Average Weekly Wage (AWW)
The number that determines everything
Your AWW is the foundation of virtually every monetary benefit in your BWC claim. An error in that one number silently reduces every check you receive — for the entire life of your claim.
Your Average Weekly Wage (AWW) is the foundation of virtually every monetary benefit in your BWC claim. An error or omission in that one number silently reduces every check you receive — for the entire life of your claim.
The AWW is calculated using your wages from the 52 weeks prior to your injury date across all employers. If you worked multiple jobs during that year, all wages must be counted. If you worked for your current employer for less than a year, wages from prior employers fill in the remaining weeks. If you were unable to work for the full 52 weeks prior to your injury date you may qualify for ‘special circumstances’ in the setting of your AWW. Don’t accept the BWC calculation of your AWW if you did not work at your injury employer’s employ for the full 52 weeks prior to the injury!
Real example: A worker injured after 6 months with a new employer had a BWC-calculated AWW of $576.93/week. After Mike audited the claim and added wages from two prior employers during the same 52-week period, the correct AWW was increased to $769.23 — a difference of $192.30 per week. Because TTD is paid at 66⅔% of AWW, this error meant approximately $128 less per week — or over $26,000 across a 4-year TTD period.
Never assume your AWW is correct. Have a certified specialist review the calculation before accepting any BWC order setting your compensation rate.
How AWW is calculated in Ohio
Under R.C. § 4123.61, your Average Weekly Wage is determined by dividing your total gross earnings from the 52 weeks immediately preceding your date of injury by 52. The calculation follows a straightforward process, but the details matter enormously:
- Gather wage records from all employers. The BWC pulls payroll data for the 52-week lookback period. If you held more than one job during that time, wages from every employer must be included.
- Total the gross earnings. This includes regular wages, overtime, bonuses, commissions, tips, and certain fringe benefits. Pre-tax gross pay is used — not net or take-home pay.
- Divide by 52. The resulting figure is your AWW, which the BWC then uses to calculate your compensation rate (typically 66⅔% of AWW for TTD benefits, subject to statutory minimums and maximums).
When you worked fewer than 52 weeks before the injury — because you recently started a new job, returned to the workforce, or were between employers — the calculation becomes more complex. The BWC may use wages from prior employers to fill in the remaining weeks. If that still does not produce a full 52 weeks of earnings, special-circumstances provisions under R.C. § 4123.61 may apply.
Seasonal and irregular employment adds another layer of difficulty. A construction worker who earns $1,500 per week during the busy season but works only 36 weeks per year will have a much lower AWW than their peak earning rate suggests. In some cases, an argument can be made for a comparable-employee wage or an adjusted calculation that better reflects true earning capacity.
What counts as wages for AWW purposes
Ohio law requires the BWC to include all forms of remuneration when calculating your AWW — not just base hourly or salary wages. The following must be counted:
- Overtime pay — all overtime premiums earned during the 52-week period, including mandatory and voluntary overtime
- Bonuses — production bonuses, performance bonuses, sign-on bonuses, and holiday bonuses that were paid during the lookback period
- Commissions — commission-based earnings for sales workers, delivery drivers, and similar roles
- Tips — reported tip income for restaurant, hospitality, and service workers
- Second and third job wages — earnings from all concurrent employers during the 52-week period, not just the employer where the injury occurred
- Fringe benefits — in certain circumstances, the cash value of employer-provided fringe benefits may be includable
- Union supplemental pay — supplemental wages, per diem payments, or allowances paid through a union or employer fund
Key point: The burden often falls on the injured worker to prove that the BWC’s wage data is incomplete. If your employer failed to report overtime, did not include bonus payments, or neglected to account for a second job, the BWC will simply use whatever incomplete data it has. That is why an independent audit of your AWW is so critical.
Common AWW errors that cost injured workers thousands
In Mike’s nearly 50 years of practice, AWW errors are one of the most frequent — and most costly — mistakes in BWC claims. These errors compound over time because every benefit payment is derived from the AWW. Here are the most common problems:
Missing wages from secondary employers
When an injured worker holds two or more jobs, the BWC frequently calculates the AWW using only the wages from the employer where the injury occurred. Wages from every employer during the 52-week lookback must be included. The $26,000 error in the example above resulted from exactly this mistake — two prior employers’ wages were omitted.
Overtime being excluded
Some employers report only base wages to the BWC, leaving overtime premiums out of the payroll data. For a factory worker earning $22/hour base with 10 hours of weekly overtime at time-and-a-half, that exclusion understates weekly earnings by $330 — which translates to roughly $220 less per week in TTD benefits, or over $11,400 per year.
