Every renewal letter arrives with a number, and most employers judge the year by it. That number is a poor scorecard. Most of it is set by things nobody at your company or ours controls. What tells you whether your plan is actually being managed well is how your costs move against trend over several years. The groups whose cost line runs below trend are what we call trend benders.
What We Mean by Trend, and by a Trend Bender
Trend is the year-over-year increase in the cost of care across the whole market: higher prices, more utilization, new and more expensive drugs. It hits every employer at once, and no broker, carrier or HR department controls it. For 2026, the Business Group on Health survey of 121 large employers projected a median trend of 9% before plan design changes, and 7.6% after. The gap between those two figures is the most misquoted distinction in this subject: the lower number already assumes the employer changed something.
A trend bender is a group whose costs rise more slowly than trend, or fall, consistently. Below trend is the definition of a win, because trend is the part of the increase everyone shares. Take it away and what is left is the part somebody actually did something about.
Why the Headline Renewal Is Not the Scorecard
The percentage in a renewal letter is mostly driven by factors outside anyone’s control, and which factors depends on your size.
- 50 or fewer employees, fully insured: your rates come from the carrier’s rate filing with the state, adjusted for your employees’ ages and location. Your own claims do not set your renewal at all. A hard claims year cannot show up in it, and a healthy one cannot earn you a reduction.
- 51 employees and above, experience rated: the carrier blends your own claims experience with its book rate. The more enrolled contracts you have, the more weight your own claims carry. At this size the level of the renewal is largely your own claims year, good or bad.
So a decrease is not automatically a broker’s achievement, and an increase is not automatically a broker’s failure. We say that plainly because it is the honest basis for the rest of this page. What a broker controls is not whether a renewal opens up or down. It is whether the number you are given is the number you accept.
The Three-Line Test
The way to judge a renewal is to put three lines side by side, always in this order:
- National trend, which sets the era. The 2026 figures above, and the most recent KFF Employer Health Benefits Survey, which put 2025 family premiums up 6% and single up 5%.
- Local trend, which sets the market. Michigan publishes this: the Department of Insurance and Financial Services approved an average 11.1% increase for the 2026 small group market, and carriers filed an average of 9.6% for 2027.
- Your own renewal, which is the verdict. It means nothing without the two lines above it.
Two cautions about the local line. First, the Michigan filings cover fully insured groups of 50 or fewer only. Large group rates are not filed with the state, and the state has no authority over self-funded rates. For a larger group the local figure is context, not a comparator. Second, the statewide average blends HMO and PPO carriers. For 2027, separating them gives roughly 11.1% for the HMO side and 7.9% for the PPO side, against the 9.6% blend, so quoting the blended figure makes an HMO group’s renewal look worse than its market was and a PPO group’s look better. We recompute that split every year, because in 2026 there was no gap at all.
What Actually Bends the Line
The levers fall into two groups, and they should never be rolled into one “savings” number, because they are different kinds of result.
Rate Benders: Changing What the Coverage Costs
- At 50 employees or fewer, the lever is the carrier. Small group rates are filed with and approved by the state, so the incumbent carrier usually has no better number to give you at renewal, and negotiating with it wastes the renewal window. The lever is moving to a carrier whose filed rates are lower for your age mix, area and product type. For 2027, Michigan small group filings range from about 7% to about 15% depending on the carrier, and for a small employer that spread is the opportunity.
- At 51 and above, the lever is a plan-replicating market test. We quote the same plan designs with other carriers and put those quotes in front of the incumbent. Typically the incumbent matches or beats them, and at larger sizes it will often concede a credit even when it will not move the rate. The word that matters is replicating: a quote that changes the plan design is a buy-down, not a comparison, and it proves nothing about price.
Cost Benders: Changing What the Employer Pays
- Plan design: deductibles, networks, and pairing a high-deductible plan with an HSA contribution.
