Montana Overtime Calculator
Enter daily hours and a straight-time hourly rate. The calculator applies the verified weekly threshold from the registry and adds only the extra overtime premium, so hours are not paid twice.
Who this rate applies to: Businesses not covered by FLSA with gross annual sales of $110,000 or less may pay $4.00/hr; FLSA-covered employees must receive the greater of federal or Montana minimum wage. No tip credit, meal credit, or training wage.
Source The headline rate may not apply to every worker. Montana has worker- or employer-class exceptions in the registry. Use the hourly-rate field for the rate that applies to the worker and verify coverage before relying on the estimate.
Worked example
Weekly overtime calculation
A Montana employee works 45 hours at $10.85/hr\nWeekly overtime hours = 45 − 40 = 5\nOvertime premium = 5 × regular rate × 0.50
What this does not determine
- Whether a worker is exempt from overtime under state or federal law.
- Whether an industry-specific threshold, agricultural rule, residential rule, collective-bargaining agreement, or public-contract rule changes the result.
- Whether tips, commissions, bonuses, shift differentials, or multiple hourly rates were included correctly in the regular rate.
- Whether local minimum-wage ordinances or special worker classes change the straight-time rate used in the calculator.
- Penalties, wage-claim deadlines, interest, attorneys' fees, or agency filing strategy.

Common questions
Does Montana have its own state overtime statute?
Yes. Montana Wage and Hour Act, § 39-3-406 MCA, requires time-and-a-half for hours over 40 in a workweek. Montana has a standalone state overtime rule that gives workers a state-law remedy in addition to the federal FLSA.
What is the $4.00 Montana minimum wage for small businesses about?
Montana Code § 39-3-409 allows businesses NOT covered by the federal FLSA with gross annual sales at or below $110,000 to pay $4.00/hr. This does not affect overtime: § 39-3-406 MCA still requires time-and-a-half after 40 hours for covered workers. The $4.00 rate is a minimum wage provision only, not an overtime exemption.
Does Montana have daily overtime?
No. Montana's § 39-3-406 MCA requires overtime only after 40 hours in a workweek. There is no daily overtime trigger in Montana. A long shift earns straight time for all hours unless the week's total exceeds 40.
How does Montana's overtime compare to Wyoming's?
Montana has a state overtime statute at § 39-3-406 MCA: time-and-a-half after 40 hours. Wyoming has no state overtime statute for private workers — all overtime rights for Wyoming workers come from the federal FLSA. Montana's $10.85 CPI-indexed minimum wage also far exceeds Wyoming's sub-federal state rate of $5.15.
