How the Texas Overtime Calculator works
Texas does not have its own state overtime law. Overtime pay for hourly employees in Texas is governed entirely by the federal Fair Labor Standards Act (FLSA): non-exempt workers must be paid 1.5 times their regular hourly rate for every hour worked beyond 40 in a single workweek. This calculator applies that exact rule to your hourly rate and hours to show your regular pay, overtime pay, total weekly gross pay, and a projected annual figure.
The FLSA overtime formula
For a regular hourly rate R and hours worked H in one workweek:
Regular pay = R x min(H, 40)
Overtime hours = max(0, H − 40)
Overtime pay = Overtime hours x R x 1.5
Total weekly pay = Regular pay + Overtime pay
The 1.5 multiplier is the federal minimum; this calculator lets you adjust it in case your employer or a collective bargaining agreement pays a higher rate (such as double time), but 1.5x is the standard, legally required baseline in Texas.
Worked example
Take an $18/hour employee who works 45 hours in a week. The first 40 hours are paid at the regular rate: 40 x $18 = $720. The remaining 5 hours are overtime, paid at 1.5 x $18 = $27/hour: 5 x $27 = $135. Total gross pay for the week is $720 + $135 = $855. If that pattern held for all 52 weeks of the year, projected annual gross pay would be about $44,460.
What moves the overtime total
- Hours over 40: only hours beyond the 40-hour weekly threshold count as overtime — working 39 hours produces no overtime at all, no matter how the hours are distributed across days.
- Hourly rate: both regular and overtime pay scale directly with the hourly rate, so a raise increases the overtime premium along with the base rate.
- Overtime multiplier: 1.5x is the FLSA minimum. Some employers voluntarily pay more (for example, 2x on Sundays or holidays), which this calculator can model by raising the multiplier input.
Who is exempt from overtime
Not every worker qualifies for overtime. The FLSA exempts certain salaried employees in executive, administrative, and professional roles who meet specific duties and salary-level tests, as well as some outside sales and computer professionals. This calculator assumes a non-exempt hourly employee covered by the standard 40-hour rule; if you are unsure whether your role is exempt, that classification depends on your actual job duties, not your job title.
