Health Plan Benchmarking: How Mid-Size Employers Can Compare Benefits Costs to Industry Standards

Most mid-size employers renew their health plan every year without knowing whether their rates are competitive. The broker sends a renewal letter, the employer sees a percentage increase, and the conversation centers on whether to absorb the increase, shift more cost to employees, or change plan design. What almost never happens is a systematic comparison of the employer's total benefits cost against industry benchmarks to determine whether the renewal rate is fair in the first place. Health plan benchmarking is the process of comparing your company's benefits costs, plan design, and utilization patterns against comparable employers in your industry, region, and size bracket. It answers a simple question: are we paying what we should be paying, or are we overpaying? For mid-size employers with 20 to 250 employees, the answer is frequently the latter. KFF's 2025 Employer Health Benefits Survey found that mid-size employers pay 8-15% more per employee for equivalent coverage compared to employers who actively benchmark and negotiate based on market data. That premium represents real money. A 75-person company spending $600,000 annually on health coverage that is 10% above benchmark is overpaying by $60,000 per year. Over a 3-year renewal cycle, that is $180,000 in unnecessary spending that could fund salary increases, additional benefits, or business growth. Yet fewer than 20% of mid-size employers conduct any form of systematic benchmarking before their annual renewal.

What Health Plan Benchmarking Actually Measures

Dimension 1: Per-Employee Premium Cost

The most straightforward benchmark is total premium cost per employee per month (PEPM). According to KFF's 2025 survey, the national average for employer-sponsored single coverage is $715/month ($8,580/year), and family coverage averages $2,070/month ($24,840/year). These figures vary significantly by region, industry, and employer size:

Factor	Below Average	Average	Above Average
Single PEPM	Under $620	$620-$810	Over $810
Family PEPM	Under $1,800	$1,800-$2,350	Over $2,350
Southeast Region	8-12% below national avg	National average	N/A
Northeast Region	N/A	National average	5-15% above national avg
Technology Industry	N/A	5-8% above national avg	10-18% above (richer plans)
Construction/Trade	5-10% below national avg	National average	N/A

If your 50-person company in Atlanta is paying $780/month PEPM for single coverage, you are at the high end of the Southeast average and above the national median. That does not automatically mean you are overpaying -- your workforce demographics and claims history matter -- but it is a signal that warrants deeper analysis.

Dimension 2: Employer Contribution Percentage

How much of the premium the employer pays versus the employee is a critical benchmark. The national average employer contribution is 83% for single coverage and 73% for family coverage. If you are contributing 90% for single coverage, you are generous relative to peers. If you are contributing 65% for family coverage, you are below average and may face retention pressure. Contribution strategy should align with your market position. Companies in tight labor markets (tech, healthcare, professional services) tend to contribute more aggressively. Companies in industries with more available labor (retail, hospitality, some construction trades) may contribute less without retention consequences.

Dimension 3: Plan Design Comparison

Two plans with the same premium can deliver very different value. A $700/month plan with a $1,500 deductible and 80/20 coinsurance is materially different from a $700/month plan with a $3,000 deductible and 70/30 coinsurance. Benchmarking plan design means comparing:

• In-network deductible: National average for single coverage is $1,650-$1,850.
• Coinsurance split: Most common is 80/20 (plan pays 80%, employee pays 20%).
• Out-of-pocket maximum: National average is $4,500-$5,500 for single coverage.
• Primary care copay: Most common is $25-$40 per visit.
• Specialist copay: Most common is $50-$75 per visit.
• Generic Rx copay: Most common is $10-$20 per prescription.

If your plan has a $2,500 deductible at a premium above the national average, you are paying more for less coverage. That is a clear signal to negotiate or explore alternatives.

Dimension 4: Network Quality and Access

A cheaper plan with a narrow network may not actually save money if employees cannot access their preferred providers. Benchmarking should include network breadth (percentage of local providers in-network), hospital access (major facilities included), and specialist availability. In some regions, narrow networks save 15-25% on premiums but generate employee dissatisfaction and out-of-network surprise bills that erode savings.

