In Michigan, workers' compensation premiums usually represent 0.5% to 2.5% of a company's gross sales, depending on industry risk, payroll size, and claim history. Small firms in low‑hazard sectors often fall near the lower end, while high‑risk manufacturers or construction firms can see rates closer to the upper bound.

What Is Workers' Compensation?
Workers' compensation is a state‑mandated insurance program that provides medical benefits and wage replacement to employees who suffer work‑related injuries or illnesses. In Michigan, the program is administered by the Department of Labor and Economic Opportunity (LEO) and funded through employer‑paid premiums.
How Premiums Are Calculated
Michigan uses an experience‑rating system. Premiums are calculated by multiplying three key components:
- Rate per $100 of payroll – set by the state based on industry classification (NAICS code).
- Payroll exposure – the total taxable wages paid to covered employees.
- Experience modifier – a factor that reflects the employer's past claim history (values < 1.0 lower costs, > 1.0 raise them).
The resulting dollar amount is then expressed as a percentage of total sales for budgeting purposes.
Typical Percentage Ranges by Industry
| Industry (NAICS) | Typical Premium % of Sales | Why It Varies |
|---|---|---|
| Professional Services (e.g., legal, accounting) | 0.5 % – 0.8 % | Low injury risk, minimal manual labor. |
| Retail (general stores) | 0.8 % – 1.2 % | Moderate risk from slips, trips, and handling. |
| Construction | 1.5 % – 2.5 % | High exposure to falls, equipment accidents. |
| Manufacturing (metal, plastics) | 1.2 % – 2.0 % | Machinery hazards and repetitive strain. |
Factors That Shift the Percentage
Claim History
A company with frequent or severe claims sees its experience modifier rise, pushing the premium closer to the upper end of the range.
Payroll Size
Larger payrolls dilute the per‑employee cost, often resulting in a lower % of sales, even if the absolute premium is high.
Safety Programs
Investing in safety training, ergonomic assessments, and injury‑prevention initiatives can lower the experience modifier over time.
How to Benchmark Your Business
1. Identify your NAICS code and locate the state‑published rate per $100 of payroll.2. Calculate your total taxable payroll for the rating period.3. Apply your experience modifier (provided on your annual statement).4. Divide the resulting premium by your gross sales to get the % of sales figure.
Practical Budgeting Tips
- Allocate a contingency buffer of at least 0.5 % of sales for unexpected claim spikes.
- Review your experience modifier annually; a reduction of 0.1 can save thousands.
- Consider a self‑funded program only if your claim frequency is consistently below the state average.
Frequently Asked Questions
Is the % of sales the same as % of payroll?
No. % of payroll reflects the direct cost relative to wages, while % of sales translates that cost into a broader revenue context, useful for overall budgeting.
Do small businesses pay a higher % of sales?
Often, yes. Small firms have less payroll to spread the premium across, so the same dollar amount can represent a larger slice of sales.
Can I negotiate the rate?
Michigan rates are set by the state, but you can influence the final cost through safety improvements that lower your experience modifier.
