The fastest way to lower employee health insurance costs is to increase your group purchasing power — either by joining a larger risk pool, restructuring your plan design, or shifting cost-sharing in a smarter way. Most small businesses between 20 and 100 employees overpay simply because they are buying coverage alone. The seven strategies below give you a practical roadmap, ranked from highest-impact to lowest effort, so you can stop bleeding money and start offering benefits that actually attract good people.
If you have been staring at your renewal notice wondering how premiums jumped again, you are not imagining it. According to the KFF 2024 Employer Health Benefits Survey, the average annual premium for employer-sponsored family coverage hit $25,572 — a 7% increase from the prior year. For a 20-person company, that adds up fast. And unlike a Fortune 500 company negotiating from a position of strength, most small businesses have almost no leverage with the insurers (think Aetna, United Healthcare, Cigna, Blue Cross Blue Shield).
That leverage gap is exactly why one of the most powerful solutions involves outsourcing your HR and benefits function to a Professional Employer Organization — a co-employment partner that bundles your employees into a much larger group and negotiates carrier rates that a 15- or 50-person company could never access on its own. We will break down how that works in Strategy 1, then walk through six additional tactics you can layer on top of it. These strategies work independently too, so even if you only implement two or three, you will see real savings.
Why Small Businesses Overpay for Health Insurance
Insurance carriers price risk based on group size. A company with 25 employees carries concentrated risk — one catastrophic claim can spike everyone’s premiums at renewal. Large employers spread that risk across thousands of workers, which gives them predictably lower rates. Small businesses have historically had no way to close that gap. That is changing, but only if you know which strategies to use.
Strategy 1: Join a Large Group Risk Pool Through a PEO
A Professional Employer Organization (PEO) co-employs your workforce alongside thousands of other businesses. Because your employees are technically on the PEO’s master health plan, you get large-group rates — the same pricing tier a 5,000-person company gets — even if you only have 10 employees.
According to NAPEO, businesses that use a PEO grow 7-9% faster and have 10-14% lower employee turnover than comparable businesses that do not. The benefits savings are a big reason why. In our experience matching hundreds of businesses through PEO Marketplace, employers switching to a PEO save an average of 20-30% on health insurance premiums compared to what they paid on the open small-group market.
Beyond pricing, you get access to richer plan options — HSA-compatible HDHPs, dental, vision, life, disability — that you simply cannot offer as a standalone small employer. Carriers do not offer those packages to a 12-person company. They do to a co-employer with 80,000 covered lives.
The tradeoff: you are locking your benefits into the PEO’s carrier relationships. Most good PEOs offer 3-5 plan options, but you are not building a fully custom plan. For most small businesses, that is a very acceptable trade for 20-30% savings and a dramatically better employee experience. You can explore your options by visiting our guide to the best PEOs for small businesses or using our free PEO matching tool.

