How to Read Your Business Health Insurance Renewal

Last updated: May 25, 2026

Your renewal packet arrives in your inbox or on your desk, usually 60 to 90 days before your plan anniversary date. If you're like most small business owners, you flip to the page with the big number, see a percentage you don't love, and close it.

That's understandable, renewal packets are not written for you. They're written by carrier compliance teams with enough jargon to make most people give up before they find what actually matters.

This guide walks you through what's actually in a renewal letter, what each section means, and what you should be looking at beyond the headline rate.

What comes in a renewal packet

Renewal packets vary by carrier, but they almost always include the same core components. Here's what you're looking at:

The rate action letter. This is the top-level document. It states your current premium rates, your new rates for the renewal period, and the percentage change. It also includes your renewal effective date (the first day of your new plan year) and a deadline by which you need to confirm your decision, usually 30 to 45 days before the effective date.

Plan design summary (current vs. renewed). This shows what your plan will look like after renewal. Carriers sometimes make changes here quietly — adjusting deductibles, shifting copay amounts, or tweaking out-of-pocket maximums — without flagging them prominently. More on this below.

Employee contribution summary. A breakdown of the premium split between employer and employee, often presented as monthly per-person costs at each tier: employee only, employee plus spouse, employee plus children, family.

Drug formulary notice (if applicable). If your carrier has moved drugs between tiers, added prior authorization requirements, or removed drugs from coverage, this notice is often buried at the back or attached separately. It's worth reading, especially if you have employees on specialty or brand-name medications.

Network adequacy notice (if applicable). Many states require carriers to notify groups when their provider networks change materially. This notice doesn't always make it easy to tell what actually changed.

You may also receive a Summary of Benefits and Coverage (SBC), which is a standardized federal document comparing your plan's cost-sharing structure in plain terms. It's one of the more readable parts of the packet.

What 5%, 10%, and 15%+ actually means

Small group health insurance rates have averaged roughly 7 to 10% annual increases over the past several years. The KFF 2025 Employer Health Benefits Survey found that average family premiums for small firms (10 to 199 workers) climbed to $26,054 in 2025, up from $16,977 in 2020. That's a roughly 53% increase in five years, or just over 8% compounded annually.

An increase in that 7 to 10% range is, unfortunately, the new normal. It's painful, but it's where the market has been running. A great broker may be able to negotiate or find a solution that keeps you below the trend line.

Increases in the 10 to 15% range are worth scrutinizing. They may reflect normal variation in your carrier's book of business, or they may signal that you're overdue to shop the group.

Increases above 15% are uncommon in the small group community-rated market and are worth asking about specifically. A real HR administrator in an r/humanresources thread shared this experience: their 56-person group received an initial renewal quote of 13.5%, attributed to a 68% loss ratio over the renewal period and rising medical trend. They were able to negotiate down to 8 to 9% through their broker. That kind of gap between initial offer and final number happens more often than most small business owners know.

Why the rate went up (and why it's probably not about your employees)

This is the part that trips most people up.

In the small group market (generally 1 to 50 employees, though some states define it as 1 to 100), most carriers are required to use community rating under ACA rules. That means your premium increase is driven primarily by the carrier's overall book of business, not by your group's specific claims.

Your employees' doctor visits, prescriptions, and procedures in the prior year are not the reason your rate went up. The carrier pools small groups together and applies rates filed with your state's Department of Insurance or its equivalent regulator. Once the state approves the filing, every group on that carrier's book renews at the approved rate, regardless of how their specific group performed.

Most state insurance departments publish approved rate filings online, and you (or your broker) can look up what your carrier requested and what was approved. The federal CMS Rate Review portal (ratereview.healthcare.gov) also tracks filings across states for increases of 10% or more.

Two factors do influence your individual group's rate within community rating:

Demographic creep. Rates are set by the age composition of your enrolled group. Under the ACA, carriers can charge their oldest enrollees up to three times what they charge their youngest (the 3:1 age band ratio). As your team ages, even by a year or two, your age-banded premium can shift upward. If you've had low turnover and the same employees for three or four years, this may be adding a few points to your renewal.

Geographic rating area. Rates vary by where your employees live and work. If you've expanded to a new location or have employees in a higher-cost rating area, that can shift your group's blended rate.

Tobacco use (in most states). The ACA permits carriers to charge tobacco users up to 50% more than non-users in the individual market, and some states allow a tobacco surcharge in the small group market as well. If your group's tobacco-use profile has shifted, it could contribute to the renewal change.

Neither of these is your fault. Understanding them matters because it shapes what questions to ask your broker.

