How Workers' Comp Settlements Are Calculated
Short answer: a workers' comp settlement is the wage-loss benefits you are still owed, plus the permanent impairment award your state allows, plus the future medical care you agree to give up. The insurer then offers less than that total because it pays now instead of over time.
Settlement value = wage-loss benefits + permanent award + future medical
Wage-loss benefits are usually about two-thirds of your average weekly wage, limited by your state's weekly maximum and minimum. Your average weekly wage is normally your gross pay for the 13 weeks before the injury divided by 13, though some states use 52 weeks or after-tax pay.
The permanent award comes after you reach maximum medical improvement (MMI) and a doctor rates any lasting impairment. Each state turns that rating into money differently: some use a schedule of weeks per body part, some use a whole-person formula, and some (like Washington) pay fixed dollar amounts. That is why this calculator sends you to your own state's impairment calculator when we have verified its rules.
Future medical only belongs in a settlement if you give up the right to future treatment. Past medical bills are normally paid directly by the insurer, and no official workers' comp formula multiplies medical bills. That "1.5 to 3 times medical" rule comes from personal-injury cases that pay pain and suffering, which workers' comp generally does not. See our pain and suffering guide.
The Workers' Comp Settlement Formula, Step by Step
Short answer: weekly benefit = average weekly wage × your state's percentage, capped at the state maximum. Permanent award = rating × the weeks your state assigns × that weekly benefit. Add unpaid wage benefits and any future medical you give up.
- Work out your average weekly wage (AWW) from gross pay, including regular overtime and second-job wages where your state counts them.
- Multiply by your state's percentage (two-thirds in most states) and apply the weekly maximum and minimum for your injury date.
- After maximum medical improvement, multiply your impairment rating by your state's weeks for that body part or for the whole person.
- Multiply those weeks by the weekly rate your state uses for permanent awards (some states cap it lower than the wage-loss rate).
- Add any temporary benefits still owed and, only if you give up future treatment, an amount for future medical care.
Scheduled example: Louisiana arm
10% arm rating × 200 weeks = 20 weeks. 20 weeks × $800 a week = $16,000.
Louisiana payout calculatorWhole-person example: Tennessee
$1,200 AWW × 66⅔% = $800 a week. 10% rating × 450 weeks = 45 weeks × $800 = $36,000.
Tennessee payout calculatorSome states don't follow this pattern at all: Minnesota pays a fixed dollar schedule, Michigan pays wage loss instead of a rating award, and Pennsylvania uses a rating to change disability status. Use your state's own calculator for the exact rule.
Settlement Value by Injury Type
Short answer: injuries that need surgery, leave permanent restrictions or require lifelong care settle for more because they raise all three parts of the formula. The table shows modeled reference scenarios, not observed settlement averages or any state's legal schedule.

Reference scenario: $1,200 average weekly wage, $800 weekly benefit, 312 reference weeks (500 for whole-person), the modeled rating range and a modeled medical load. Wage-loss weeks are not included. For a state-specific version, open your state settlement chart.
What Changes a Settlement the Most
- Your state. Weekly maximums range from under $700 to over $2,000, and permanent award rules differ completely. Compare weekly benefit rates by state.
- Your wage. Higher wages raise the weekly benefit until the state maximum is reached.
- Your impairment rating. A few rating points can change the permanent award by thousands of dollars. Use the impairment rating calculator.
- Whether you keep future medical. Closing future medical raises the settlement but makes you responsible for later treatment.
- Disputes. If the insurer disputes the injury, wages or rating, offers usually reflect that risk.
When to Settle and Red Flags
Short answer: the safest time to consider settling is after you reach MMI, have a documented impairment rating and know what future treatment you need.
- The offer comes before MMI or before a rating.
- It includes nothing for future medical even though treatment is ongoing.
- You are pressured to sign quickly.
- The wage used is lower than your pay stubs show.
Consulting a workers' comp lawyer before you sign often helps workers understand what an offer leaves out, though no result is guaranteed. Read when workers' comp offers a settlement.

