How to Calculate Overtime Pay (FLSA Rules + Examples)

By Jorge Sanchez · April 20, 2026 · 5 min read

Bottom line: If you earn $20/hr and work 45 hours, your check is: (40 × $20) + (5 × $30) = $950. The 5 overtime hours are paid at 1.5× rate.

Under the Fair Labor Standards Act (FLSA), most hourly workers must receive overtime pay — 1.5 times their regular rate — for every hour worked beyond 40 in a workweek. Here's exactly how it's calculated.

The Overtime Formula

Regular Pay = Regular Rate × 40 hours

Overtime Pay = Regular Rate × 1.5 × Overtime Hours

Total Pay = Regular Pay + Overtime Pay

Salaried Employees: How to Calculate Your Regular Rate

If you're salaried but non-exempt (eligible for overtime), your regular hourly rate is:

Regular Rate = Weekly Salary ÷ 40 hours

Example: You earn $52,000/year = $1,000/week. Your regular rate = $1,000 ÷ 40 = $25/hr. If you work 50 hours in a week, you earn an additional 10 × $12.50 = $125 in overtime (the "half" portion only, since the straight-time is already covered by your salary).

Who Is Exempt from Overtime?

The following are typically exempt from FLSA overtime requirements:

Note: many states have stricter rules. California uses an 8-hour/day rule in addition to the 40-hour/week rule.