What to look at beyond the headline rate

The percentage increase is not the only number that matters. Carriers sometimes use plan design adjustments to dampen the headline rate while shifting costs elsewhere.

Deductible movement. Check whether your deductible increased. A plan with a 10% premium increase and a deductible that went from $1,500 to $2,000 is more expensive for employees than a plan with a 12% premium increase and a stable deductible. The IRS adjusts minimum deductibles for High-Deductible Health Plans annually, so HSA-eligible plans will always see some movement. For standard HMO and PPO plans, deductible changes are a carrier choice.

Out-of-pocket maximum changes. The ACA sets federal caps on out-of-pocket maximums ($9,200 for single, $18,400 for family in 2026), but carriers can set them lower. If your plan's out-of-pocket maximum increased at renewal, employees bear more financial risk in a bad claims year.

Copay and coinsurance changes. Specialist copays, urgent care copays, and coinsurance percentages on services can shift without flagging prominently in the rate letter. Compare the plan design summary page to last year's SBC.

Formulary and drug tier changes. If you have employees on ongoing prescriptions, a tier shift can mean a significant cost increase even when the premium stays stable. A drug moving from Tier 2 ($30 copay) to Tier 3 ($70 copay) is a $480 annual cost increase that doesn't show up anywhere in the headline renewal number.

Network changes. Carriers across the country have been narrowing networks as a cost-containment tool. If your carrier's network adequacy notice indicates that certain hospital systems or specialist groups were removed, that matters to your employees who use those providers.

What to ask your broker

A good broker should be walking through your renewal with you, not just forwarding the packet. If you're not getting a proactive conversation, here are the questions worth asking:

• What drove the rate change, and is this consistent with what other groups on this carrier are seeing?

• Did the plan design change at renewal, and if so, what changed?

• What is my carrier's approved rate filing for this period?

• Are there alternate plan options within my current carrier that would hold my cost flat by shifting some cost-sharing to employees?

• At this renewal level, does it make sense to get comparison quotes from other structures?

• When did you last shop this group to the full market?

That last question matters. HR administrators and benefits managers in smaller organizations report that their brokers don't always bring alternate quotes without being asked. One HR commenter put it bluntly: "It's a pretty barren wasteland for a business under 100 employees." The landscape isn't actually barren — there are real structural alternatives, from SHOP exchanges to ICHRAs to level-funded plans — but you won't see those options unless you ask.

Is your contribution structure still working?

Renewal is the right time to look at your contribution design, not just the premium.

Most small businesses set their employer contribution as a fixed dollar amount or as a percentage of the employee-only premium. These are the two most common structures, and they behave differently as premiums rise.

A percentage-of-premium contribution (say, 80% of the employee-only rate) means your dollar outlay goes up automatically every renewal as the premium increases. Your contribution scales with the carrier's rate action whether you intended that or not.

A fixed dollar contribution keeps your cost predictable but shifts more burden to employees over time as premiums rise faster than wages.

Neither structure is universally right. The question is whether your current split is still achieving what you intended when you set it. A few things to check:

Employee take-up rate. If participation in your plan has dropped since you last set contribution levels, that's often a sign the employee net cost crossed a threshold where some employees opted out. Lower participation creates its own problem: if your group's enrollment shrinks, you may fall below your carrier's minimum participation requirement at next renewal.

Dependent cost. Carriers set employee and dependent rates separately, and most employers pay far more toward employee-only coverage than toward family or dependent coverage. The KFF 2025 survey found workers nationally contribute an average of $6,850 per year toward family coverage. If your contribution doesn't extend meaningfully to dependents, employees with families are carrying a disproportionate share of the cost, which affects retention differently than it affects single employees.

Renewal is a good time to run these numbers with your broker; not to redesign everything, but to make sure your structure is still producing the participation and retention results you're paying for.

When to accept the renewal versus when to shop

A few honest signals that you should accept the renewal without shopping:

• Your increase is in line with the national market (roughly 7 to 8%)

• You're on a carrier your employees value and have used

• Your broker shopped the group within the last 24 months and found it to be competitively priced

Signals that you should shop before deciding:

• Your increase is 9% or above

• You've never shopped the group against other structures (SHOP, ICHRA, level-funded, PEO)

• Your broker hasn't proactively presented alternate quotes alongside the renewal

• You've added or lost significant headcount since your last market review

• Your team has shifted meaningfully in age or geography

Shopping a renewal properly typically takes three to four weeks. With Corridor, we can typically complete a full review in 48 hours.

A renewal letter is a starting point, not a final answer. The number on page one is what your carrier wants you to pay. Whether that's the right number for your group depends on questions that a single-page rate action document can't answer for you.
