What percentage of health insurance do employers pay?

On average, 84% for single coverage and 74% for family coverage in KFF's 2025 survey.

Do employers have to pay 50% of health insurance?

There's no federal 50% rule, but many small group carriers require the employer to pay at least half of the employee-only premium. Large employers must meet the ACA's affordability standard.

Should a startup pay 100% of employee health insurance?

Most competitive startups do for employees, and many cover dependents too. It's one of the clearest benefits candidates compare.

What employers pay on average

KFF's 2025 survey found covered workers contribute 16% of the premium for single coverage and 26% for family coverage. That leaves employers paying 84% and 74%, or about $7,885 and $20,143 a year.

Are there minimums?

Carrier rules. Small group carriers commonly require the employer to pay at least 50% of the employee-only premium, along with a minimum share of eligible employees enrolling. Rules vary by carrier and state.
ACA affordability. Employers with 50 or more full-time equivalents must offer coverage where the employee's cost for self-only coverage is no more than 9.96% of household income in 2026, or risk penalties. Check yours with the ACA affordability calculator.
Under 50 employees. No federal requirement to offer coverage at all.

What startups usually do

Most venture-backed startups we talk to cover 100% of employee premiums and some or all of dependent premiums. The reason is hiring: candidates leaving large tech companies are used to paying little or nothing from their paycheck. When we design a plan, $0 employee premiums are usually the first line in the offer letter.

How to set your contribution

Start from your hiring market: what do candidates' current employers pay?
Price employee-only coverage at 100%, then decide on dependents (50%, 75% or 100%).
Model total annual cost, including PEO or admin fees.
Compare plans on what employees experience, not just premium.