Strategy 2: Switch to a High-Deductible Health Plan (HDHP) Paired with an HSA
HDHPs have lower monthly premiums in exchange for a higher deductible before insurance kicks in. The savings can be significant — KFF data shows HDHP premiums average 15-20% less than traditional PPO plans. Pair that with a Health Savings Account (HSA) and you create a tax-advantaged vehicle your employees can use to cover out-of-pocket costs.
For 2026, the IRS HSA contribution limits are $4,300 for individuals and $8,550 for families. You can contribute to your employees’ HSAs as part of your benefits package — those contributions are tax-deductible for you and tax-free for employees. Many employers fund the HSA partially to offset the higher deductible, and they still come out ahead on premium savings.
This strategy works best when your workforce is younger and generally healthy. If your team skews older or has high chronic condition rates, the HDHP math can work against you in year two at renewal.
Strategy 3: Restructure Your Employer Contribution Strategy
Most business owners set up a flat employer contribution — say, the company pays 80% of the employee-only premium. That feels generous, but it may be inefficient. Consider these adjustments:
Defined Contribution Model
Instead of covering a percentage of a specific plan, you give each employee a fixed dollar amount — say $500/month — and let them choose from multiple plan tiers. Employees who want richer coverage pay the difference. You cap your exposure. Your cost is predictable.
Tiered Contribution by Plan Choice
Contribute more toward lower-cost plans to nudge employees toward cost-efficient options. If the HDHP costs the company $400/month and the PPO costs $700/month, you might cover 100% of the HDHP but only 70% of the PPO. Employees are incentivized to make cost-conscious choices.
Strategy 4: Add a Spousal Surcharge or Coordination of Benefits Rule
This is one of the most overlooked savings levers. If an employee’s spouse has access to health insurance through their own employer but enrolls on your plan anyway, you are paying for duplicate coverage. A spousal surcharge — typically $100-$200/month — discourages this. Or implement a coordination of benefits rule that makes the spouse’s own employer plan the primary payer.
According to KFF, dependent coverage adds an average of $7,000-$8,000 per year per enrolled dependent in employer costs. Even a modest reduction in unnecessary dependent enrollment can produce meaningful savings without reducing the quality of your benefits.
Strategy 5: Introduce Voluntary Benefits to Reduce Core Plan Usage
Voluntary benefits like dental, vision, accident, critical illness, and hospital indemnity insurance are employee-paid (or low-cost employer-paid) benefits that reduce the frequency of claims hitting your main medical plan. Employees who have accident insurance, for instance, are more likely to file supplemental claims there rather than running everything through the major medical plan.
These benefits are also a recruiting tool. Even if you cannot afford to pay for them, offering employees access to group-rate voluntary benefits at no cost to you adds real value to your package. A PEO or a benefits broker with group relationships can set these up quickly.
Strategy 6: Implement a Wellness Program with Incentives
Preventive care and early intervention reduce claims. Fewer large claims mean lower premiums at renewal. The math is straightforward, even if the timeline is not immediate. A basic wellness program does not need to be expensive:
Low-Cost Wellness Tactics That Move the Needle
- Annual biometric screenings (often free through your carrier)
- Incentivized preventive visits — reward employees with an HSA contribution for completing their annual physical
- Mental health EAP (Employee Assistance Programs) — these reduce behavioral health claims dramatically and cost $15-30 per employee per year
- Tobacco-use surcharges — the ACA allows up to a 50% premium surcharge for tobacco users, which incentivizes cessation and reduces your risk pool’s overall claims
Carriers look at your claims experience when pricing renewals. A documented wellness program signals lower future risk, and some carriers will discount premiums for groups with verified wellness initiatives.
Strategy 7: Shop the Market Every Year — and Use a Broker Who Works for You
Too many employers renew with the same carrier year after year out of inertia. The health insurance market is competitive. Carriers price aggressively to win new business, then creep up rates on locked-in clients. Shopping the market at every renewal — ideally 90 days before your anniversary date — gives you real leverage.
Make sure your broker is independent and represents multiple carriers. Captive agents only sell one carrier’s products. An independent broker or a benefits advisor connected to a PEO marketplace can run a true market comparison and show you what you are actually leaving on the table.

The Bottom Line
You do not have to accept annual double-digit premium increases as a fact of life. The businesses that consistently lower employee health insurance costs are the ones that take a strategic approach — starting with purchasing power (group pooling through a PEO), then layering in smarter plan design and contribution structures. Based on our analysis of 100+ PEO providers at PEO Marketplace, Strategy 1 alone delivers more savings than most employers expect, and it also solves the HR administration burden that comes with managing benefits in-house.

Frequently Asked Questions
How much can a small business realistically save on employee health insurance in 2026?
Based on KFF benchmark data and our experience at PEO Marketplace, small businesses that switch from standalone small-group coverage to a PEO’s group plan typically save 20-30% on health insurance premiums in year one. Layering in plan design changes like an HDHP or a defined contribution model can push total savings higher, often reducing per-employee health costs by $1,500-$3,000 annually.
What is a PEO and how does it lower health insurance costs?
A Professional Employer Organization (PEO) co-employs your workforce alongside thousands of other businesses, which lets it negotiate large-group health insurance rates that a small company could never access independently. Your employees join the PEO’s master health plan, giving you pricing and plan options typically reserved for employers with hundreds or thousands of workers. You can learn more about how the matching process works at our Find Your PEO page.
Is an HDHP a good option for a small business with older employees?
HDHPs work best for younger, generally healthy workforces because employees absorb more out-of-pocket costs before insurance kicks in. If your team skews older or includes employees managing chronic conditions, the out-of-pocket exposure can create dissatisfaction and even impact retention — even if the premium savings look good on paper. Run a claims analysis with your broker before making the switch.
Can I lower health insurance costs without cutting employee benefits?
Yes — and this is the key insight most small business owners miss. Strategies like joining a PEO risk pool, restructuring contribution tiers, and adding voluntary benefits can actually improve your benefits package while reducing your costs. Employees often get access to richer plan options through a PEO than they had before, even as the employer’s total spend goes down.
How often should I shop my company’s health insurance plan?
You should put your health insurance out to market at every annual renewal, ideally starting the process 90 days before your plan anniversary date. Carriers price aggressively to win new business, and staying with the same carrier year after year without competitive bids is one of the most common reasons small businesses overpay. An independent broker or a PEO advisor can run a full market comparison for you at no cost.
