Overtime Calculator

Pay and hours
Overtime rules

Hours after which overtime rate applies. US standard is 40.

Enter your hourly rate and hours worked to calculate overtime pay.

Overtime pay adds up fast - but so do payroll errors if the calculation is wrong. Enter your hourly rate, total hours worked, and the threshold after which overtime kicks in. The calculator splits the week into regular and overtime hours, applies the correct multiplier, and shows your total gross pay. Adjust the threshold and rate to match your employment contract or local rules.

Overtime calculations are estimates based on the inputs you provide. Overtime rules, thresholds, and multipliers vary by country, state, employer, and employment contract. This tool does not constitute legal or payroll advice. Verify the rules that apply to your situation with your employer or a qualified advisor.

How to use this tool

  1. 1Enter your regular hourly rate.
  2. 2Enter total hours worked this week.
  3. 3Set the overtime threshold - the number of hours per week after which overtime pay applies. The standard in many countries is 40 hours, but check your contract or local law.
  4. 4Set the overtime multiplier: 1.5x (time and a half) is most common; 2x (double time) applies for some shifts or holiday work. You can also enter a custom multiplier.
  5. 5Read regular hours, overtime hours, regular pay, overtime pay, and total gross pay.

Formula used

Regular hours = minimum(hours worked, overtime threshold). Overtime hours = maximum(hours worked - overtime threshold, 0). Regular pay = regular hours x hourly rate. Overtime pay = overtime hours x hourly rate x overtime multiplier. Total gross pay = regular pay + overtime pay.

Example

Standard weekly overtime at 1.5x

Hourly rate: 18. Hours worked: 48. Threshold: 40. Multiplier: 1.5x. Regular hours: 40. Overtime hours: 8. Regular pay: 40 x 18 = 720. Overtime pay: 8 x 18 x 1.5 = 216. Total gross pay: 936.

Holiday shift at double time

Hourly rate: 22. Hours worked: 35 (all holiday hours). Threshold: 0 (entire shift is overtime). Multiplier: 2x. Regular hours: 0. Overtime hours: 35. Regular pay: 0. Overtime pay: 35 x 22 x 2 = 1,540. Total gross pay: 1,540.

Common use cases

  • Employees checking their payslip to verify overtime has been calculated correctly
  • Employers and payroll managers calculating weekly gross pay for hourly staff
  • Freelancers and contractors billing for a week with extra hours at an agreed overtime rate
  • Workers comparing the financial impact of working overtime versus taking time off in lieu
  • HR managers quickly checking overtime costs before approving extra hours

Common mistakes

  • Using the wrong overtime threshold - the legal threshold varies by country and state; always check whether yours is 40 hours per week, 8 hours per day, or defined by your contract.
  • Applying overtime to the base rate only and forgetting shift differentials - if you receive a premium for night shifts, overtime should be calculated on the total effective rate including the differential.
  • Confusing gross and net pay - this calculator shows gross pay before tax and deductions. Your take-home will be lower after income tax and payroll deductions.

Frequently asked questions

What is the standard overtime threshold?

In the United States under FLSA, most non-exempt employees are entitled to overtime for hours over 40 per week at 1.5x their regular rate. In the UK, there is no statutory right to overtime pay unless your contract provides it, though pay must not fall below minimum wage. Australia requires overtime at 1.5x after 38 hours/week, rising to 2x after specified limits. Always check your employment contract and local law.

What is the difference between 1.5x and double time?

Time and a half (1.5x) means you earn your regular rate plus 50% extra for each overtime hour. Double time (2x) means you earn twice your regular rate. Many employment contracts offer 1.5x for standard overtime and 2x for work on public holidays or excessive hours. Some have a tiered system: 1.5x for the first N overtime hours, then 2x beyond that.

Does this calculate daily overtime?

This calculator uses a weekly overtime threshold. Some jurisdictions (e.g. California) require overtime for hours worked over 8 in a single day, not just over 40 per week. For daily overtime, calculate each day separately using a threshold of 8 hours and sum the results.

Is gross pay the same as what I will be paid?

No. Gross pay is before income tax, national insurance or social security, pension deductions, and any other withholdings. Your net (take-home) pay will be lower. Use gross pay for payroll calculations and your payslip for actual take-home verification.

Is my data stored or uploaded?

No. All calculations run in your browser. Nothing is sent to any server.
