Delaware Workers' Compensation Premium Calculator

Estimate annual workers' comp insurance cost for Delaware employees.

Free Delaware workers' compensation premium calculator for 2025. Estimates employer comp cost using the class-code base rate per $100 of payroll, your experience modifier, and schedule credits, following Delaware Compensation Rating Bureau (DCRB) classification rules.

How is a Delaware workers' comp premium calculated?

The base formula is (annual payroll divided by 100) times the class-code base rate, then multiplied by your experience modification factor (EMR), then adjusted for any schedule credits or debits. So a $250,000 payroll at a $1.40 per $100 rate gives a $3,500 manual premium before the EMR and credits. Delaware follows Delaware Compensation Rating Bureau (DCRB) classifications and loss costs.

This calculator estimates a Delaware employer’s workers’ compensation premium using the standard insurance formula. Premium is charged per $100 of payroll at a rate set by your job class code, then adjusted by your experience modifier (EMR) and any schedule credits or debits. Delaware has no monopolistic state fund — coverage comes from private carriers under Delaware Compensation Rating Bureau (DCRB) classifications.

How it works

The premium builds up in three steps:

Manual premium = (Annual payroll ÷ 100) × class base rate Modified premium = Manual premium × EMR Net premium = Modified premium − schedule credit (or + debit)

The class base rate reflects the injury risk of the work — clerical work is cheap, roofing is expensive. The EMR personalizes the rate to your own loss history, and schedule credits or debits reflect carrier judgment about your safety program.

Delaware workers’ comp rules explained

  • Premium is per $100 of payroll, by DCRB class code.
  • The EMR starts at 1.00 for new/average employers; lower is better.
  • Delaware has no state fund — coverage is bought from private carriers.
  • Carriers apply a loss cost multiplier to DCRB loss costs to set the final rate.

Worked example

A restaurant with $250,000 payroll, class rate $1.40 per $100, EMR 1.00, no credits:

  • Manual premium = ($250,000 ÷ 100) × $1.40 = $3,500
  • Modified premium = $3,500 × 1.00 = $3,500
  • Net annual premium ≈ $3,500 (about $292/month)

Note: This is an estimate, not a quote. Actual premium depends on exact class codes, current DCRB loss costs, the carrier’s loss cost multiplier, audited payroll, the expense constant, and state assessments. Confirm with a licensed Delaware insurance agent.
