Workers' Comp Disability Check Too Low? Audit the Wage Calculation

A temporary disability check can arrive on time and still be wrong.

The claims administrator may have used one pay stub instead of a fair wage history. Overtime, commissions, piece-rate earnings, shift differentials, or a second job may be missing. The calculation may use the wrong injury date or work-status period. Sometimes the wage math is fine, but the check covers fewer days because the administrator relied on a medical note, return-to-work offer, or payment period the worker has not seen.

Do not start with “two-thirds of my paycheck.” Start with the actual inputs.

This article provides general information, not legal advice or a personal benefit calculation. Temporary disability payments depend on the date of injury, average weekly earnings, statutory limits, medical work status, payment periods, employment facts, and the complete claim record.

The 2027 Minimum-Wage Increase Does Not Automatically Recalculate Every TD Check

On August 13, 2026, California's Department of Industrial Relations announced that the statewide minimum wage will increase to $17.40 per hour on January 1, 2027. Some cities and counties may require a higher local rate.

That prospective wage-law change does not, by itself, establish a new temporary-disability rate for every worker with an existing claim. Workers' compensation disability calculations generally depend on average weekly earnings, the date of injury, statutory limits, medical status, and the claim record. A later minimum-wage increase is not a substitute for applying those rules to the actual case.

The announcement still gives workers a good reason to inspect their pay records. If the wage statement omitted earnings, used the wrong hourly rate, ignored another job, or relied on an unfairly narrow period, the payment may require review for reasons separate from the 2027 increase. Keep wage-law questions and workers' compensation calculations in separate columns.

Temporary Disability Is a Wage-Loss Benefit

California's Division of Workers' Compensation describes temporary disability benefits as payments made when a work injury prevents a worker from doing the usual job while recovering and causes wage loss.

Temporary total disability and temporary partial disability are different:

• Temporary total disability: the worker cannot work during the covered period.
• Temporary partial disability: the worker can perform some work but earns less because of the injury and restrictions.

A worker who received a smaller check may therefore have more than one possible problem. The administrator may dispute the wage base, the medical work status, the dates covered, the availability or pay of modified work, or some combination of them.

Get the benefit notice and check stub before guessing which fight you have.

The General Two-Thirds Rule Is Only the Starting Point

Labor Code section 4653 states that temporary total disability is two-thirds of average weekly earnings during the period of disability.

That sentence does not mean every worker can take the last net deposit, multiply it by two-thirds, and prove the carrier made an error.

The calculation can turn on:

• gross earnings rather than take-home pay;
• the method used to determine average weekly earnings;
• the worker's schedule and rate at the time of injury;
• earnings from more than one employer;
• irregular, commission, or piece-rate earnings;
• whether the worker regularly worked fewer than 30 hours;
• the statutory minimum and maximum tied to the injury date;
• whether the payment is temporary total or temporary partial disability; and
• which days the medical and work records show as covered disability days.

The correct question is: What average weekly earnings figure did the administrator use, how was it calculated, and which payment dates did it apply to?

Average Weekly Earnings Are Not Always the Last Week's Pay

Labor Code section 4453 contains several methods for determining average weekly earnings.

Regular full-time work

For employment of at least 30 hours a week and at least five working days a week, the statute refers to the number of working days per week multiplied by the daily earnings at the time of injury.

That makes the rate and schedule records important. Save the pay stub closest to the injury, but do not stop there. Keep the timecard, posted schedule, rate-change notice, union wage information if applicable, and payroll history needed to show the real arrangement.

Two or more jobs

Section 4453 addresses workers employed by two or more employers at or around the time of injury. The earnings may be aggregated under the statute's method, with a limitation on the rate used for the other employment.

If the claims administrator knows only about the job where the injury occurred, the wage base may be incomplete. Preserve pay stubs, schedules, W-2s, direct deposits, and employer contact information for each job. Do not assume the second employer's income was automatically included.

Irregular, commission, or piece-rate earnings

For earnings paid at an irregular rate, by piecework, by commission, or over another period, section 4453 allows actual weekly earnings to be averaged over a period that reasonably establishes the weekly rate, up to one year.

One unusually slow or unusually busy week can distort the picture. Save enough payroll history to show the pattern, including commissions earned but paid later, piece counts, incentive pay, and seasonal changes.

Part-time work or an unfair standard method

When the worker was employed fewer than 30 hours per week, or when the standard methods cannot reasonably and fairly be applied, section 4453 refers to the sum that reasonably represents the worker's average weekly earning capacity at the time of injury, with consideration of actual earnings from all sources and employments.

