Step 1 — Your Business

Tell Us About Your Maryland Business

Enter your business details to calculate your workers' comp premium. We auto-populate Maryland-specific rates based on your industry.

Industry / Trade ?Select your primary business classification. Each industry has a unique NCCI class code that determines your base workers' comp rate. Higher-risk trades like roofing pay significantly more than office-based businesses.Source: NCCI Scopes Manual, class code system

Number of Employees ?Total W-2 employees covered under your workers' comp policy. Include all full-time and part-time employees. Independent contractors (1099) are not included but may require coverage in some states.Source: Maryland Workers' Compensation Commission

Annual Payroll ($) ?Total annual payroll for all employees on your WC policy. This is the primary driver of your premium calculation. Auto-calculated from employees x industry average wage, but you can override it.Source: BLS Occupational Employment & Wage Statistics, 2025

WC Rate per $100 Payroll ?The base workers' comp rate for your industry in Maryland, expressed per $100 of payroll. This rate is set by NCCI or your state rating bureau and varies significantly by industry and state. Pre-populated with Maryland data.Source: NCCI / Maryland Workers' Compensation Commission rate filings, 2025-2026

Step 2 — Experience & Claims

Your Claims History

Your Experience Modification Rate (EMR) is the single biggest lever on your premium. Enter your claims history to see how it impacts your costs and future trajectory.

Current EMR (Experience Mod) ?Your Experience Modification Rate from NCCI or your state rating bureau. 1.00 = industry average. Above 1.00 means higher premiums. Below 1.00 means lower premiums. Find this on your mod worksheet or ask your broker.Source: NCCI Experience Rating Plan Manual

Safety Program in Place? ?A formal written safety program with regular training can reduce claims frequency by 20-40% and may qualify you for premium credits from some carriers.Source: OSHA Safety Pays Program; Liberty Mutual Workplace Safety Index

Calculation Methodology ▼

How This Calculator Works

Annual Premium = (Annual Payroll / 100) × Base WC Rate × Experience Modification Rate (EMR)
PEO Premium = (Annual Payroll / 100) × PEO Pooled Rate × PEO Pooled EMR Factor
EMR Projection: Based on NCCI split-point formula. Claims history impacts future EMR over a 3-year rolling window.
PEO Discount: PEO rates use a discount factor of 0.52 applied to direct market rates, reflecting pooled buying power.
3-Year Trend: Direct carrier premiums trend at +3%/year (10-year average). PEO premiums trend at +2%/year due to scale.
Safety Credit: A 5% premium credit is applied when a formal safety program is in place.

Disclaimer: This calculator provides estimates for educational purposes. Actual premiums depend on your specific underwriting, claims history, and carrier selection. Data sources: NCCI, Maryland Workers' Compensation Commission, NAPEO, BLS. Calibrated to 2026 market conditions.