- Contribution strategy: how the employer share is split across employee and dependent tiers, which often moves total cost more than any plan change.
- Funding: level funding or self-funding, where lower claims come back to the employer instead of staying with the carrier.
- Pharmacy terms, for groups large enough to control them.
Both kinds are legitimate. But a design change that shifts cost onto employees is not the same win as a carrier conceding a credit on an identical plan. We report them separately.
Trend Bending by Company Size
What drives your renewal, which trend line you should compare it against, and which levers can bend it all change with the size of the group. The thresholds below are by employees, but carriers weight your own claims by enrolled contracts, so a 300-employee company where half the staff waive coverage behaves more like a smaller group than its headcount suggests.
| 2–50 | 51–249 | 250–999 | 1,000+ | |
|---|---|---|---|---|
| What sets the renewal | The carrier’s state-filed rates, your employees’ ages and location | A blend of the carrier’s book rate and your own claims, weighted toward the book at the smaller end | Your own claims and the book rate in roughly comparable measure | Mostly your own claims year |
| Right trend comparator | Michigan’s filed small group figure for your product type (HMO or PPO) | National employer trend before plan changes; the Michigan filing is context only | National employer trend, plus stop-loss trend if self-funded | Your own cost per member over time, with national trend as background |
| Main rate bender | Moving to a carrier whose filing is lower | A plan-replicating market test; a credit if the rate will not move | Funding structure and contract terms, not shopping alone | Contract terms: pharmacy, stop-loss, network and administration |
| Main cost benders | Plan design, contribution strategy, defined contribution | Plan design, contribution strategy, level funding | Self-funding or level funding, pharmacy carve-out, plan design | Plan design, pharmacy management, site of care, participation |
| What a trend bender looks like | Renewals at or below the filed average for your product type, year after year | A series below national trend, with the gap between opening ask and final rate documented | Claims cost per member growing more slowly than national trend over several years | Your own per-member cost bending below its own history and below national trend |
2 to 50 Employees: The Book Sets the Rate, So the Lever Is Which Book
At this size your renewal is not a verdict on your employees’ health. Rates are set from the carrier’s state filing, adjusted for age and area, and your own claims do not enter into it. That cuts both ways: a hard claims year cannot raise your rates, and a healthy one cannot lower them.
Because the incumbent is bound by its filing, it usually has no better number to give you. The rate lever is moving to a carrier whose filed rates are lower for your age mix, location and product type. For 2027 those filings range from about 7% to about 15% by carrier, and for a small group that spread is the opportunity. The right comparator is the filed average for your product type, not the blended statewide figure, because HMO and PPO filings can differ by several points.
The cost benders at this size are plan design, how the employer contribution is split between employee and dependent tiers, and defined contribution through a QSEHRA or ICHRA, which caps the employer’s cost at a set amount. A small group bends its line by landing in the right filing every year and structuring contributions deliberately. See our page for companies with 2 to 50 employees.
51 to 249 Employees: The Number Becomes Negotiable
Crossing 50 employees moves you into the large group market, where carriers no longer file rates with the state and instead price your group as a blend of their book rate and your own claims. How much weight your own claims get depends on how many contracts are enrolled. At the lower end of this band the book still dominates, so a single bad claims year moves your renewal less than people assume, and a single good year earns you less credit than you might hope.
What changes is that the carrier is now pricing a judgement, and a judgement can be revisited. The rate lever is a plan-replicating market test: we quote the same plan designs with other carriers and put those quotes in front of the incumbent. Typically it matches or beats them, and groups of this size can often secure a credit even when the carrier will not move the rate itself. The honest record of that work is the gap between the carrier’s opening ask and the number you finally accept.
The Michigan filed average no longer applies to you, because large group rates are not filed. Compare instead against national employer trend before plan changes, which the Business Group on Health put at 9% for 2026, and treat the Michigan figure as context. Level funding also becomes realistic in this band, which gives you claims data for the first time and a way to keep part of a good year. See our page for companies with 51 to 249 employees.
