How Are Lost Wages Calculated in a Washington Personal Injury Claim?
You get rear-ended on I-5 during your morning commute, spend six weeks recovering, and the paychecks you were counting on simply stop. With Washington’s average annual wage now around $95,160, or roughly $1,919 a week, six weeks out of work is more than $11,000 gone before you have opened a single medical bill.
So one of the first practical questions after a serious injury is: what are your lost wages actually worth, and how do you prove that number to an insurer who has every reason to shrink it?
Lost wages are one of the most concrete parts of a Washington personal injury claim, but concrete does not mean simple. The calculation changes depending on how you are paid, how long the injury keeps you out, and whether any part of the crash was your fault.
Here is how each piece works, with real numbers, and what to watch for before you rely on your own estimate.
What Lost Wages Actually Cover
Lost wages are the income you miss because of an injury someone else caused. In Washington they fall under economic damages, the measurable financial losses in a claim, and they cover far more than the base figure on your paycheck.
A complete lost-wage claim can include
- Your regular hourly or salaried pay
- Overtime you consistently work
- Bonuses and commissions,
- The value of benefits you lose while you are out
- Lost future earning capacity if the injury changes what you can earn going forward.
Two variables drive the math: how you earn (as a W-2 employee or as a self-employed person), and how long you are affected (a temporary absence or a permanent change in your ability to work). The sections below take each in turn.
If You Are a W-2 Employee
For employees, past lost wages are usually the most straightforward part of a claim, because your income is already documented by your employer.
Immediate lost earnings are the wages you would have earned from the date of injury until your settlement or trial. For hourly workers, multiply the hours you missed by your hourly wage. For salaried workers, divide your annual salary by your workdays in a year to get a daily rate, then multiply by the days you missed.
Example: At $20/hour, missing 100 hours of work equals $20 x 100 = $2,000.
Overtime and bonuses belong in the claim too, as long as you can show they were a regular and expected part of your income rather than a one-off. Pay stubs, employer records, and prior tax returns that show a consistent pattern are what make them recoverable.
Example: Averaging 5 overtime hours a week at a $30/hour overtime rate, across 4 missed weeks, equals 5 x $30 x 4 = $600.
Lost benefits count as well. Employer contributions to a retirement plan, health insurance, or stock options that you forfeit while you are off work have real value.
Example: A $300 monthly health insurance contribution across 2 missed months equals $300 x 2 = $600.
To document an employee claim, you will generally use pay stubs, your IRS Form W-2, and a letter from your employer confirming the time you missed and the pay you lost. If your earnings history is ever disputed, the Washington Employment Security Department maintains the wage records that employers report each quarter, which can independently confirm what you were making.
If You Are Self-Employed, a Contractor, or a Gig Worker
Self-employed people are just as entitled to lost income, but the proof works differently. There is no employer to confirm your hours, so the claim is built entirely on your own financial records showing what you would reasonably have earned.
Lost income here is based on the business you could not do: missed contracts, canceled jobs, and interrupted income streams during your recovery.
Example: Averaging $5,000 a month in earnings across 3 missed months equals $5,000 x 3 = $15,000.
The documentation that carries a self-employed claim includes your prior tax returns and IRS Schedule C, which reports profit or loss from a business, along with profit-and-loss statements, client invoices, signed contracts, 1099s, and bank deposit records. Because self-employed income tends to swing month to month, a longer earnings history usually produces a stronger and more defensible number than a single recent month would. This is also the category insurers challenge hardest, so the quality of your records often decides how much of the claim survives.
Future Lost Earnings and Loss of Earning Capacity
If an injury causes a long-term or permanent disability that changes what you can earn, you can claim future lost earnings on top of what you have already lost. In serious cases this is often the largest single component, and it is also the most technical.
For a permanent disability, the calculation is the difference between your pre-injury and post-injury earning capacity, projected across your expected remaining working years.
For a temporary disability, you estimate how long you will be unable to work and multiply by your regular earnings.
