No single California workers’ comp settlement calculator can give you a reliable number, because the final figure is built from several moving parts: your permanent disability rating, your average weekly wage before the injury, the projected cost of your future medical care, any reduction for pre-existing conditions, and whether you take the money as a lump sum or as payments spread over time. Each piece has its own rules, and the way they combine is what produces the settlement value.
The Core Formula: Rating Times Weeks Times Weekly Rate
Permanent disability is the engine of the calculation. The rating is a percentage from 1% to 100% that expresses how much the injury has permanently reduced your ability to earn a living. A higher percentage means more weeks of benefits and a larger total payout.
The percentage comes out of a medical process. Once your condition is “permanent and stationary” — stable and unlikely to change substantially over the next year — a physician measures your impairment using the AMA Guides to the Evaluation of Permanent Impairment, 5th Edition, and assigns a whole person impairment score. For injuries on or after January 1, 2013, that score is multiplied by 1.4, then adjusted for your occupation (drawn from 45 occupational groups ranked by physical demand) and your age at the time of injury, using the lookup tables in the Permanent Disability Rating Schedule.
The resulting percentage translates into a set number of weeks of permanent disability payments:
- A 1% rating yields 3 weeks
- A 10% rating yields about 30 weeks
- A 50% rating yields roughly 271 to 286 weeks
- A 99% rating yields about 897 weeks
Those weeks are paid at a weekly rate tied to your pre-injury earnings. For injuries from 2013 forward, the permanent disability weekly rate runs from a minimum of $160 to a maximum of $290. In total indemnity, that works out to roughly $870 at the low end of a 1% rating up to about $260,000 for a 99% rating, before any lump-sum discounting or add-ons.
How Your Average Weekly Wage Sets the Dollar Rate
Your average weekly wage controls both the temporary disability you were paid while you recovered and the weekly rate used for permanent disability.
To find it, total earnings from the 12 months before the injury are divided by the days actually worked to produce a daily wage. That daily figure is multiplied by 260 for full-time workers (200 for seasonal workers) and then divided by 52. Overtime and non-discretionary bonuses are included; discretionary bonuses are not.
An example: a worker who earned $52,000 over 250 days worked has a daily wage of $208. Multiplied by 260 and divided by 52, that produces an average weekly wage of $1,040. Two-thirds of $1,040 is about $693 per week in temporary disability.
Temporary total disability rates adjust each January based on the State Average Weekly Wage, which rose to $1,789 for 2026. The 2026 minimum temporary total disability rate is $264.61 per week and the maximum is $1,764.11 per week. Temporary disability generally runs up to 104 weeks, with extensions possible for certain ongoing treatment.
Lump Sum or Ongoing Payments: The Two Settlement Structures
California workers’ comp cases resolve as one of two agreements, and the choice changes what the number represents.
Stipulated Findings and Award
In a stipulated award, you and the insurer agree on a rating, a weekly amount, and a duration. Benefits arrive in biweekly installments. Your right to future medical treatment for the injury stays open for life, with the insurer continuing to pay for care subject to utilization review. If your condition worsens, you can file a Petition to Reopen within five years of the injury date under Labor Code section 5410.
Compromise and Release
A Compromise and Release is a one-time buyout of the entire claim. You receive a lump sum covering permanent disability, any unpaid temporary disability, and the estimated cost of all future medical care for the injury. Once a judge approves it, the case closes permanently. The insurer has no further obligation even if you need another surgery later. You get cash up front and assume the risk of managing your own future medical costs.
Someone facing decades of pain management or likely future surgeries often prefers a stipulated award that keeps medical care open. Someone who wants a clean break and the freedom to treat outside the insurer’s medical provider network often prefers the lump sum. Either way, a workers’ compensation administrative law judge must review and approve the agreement.
When a stream of permanent disability or life pension payments is commuted into a lump sum, the total is discounted to present value using a 3% annual interest rate under Labor Code section 5101. The Division of Workers’ Compensation publishes present value tables that convert benefit weeks into a discounted figure; for life pension payments, the calculation also uses CDC life expectancy tables.
How Future Medical Costs Enter the Number
In a stipulated award, future medical care is not given a dollar value. It just stays open as the insurer’s continuing obligation. In a Compromise and Release, that cost becomes part of the lump sum, and the estimate matters.
The same medical report that sets your rating also outlines the treatment you are expected to need: surgeries, injections, physical therapy, durable medical equipment, pain management. Those services are priced using the California Official Medical Fee Schedule. The physician fee schedule conversion factor rose to $51.61 effective March 1, 2026, up from $48.79, which means the same future treatment plan costs more to buy out today than a year ago.
Once the future medical figure is folded into the lump sum, the insurer is released. If you exhaust the money before your treatment needs end, the balance is yours. This is why Compromise and Release numbers are heavily negotiated.
