Overtime Pay Calculator

How overtime pay is calculated

Overtime pay is usually your hourly rate × overtime multiplier × overtime hours. In many places the multiplier is 1.5 (time and a half) for hours beyond 40 per week. Regular pay is hourly rate × regular hours. Total pay = regular pay + overtime pay (and, if applicable, double-time pay).

Regional overtime notes (US, UK, EU)

US: The Fair Labor Standards Act (FLSA) generally requires time-and-a-half (1.5×) for hours over 40 per workweek for non-exempt employees. Some states have daily overtime (e.g. California: OT after 8 hours/day or 40/week). UK: The 48-hour weekly cap (opt-out possible) is a reference; overtime rates are typically set by contract, often 1.5×. EU: The Working Time Directive references a 48-hour average; member states and sectors set thresholds and rates. Use this calculator’s presets or custom threshold to approximate your jurisdiction.

Daily overtime explained

Some jurisdictions and employers pay overtime based on daily hours (e.g. after 8 hours in a day) in addition to or instead of weekly. In daily mode, this tool assumes the same hours each day and applies your chosen daily OT and double-time thresholds. Use it as an estimator only; actual rules vary by location and contract.

How to calculate overtime after 40 hours

To calculate overtime after 40 hours: (1) Take your hourly rate. (2) Multiply by your overtime rate (e.g. 1.5 for time and a half). (3) Multiply by the number of overtime hours. Add that to your regular pay (hourly rate × 40). Example: $20/hour, 45 hours → regular $800 (40×20) + overtime $150 (5×20×1.5) = $950 total gross.

Our overtime calculator weekly pay tool does this automatically. Turn on “automatically calculate overtime after 40 hours” and enter your total hours and rate to get an instant estimate.

Overtime vs double time explained

Overtime usually means hours beyond the standard week (e.g. 40), often paid at 1.5×. Double time means 2× your rate and may apply to holidays, Sundays, or hours beyond a second cap (e.g. after 12 hours in a day). In this calculator, double-time hours are a subset of your overtime hours: you enter total overtime, then specify how many of those are paid at 2×. The rest are paid at your chosen multiplier (e.g. 1.5×).

Not all employers offer double time. Use the overtime wage estimator above to model both scenarios and compare paychecks.

Pay frequency

Pay can be quoted weekly, biweekly (every two weeks), monthly, or yearly. This calculator uses a weekly baseline; biweekly = weekly × 2, monthly ≈ weekly × 4.33, yearly = weekly × 52. Select your pay frequency above to see period pay and equivalent weekly amount.

Gross vs net pay

Gross pay is your pay before taxes and deductions (e.g. tax, insurance, retirement). Net pay is take-home after those are subtracted. This tool shows estimated gross pay; you can optionally estimate take-home using tax and other deductions (estimator only). For a more detailed take-home estimate use our salary tax estimator or the hourly pay calculator for weekly or monthly gross.

What is time and a half?

Time and a half means 1.5× your normal hourly rate. For example, if you earn $20/hour, overtime is $30/hour. So 10 overtime hours = $300 in overtime pay. Many jurisdictions require at least time-and-a-half for hours over a weekly threshold (often 40).

When does double time apply?

Double time (2× your rate) is sometimes required for holidays, Sundays, or hours beyond a second threshold (e.g. after 12 hours in a day). Rules vary by location and contract. Use our calculator to add double-time hours separately when your employer applies them.

How to calculate overtime manually (example)

Example: $25/hour, 40 regular hours, 8 overtime hours at 1.5×. Regular pay = 25 × 40 = $1,000. Overtime pay = 25 × 1.5 × 8 = $300. Total = $1,300. Use our hourly pay calculator for weekly or monthly income, or the salary to hourly calculator to convert salary to an hourly rate.
