The cap is the number that decides your cheque
Almost every explanation of workers' compensation starts and ends with "two thirds of your wages." That is true, and it is also the least useful part of the sentence. Missouri's own wording carries the qualifier that matters: temporary total disability pays "66 2/3% of the injured worker's average weekly wage, not to exceed a maximum amount set by the law." The maximum is where the real arithmetic happens.
For the displayed Missouri period, a $3,000 weekly wage produces $2,000 at two thirds, but the $1,294.71 cap reduces the modeled replacement rate to about 43%. At $1,200, the model gives $800. At a very low positive wage, the $40 minimum can instead raise the result. These examples assume eligibility and do not model partial-disability earnings or offsets.
The presets cover Missouri temporary total disability for July 1, 2026 through June 30, 2027 and California temporary disability for 2026, plus dated presets for Florida, Georgia, New Jersey, New York, North Carolina, Texas and Virginia; each state's figures and sources are on its own page, linked below. Only Missouri's waiting period is modelled. Missouri has a $40 weekly minimum under section 287.170; California lists a $264.61 minimum and $1,764.11 maximum. Confirm the applicable injury date, benefit type and any adjustments with the administrator. These presets are not rates for every injury year.
Two thirds of gross is more than it sounds
The replacement rate looks harsher than it is, because the comparison is unfair. Your wage was taxed; the benefit is not. IRS Publication 525 states that "amounts you receive as workers' compensation for an occupational sickness or injury are not included in your income," with a narrow exception where state law treats part of the payment as a pension based on years of service.
For a household budget, compare the estimated benefit with actual take-home pay and essential expenses. Do not infer a universal net-pay replacement percentage from a gross-wage rule. Return-to-work decisions depend on medical restrictions and available work, not on this calculation.
The first days you miss
Nearly every state has a waiting period, and most make it retroactive if you are off long enough. Missouri does not pay "for the first three business days or less of disability," but adds that "if you are unable to work for more than 14 days the 'three-day waiting period' will be paid." Both numbers — the wait and the threshold that claws it back — are set by state law and vary widely.
Missouri’s threshold can change the timing of payments. The tool approximates a partial week using one seventh of the weekly rate per day and does not reconstruct a work calendar. Confirm the actual waiting days and payment period with the administrator. Follow medical advice and work restrictions rather than changing a return date to fit this estimate.
