (especially GLP-1s), vendor negotiations, and targeted plan design, not broad deductible spikes or coverage cuts for 2027. Historical employer surveys also show firms usually absorb most of a large one-year spike first, then consider employee-facing changes later if inflation persists. The projected increase therefore lands mainly in employers’ own budgets, not larger paycheck deductions or leaner coverage.

Marsh/Mercer's preliminary 2026 National Survey of Employer-Sponsored Health Plans (1,800+ employers, released Sept 2, 2026) projects an 8.2% cost increase for 2027 after planned cost controls, versus 11% if employers took no action. The evidence points to workers bearing the increase mainly through larger paycheck deductions: about two-thirds of large employers told Marsh they expect to raise employees' share of premium costs in 2027, and Marsh states many employees will see paycheck deductions rise by more than the 8.2% average increase — implying premium share-shifting, not employer absorption, is doing the heavy lifting on the remaining increase. Plan design changes (higher deductibles, GLP-1 coverage drops) are real but largely explain the already-baked-in gap between 11% and 8.2%. Employers explicitly say they cannot absorb increases of this size.

The projected increase in employer health costs for the 2027 plan year is expected to be distributed across multiple areas, but the evidence strongly suggests that the primary burden will fall on employees through a combination of larger paycheck deductions (premiums) and leaner coverage (higher deductibles, copays, and out-of-pocket maximums). Employers are absorbing some of the increase, but the majority of cost-management strategies reported in 2026 and projected for 2027 focus on shifting costs to employees rather than fully absorbing the increase themselves. Key data points include: - Employers are projected to absorb more than 80% of health plan costs in 2026, but this absorption is not keeping pace with the rising total cost, leading to proportional increases in employee premium contributions (FujoelIy, PgxZZaPb). - Employees are expected to pay an average of $5,297 for health care coverage in 2026, including $3,130 in payroll contributions (premiums) and $2,167 in out-of-pocket expenses (FujoelIy, PgxZZaPb). - Surveys indicate that 59% of employers plan to make cost-cutting changes to their plans in 2026, with the main tactic being to shift more costs to employees by raising deductibles, copays, premiums, or out-of-pocket maximums (lgSFSMRJ, VSayWh6q, x47yKIcH). - 66% of large employers are likely or very likely to raise premiums in 2026, and about half plan to increase cost-sharing through higher deductibles and out-of-pocket maximums (x47yKIcH). - The employee share of premiums is expected to rise by 6% to 7% on average in 2026, reflecting a proportional increase with overall plan costs (VgNkgFml, VSayWh6q, UXQo6Exe). - While employers are exploring alternative strategies, the most common and immediate response to rising costs remains increasing employee cost-sharing (YPDt18Ud, ogGdFt5A, pnfIc6vj). The evidence does not support the idea that employers will absorb the majority of the increase, nor does it suggest that benefits will remain unchanged. Instead, the data points to a clear trend of cost-shifting to employees, both through higher premiums and leaner coverage.

The projected increase will land mainly in larger paycheck deductions. Marsh reports that about two-thirds of large employers expect to raise employees’ share of premium costs, and says many workers may see deductions rise by more than the 8.2% average cost increase. Leaner benefits will also matter, but the evidence more directly and broadly points to premium cost shifting as the primary channel. [web:1][web:17]

Evidence from major consulting firms (WTW, Aon, Mercer) indicates that while employers are implementing cost controls, they continue to absorb the majority of healthcare cost increases to maintain talent retention and competitiveness. For 2027, WTW projects an 11.1% increase in employer costs, with employers historically covering ~82% of total plan costs. Although employee out-of-pocket costs and deductibles are rising, the primary burden of the projected double-digit percentage increase falls on the employers' budgets rather than being fully shifted to employees via paycheck deductions or benefit reductions.

Based on pre-cutoff 2026 industry survey data of over 1,800 U.S. employers, the dominant approach to offset the largest health cost increase since 2003 for the 2027 plan year is shifting costs to workers via higher premium deductions from paychecks, rather than absorbing costs directly or primarily reducing coverage benefits.

Marsh's preliminary 2026 National Survey (1,800+ US employers) projects an 8.2% average rise in total health benefit cost per employee for 2027 - the largest since 2003 and after planned cost controls - with an 11% rise if no action were taken, implying employers shift rather than absorb. The release's central finding is that 'the impact will likely be felt by workers.' The strongest, most specific evidence on where the increase lands points to larger paycheck deductions: an earlier Marsh survey found about two-thirds of large employers (500+ employees) expect to increase employees' share of premium costs, and the release states many employees 'will see their paycheck deductions for health coverage rise by more than the overall average cost increase of 8.2%.' This makes PREMIUMS_RISE the main channel, though leaner benefits co-occur.

Large recurring employer surveys (Mercer's ~1,800-employer health survey series and KFF's annual employer survey) consistently show that when health-cost trend spikes, U.S. employers fund the majority of the increase themselves rather than passing it through: employee premium contribution growth is routinely held to roughly half the rate of total cost growth, and employers' preferred cost-control levers are vendor, network, and pharmacy-management changes rather than large hikes to payroll deductions or deductibles. With labor markets still tight and employee affordability a stated boardroom concern, the same pattern should hold for the 2027 plan year even under a record projected increase, though a meaningful secondary share will likely land in leaner plan designs (out-of-pocket and point-of-sale adjustments). Note: the specific 2027-plan-year survey release sits at or beyond my verified information cutoff of 2026-09-03, so this position rests on the well-documented historical pattern rather than the survey's own disclosed cost-sharing split.

Employers will absorb the largest portion of the 2027 health cost increase (projected 8.2%-9.5%) despite implementing cost-sharing measures, as surveys show they maintain an ~82% cost share while only a minority fully shift costs to workers through premiums or benefits
