Formula / logic

Total pay = (Regular hours × hourly rate) + (Overtime hours × hourly rate × OT multiplier).

Worked example

At $20/hr with 40 regular hours and 5 overtime hours at 1.5×: regular pay $800 + overtime pay $150 = $950 total.

Under the FLSA, non-exempt employees are generally owed overtime for any hours worked beyond 40 in a single work week.

1.5× ("time-and-a-half") is the most common rate; some employers or holidays use 2× ("double time") instead.