Dimension 5: Utilization Rates

High utilization is not inherently bad -- it can indicate employees are using preventive care, which reduces long-term costs. Low utilization can indicate employees are avoiding care due to cost barriers, which leads to expensive emergency interventions later. Benchmarking your plan's utilization rates against industry norms helps identify whether your plan design is driving appropriate behavior. Average utilization benchmarks for mid-size employers: preventive care visits at 65-75% of eligible employees annually, specialist referrals at 25-35%, emergency department use at 15-20%, and pharmacy utilization at 70-85%.

Where to Find Benchmarking Data

Free Public Sources

Several organizations publish comprehensive benchmarking data that mid-size employers can access at no cost:

• Kaiser Family Foundation (KFF): Annual Employer Health Benefits Survey with detailed breakdowns by employer size, region, industry, and plan type. The most widely cited source for health plan benchmarking.
• Bureau of Labor Statistics (BLS): Employer Costs for Employee Compensation report includes health benefit costs by industry and occupation group.
• SHRM: Annual Employee Benefits Survey covers benefit offerings, contribution rates, and plan design across employer sizes.
• Medical Expenditure Panel Survey (MEPS): Federal survey with detailed health plan cost and utilization data segmented by employer size and demographics.

Paid Benchmarking Services

For more granular comparisons, paid services provide deeper analysis:

• Mercer National Survey of Employer-Sponsored Health Plans: Detailed data by region, industry, and employer size. Subscription-based but considered the gold standard for benefits benchmarking.
• Benefits consulting firms: Most large consulting firms (Aon, Willis Towers Watson, Gallagher) publish annual benchmarking reports that their clients can access.
• Carrier-provided data: Your health plan carrier can provide anonymized claims benchmarking showing how your group's utilization and cost compare to similar-size groups in your region.

PEO Benchmarking Advantages

PEOs have a built-in benchmarking advantage: they manage benefits for hundreds or thousands of employers simultaneously, which generates continuous, real-time market data. When your PEO tells you that your plan's per-employee cost is in the 75th percentile for companies your size in your industry, that data comes from actual employer comparisons, not survey samples. A PEO like BENEFITRA can provide benchmarking reports showing how your benefits costs, plan design, and utilization compare to similar employers within the PEO's book of business. This internal benchmarking is more precise than public survey data because it compares actual plan costs rather than self-reported averages.

The Benchmarking Process: A 4-Week Timeline

Week 1: Gather Your Data

Collect your current plan's Summary of Benefits and Coverage (SBC), your most recent renewal letter with premium rates, your claims experience report (available from your carrier or broker), your census data (employee ages, zip codes, coverage tiers), and your current employer contribution schedule. This data forms the foundation of any meaningful comparison.

Week 2: Run the Comparisons

Compare your data against public benchmarks (KFF, BLS, SHRM) for employer size, region, and industry. Identify where you fall relative to the 25th, 50th, and 75th percentiles on each dimension: premium cost, contribution percentage, deductible, coinsurance, and out-of-pocket maximum. Flag any dimension where you are above the 75th percentile -- these are areas of potential overspend.

Week 3: Explore Alternatives

If benchmarking reveals overspend in one or more dimensions, request alternative quotes. Options include different carriers offering similar plan design at lower rates, the same carrier with revised plan design (higher deductible, adjusted coinsurance) that brings cost in line with benchmarks, level-funded or self-funded arrangements that may reduce cost for groups with favorable claims experience, and PEO-pooled plans that leverage larger risk pools for better rates.

Week 4: Negotiate and Decide

Armed with benchmarking data and alternative quotes, negotiate with your current carrier or broker. Carriers are significantly more willing to adjust rates when they know you have market data showing their renewal is above benchmark. The phrase "our benchmarking shows this renewal is in the 80th percentile for our size and industry" carries more weight than "this increase seems too high."

Common Benchmarking Mistakes to Avoid

Comparing Premium Only Without Plan Design

A plan that costs 10% less but has a deductible that is $1,000 higher is not necessarily a better deal. Total cost of coverage -- premiums plus expected out-of-pocket costs -- is the correct comparison. Two plans should be evaluated on the total expected cost to both the employer and the average employee, not just the employer's premium share.

Using National Averages for Regional Markets

Health plan costs vary dramatically by geography. Comparing your costs in New York City against national averages will make every plan look expensive. Comparing your costs in rural Georgia against national averages will make every plan look cheap. Always use regional benchmarks when available.

