    This calculator provides a rough estimate only and does not account for overtime, benefits, raises, or present-value discounting. Actual lost wages in a California personal injury case may be significantly higher. Consult an attorney for an accurate assessment.

    Why This Matters

    Missing work after an accident is stressful enough. Then you start doing the math on what you’re actually losing, and it gets worse.

    Most people underestimate the real number because “lost wages” covers more than missing paychecks. It’s a bundle of economic losses – past earnings, future earnings, and something called lost earning capacity.

    We built the calculator below to help you get a clearer picture. Here’s how it works and what goes into the math.

    The Three Parts of a Lost Wages Claim

    Most people only think about the first one:

    • Past lost earnings are what you would have earned between your injury date and today (or the date of settlement). This is the straightforward part. Your hourly rate or salary, multiplied by the time you missed.
    • Future lost earnings cover income you’re reasonably certain to lose going forward. If your doctor says you can’t return to full duty for another six months, that’s future lost earnings.
    • Lost earning capacity is the one that people tend to overlook. Even if you return to work, your injury may limit what you’re able to earn long-term. A construction worker who can no longer do heavy lifting might have to take a lower-paying desk job. That gap between what you could have earned and what you can earn now? That’s lost earning capacity, and California law says you can recover it even without a strong work history.

    What Actually Goes Into the Calculation

    Your base pay is the starting point, but it’s not the whole picture. The calculator accounts for:

    • The overtime you would have worked. If you regularly put in extra hours, those lost overtime wages count. California uses a 1.5x multiplier for most overtime.
    • Bonuses and commissions you missed. That quarterly bonus you were on track to receive? It’s part of your loss.
    • Benefits your employer was paying for. Health insurance, retirement contributions, paid time off. Benefits typically add 30% or more on top of your base wages. Most people leave this money on the table.
    • Mitigation offsets. If you earned any income during recovery – light-duty work, freelance, anything like that – it gets subtracted from your lost wages. California law requires you to make reasonable efforts to work if you’re able to, but nobody expects you to push through work that would worsen your injury.

    Why Future Losses Get Complicated

    Projecting future earnings means factoring in wage growth (what raises you likely would have received) and then discounting that number back to its present value. A dollar twenty years from now is worth less than a dollar today, and California requires future economic damages to be reduced to “present cash value.”

    The calculator handles this math for you. You plug in your current earnings, expected growth rate, and how many working years you have left. It runs the present value formula, so you don’t have to.

    One thing worth knowing: California is one of the states that prohibits reducing your lost earnings estimate based on race, ethnicity, or gender. Your calculation should reflect your individual earning potential, period.

    Self-Employed? It Still Works

    If you’re self-employed, the inputs are different, but the logic is the same. Instead of pay stubs and W-2s, you’re working from tax returns, 1099s, and Schedule C filings. The calculator lets you toggle between hourly, salaried, and self-employed modes so the math fits your situation.

    The Calculator Is a Starting Point. Not a Substitute for Legal Advice.

    A calculator gives you a useful ballpark, but some things don’t fit neatly into a formula – like whether your employer would have promoted you, how long your recovery will actually take, or what vocational options are realistically available given your specific limitations.
