Employer coverage ยท Updated September 2026

Which funding structure fits your company?

Six ways to fund employer coverage. What each one makes possible, what it asks you to take on, and which one tends to win at your size and census.

Short answer: group size sets what's available to you, and census age sets which available option is cheapest. Under about 25 employees, most groups do best with a fully insured plan, a CHOICE Arrangement (the new federal name for an ICHRA), or a guaranteed issue, shelf-rated plan (one flat rate for everyone, regardless of age or health). Between 25 and 100, level funding usually wins. Above 100, self-funding opens levers that are structurally unavailable below it. Self-funding a 20-person group is legal, common, and usually a bad trade.

What are my options? The 6 ways to fund employer coverage

Six structures: fully insured, CHOICE Arrangement (formerly ICHRA), guaranteed issue shelf-rated, alternative shelf-rated through a sponsored benefit fund, level funded, and self-funded with stop-loss.

Ranked by what the employer takes on, not by which is better. The right answer depends on your census, your claims history and how much month-to-month variability your cash position can absorb.

StructureHow it's pricedEmployer keepsEmployer takes on
Fully insuredAge-rated inside the ACA 3:1 federal band, by rating area. Some states compress the band or use pure community ratingFull certaintyNothing beyond the premium

The number most people miss

Fully insured, level funded and self-funded are not priced on the same thing. Compare them on total plan cost per enrolled employee per month, employer share plus employee share, medical and Rx only.

For level funding, compare the maximum funding rate against fully insured premium. That's the guaranteed ceiling, and it's the only apples-to-apples line. Expected cost after surplus return is a second, separate number. Comparing a premium to a projection isn't a comparison.

What each one unlocks

What does each funding structure unlock?

This is the part that changes the decision. Several of the largest cost levers in employer healthcare aren't options a fully insured employer has declined. They're structurally unavailable until the funding chassis changes, because the employer doesn't own the contract and never sees the claims.

By company size

Which funding structure fits my company size?

Short answer: under 25 enrolled, fully insured, a CHOICE Arrangement or shelf-rated. 25 to 100, level funded. Over 100, self-funded with the full lever stack.

Size doesn't tell you what's best. It tells you what's on the menu. Stop-loss carriers set minimum enrollment thresholds, and those thresholds are the real gate.

EnrolledRealistically availableUsually comes out aheadWhy
1 to 9Individual market, CHOICE Arrangement, guaranteed issue shelf-rated plan, fully insured in some statesCHOICE Arrangement or shelf-ratedSmall-group participation minimums are hard to clear. Shelf rates ignore a small, older census entirely
10 to 25Fully insured, CHOICE Arrangement, shelf-rated, level funded in some statesDepends almost entirely on average ageThis is the crossover band. Young census favors age-rated. Older census favors shelf-rated
26 to 50Fully insured, level funded, CHOICE Arrangement, PEO, shelf-ratedLevel funded with a steered HRA overlayFirst size where you can own claims data and still cap the downside contractually
51 to 100Level funded, self-funded, group captive entry in some programsLevel funded, moving to self-fundedEnough claim volume for experience to start meaning something

The crossover

Age-rated or shelf-rated? Where the crossover happens

Rule of thumb: average age under 35 usually wins on age-rated. Average age over 45 usually wins on shelf-rated. In between, model both.

Age-rated means the premium changes with each employee's age. Shelf-rated means one published rate per coverage tier, identical for a 24-year-old and a 64-year-old, anywhere in the country.

ACA small-group premiums are age-rated. Federal rules allow up to a 3:1 spread between the oldest and youngest adult rate, so a 64-year-old can be priced at three times a 21-year-old for the identical plan. A handful of states compress that band further, and two use pure community rating.

Shelf-rated plans work the opposite way. A short list of coverage tiers, one published rate for each, no age rating, no census collection and no medical questions. That produces a predictable crossover.

Census profileAge-rated small groupShelf-rated planTypical outcome
Average age under 35, few dependentsPriced near the bottom of the 3:1 bandPays the same flat rate as everyoneAge-rated wins, often by a wide margin
Average age 35 to 45Mid-bandFlatClose. Model both
Average age 45 to 55Upper-band, climbing fastFlatShelf-rated often wins
Average age 55+Near the top of the bandFlatShelf-rated usually wins, sometimes substantially
Known high-cost claimantCommunity-rated pool absorbs it, but renewals reflect the blockGuaranteed issue, no medical underwritingShelf-rated removes underwriting risk entirely

Why this matters for older and less healthy groups

A 12-person landscaping company with an average age of 57 and two diabetics is expensive to insure in the age-rated market and hard to underwrite for level funding. A shelf-rated plan doesn't ask. It's the same rate it charges a 24-year-old.

