An overtime calculator figures out gross pay when some hours are paid at a premium rate. Enter your regular hours, overtime hours, hourly rate and the overtime multiplier (usually 1.5x, or "time and a half") to see regular pay, overtime pay and total gross pay for the week, plus monthly and annual projections.
Your hours and rate
Standard overtime is 1.5x ("time and a half"). Some holidays or contracts pay 2x double-time.
Pay breakdown
How is overtime pay calculated?
Multiply overtime hours by your hourly rate times the overtime multiplier, then add regular pay. At $20/hr with 5 OT hours at 1.5x: (40 x $20) + (5 x $20 x 1.5) = $800 + $150 = $950 gross.
The multiplier is usually 1.5 ("time and a half") for hours over 40 per week under US federal law, but contracts and states can set higher rates.
What is time and a half?
Time and a half means 1.5 times your normal hourly rate. If you earn $20/hour, time and a half is $30/hour for each overtime hour worked.
Double-time is 2x your rate ($40/hour on a $20 base). This calculator lets you set any multiplier to match your policy.
When does overtime kick in?
Under the US Fair Labor Standards Act, non-exempt employees earn overtime for hours worked beyond 40 in a single workweek. Some states add daily overtime rules.
Salaried exempt employees, independent contractors and some other categories are not covered. Check your state labor rules if you are unsure.
Frequently asked questions
What multiplier should I use?
Use 1.5 for standard US overtime ("time and a half"). Use 2.0 for double-time shifts, or any custom multiplier your employer or contract specifies.
Does this include taxes?
No. The result is gross pay before federal and state taxes, Social Security and Medicare. Use the paycheck calculator for a take-home estimate.
Are monthly and annual figures guaranteed?
No. They project your current weekly pace across the year (weekly x 52). Real overtime varies week to week, so treat them as planning figures.
Can I use this for double-time holiday pay?
Yes. Set the overtime multiplier to 2 and enter the holiday hours as overtime hours to see double-time pay.
Is my pay data uploaded anywhere?
No. All calculations run locally in your browser. Nothing is sent to any server.