Medicare Set-Aside Allocations
If you are a Medicare beneficiary, or you reasonably expect to enroll in Medicare within 30 months, part of the lump sum may need to be placed in a Medicare Set-Aside account that must be spent on injury-related care before Medicare pays anything. The Centers for Medicare and Medicaid Services will review a proposed set-aside if you are a current Medicare beneficiary and the total settlement exceeds $25,000, or if you are a future enrollee and the settlement exceeds $250,000. Submission is technically voluntary, but without CMS review Medicare is not bound by the allocation and can later claim it was too low.
Apportionment Can Reduce the Award
Not all of the disability may be the employer’s responsibility. Under Labor Code sections 4663 and 4664, the evaluating physician must determine what share of your permanent disability was caused by the workplace injury versus other factors, including pre-existing conditions, age-related degeneration, congenital issues, or prior injuries.
If the physician finds that 30% of a back disability is due to pre-existing degenerative disc disease, the employer is liable only for the remaining 70%, and your compensation is based on that reduced percentage. Apportionment is one of the most heavily contested pieces of a workers’ comp case.
Add-Ons That Increase the Total Value
Several benefits sit on top of permanent and temporary disability.
Life pension. If your rating is 70% or higher but below 100%, you qualify for a life pension that begins after permanent disability payments end and continues for life. The weekly rate is calculated by subtracting 60 from the rating percentage, multiplying by .015, and multiplying that by your average weekly wage (capped at $515.38). An 80% rating at a $515.38 average weekly wage produces about $154.61 per week for life. For injuries on or after January 1, 2003, these payments receive an annual cost-of-living adjustment tied to the State Average Weekly Wage. Workers rated at 100% permanent total disability receive benefits for life at the temporary disability rate, adjusted annually.
Supplemental Job Displacement Benefit. If you have permanent partial disability and your employer does not offer regular, modified, or alternative work within 60 days, you receive a $6,000 non-transferable voucher for education or retraining at approved schools. To block the voucher, a qualifying job offer must last at least 12 months, pay at least 85% of pre-injury wages, and be within reasonable commuting distance.
Return-to-Work Supplement. If you receive the SJDB voucher, you can apply for a one-time $5,000 payment through the state’s Return-to-Work Supplement Program. Applications are due within one year of receiving the voucher.
Mileage reimbursement. Travel to medical appointments is reimbursed at $0.70 per mile.
15% return-to-work adjustment. For injuries between 2005 and 2012 at employers with 50 or more employees, permanent disability payments go up by 15% if the employer fails to offer qualifying work within 60 days, or down by 15% if the employer does. This adjustment was eliminated for injuries on or after January 1, 2013.
Rough Settlement Ranges by Body Part
Reported settlement data offers rough benchmarks for total case value by injured body part. These figures include permanent disability payments, disputed medical costs, and vocational rehabilitation:
- Head and brain injuries: $75,000 to $500,000 or more
- Lower back (lumbar spine): $30,000 to $200,000 or more
- Neck (cervical spine): $25,000 to $175,000 or more
- Shoulder: $20,000 to $120,000, with rotator cuff cases requiring surgery typically landing between $60,000 and $120,000
- Knee: $15,000 to $100,000, with meniscus or ACL repair cases typically settling between $40,000 and $80,000
- Hand and wrist: $10,000 to $75,000, with surgical carpal tunnel cases generally running $20,000 to $50,000
- Multiple body parts: $50,000 to $500,000 or more
Claims involving multiple injured body parts compound the disability rating and tend to settle for substantially more than single-injury claims. California generally uses the Combined Values Chart formula a + b(1−a) to merge separate ratings, so a 20% and a 15% combine to 32% rather than 35%, though in some circumstances the ratings can be added instead, producing a higher total.
What Comes Out of the Gross: Fees and Taxes
California workers’ compensation attorneys work on contingency. The fee is not a fixed statutory percentage; it has to be approved by a workers’ compensation judge based on a reasonableness standard. In practice fees typically run about 15% of the settlement, with 9% to 12% for straightforward cases and up to 20% for highly complex cases that go to trial. Costs for medical record copies, filing fees, and independent exams are usually advanced by the law firm and reimbursed from the settlement. Practitioners cite data suggesting represented workers typically recover roughly 30% more than those handling claims on their own.
Workers’ compensation benefits are generally tax-free under both federal and California law. Temporary disability, permanent disability, death benefits, and medical expense payments are excluded from gross income under Internal Revenue Code section 104(a) and aligned California Franchise Tax Board guidelines. There are exceptions. If you also receive Social Security Disability Insurance and the combined monthly total exceeds 80% of pre-injury earnings, the SSDI benefits may be reduced through an offset, and the offset portion can become taxable. Interest on delayed payments is taxable. Any portion of a settlement categorized as back pay is taxable, as are light-duty wages and any benefits awarded for employer retaliation under Labor Code section 132(a).