That's not a loophole. It's what happens when a plan prices a national pool instead of your twelve people. Eligibility rules apply and not every employer qualifies.

The reverse is just as true. A 12-person design studio with an average age of 29 is subsidizing that same national pool, and will almost always do better age-rated.

By industry

Which funding structure fits my industry?

Industry is a proxy, and it's worth saying plainly: census age and dependent take-up predict the answer better than industry does. Two restaurants with 40-year and 26-year average ages land in different places. Use the table as a starting hypothesis, then check the census.

In practice

What does this look like in practice?

About this example

The company below is illustrative, drawn from the patterns in real engagements, with identifying details removed and figures rounded. It is not a specific client and not a projection of your results.

A 62-employee specialty manufacturer, average age 44, 58% enrolled in a dependent tier, currently fully insured on a PPO. Total plan cost sits above the published benchmark for their size and region.

They move the chassis to level funded at renewal. The maximum funding rate lands below the renewal premium, which is the day-one number. Because they now own the contract and the claims data, three levers that were unavailable to them open at the same time: a pass-through pharmacy arrangement, a steered out-of-pocket HRA that zeros member cost at high-performing providers, and a musculoskeletal program aimed at their highest-frequency claim category.

Employees move to a leaner plan design on paper and pay less out of pocket in practice, because the HRA covers the gap where they're steered. Nobody lost coverage, nobody lost a job, and the employer's budget dropped on the first invoice.

Typical results across engagements of this shape run in the range of 15% to 25% of plan cost, with the full lever stack reaching up to 20% to 30% at larger sizes. Actual results depend on census, claims history, enrollment and which levers the structure supports. Savings ranges from different levers are not additive.

Methodology and important disclosures

What this page is. An educational comparison of funding structures available to employers. It is not a quote, an offer of coverage, a recommendation of any specific plan or carrier, or advice about what is suitable for your organization. Suitability depends on your census, claims history, cash position and risk tolerance, none of which this page knows.

Availability. Not all structures described here are available in all states, at all group sizes, or to all employers. Guaranteed issue shelf-rated programs and sponsored benefit fund programs carry eligibility conditions and participation requirements, and are not available to every employer. Availability is determined by the program, not by this page.

Ranges. All savings figures are stated as ranges and reflect outcomes observed across engagements, rounded. They are not guarantees and not projections of your results. Savings ranges from different levers are not additive. Statements about retention, attraction, absenteeism and workplace outcomes describe the mechanisms by which these programs are designed to work. They are not quantified performance claims and no specific result is promised.

Program components. Bundled care components described on this page are available a la carte and vary by employer, state, group size and eligibility. Availability, covered services, visit terms and any utilization or clinical-appropriateness limits are set by each program and its published terms, not by this page. Where visits are described as unlimited, that reflects no per-member visit cap under the program terms and remains subject to clinical appropriateness and the program's own conditions of use. The medication count reflects the current formulary and is subject to change.

Member discounts. Legal, identity theft, cyber, caregiver and dependent care, pet care and household service benefits are discount and membership programs, not insurance. They do not pay providers, they do not coordinate with a health plan, and availability varies by state and by program.

Benchmarks. Group premium benchmarks derive from the KFF Employer Health Benefits Survey. Individual market data derives from CMS Public Use Files. Trend projections derive from published reports by Aon, Mercer and PwC. Each is cited as of its publication date and restates national or regional averages, not your market.

Fixed indemnity and supplemental products. Accident protection and any supplemental, hospital indemnity or fixed indemnity products referenced on this page or elsewhere on this site pay a fixed amount based on a covered event rather than on medical cost. They are not major medical coverage, are not minimum essential coverage, and are not a substitute for comprehensive health insurance.

Terminology note. CMS and the SBA renamed the individual coverage HRA the CHOICE Arrangement on September 3, 2026. That was an agency terminology change, not a statutory one, and the underlying ICHRA regulations are unchanged. Last reviewed September 2026. Benchmarks refresh annually when KFF publishes, typically in October.
