A workers comp premium calculator built on payroll, class codes and the mod

The employer enters payroll and a rate per $100 for up to three class codes, then the experience mod, schedule credit or debit, premium discount, state assessments and fees. Your agency receives the full rating worksheet and an effective cost per $100 of payroll.

This workers comp premium calculator follows the standard rating order: payroll divided by 100 times each class rate gives manual premium, then the experience modification factor, schedule rating, premium discount, state assessments and expense constant are applied. Commercial agencies embed it so employers arrive with payroll, class mix and their mod already on the page.

What the inputs tell you before the call

InputsWhat it tells your producer
Class 1 Annual PayrollPayroll in the main class code sizes the account before you open an application.
Class 1 Rate per $100A rate taken from a current quote or policy hints at the governing class and whether the account sits in a high-hazard class.
Class 2 Annual PayrollA second class such as clerical shows whether payroll is being split across codes, a common source of audit surprises.
Experience Modification FactorA mod above 1.00 points to loss history and a safety or claims-management conversation; below 1.00 is a credit to protect.
Schedule Credit (−) or Debit (+) (%)Shows whether the current carrier credits their safety program, and room to discuss it with underwriters.
State Assessments & Surcharges (%)Taken from a quote, it suggests they have a current policy or renewal document in hand, so an X-date is near.

Your first call

How do you open a workers' comp lead that arrives with a mod?

Employers who run this calculator already know the moving parts of their premium. The first call is about verifying classifications and payroll, not promising a lower number.

  1. 01You entered [payroll] in your main class at [rate] per $100 and a [mod] experience mod. Could you send your current declarations and rating worksheet so I can check the classifications against your operations?
  2. 02Your mod effect came out at about [mod effect]. Do you know which claims are driving it? Sometimes reviewing reserves and loss runs with the carrier is the first step.
  3. 03Your premium is estimated on payroll and trued up at audit. Are you expecting payroll changes this year, so we can estimate it accurately and avoid an audit bill?

Where to place it on your site

  • Workers' compensation page

    Employers searching for comp costs get a rating walk-through instead of a contact form.

  • Industry pages for contractors or restaurants

    High-payroll, high-rate classes are where the mod and class mix matter most.

  • Renewal season emails to commercial clients

    Clients can model payroll changes before the renewal application goes out.

  • New business owner resources

    First employees trigger comp requirements in most states, and owners want a cost range.

How does the calculator build a workers' comp premium?

It applies the factors in the usual rating order. Manual premium is payroll divided by 100 times the class rate, summed across up to three class codes. That is multiplied by the experience mod and adjusted for schedule rating to reach standard premium, then reduced by the premium discount and increased by state assessments and flat fees.

The results show each stage separately: manual premium, the experience mod's effect in dollars, standard premium, the estimated annual premium, total payroll and the effective cost per $100 of payroll. That breakdown is what makes the lead useful to a commercial producer.

The calculator supplies no rates. Each class rate comes from the employer's own quote, policy or state rating bureau, and the tooltips say the defaults are placeholders.

  • Manual premium = Σ (payroll ÷ 100 × class rate)
  • Standard premium = manual premium × experience mod × (1 + schedule %)
  • Estimated premium = standard × (1 − premium discount) × (1 + assessments) + expense constant

What rating rules does the estimate leave out?

It leaves out anything that depends on a specific state or carrier filing: payroll caps for owners and officers, minimum premiums, state-specific surcharges and credits, and the final payroll audit. Rates themselves are set through NCCI or an independent state rating bureau and carrier filings, and they change every year.

The four monopolistic states, North Dakota, Ohio, Washington and Wyoming, run state funds with their own rules, and the disclaimer says so. Agencies in those states can still use the calculator to explain the concept of rate per $100 and the experience mod, but should position the result carefully.

The definitions explain the payroll audit in plain language: premium is charged on estimated payroll and adjusted after the policy year, so higher actual payroll means more premium and lower payroll means a refund.

Which agencies should embed a workers' comp calculator?

Commercial-lines agencies and small-business specialists, especially those focused on contractors, restaurants, healthcare, trucking or other classes where workers' comp is the largest premium on the account. It also suits agencies running PEO alternatives or pay-as-you-go programs, because employers arrive understanding their payroll and class structure.

A lead with three class codes, a mod and schedule rating is a qualified commercial prospect: they have a policy, they know their numbers, and they are thinking about cost.

Because the lead includes payroll by class, your team can decide before the call whether the account fits your markets and appetite.

Terms the widget explains

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.

Compliance notes for this line

  • The calculator estimates premium from rates and factors the employer enters. It is not a quote, and only a licensed producer with the carrier can bind workers' compensation coverage.
  • Workers' comp rules, class codes, owner and officer inclusion and exemptions vary by state, and four states use monopolistic state funds. Check the rules where the employer operates.
  • Do not suggest moving employees to lower-rated class codes to save money; classification follows the work performed and is checked at audit.
  • Obtain TCPA-compliant consent before calling or texting business leads where the law requires it. This is not legal advice.

FAQ

Questions agencies ask

Answers first, details after.

Does the calculator include workers' comp rates for each state?

No. It supplies no rates. The employer enters the rate per $100 of payroll for each class code from their quote, policy or state rating bureau. Rates are set through NCCI or independent state bureaus and carrier filings, and they change every year.

How many class codes can an employer enter?

Up to three, each with its own payroll and rate per $100. The tooltips suggest typical uses such as a main operations class, clerical office employees and outside sales. Unused classes stay at zero.

What does the experience mod effect show?

It shows the dollar impact of the experience modification factor on manual premium. A 0.85 mod reduces premium by 15%, and a 1.25 mod raises it by 25%. New or small businesses without a mod use 1.00.

What is effective cost per $100 of payroll?

It is the estimated annual premium divided by total payroll, times 100. It lets an employer compare all-in cost across years or quotes after the mod, schedule rating, discounts, assessments and fees are applied.

Does it handle monopolistic states?

The disclaimer notes that North Dakota, Ohio, Washington and Wyoming use state funds with their own rules. The calculator's structure may not match how those funds rate a policy, so producers in those states should treat the output as illustrative.

Does it account for the payroll audit?

It explains it. The definitions describe how premium is charged on estimated payroll and adjusted after the policy year. The calculator itself uses the payroll entered, which is why estimating payroll accurately matters.

Can we route workers' comp leads to a commercial team?

Yes. Each calculator can have its own webhook, so this calculator can post to a commercial-lines pipeline while personal-lines calculators post elsewhere. Without a per-calculator webhook, the agency-wide one is used.

What does a workers' comp lead contain?

Contact details, consent, payroll and rate for each class, the mod, schedule rating, discount, assessments and fees, every result row, and attribution such as UTM tags, click IDs and landing page.

Which plan includes the workers' comp calculator?

Every plan, including the free Producer plan with up to 5 calculators. Agency at $150 a month raises that to 50 and adds webhooks; monthly and yearly billing start with a 14-day free trial.