250 to 999 Employees: Shopping Alone Stops Being the Answer
At this size your own claims and the carrier’s book carry roughly comparable weight, so half the movement in your renewal is yours and half is not. A single blended percentage cannot be argued with, because nobody can tell which half moved. The real work is taking the renewal apart: claims experience, trend, large claims above the pooling point, and administrative charges, each tested separately.
Market tests still matter, but their limits show. A competing carrier underwrites the same claims history, so the cost driver moves with you to the next carrier. The levers that bend the line here are structural: whether to self-fund or level-fund, how stop-loss is written, whether pharmacy is carved out under its own contract, and plan design aimed at where your claims actually are.
If you are self-funded, add stop-loss to the three lines. Because the stop-loss deductible stays fixed while the large claims above it grow, stop-loss premiums tend to rise faster than overall claims trend, a pattern known as leveraged trend. A group can hold its claims growth below national trend and still see its total cost rise faster if the stop-loss renewal is not managed. See our page for companies with 250 to 999 employees.
1,000 or More Employees: Your Renewal Is Your Own Year, Priced
Above about a thousand enrolled contracts a group is generally treated as fully credible: the renewal reflects your own claims almost entirely. At this size the most quoted number in the industry, national trend, is evidence about somebody else. The real comparison is your own cost per member over several years, set against your own history, with national trend as background.
The levers are contractual and operational rather than market-driven. Pharmacy contract terms, stop-loss structure, network and site-of-care strategy, and plan design aimed at specific cost drivers all bend the line. So does participation: credibility is bought by enrollment, not headcount, and low take-up costs twice, once in a smaller credible base and again in the adverse selection that tends to come with it. A large employer is a trend bender when its per-member cost grows more slowly than its own past and more slowly than the market, across several years. See our page for companies with 1,000 or more employees.
Two Recent Examples
These are two of our clients from the current renewal cycle, described without names. They are two documented cases, not a benchmark, and each comes with the caveat that matters.
An Automotive Supplier: From Double-Digit Asks to Two Decreases
| Renewal | Carrier-Stated Change |
|---|---|
| January 2023 | +11.98% |
| January 2024 | +10.91% |
| January 2026 | −3.40% |
| January 2027 | −4.43% |
After years of double-digit renewals, this experience-rated group took two consecutive decreases at a time when national trend was running around 9%. The honest caveat: the change from increases to decreases coincides with a move to a different carrier. Part of the result is the carrier change and part is the group’s own claims, and from the outside those cannot be cleanly separated. Moving carriers when the market offers a better arrangement is itself one of the levers above, but we would not present this series as proof of anything on its own.
A Hospitality Employer: A Decrease Confirmed by Testing It
This group received a 5.45% decrease on its October 2026 renewal, with the same carrier and the same plan designs as the year before. That matters: with no carrier change and no design change, the comparison means exactly what it appears to mean. It is also notable because the carrier raised its pooling points for 2026, which tends to push experience-rated renewals up, not down.
The honest caveat runs the other way here. An experience-rated decrease reflects the group’s own claims year, and we did not create it. What we did was treat the number like any other: we took the account to market anyway, priced the alternatives, and held the plan design constant so the comparison stayed like for like. The incumbent’s opening number already beat what the market offered, so the group stayed where it was. That is a legitimate outcome of a market test. It validated the renewal rather than improving it.
Not every group bends the line in a given year. In the same cycle, other groups we work with received increases. Which is exactly why one year is not the measure.
Why One Good Year Proves Nothing
A single renewal below trend may simply be a healthy claims year. That is good news for the employer, but it is not evidence that anything was managed well, and anyone selling it that way is taking credit for the weather.
What counts is a series: at least three consecutive renewals set against the trend for those same years. A group that stays below trend across several cycles, through good claims years and bad, is bending its line. The same logic applies to any firm claiming to deliver results. A single client below trend proves nothing; many clients below trend across many years is a real claim, because the market-wide part is identical for everyone and the noise averages out.
