Why Workers’ Compensation Benchmarking Is Critical — No Matter How You Buy Insurance

MARCH 3, 2026

An effective benchmarking tool enables you and your broker to quickly and easily compare your workers’ compensation program to those of similar organizations across key cost and structural metrics. These can include premiums and rates, program design, funding types, class codes, and experience modification factors (e-mods). USI’s tech-enabled data helps identify the specific drivers behind cost differences so you can make better risk decisions.

Guaranteed Cost or Deductible?

Guaranteed-Cost Programs: Benchmarking Protects Your Budget and Your Leverage

In a guaranteed-cost program, your cost is primarily the premium you pay for the policy term. Because the carrier absorbs the risk of loss volatility, it reflects that risk primarily in the premium it charges. Benchmarking helps you answer the questions that underwriters and internal finance leaders — such as CFOs and controllers — care about:

• Are we paying a competitive premium for our industry, payroll size, and states of operation?
• Are our rates moving in line with peers — or rising due to correctable issues? These can include classification, e-mod, and over-reserved or poorly managed claims that increase perceived loss severity.
• Are we improving relative to similar employers, or just hoping the market stays favorable?

Benchmarking gives you a clear, objective way to challenge assumptions, validate year-over-year changes, and strengthen renewal negotiations.

Deductible Programs: Benchmarking Helps Evaluate Total Cost, Not Just Fixed Premium

In deductible programs, the employer retains a layer of losses up to the deductible, while the carrier provides statutory coverage above the deductible, including claims payments and administration.

The deductible deposit premium is only part of the picture: your ultimate expense depends on loss performance within the retained deductible layer and how efficiently the carrier prices and manages losses above the deductible over time.

Benchmarking becomes even more important because it helps:

• Evaluate whether fixed costs (such as carrier charges and administrative loads) are competitive for your peer group.
• Compare your loss performance to similar employers and identify realistic improvement opportunities.
• Determine whether the program structure still aligns with your risk appetite as operations, payroll, and loss trends change.

What Are the Main Drivers You Should Benchmark?

Benchmarking is most useful when it focuses on the handful of rating inputs that move costs. It helps you see whether changes are coming from your data (payroll/classification/losses), your program structure, or carrier pricing. Here are the core drivers to track each renewal cycle:

1. Rate by class code (classification accuracy is everything). Workers’ comp rates are applied per $100 of payroll, by job classification. Two employers with similar payrolls can pay very different premiums if payroll is allocated differently across job class codes or if roles are misclassified. Benchmarking helps flag when your class mix is an outlier.
2. E‑mod: your loss experience vs. peers. Experience rating measures your actual losses against the expected losses for employers with similar job classifications. This calculation produces an e-mod that can raise, lower, or leave your premium unchanged, depending on your loss performance. Benchmarking helps you determine if your e-mod is in line with industry peers, allowing for corrective action where needed.
3. LCM (carrier margin): the multiplier that turns loss costs into your rate. In many states, carriers apply a loss-cost multiplier (LCM) to advisory loss costs to develop their filed rate. If class codes and e-mod are stable, premium shifts may still occur because the carrier’s LCM (expenses/taxes/profit provision) differs by insurer or changes over time.
4. Program structure factors (especially important in deductible programs). Guaranteed-cost programs concentrate costs into a fixed premium, while deductible/loss-sensitive structures introduce additional moving parts tied to retained losses and program charges. What to benchmark: fixed carrier/administrative charges, retained loss performance, and claims management effectiveness — so you can evaluate total program economics.
