How Indiana Workers Compensation Is Calculated
Indiana uses a specific formula to determine workers compensation benefits, anchored to the employee's average weekly wage (AWW). Unlike some states that use a fixed statutory cap, Indiana adjusts its maximum benefit rate annually based on the statewide average weekly wage. Understanding this calculation is essential for any Indiana worker who has suffered a workplace injury.

Average Weekly Wage (AWW)
The AWW is the cornerstone of the Indiana calculation. It is derived by dividing the employee's total earnings during the 13 weeks immediately preceding the injury by 13. The statute excludes certain types of income, such as overtime earnings, to establish a baseline that reflects normal earnings rather than a temporary spike. If the employee worked less than 13 weeks, the calculation uses the actual period worked.
Temporary Total Disability (TTD)
For injuries that temporarily prevent an employee from working, Indiana pays TTD at two-thirds of the AWW. The maximum weekly benefit rate is capped and adjusted each year. For 2025, the maximum TTD rate is $780, but the actual weekly check depends on the employee's pre-injury earnings.
Impairment and Permanent Partial Disability (PPD)
Once the employee reaches maximum medical improvement, a rating is assigned using the American Medical Association Guides. Indiana uses a schedule of impairments for specific body parts. PPD benefits are calculated by multiplying the impairment percentage by the number of weeks specified for that body part in the state schedule, then multiplying by the weekly compensation rate.
Maximum Medical Improvement and Settlement
The Indiana Workers Compensation Board oversees the calculation and approval of settlements. A lump sum or structured settlement must reflect the correct AWW, the appropriate impairment rating, and any applicable surcharge for disputes. Errors in the AWW calculation are among the most common reasons for claim disputes.
Key Factors That Influence the Calculation
- Pre-injury earnings: Wages, bonuses, and certain fringe benefits included in the 13-week lookback.
- Date of injury: The maximum weekly rate is locked to the year the injury occurred.
- Body part affected: The schedule of impairments dictates the weeks of compensation allowed.
- Disputed claims: An evidentiary hearing may result in a surcharge added to the weekly rate.
Comparison of Indiana Benefit Components
| Benefit Type | Calculation Basis | Maximum Weekly Rate (2025) |
|---|---|---|
| TTD | Two-thirds of AWW | $780 |
| PPD | Impairment % × scheduled weeks × rate | Varies by AWW |
| Death Benefits | Two-thirds of AWW, subject to cap | $780 |
When to Seek Guidance
The Indiana workers compensation calculation involves specific statutory formulas and annual rate adjustments. If an employee's AWW is disputed or if the employer is self-insured, the calculation may become complex. Reviewing the injury date and the applicable maximum rate with a qualified professional can help ensure the correct benefit amount is received.
