Workers compensation is a state-mandated insurance system that provides wage replacement and medical coverage to employees who suffer work-related injuries or illnesses. The system is entirely employer-funded — workers pay no premiums and receive benefits regardless of fault. While the federal government sets no uniform benefit standard, all 50 states operate their own systems with meaningfully different weekly maximums, benefit rates, and duration rules. Understanding how your state calculates benefits — and how your injury type determines which formula applies — is the first step toward knowing what you are owed.
How Weekly Benefits Are Calculated
The vast majority of states set the weekly wage-replacement rate at two-thirds (66.67%) of the worker's Average Weekly Wage (AWW), but the dollar amount is bounded on both ends. Every state sets an annual maximum weekly benefit — typically pegged to a percentage of the state average weekly wage (SAWW), which is why the cap changes each year. California's 2024 maximum is $1,619.15; Iowa's is $2,085; Mississippi's is only $686. Some states also set a minimum weekly benefit to protect low-wage workers (New York at $150/week, California at $242/week). If your calculated two-thirds falls below the minimum, you receive the minimum. If it exceeds the maximum, you are capped. Several states deviate from the two-thirds rate: Iowa and Maine use 80%; Massachusetts and New Hampshire use 60%; New Jersey and Oklahoma use 70%; Ohio uses 72%; Rhode Island and Washington use a sliding-scale formula.
State Variation: Why Location Matters
Workers compensation is one of the most state-variable areas of employment law, and the differences are substantial enough that a worker earning the same wage can receive dramatically different benefits depending on where the injury occurs. Oregon's 2024 maximum of $1,817/week is more than 2.6 times Mississippi's $686/week cap. For PPD claims — which depend on state-scheduled benefit weeks — the variation is even wider. Wisconsin allows up to 1,000 scheduled weeks for a 100% whole-body impairment; California allows only 104. A 20% PPD rating produces 200 weeks of benefits in Wisconsin versus 20.8 weeks in California, even before applying the weekly rate. Workers in high-benefit states like Iowa, Oregon, Massachusetts, and Illinois receive substantially more generous compensation than those in lower-benefit states like Mississippi, Georgia, and Nevada.
Medical Coverage and Vocational Rehabilitation
Beyond wage replacement, workers compensation covers all approved medical treatment for the work injury — doctor visits, specialist care, surgery, physical therapy, prescription medications, and adaptive equipment — with no copays or deductibles for the worker. This medical coverage continues even after wage-replacement benefits end, as long as treatment is related to the work injury. Workers with permanent total or high-percentage permanent partial impairments are typically entitled to vocational rehabilitation services, including job retraining, education benefits, and job placement assistance, at no cost. The waiting period (3–7 days in most states) determines when wage benefits begin, but medical coverage starts immediately on the date of injury. If disability extends past the retroactive period (usually 14–21 days), wage benefits are paid retroactively to day one.
