Level funding gets pitched to small employers as a way to keep money that would otherwise go to an insurance company. That description is not wrong. It is just incomplete in the places that matter, and the parts left out are the ones that determine whether you are still in the arrangement three years from now.
The mechanics, without the sales layer
Under a level funded plan you pay a fixed amount every month, the same way you would under a fully insured policy. Inside that fixed amount are three separate things.
The first is a claims fund. This is money set aside to pay your employees’ medical and pharmacy claims. It is calculated from an expected claims level that the carrier’s underwriters set for your specific group.
The second is administration. Someone has to process claims, run the network, handle customer service, and produce reporting. That is a fee, and it is generally predictable.
The third is stop loss premium. This buys a cap. If any one person’s claims run past a specific deductible, the stop loss carrier picks up the excess. If total claims for the year run past an aggregate attachment point, usually set somewhere above expected claims, the stop loss carrier picks up that excess as well.
At the end of the plan year, the carrier settles. If your group used less than the claims fund, some or all of the difference comes back to you. If your group used more, stop loss absorbed it and your monthly payment never changed. That last part is why the arrangement is called level. Your cash flow looks like a fully insured plan even though you are funding claims.
Where it starts to work
The honest range where level funding becomes worth considering starts somewhere around 25 enrolled employees and generally stops being the right tool somewhere past 150, at which point full self funding usually offers better economics.
But the size is not really the test. Three other things matter more.
Your claims history has to be reasonably stable. Level funding is medically underwritten. The carrier is going to look at your group and set an expected claims level. A group with a couple of very large ongoing conditions will either be declined or priced so close to the fully insured alternative that the move is pointless.
You have to actually want the data. The real long term value of level funding is not the surplus check. It is that you finally see what your plan costs and why. If nobody at your company is going to read the reporting, you have taken on complexity in exchange for a lottery ticket.
You have to be able to absorb a bad renewal. This is the one that surprises people. Your monthly payment is protected during the plan year. It is not protected at renewal. A heavy claims year usually produces a heavy renewal, and the carrier may re underwrite you at that point.
The three questions worth asking before you sign
How is the surplus actually settled? Contracts vary widely. Some return one hundred percent of unused claims fund. Some return a percentage. Some return nothing unless you renew for another year. Some hold the settlement for months after the plan year closes while claims run out. All of these are legal and common. They are not equivalent, and the difference is real money.
What is the stop loss contract basis? This determines which claims belong to which plan year. A contract that covers claims incurred and paid inside the same twelve months leaves a gap for claims incurred late in the year and paid after it closes. That gap is yours.
What happens at renewal if the year goes badly? Ask directly whether the carrier can re underwrite, whether they can move you back to a fully insured quote, and whether any renewal cap exists. Get the answer before you move, not after.
When staying fully insured is the right answer
There is a version of this conversation where the correct recommendation is to do nothing. A group of thirty employees with two ongoing high cost conditions and a tight cash position is buying something valuable when it buys full risk transfer. The premium includes a margin, and that margin is the price of certainty. Certainty has a legitimate value.
The problem in the market is not that level funding is oversold as a product. It is that it is frequently sold without the settlement terms, the contract basis, and the renewal mechanics ever being explained. Those three things decide whether the arrangement works. Ask about them first, and the rest of the conversation gets much easier.