Settlement Calculator FAQ
How much is a workers' comp settlement worth?+
A workers' comp settlement is usually worth the unpaid wage-loss benefits, the permanent impairment award your state allows, and the expected cost of future medical care you give up, minus a discount for paying early. For example, $16,000 of remaining wage benefits, a $24,000 permanent award and $15,000 of future medical add up to $55,000 of face value before negotiation, fees and liens. There is no national average that fits every claim because each state calculates permanent awards differently.
How is a workers' comp settlement calculated?+
A workers' comp settlement is calculated by adding three components: the present value of unpaid or future TTD benefits, the permanent impairment (PPD) award based on your impairment rating and your state's award rules, and an estimate of future medical costs. The carrier then discounts the total to settle early. For example, a claim with $30,000 in TTD value, a $40,000 PPD award, and $15,000 in anticipated future medical has a face value of $85,000. These are hypothetical figures, not observed outcomes or a prediction of what a lawyer will recover.
Does the type of injury change a workers' comp settlement?+
Yes, but indirectly. The injury itself is not priced; what changes is how long you are off work, the permanent impairment rating at maximum medical improvement, and how much future treatment you need. A sprain that heals with therapy usually has a low or zero rating, while a fusion or joint replacement usually carries a higher rating, longer time off and more future medical, which raises every component.
Do insurers multiply medical bills to set a settlement?+
No official workers' comp formula multiplies medical bills by 1.5 to 3. That rule of thumb comes from personal-injury cases that pay pain and suffering, which workers' comp generally does not. In workers' comp, past medical bills are normally paid directly by the insurer; a settlement includes future medical only when you give up the right to future treatment.
How much do workers' comp attorneys charge?+
Attorney fees vary by state, claim type, and the written fee agreement. Some states use percentage caps, sliding schedules, or court or agency approval. Fees and case expenses may be treated differently. Ask the lawyer to explain the applicable rules and your estimated net recovery before signing.
Is it better to settle or keep receiving weekly benefits?+
It depends on your medical situation and financial needs. Weekly benefits provide ongoing support and keep your medical care funded by workers' comp. A lump-sum settlement gives you a larger immediate payment but closes the claim, including future medical coverage. Settling makes sense when you have reached MMI, your medical needs are predictable, and the settlement offer accurately reflects your long-term exposure. It does not make sense if you have upcoming surgery, unresolved dispute over AWW, or ongoing treatment needs that are not accounted for in the offer.
Can I reopen a workers' comp claim after settling?+
Generally no. A workers' comp settlement is a final resolution of the claim. In most states, signing a settlement agreement prevents you from seeking additional benefits for the same injury - including future medical care. A few states allow petitions to reopen if your condition significantly worsens within a certain timeframe, but this is the exception. Because settlement is final, it is critical to settle only after you fully understand your injury, impairment rating, and medical prognosis.
How long does a workers' comp settlement take?+
Timing varies widely. Negotiation, settlement paperwork, any required board or court approval, and any Medicare Set-Aside review all add time. Simple, uncontested claims may close within a few months, while claims with surgery, disputes or a Medicare Set-Aside can take a year or longer.
What is a Medicare Set-Aside (MSA) in workers' comp?+
A Medicare Set-Aside is a portion of a workers' comp settlement set aside specifically to pay for future medical costs that Medicare would otherwise cover. CMS (Centers for Medicare and Medicaid Services) reviews MSAs for settlements involving Medicare beneficiaries, or workers with a reasonable expectation of Medicare enrollment within 30 months, when review thresholds are met. The MSA must be spent on the injury-related medical care before Medicare will cover any related costs.
Will my workers' comp settlement affect my Social Security benefits?+
Workers' comp settlements can reduce your Social Security Disability Insurance (SSDI) benefit through the 'workers' comp offset.' If your combined workers' comp and SSDI exceeds 80% of your average current earnings before disability, SSDI is reduced. The offset applies until you reach full Social Security retirement age. How the settlement is worded can affect the offset, so tell everyone involved if you receive or have applied for SSDI.
