Mercer’s national survey of employer-sponsored health plans put the average employer cost at $17,496 per employee in 2025 — and employers expect it to pass $18,500 in 2026, a rise of roughly 6.5–6.7%, the sharpest in fifteen years. Before dependents.
For a big company, that’s a budget line. For a five-person firm, it’s a partner-level decision: sponsoring coverage for a small team is now a six-figure commitment. Here’s how to think about it without either overpaying or losing your next great hire over benefits.
The short answer
Budget roughly $18,000–$19,000 per employee per year for employer-sponsored health coverage in 2026 — before dependents — if you benchmark against national averages. Small firms typically pay more per head than the big-company averages, because small groups get none of the pooling leverage large employers enjoy. That’s the problem group purchasing exists to solve: pooled programs give small firms access to scale they can’t build alone, which is exactly how LawPAK structures its benefits panel. The wrong response to these numbers is offering nothing — in a talent market where big-firm offers set the bar, benefits are usually the second question a candidate asks.
Why the number keeps climbing
Prescription-drug spending is the engine — up over 9% among large employers in the latest survey — with medical inflation and utilization behind it. None of the forecasts show relief in 2026. Firms that budget for last year’s number get surprised at renewal; firms that budget the trend can plan compensation intelligently.
What a small firm can actually do
- Pool. Small-group purchasing programs exist precisely because a six-attorney firm negotiating alone has no leverage. Joining scale beats building it.
- Design the panel, don’t collect products. Medical, dental, vision, life, disability and 401(k) work as a package — a curated panel sized to your headcount, not six separate brokers’ favorite products.
- Use renewal advocacy. The first renewal quote is an opening position. Firms with representation routinely land meaningfully better than the first number; firms without simply sign it.
- Connect benefits to coverage. The plans you sponsor create exposures — employee benefits liability, fiduciary duty — that should be coordinated with your insurance suite, not discovered during a claim.
The recruiting math
The cost of benefits is visible; the cost of not offering them isn’t. It shows up as the associate who chose the firm across town, the paralegal who left for a hospital system, the recruiter fees for replacing both. Small firms don’t need to match a big firm’s benefits budget — they need a real package, professionally run, that says the firm is built to last. That’s a conversation with a benefits advisor, and it starts with your census, not a sales pitch.

FAQ
How much does health insurance cost per employee in 2026?
National survey data projects employer costs passing $18,500 per employee in 2026 (Mercer), after averaging $17,496 in 2025 — before dependent coverage.
Do small law firms pay more per employee than large employers?
Typically yes — small groups lack pooling leverage, which is why group-purchasing programs and pooled panels exist.
Is offering health benefits worth it for a five-person firm?
In a market where candidates compare against big-firm offers, benefits are usually decisive by the second question. The real decision is how to offer them efficiently, not whether.
What’s the fastest way to control benefits costs?
Pooled purchasing plus active renewal negotiation — and sizing the panel to your actual census instead of renewing last year’s design by default.
