Think about the week your renewal packet lands. Right now, your 75-person company spends $1.8 million a year on employer-paid benefits. Your team assumed a 5% increase and put an extra $90,000 in next year’s budget. Then the renewal comes in 14% higher than last year’s. That $252,000 increase pushes total spend past $2 million for next year. You’re $162,000 short, and every option left is a hard one: absorb it, change the plan, shift more cost to employees, or tighten eligibility.

If that budget cycle sounds familiar, look at where the forecast started. Last year's invoice, plus a flat percentage increase, never accounted for how these costs actually move. Medical trends, claims experience, pharmacy costs, and the assumptions built into your current rate all shape the next renewal.

82% of small business decision makers offer health insurance, and for most of them one of the largest variable lines on the budget and the hardest one to predict. The good news is it’s predictable enough to model. Here’s where to start.

By the time the packet reaches you, the market, your claims, and the plan’s pricing assumptions have already set the number. Your Finance team is reacting to a decision it never got a seat at.

Four things set that number, and each one belongs in the forecast before the packet arrives: medical trend, your own claims experience, the assumptions inside your current rate, and pharmacy and other outside cost pressure.

Medical trends give you a place to start

You may be looking at last year’s spend and wondering what percentage is realistic enough to take into the next budget cycle. PwC expects group medical costs to rise 8.5% in 2026. The Peterson-KFF Health System Tracker's 2026 small-group analysis puts the underlying trend at about 9%, and found that across 318 small-group insurers, the median proposed increase was 11%, with roughly one in 10 requesting 20% or more. All three of those small-group figures come from that one analysis. That spread gives you a practical planning range before you factor in your own claims experience, location, plan design, and carrier methodology.

Your own claims experience narrows that range

A relatively quiet year may still leave you wondering how much one high-cost event could move the renewal. The answer depends on how the plan is rated, so ask your provider to walk through the calculation using your actual arrangement. You should know how claims feed into the rate, and what an unfavorable year could mean for the forecast, before that number goes to leadership.

The current rate may be carrying assumptions that won’t repeat

A first-year number can look like a reliable baseline until the next renewal exposes what was built into it. Carrier changes, pricing concessions, utilization assumptions, and plan design decisions can all affect how the rate develops in later years. Ask which assumptions shaped the current price, how long they apply, and what the next two renewals could look like under conservative scenarios.

Market pressure keeps moving even when your workforce stays the same

Your claims can stay quiet, and the pharmacy line will still climb. Specialty medications, glucagon-like peptide-1 (GLP-1) drugs, cancer treatment, and provider rate increases all move whether or not anything changed in your workforce.

Employers are already restructuring around it. Per the Society for Human Resource Management (SHRM), 77% of employers now bundle prescription coverage into the medical plan. That’s down 16 percentage points in 2026, a drop SHRM ties to GLP-1 cost pressure. When a cost category moves enough to change how employers structure coverage around it, carrying last year’s number forward stops working. Treat pharmacy as its own line, re-price it every year, and ask your provider how your plan handles specialty and GLP-1 spend.

Plan changes create work after the rate is set. Eligibility updates, required notices, employee communication, and benefits administration all land on someone’s desk – and that work has a price. In the G&A Partners’ SMB Readiness Report, 51% of small and midsize businesses said their compliance costs have increased, 34% have paid for support of some sort to keep up, and 50% have eliminated or decreased certain benefits or perks. Build internal time and external support into the forecast so the renewal doesn't create a second unplanned cost once the rate is approved.

Member months. The total months of coverage across everyone enrolled during the year. It is a more accurate denominator than headcount when enrollment moves mid-year.

De-identified scenario. A real claims example with the employer and member details stripped out, used to show how a plan responds without exposing anyone’s data.

Percentage-point sensitivity. How many points your rate moves per dollar of additional claims. Ask for this when a provider will not share a scenario.

Once you know what can move the renewal, turn those factors into a model someone else can follow. Each pass should leave your team with a number, a source, and an assumption it can defend in front of leadership:

1. Start with the full employer-paid baseline.
   Pull every employer-paid cost into one view: premium contributions, benefits administration fees, broker or consulting fees that sit outside the premium, and any other benefits expenses. Employer contributions are part of the premium, so count that amount once. Keep the accounting basis consistent from year to year, then divide the annual total by average covered employees, or by member months when you have them. That gives you a clean starting point for every scenario that follows.

2. Put a market range around it.
   Use PwC’s 8.5% medical cost trend projection as the base planning case and Peterson-KFF’s 11% median proposed increase as the higher case. Those two figures bracket the range until claims and plan details let you narrow it.

3. Make the provider show you the stress case.
   A $200,000 claim sounds serious, but the dollar amount alone does not tell you what happens to your renewal. Ask the provider to model a high-dollar claimant, higher specialty-drug use, or an unfavorable claims year under your actual rating arrangement. Ask for the rating methodology, a de-identified scenario, or a percentage-point sensitivity. Any of the three gives you something usable, and uncertainty that remains belongs at the high end of the range.