That is not permission to invent future income. It is a reason to preserve the complete work history instead of letting a thin payroll snapshot become the whole case.

Statutory Minimums and Maximums Can Change the Result

Section 4453 sets limits on the average weekly earnings used for disability calculations and ties later adjustments to the statewide average weekly wage. The injury date matters because disability indemnity generally uses the limits in effect for that injury.

This creates two common misunderstandings:

1. A worker may calculate two-thirds of a high weekly wage and overlook the applicable maximum.
2. A low-wage worker may assume a tiny check is necessarily correct without checking the applicable minimum and the statute's qualifications.

Do not use a current online rate table for an old injury without checking which year and benefit type the table covers. Temporary disability and permanent disability also use different rules and schedules. A permanent-disability advance is not proof of the temporary-disability rate.

Audit the Gross Wage Record, Not Just the Bank Deposit

Bring together the wage records from before the injury:

• pay stubs;
• timecards and payroll summaries;
• work schedules;
• hourly-rate and salary notices;
• regular overtime history;
• shift or hazard differentials;
• commission statements;
• piece-rate or production records;
• bonus and incentive records;
• tip records where relevant;
• W-2s and tax records;
• direct-deposit statements;
• union wage schedules or collective-bargaining provisions where applicable;
• records from concurrent jobs; and
• messages about rate changes, missed shifts, or reduced hours.

Do not assume every item must be included in the legal wage base. Preserve it so the actual rule can be applied to the actual pay structure.

Gross earnings and net deposit are not the same thing. Taxes, insurance, retirement deductions, garnishments, and other withholdings can make the bank deposit a poor starting point for reconstructing earnings.

Compare the Notice, Check Stub, and Covered Dates

For each benefit period, record:

• Benefit type: temporary total, temporary partial, permanent disability, or another payment.
• Period covered: first and last date stated on the notice or stub.
• Days paid: number of disability days represented.
• Wage base: average weekly earnings or rate used, if disclosed.
• Weekly benefit rate: amount the administrator says applies.
• Gross payment: amount before any stated deductions or credits.
• Check or issue date: date printed on the check or notice.
• Deposit date: date funds became available.
• Explanation: start, change, suspension, credit, overpayment, or other stated reason.

A smaller deposit may reflect a partial payment period rather than a lower weekly rate. It may also reflect a credit, withholding, return-to-work date, or transition to a different benefit. The notice should explain the basis. If it does not, ask for the calculation in writing.

WCLG's separate guide explains how to build the broader record when workers' comp checks are late, missing, or stopped.

Medical Work Status Can Change the Check

The wage calculation is only one half of temporary disability. The medical and work records determine whether the worker was off work, released with restrictions, or returned to regular work during the payment period.

Compare the check dates against:

• every work-status slip;
• primary treating physician reports;
• changes in restrictions;
• appointment and report dates;
• written modified-work offers;
• actual hours and wages earned after returning; and
• messages showing whether the employer could accommodate the restrictions.

If the doctor released the worker to modified duty and the employer offered work, the payment issue may turn on the terms, timing, pay, and medical fit of that offer. See WCLG's guide on modified duty that does not match work restrictions.

Do not ignore an incorrect work-status note. Ask the treating office about factual errors promptly and preserve the original and any corrected report.

Ask Precise Questions in Writing

“Why is my check low?” invites a vague answer. A useful written request asks for specific inputs:

Please provide the average weekly earnings figure, weekly temporary disability rate, wage records used, calculation method, statutory minimum or maximum applied, benefit type, and dates covered by the payment issued on [date]. Please also identify the medical work-status report and any modified-work earnings or credits used.

Attach only the records needed to identify the problem. Keep the message, attachments, delivery confirmation, and response. Do not send original documents or unrelated private records.

If a phone call produces an explanation, send a short written follow-up confirming what was said.

Low-Payment File Checklist

Bring these records to a payment review:

• date of injury and claim number;
• DWC-1 and claim-status notices;
• every benefit notice and check stub;
• bank or direct-deposit record;
• pay stubs and payroll history before injury;
• records from concurrent jobs;
• commission, piece-rate, overtime, differential, and incentive records;
• work schedules and timecards;
• every work-status report and restriction;
• modified-work offers and post-injury wage records;
• the administrator's written calculation;
• a table of payment periods, issue dates, deposits, and amounts; and
• messages with the employer, adjuster, payroll, and medical office.

Keep temporary and permanent disability notices in separate folders. Similar-looking checks can use different legal rules.
