How to calculate overtime pay under the FLSA

Updated 2026-11-12 · By the Assistlify team · AI-assisted, every fact linked to its source below

Under the FLSA, overtime pay is at least 1.5 times the employee's regular rate for every hour over 40 in a workweek. Example: 46 hours at $18.00 pays 40 × $18.00 = $720.00 plus 6 × $27.00 = $162.00, for $882.00. The regular rate includes most pay earned that week, not only the base hourly wage.

The three federal rules that decide the number

  1. 40 hours per workweek. Non-exempt employees get at least 1.5× their regular rate for hours worked over 40 in a workweek (DOL Fact Sheet #23).
  2. Each workweek stands alone. A workweek is a fixed, recurring 168-hour period that can start on any day and hour. Hours cannot be averaged: 30 hours one week and 50 the next still means 10 overtime hours in the second week (29 CFR 778.104, 778.105).
  3. All hours for the employer count. The employer must total all hours the employee works for it in the workweek, even across unrelated job assignments (29 CFR 778.103). Hours at your second store are added to hours at the first.

Example 1: one hourly rate

Straight time40 × $18.00$720.00
Overtime rate$18.00 × 1.5$27.00/hour
Overtime pay6 × $27.00$162.00
Total$720.00 + $162.00$882.00

Example 2: two jobs at two rates in one week

When an employee works two kinds of work at different rates in one workweek, the regular rate is the weighted average: total earnings divided by total hours (29 CFR 778.115).

  1. 30 hours as cashier at $15.00 = $450.00
  2. 15 hours as shift lead at $19.00 = $285.00
  3. Straight-time earnings: $735.00 for 45 hours
  4. Regular rate: $735.00 ÷ 45 = $16.3333
  5. Overtime premium: 5 hours × ($16.3333 ÷ 2) = 5 × $8.1667 = $40.83 (all 45 hours were already paid at straight time, so only the extra half is added)
  6. Total pay: $735.00 + $40.83 = $775.83

Example 3: one employee, two locations

22 hours at Store A plus 24 hours at Store B at $17.00 = 46 hours. Overtime is 6 hours, even though neither store went over 40: 46 × $17.00 = $782.00 plus 6 × $8.50 = $51.00 premium, total $833.00. More on this in reducing overtime across locations.

What goes into the regular rate

What the FLSA does not require

Overtime cannot be waived by agreement. A rule that overtime must be pre-approved does not cancel the duty to pay for overtime actually worked (Fact Sheet #23). Work that is not requested but is "suffered or permitted" is work time (29 CFR 785.11).

States with different overtime thresholds

As listed by the US DOL state minimum wage table (updated November 5, 2026):

StatePremium pay after
Alaska8 hours a day or 40 a week; not applicable to employers of fewer than 4 employees
California1.5× after 8 hours a day, 40 a week and the first 8 hours on the 7th day; 2× after 12 hours a day and after 8 hours on the 7th day
Colorado12 hours a day or 40 a week
Kentucky40 a week; 1.5× on the 7th day when the employee works all 7 days
Nevada8 hours a day for employees earning less than 1.5× the state minimum wage; 40 a week for all
Minnesota48 hours a week under state law (the federal 40-hour rule still applies to FLSA-covered employers)

Per-state pages are in labor laws by state. Exempt salaried staff are covered in exempt vs non-exempt.

Questions

How do I calculate time and a half?

Multiply the regular rate by 1.5 and by the hours over 40 in the workweek. At $18.00, 6 overtime hours pay 6 × $27.00 = $162.00.

Can I average hours over two weeks to avoid overtime?

No. 29 CFR 778.104 says each workweek stands alone; 30 hours one week and 50 the next means 10 overtime hours in the second week.

Do hours at two of my stores add up for overtime?

Yes. 29 CFR 778.103 requires the employer to total all hours the employee works for it in the workweek.

Is weekend or holiday work paid at overtime?

Not under the FLSA unless total hours exceed 40 in the workweek; state law or your own policy may add a premium.

What if an employee works overtime I did not approve?

You still pay it. Fact Sheet #23 says an announcement that unapproved overtime will not be paid does not remove the right to it.
