How Illinois TTD is calculated
The ordinary temporary total disability rate is 66 2/3% of average weekly wage. Illinois then applies the TTD maximum for the injury-date period and a minimum based on the combined number of a spouse and children. The minimum cannot make the payment exceed the worker’s AWW.
| Injury-date period | TTD maximum |
|---|---|
| January 15–July 14, 2026 | $2,008.60 |
| July 15, 2026–January 14, 2027 | $2,045.63 |
2026 TTD minimum schedule
| Spouse and/or children | Scheduled minimum |
|---|---|
| 0 | $400 |
| 1 | $460 |
| 2 | $520 |
| 3 | $580 |
| 4 or more | $600 |
The official IWCC table states that the minimum is the employee’s AWW or the scheduled amount, whichever is lower. Dependents do not increase an otherwise applicable two-thirds result unless the scheduled minimum is higher.
Temporary partial disability
When an eligible worker performs modified or other work for less than full-duty earning capacity, Illinois law sets TPD at two-thirds of the difference between what the worker would earn in full performance and gross earnings in the modified or other job.
The calculator uses entered AWW as a practical proxy for full-duty weekly earning capacity. A disputed AWW, overtime pattern, concurrent job, post-injury earning capacity, or work restriction requires claim-specific review.
Waiting period and limitations
If temporary total incapacity lasts more than three working days, TTD begins on the fourth day. If incapacity continues for 14 days or more from the accident, compensation begins the day after the accident. The calculator estimates a weekly rate only; it does not count working days or determine whether the first three days become payable.
Is this a settlement calculator?
No. It estimates one weekly TTD or TPD amount and does not value permanent disability, wage differential, medical care, penalties, settlement terms, or attorney fees.
Why does the maximum change in July?
The IWCC publishes new SAWW-based maximums every January 15 and July 15. The injury-date period controls the selection in this tool.
Does a dependent always raise TTD?
No. Dependents affect the statutory minimum. If two-thirds of AWW is already above that minimum, the ordinary calculation remains in place, subject to the maximum.