Ignoring Workforce Demographics

A company with an average employee age of 52 will naturally have higher premiums than a company with an average age of 32, even with identical plan design. Demographic-adjusted benchmarks are more useful than raw averages. If your carrier or PEO can provide age-adjusted comparisons, use those instead of unadjusted national data.

Benchmarking Once Instead of Annually

The benefits market shifts every year. A plan that was at the 50th percentile two years ago may have drifted to the 70th percentile due to above-market renewals. Annual benchmarking creates a trend line that reveals whether your plan is becoming more or less competitive over time. Companies that benchmark annually for 3+ years reduce their cost trend by 2-4 percentage points compared to companies that benchmark sporadically.

Real-World Impact: Benchmarking Saves a Growing Company $72,000

Company: Marketing agency, 85 employees, headquartered in Charlotte, NC with remote workers in 4 states Before benchmarking: The company had renewed with the same carrier for 5 consecutive years. Annual renewals averaged 8-11% increases. Current PEPM cost: $760 single / $2,180 family. Plan design: $2,000 deductible, 80/20 coinsurance, $5,000 OOP max. Employer contribution: 80% single, 65% family. Total annual benefits spend: $612,000. Benchmarking findings: KFF data showed the company's PEPM was in the 72nd percentile for the Southeast region and mid-size employer segment. Plan design was average (50th percentile), but premium cost was significantly above average for that design. The employer contribution for family coverage (65%) was below the national average (73%), creating retention risk. Claims experience was favorable (below average utilization), suggesting the carrier was not adequately crediting the company's good experience. Actions taken: Armed with benchmarking data, the company requested quotes from 3 alternative carriers and explored PEO-pooled options through BENEFITRA. The current carrier, upon seeing competitive quotes, offered a 6% rate reduction (rather than the proposed 9% increase). The company also moved family contribution to 70% and shifted savings from the rate reduction into enhanced dental and vision benefits. Results: Annual savings: $72,000 (rate reduction + avoided increase). Improved family contribution reduced attrition risk. Enhanced voluntary benefits improved employee satisfaction scores. Net impact: the company went from a 72nd percentile cost position to a 48th percentile position while improving benefits quality.

Frequently Asked Questions

How often should we benchmark our health plan?

Annually, starting 90-120 days before your renewal date. This gives you enough time to analyze data, request alternative quotes if needed, and negotiate with your current carrier. Companies that benchmark annually maintain tighter cost control than those who benchmark only when a renewal surprise forces their hand.

Can we do benchmarking ourselves or do we need a consultant?

Basic benchmarking using KFF and BLS data is accessible to any employer. For more sophisticated analysis that accounts for demographics, claims experience, and plan design nuances, a benefits consultant or PEO can provide deeper insights. The cost of professional benchmarking ($2,000-$5,000 for a mid-size employer) typically pays for itself many times over in renewal savings.

What if our benchmarking shows we are below average cost?

Below-average cost is not always good news. It may indicate that your plan design is too lean (high deductibles, narrow network) and employees are dissatisfied with coverage quality. Benchmarking should evaluate both cost and value. If your plan is cheap but employees are not using it because the deductible is too high, you are spending money on a benefit that is not achieving its retention or wellness goals.

Does benchmarking data account for different funding models?

Most public benchmarking data (KFF, BLS) reports on fully funded plans. If your company uses a level-funded or self-funded arrangement, direct premium comparisons may not be appropriate. Instead, benchmark your total cost of risk (premiums or expected claims + admin fees + stop-loss) against equivalent metrics from surveys that include alternative funding models, such as Mercer's national survey.

How does a PEO help with ongoing benchmarking?

PEOs conduct continuous benchmarking as part of their business model. Because they manage benefits for many employers simultaneously, they generate real-time market data showing cost trends by industry, size, and region. Your PEO should provide annual benchmarking reports comparing your plan's performance to the PEO's broader book of business, giving you data-driven leverage for plan optimization.

Will my carrier know I am benchmarking against competitors?

Carriers expect employers to compare rates before renewal. Demonstrating that you have benchmarking data and competitive quotes is standard practice and signals that you are an informed buyer. Carriers are more likely to offer competitive renewals to employers they know will shop around. The goal is not adversarial -- it is ensuring that you receive fair market pricing for the coverage you need.
