How to Calculate Overtime Pay

Overtime pay is where paychecks most often go wrong, and where each mistake costs the most. The good news is that the math is straightforward once you know your rule. Here's how to calculate overtime pay by hand, with examples, so you can check your own check.

The basic overtime formula

Overtime pay = overtime hours x hourly rate x overtime multiplier.

Most overtime is paid at 1.5 times your regular rate, often called time-and-a-half. Some situations pay double time (2x).

Know your overtime rule first

Under U.S. federal law, most hourly employees earn overtime for hours over 40 in a workweek. Some states add daily overtime. California, for example, generally requires overtime after 8 hours in a day and double time after 12. Your employer or union contract may be more generous.

Rules depend on your state and job, so check your state labor department or employee handbook. This post is general information, not legal advice.

How to calculate weekly overtime

Step 1: Add up your hours for the workweek

Use decimal hours. If you need help, see how to calculate hours worked and how to convert time to decimal.

Step 2: Split regular and overtime hours

Hours up to 40 are regular. Everything above 40 is overtime.

Step 3: Calculate each part

Example: $18 an hour, 46.5 hours this week.

  • Regular pay: 40 x $18 = $720
  • Overtime rate: $18 x 1.5 = $27
  • Overtime pay: 6.5 x $27 = $175.50
  • Total gross pay: $895.50

How to calculate daily overtime

If your state or employer pays daily overtime, check each day first. Example with overtime after 8 hours a day at $20 an hour, and a 10-hour Monday:

  • Regular: 8 x $20 = $160
  • Overtime: 2 x $30 = $60
  • Monday total: $220

When both daily and weekly rules apply, hours already counted as daily overtime usually aren't counted again toward weekly overtime. This is where hand math gets confusing fast.

Things that change your overtime rate

  • Raises mid-week. Each hour should use the rate in effect when you worked it.
  • Two rates at one employer. Overtime may be based on a weighted average of both.
  • Some bonuses. Certain bonuses can raise the regular rate used for overtime.
