Payroll by Class Code

Class 1 Annual Payroll
Estimated yearly payroll for employees in your main class code.
Class 1 Rate per $100
The rate per $100 of payroll for this class code, from your quote, policy or state rating bureau. The default is only a placeholder.
Class 2 Annual Payroll
Payroll for a second class code, such as clerical office employees. Leave at 0 if not needed.
Class 2 Rate per $100
The rate per $100 of payroll for the second class code.
Class 3 Annual Payroll
Payroll for a third class code, such as outside sales. Leave at 0 if not needed.
Class 3 Rate per $100
The rate per $100 of payroll for the third class code.

Rating Factors

Experience Modification Factor
Your experience mod from your rating worksheet. 1.00 is average; below 1.00 is a credit for better-than-average claims, above 1.00 a debit. New or small businesses often have no mod — use 1.00.
Schedule Credit (−) or Debit (+) (%)
A credit or debit the underwriter applies for factors such as safety programs. Enter a credit as a negative number. Limits vary by state.
Premium Discount (%)
The size-based premium discount on larger policies, from your quote.
State Assessments & Surcharges (%)
Taxes and assessments your state adds, as a percentage, from your quote.
Expense Constant & Fees
Flat policy fees from your quote, such as the expense constant.

Definitions

Workers' Compensation Premium terms, defined

The terms this calculator uses, in plain words. The same definitions appear inside the calculator for your visitors.

Workers' compensation insurance
Insurance that pays medical care and lost wages for employees injured or made ill on the job, and generally protects the employer from lawsuits over those injuries. Nearly every state requires employers with employees to carry it; rules on owners, small employers and exemptions vary by state.
Class code and rate
Each type of work is assigned a class code with a rate per $100 of payroll that reflects its injury risk — clerical work has a low rate, roofing a very high one. The rates come from your carrier and state rating bureau and change yearly.
Manual premium
Payroll divided by 100, times the class rate, added up across your class codes. $500,000 of payroll at $1.50 per $100 is a $7,500 manual premium before any adjustments.
Experience modification factor (EMR)
A multiplier based on your own claims history compared with similar businesses, usually over three years. A 0.85 mod cuts the premium by 15%; a 1.25 mod raises it by 25%. It is calculated by NCCI or your state bureau once a business is large enough to qualify.
Schedule rating
Credits or debits an underwriter may apply for things not reflected in your mod, such as safety programs, workplace condition or employee training. States limit how large they can be.
Standard premium and premium discount
Standard premium is the manual premium after the experience mod and schedule rating. Larger policies may then get a premium discount that reflects lower administrative cost per dollar of premium.
Payroll audit
Workers' comp is priced on estimated payroll, then audited after the policy year. If actual payroll was higher, you owe more premium; if lower, you get a refund. Keeping employees in the correct class codes avoids surprises.