4. Carry the range through years two and three.
   Keep market trend, company-specific experience, enrollment, and plan changes on separate lines. Use conservative assumptions and label every projection as illustrative. Leadership can work with a range when the math and the unknowns are visible.

What the range looks like on a $1.8 million baseline

Illustrative example. Use the table as a planning tool. Actual renewal depends on plan design, enrollment, employer contributions, claims activity, carrier methodology, market conditions, and eligibility.

Using the same 75-person company, the difference between the 5% budget assumption and a 14% renewal is $162,000. Present that gap to leadership before renewal season starts while there’s still time to decide how the company will absorb it.

That 14% sits well above both the market planning case and the median proposed increase. When a quote lands that far above market, ask for a line-by-line walkthrough before you build the budget around it.

Once you have a range, the next question is how the plan turns claims and market movement into your rate. Fully insured small-group coverage, large-group coverage, level-funded arrangements, self-funded plans, and professional employer organization (PEO) master plans all handle experience differently. State rules, group size, and carrier methodology change the calculation, too. Ask the provider to walk you through the method used for your plan and show where each assumption enters the rate.

A pooled master plan may spread risk across a broader population, which can reduce the weight of one participating company's experience. Eligibility depends on underwriting, risk profile, carrier terms, and plan rules. Compare the pooled option with the open-market alternatives available to your company. A group with favorable claims may receive a stronger result outside the pool, so you need the rating basis and eligibility decision for every option in writing.

Contribution strategy belongs in the same conversation. Workers at firms with 10 to 199 employees contribute 36% of family premiums, compared with 23% at large firms. That 13-point gap shows how plan economics can reach employees, especially when employer contributions or plan options change at renewal. Model the employer and employee sides together before leadership approves the budget.

Plan variety changes the budget, too. More options give employers more ways to set contributions and manage enrollment, and every option creates a different cost profile. Ask which plans your group qualifies for, how enrollment shifts affect employer spend, and what could change at renewal.

Your model now has a few open inputs left. The provider needs to fill them with numbers and methodology instead of reassurance. Ask for each answer in writing so the assumptions can travel with the budget.

1. How does claims history affect the rate?

Ask: "How does my company's claims history factor into the rate? If the plan uses a master plan pool, how does the pool change that calculation? What are the eligibility requirements, and can you provide your base rate increase history?"

A useful answer includes: A clear explanation of how the company's claims history, the broader pool, and underwriting each affect pricing. The provider should also share its base rate increase history and explain why recent years may have run higher. A larger pool may reduce the effect of a high-dollar claim for some groups. For some smaller groups, the pooled option may be less favorable than an open-market plan.

Watch for: Any suggestion that pooled pricing guarantees a lower or more stable renewal. If the provider shares increase history without explaining the drivers behind it, ask what changed and which factors would apply to your group.

2. What is driving the increase?

Ask: "What medical trend assumption are you using for my upcoming renewal? How much of the increase comes from trend, plan changes, enrollment, and company-specific experience?"

A useful answer includes: A percentage breakdown showing how each factor contributes to the renewal. You should be able to see which portion reflects the broader market and which portions come from the plan or workforce.

Use it in the forecast: Apply each percentage to the corresponding line in the model. Keeping the drivers separate makes it easier to update the forecast when enrollment, plan design, or claims information changes.

3. What happens in an unfavorable year?

Ask: "How would a high-dollar claim or an unfavorable utilization year affect renewal under this arrangement? Show me the rating methodology, a de-identified scenario, or the percentage-point sensitivity you use."

A useful answer includes: A documented example showing how the plan responds when claims run higher than expected, and which parts of the result are specific to your group.

Use it in the forecast: Compare the provider's scenario with the stress case already in the budget. Any part of the methodology the provider cannot document belongs at the high end of the range.

G&A Partners supports 130,000+ worksite employees, and that scale is what gives the PEO master plan its buying power. Pool pricing applies when a client's risk profile qualifies. Eligibility isn't guaranteed, and it depends on the same risk assessment the open market would run. G&A also moves groups off the master plan when the risk profile doesn't fit the pool. In either scenario, the decision gets made on your numbers.

Once the budget is approved, someone has to run what’s in it. G&A manages group health insurance and the ancillary and voluntary benefits that sit alongside it, administers 401(k) plans, and handles benefits administration.

While the model is still open, you'll be going back to your provider with questions. In 2025, G&A answered 88% of client service calls within 20 seconds, and 97% of clients said G&A met or exceeded expectations. When an assumption needs to be explained, challenged, or adjusted mid-renewal, you need someone who can pick up. And that’s what G&A delivers.
