How it works
For each week, regular hours = the lower of your hours and the overtime threshold; overtime hours = the rest. Expected pay = regular hours × rate + overtime hours × rate × multiplier. Stub pay = regular hours paid × rate + overtime hours paid × the stub's overtime rate. Difference = expected − stub.
Worked examples
- You worked 45 hours in one week at $20 an hour, and the stub shows 45 regular hours. Expected: 40 × $20 + 5 × $30 = $950. Paid: $900. The stub is $50 short.
- Two weeks of 50 and 30 hours, paid as 80 regular hours at $20: expected $1,700, paid $1,600, so $100 short, because overtime is counted per week.
- You worked 40 hours and the stub shows 38 at $15 an hour: 2 hours, $30, are missing.
Common questions
How do I check if my paycheck is right?
Add up the hours you worked each week, then compare them with the regular and overtime hours on your pay stub, and check that the rates multiply out to the gross pay. This checker does those steps for you.
Can my employer average hours over two weeks to avoid overtime?
Not under US federal law: the Department of Labor says averaging of hours over two or more weeks is not permitted. Each workweek stands alone, even if you are paid every two weeks.
What should I do if I was underpaid?
Keep your own time records, ask payroll in writing for a correction, and keep their reply. In the US you can contact the Wage and Hour Division on 1-866-487-9243.
Why doesn't my gross pay equal hours × rate?
Gross pay can include tips, bonuses, shift differentials, holiday pay or other items. Ask payroll for a line-by-line breakdown.