How to Tell Whether Your Group Is a Trend Bender
- Gather your last three renewals, or more if you have them: the carrier’s stated percentage each year, and the rate exhibits if you can get them.
- Separate the rate change from the enrollment change. A total premium that rose 21% can be a much smaller rate increase once you account for employees added and plans introduced. Compare each year on a constant-census basis.
- Note every carrier change and plan design change, because either one breaks the like-for-like comparison for that year.
- Set each year against national and local trend for the same year, using the right local line for your size and funding.
- Ask what happened after each opening number. Was it tested against a replicating quote? Did the carrier move, or offer a credit? The distance between the opening ask and what you finally paid is the part that reflects management, not weather.
How We Help
Send us your last few renewals and we will lay out the three lines for your group: national trend, local trend and your own renewals, adjusted for enrollment and flagged for carrier and design changes. That tells you honestly whether your line is bending and why.
At renewal, the work is the part we control: testing the carrier’s number against plan-replicating quotes, asking for the credit when the rate will not move, holding design constant so the comparison means something, and placing new group coverage when another carrier is genuinely the better arrangement.

Frequently Asked Questions
What is a trend bender?
A trend bender is an employer whose health plan costs rise more slowly than market trend, or fall, consistently over several renewals. Trend is the year-over-year increase in the cost of care that affects every employer at once. Because nobody controls it, performing below it is the meaningful measure of a well-managed plan. We use the term for groups whose cost line has bent below trend over time, not for a single good year.
What is the health care cost trend for 2026?
The Business Group on Health survey of 121 large employers projected a median 9% increase in health care costs for 2026 before plan design changes, and 7.6% after. In Michigan, the Department of Insurance and Financial Services approved an average 11.1% increase for the 2026 small group market, and carriers filed an average of 9.6% for 2027. Always check whether a trend figure is before or after plan changes; the difference is usually more than a point.
Does the right trend comparison change with company size?
Yes. For a fully insured group of 50 or fewer, compare against the Michigan filed small group average for your product type, because your rates come from that filing. From 51 to 249, rates are not filed, so compare against national employer trend before plan changes and treat the Michigan figure as context. From 250 to 999, use national employer trend, and add stop-loss trend if you are self-funded. At 1,000 or more, the most useful comparison is your own cost per member over several years, with national trend as background.
Does a renewal decrease mean our broker did a good job?
Not by itself. For groups of 50 or fewer, rates come from the carrier’s state filing and your own claims do not set your renewal. For larger groups, the level of the renewal largely reflects your own claims year. What a broker controls is what happens after the carrier states its number: whether it is tested against plan-replicating quotes, whether the carrier moves or offers a credit, and whether plan design is held constant so the comparison is honest. Judge the gap between the opening ask and the final number, over several years.
Why can’t a small group negotiate its renewal down?
Because in Michigan small group rates are filed with and approved by the state. The incumbent carrier generally does not have a lower number to give you at renewal. The lever for a group of 50 or fewer is moving to a carrier whose filed rates are lower for your age mix, location and product type. For 2027, Michigan small group filings range from about 7% to about 15% by carrier.
How many years of renewals do we need to know if we are bending trend?
At least three consecutive renewals, set against national and local trend for the same years. One year below trend can simply be a healthy claims year. A series shows whether the line is actually bending. Adjust each year for enrollment changes, and note any year with a carrier change or plan design change, because those break the like-for-like comparison.
Is the Michigan average rate increase the right comparison for our group?
Only if you are fully insured with 50 or fewer employees. The state’s filed rates cover that market only; large group rates are not filed, and the state has no authority over self-funded rates. Even then, use the figure for your product type: for 2027, separating HMO and PPO carriers gives roughly 11.1% and 7.9% against the 9.6% blended average.
