Your Benefits Load Factor Lies About Your Cheapest Seats

A services company I work with runs 34 people and prices every hiring decision off a 26% payroll load. Base salary times 1.26 and you have the budgeted cost of a seat. That figure came out of a spreadsheet somebody built in 2023 and it hasn't moved since.

Their January renewal landed at 13% on medical. The load factor stayed 26%.

Premiums are dollars per head, not percent of payroll

This is where the arithmetic breaks. Payroll taxes do scale with salary. Health premium doesn't. Your carrier charges the same monthly rate for the $68K coordinator and the $180K engineer.

Say your blended employer contribution is $1,100 a month, or $13,200 a year per covered employee. On the engineer that's 7% of base. On the coordinator it's 19%. One load factor can't describe both seats, and the spread widens every year premiums climb faster than wages.

An 11% renewal adds roughly $1,450 per covered head. Call it eight tenths of a point of burden on the engineer and better than two points on the coordinator. Guess which roles growing companies hire in volume.

The 2027 number is already on file

You don't have to wait for your broker's October call. Carriers file small group rates with state regulators in the spring, and those filings are public. CMS posts the full individual and small-group set for 2027 on July 31.

Several states are already out. Pennsylvania small group insurers requested an enrollment-weighted average of 11.5% for 2027. Michigan carriers asked 9.6% on plans under 51 employees, after 11.1% got approved for this year. Small group medians ran near 11% nationally for 2026. Two consecutive double-digit years compound to about 23%.

That moves $13,200 per head to roughly $16,300. On 34 covered employees it's $105K nobody budgeted, and it arrives disguised as a benefits line variance.

Your renewal isn't a benefits decision. It's a repricing of every open role in your hiring plan, and it lands nine months after you signed off on the plan.

What to do in the next two weeks

Pull your carrier's 2027 filing for your state and size band. Your broker can send it, or it's on the state insurance department site. Use it as the planning number until the actual quote shows up.

Then re-derive the load factor by role instead of for the company. Take budgeted base. Add employer payroll tax at actual, remembering that Social Security caps at $184,500 in 2026, which quietly flatters your senior seats. Add the per-head benefits dollars. Add whatever else is flat per employee.

Run it three times: one junior seat, one mid, one senior. You'll get three numbers spread 10 points or more.

Then use the right one for each open req. A hiring plan weighted toward junior roles costs more per dollar of salary than your model says, and that's the plan most companies at $2M to $20M are actually running.

One percentage applied to every seat was always a shortcut. Two years of double-digit renewals turned it into a bad one.
