How to Calculate Lost Wages After an Accident

The formulas, the documentation, and the categories most people forget to include.

Lost wages are usually the second-largest piece of an injury settlement — after medical bills. They're also the piece most claimants undercount. Here's how to get the number right.

The basic formula

Hourly worker: hourly rate × hours missed per pay period × pay periods missed.

Salaried worker: (annual salary ÷ 2,080) × hours missed.

Self-employed: average weekly net income from the prior 12 months × weeks missed. Use Schedule C, 1099s, and bank deposits.

What counts as lost wages (most people miss these)

  • Base hourly or salary income
  • Overtime you regularly worked
  • Tips and commissions (use tax records)
  • Bonuses you would have earned
  • Sick days and PTO you had to use (these are recoverable)
  • Missed business opportunities (contractors, sales reps)
  • Reduced earning capacity if you can't return to the same role
  • Lost benefits (health insurance contributions, 401(k) match)

Documentation insurers will demand

  • Letter from employer confirming dates missed and rate of pay
  • Recent pay stubs (8 weeks pre-accident is standard)
  • W-2s or 1099s for the prior 2 years
  • Tax returns for the prior 2 years
  • Doctor's notes restricting you from work
  • For self-employed: profit/loss statements, client invoices

Future lost earning capacity

If your injury permanently affects your ability to work — surgeon who can no longer stand for long periods, electrician with a permanent hand injury — your claim should include a vocational expert's projection of future earnings loss. This is often a six-figure component of serious injury settlements.

When legal help may make sense

If you cannot return to the same work, or the insurer disputes your wage records, an attorney review may make sense.
