Overtime Calculator
Calculate overtime pay instantly. Choose a labour-law preset or use custom overtime thresholds and multipliers. If you do not know your total hours yet, add up your daily shifts first with our timesheet calculator.
The Overtime Formula
Overtime Hours = Total Hours Worked − Overtime Threshold
Overtime Pay = Overtime Hours × Hourly Rate × Overtime Multiplier
Example Calculation
If you work 45 hours in a week with a 40-hour threshold at $20/hour and a 1.5x multiplier: You have 5 overtime hours. Regular pay = 40 × $20 = $800. Overtime pay = 5 × $30 = $150. Total Pay = $950.
Overtime Inputs
Federal overtime in the USA generally starts after 40 hours/week at 1.5x.

How to Read an Overtime Estimate
An overtime estimate starts with the total number of hours worked in the selected period. The calculator compares that total with the threshold you choose, then separates regular hours from overtime hours. The overtime pay line uses the overtime multiplier, while regular pay uses the standard hourly rate.
The preset options are meant to make common scenarios faster, but overtime rules can depend on location, worker classification, industry, contract, collective agreement, and employer policy. A weekly rule, daily rule, holiday premium, weekend premium, or award-based rule can produce a different result. Use the custom option when your situation does not match a preset.
Before treating an overtime estimate as final, confirm that the total hours are net paid hours after unpaid breaks. Also confirm that the hourly rate is the regular rate required by the rule you are checking. Payroll systems may handle bonuses, commissions, shift differentials, and rounding in ways that require additional review.
Before You Use the Result
- Use one fixed workweek when checking weekly overtime.
- Do not average two separate weeks unless your rule specifically allows it.
- Check whether daily overtime, weekly overtime, or both apply.
- Keep a copy of the shifts that created the overtime total.
Calculator results are for planning and checking. For official payroll, tax, wage, overtime, or employment decisions, confirm the final answer with your employer, payroll provider, accountant, attorney, contract, union, or local labor authority.
Common Use Cases
- Paycheck verification: Checking that your employer paid the correct time-and-a-half premium for extra hours on your payroll.
- Manager scheduling: Estimating how much extra a weekend shift will cost before assigning it.
- Freelance billing: Adding a rush-fee premium to hours worked beyond a standard weekly limit.
Common Mistakes to Avoid
- Averaging weeks: In most places, you cannot average a 50-hour week and a 30-hour week to avoid overtime. Overtime is strictly week-by-week.
- Including unpaid breaks: Make sure you deduct your breaks using a timesheet calculator before counting total hours toward the overtime threshold.
- Mixing daily and weekly overtime: Some states (like California) have daily overtime, while federal law relies on a 40-hour weekly threshold. Select the correct preset for your area.