A projection like this rarely stands on an unverified claim . An economist, and often a vocational expert, assess how the injury limits your ability to work and what comparable work you could still do. They rely on occupational wage and outlook data such as the U.S. Bureau of Labor Statistics Occupational Outlook Handbook and Washington’s own occupational employment and wage statistics to ground the numbers in real market data.
Example: Say you earned $50,000 a year before the injury and can now earn only $30,000.
- Annual gap: $50,000 – $30,000 = $20,000
- Remaining working years: 20
- Gross lifetime loss: $20,000 x 20 = $400,000
That $400,000 is the gross figure, not the payout. Washington requires future losses to be reduced to present value, which means the award reflects what that future income is worth as a lump sum today, not the full total added up year by year.
The Washington Rules That Move Your Number
Two Washington rules can change your final figure.
- Comparative fault reduces what you recover
Under RCW 4.22.005, your recovery drops by your share of fault, but you can still recover even if you were mostly at fault. If your damages are $100,000 and you are 20% at fault, you get $80,000. That cut applies to your lost wages too, which is why fault is often the most fought-over part of a claim. Our guide to the average car accident settlement in Washington covers how fault moves a case.
- You have a duty to mitigate
Washington expects you to take reasonable steps to limit your losses. If your doctor clears you for lighter work and suitable work is available, the income you could have earned may reduce your claim. This is about reasonable effort, not taking work your injury actually prevents.
Why the Formula Is Only a Starting Point
The math above gives you a good estimate of what you lost. But an estimate is not the same as money in your pocket. The insurance company still has to agree to pay it, and often they will not.
Instead, adjusters look for reasons to pay less. They may say your overtime was not regular enough to count. They may say you cannot really prove your self-employed income. They may say your future-earnings number is too high. Every one of these arguments has one purpose: to pay you less than your loss is actually worth.
Beating those arguments comes down to how well your claim is documented.Brumley Law Firm has recovered results that show what a well-documented car accident claim can be worth, including a $900,000 recovery for an injured client.

Common Questions About Lost Wages in Washington
How do I calculate my lost wages after a car accident?
Start with your pay rate multiplied by the work time you missed, from the date of the injury until your recovery or settlement.
Add regular overtime, bonuses, and the value of any benefits you lost.
If you are self-employed, base the figure on documented business income you could not earn. If a permanent injury reduces your ability to work, add projected future lost earnings on top.
Can I include overtime and bonuses in a lost wages claim?
Yes, if you can show they were a regular and expected part of your income. Pay stubs, employer records, and prior tax returns that document a consistent pattern of overtime or bonuses are what support including them.
How do self-employed people prove lost income?
With records of their normal earnings in form of prior tax returns and Schedule C, profit-and-loss statements, client invoices, signed contracts, 1099s, and bank deposit records. The goal is to show what you would reasonably have earned during the time you could not work. A longer earnings history usually makes for a stronger claim.
What documents do I need to prove lost wages?
Employees typically need pay stubs, a W-2, and an employer letter confirming missed time and pay. Self-employed claimants need tax returns, profit-and-loss statements, invoices, and bank records. In both cases, medical records connecting the injury to your inability to work are essential, and an economist or vocational expert may be needed for future losses.
Does a settlement cover future lost income from a permanent injury?
It can. If a permanent or long-term injury reduces your earning capacity, you can claim the difference between what you could have earned and what you can earn now, projected across your expected working years and reduced to present value. These projections usually require an economist or vocational expert.
Will being partly at fault reduce my lost wages?
Yes. Under Washington’s pure comparative fault rule, your total recovery, lost wages included, is reduced by your percentage of fault. Being partly at fault lowers what you collect, but it does not bar you from recovering.
Don’t Estimate Your Losses Alone
A few weeks off work is real money in Washington, where the average worker earned about $1,919 a week, and a permanent injury can put six or seven figures of future earning capacity on the table. Those are not numbers to hand an insurance adjuster without support behind them.
At Brumley Law Firm, we document every category of loss, from the first missed paycheck to long-term earning capacity, and we build the record needed to defend those figures if a fair offer does not come.