Recent raises not reflected
If you received a significant raise partway through the 52-week lookback period, your AWW will be dragged down by the earlier, lower wage rate. While the statute requires using actual earnings, in some cases a special-circumstances argument can be made — particularly if you were promoted to a new position with substantially different duties and compensation.
Seasonal workers with variable income
A landscaping company employee earning $1,200/week from April through November but laid off during winter months will have an AWW that includes 16–20 weeks of zero earnings. That drags the annual average well below their actual working wage. If the injury occurred during peak season, the worker’s TTD check will feel drastically low compared to what they were actually earning.
Another real-world scenario: A nurse working three 12-hour shifts per week at a hospital ($38/hour) also picked up two shifts per month at a staffing agency ($45/hour). When she was injured at the hospital, the BWC calculated her AWW using only hospital wages — $1,368/week. After adding the agency shifts, her correct AWW was $1,638/week. At the 66⅔% TTD rate, she was being underpaid by $180 per week.
Scenario: A truck driver received a $3/hour raise six weeks before his injury. His new rate was $28/hour for 50–55 hours per week, but the BWC used the blended 52-week average that included 46 weeks at his old $25/hour rate. The difference: approximately $75/week in TTD benefits. Over a 2-year claim, that single error cost him nearly $7,800.
Special circumstances AWW
R.C. § 4123.61 recognizes that a straight 52-week average does not always produce a fair result. When an injured worker has not been employed for the full 52 weeks before the injury, special-circumstances provisions allow for alternative calculation methods:
New employees
If you started your job only weeks or months before the injury, dividing your limited earnings by 52 produces an artificially low AWW. In these cases, the BWC may use wages from prior employers to fill in the remaining weeks, or the Industrial Commission may calculate the AWW based on what a similarly situated employee in the same job would have earned over a full year.
Workers returning to the workforce
If you had been out of the labor force — due to illness, caregiving responsibilities, incarceration, or any other reason — and were injured shortly after returning, the standard 52-week lookback would include long stretches of zero wages. Special-circumstances provisions allow for an adjusted calculation that reflects your actual earning capacity at the time of injury.
Apprentices and trainees
Apprentices often earn progressively higher wages as they advance through their program. An apprentice injured in month four may have an AWW based on their starting wage, even though they were on track for scheduled raises. The Industrial Commission has discretion to account for this progression when setting the AWW under special-circumstances provisions.
Workers who changed jobs mid-year
If you left a lower-paying job for a higher-paying one shortly before the injury, your 52-week average will be weighted toward the old, lower wage. Conversely, if you took a pay cut, the average may overstate your earnings at the time of injury. In either case, the special-circumstances analysis under R.C. § 4123.61 gives the Commission flexibility to set an AWW that fairly represents the injured worker’s true earning capacity.
Don’t accept the default calculation. If you did not work at your injury employer for the full 52 weeks prior to the injury, the BWC’s initial AWW is almost certainly wrong. Contact a certified specialist to review whether a special-circumstances application should be filed.
Full Weekly Wage (FWW) vs. Average Weekly Wage (AWW)
One of the most commonly confused aspects of Ohio workers’ compensation is the distinction between Full Weekly Wage (FWW) and Average Weekly Wage (AWW). They are two different calculations, used at different stages of your claim:
Full Weekly Wage (FWW)
Calculated from the 6 weeks immediately before your injury. Used to set your TTD compensation rate for weeks 1 through 12. This shorter lookback typically produces a higher figure because it captures your most recent earnings.
Average Weekly Wage (AWW)
Calculated from the 52 weeks before your injury. Takes over as the basis for your TTD rate starting at week 13 and is used for all subsequent benefit calculations, including wage loss, PPD, and settlement valuations.
The transition from FWW to AWW at week 13 often results in a reduction in your bi-weekly check — sometimes a significant one. If you recently started a higher-paying job, your 6-week FWW may be substantially higher than your 52-week AWW (which includes time at a lower-paying prior job). Many injured workers are blindsided by this drop and mistakenly believe the BWC made an error, when in fact it is a built-in feature of the statute.
However, the opposite also occurs: if your AWW is higher than your FWW — for example, because you recently reduced hours or changed to a lower-paying role — your rate should increase at week 13. If the BWC does not make this adjustment, you are being underpaid.
Either way, both the FWW and AWW calculations should be independently verified. Mike reviews both figures in every claim he handles to ensure the injured worker is receiving the correct rate at every stage of the claim.
