Time Card Calculator
Track weekly work hours with a free time card calculator. Enter clock-in and clock-out times, set breaks, and get regular hours, overtime, and gross pay.
About This Calculator
The Time Card Calculator helps employees, freelancers, and managers track weekly work hours and compute payroll estimates. Enter clock-in and clock-out times for each weekday from Monday to Friday, specify your unpaid break duration, and optionally add an hourly pay rate to see gross pay including overtime. This tool is ideal for timesheet preparation, shift planning, payroll verification, and freelance billing.
For each day, the calculator computes hours worked by subtracting the start time from the end time, then deducting the break duration. If an end time is earlier than the start time, the calculator automatically detects an overnight shift and adjusts the total by adding 24 hours. Daily hours are summed to get total weekly hours. If total hours exceed the overtime threshold (default 40 hours per week), the excess is classified as overtime. Regular hours are paid at the standard hourly rate, while overtime hours are paid at the specified multiplier (default 1.5x).
The formula for each day is: hours = (end time - start time in minutes - break minutes) / 60. If end time is before start time, 24 hours (1440 minutes) are added to the end time before subtraction. Weekly totals: regular hours = min(total hours, threshold), overtime hours = max(0, total hours - threshold), gross pay = (regular hours × rate) + (overtime hours × rate × overtime multiplier). All times use 24-hour HH:MM format for accuracy and clarity.
Regional Notes
India (IN): Under the Factories Act 1948, overtime is payable at double the ordinary rate of wages for work beyond 9 hours per day or 48 hours per week. Use the calculator with a 48-hour threshold and 2.0x multiplier to comply. Many Indian companies use a 9-hour workday including a 1-hour lunch break. The standard hourly rate varies widely by industry, from minimum wage (approximately ₹200-500/hour for skilled labor) to executive-level compensation.
United States (US): The Fair Labor Standards Act (FLSA) mandates overtime at 1.5x the regular pay rate for hours worked over 40 per week. Exempt employees may not qualify for overtime based on salary threshold and job duties. Many US employers use bi-weekly or semi-monthly pay periods; this calculator computes weekly hours that can be aggregated across your pay period. Federal minimum wage is $7.25/hour, though many states have higher minimums.
United Kingdom (UK): The Working Time Regulations 1998 establish an average 48-hour working week, though individuals can opt out. Overtime rates are typically negotiated in employment contracts — common rates include 1.5x for weekdays and 2x for Sundays or bank holidays. The National Living Wage for workers aged 23+ is £11.44/hour (2024-25 rate). Use the customizable overtime threshold and multiplier to match your specific contract terms.
Frequently Asked Questions
How does the Time Card Calculator work?
Enter your clock-in and clock-out times for each workday Monday through Friday, along with your unpaid break duration. The calculator computes hours worked per day, totals your weekly hours, separates regular hours from overtime beyond your set threshold, and calculates your gross pay including overtime pay at the specified multiplier.
Is the Time Card Calculator free?
Yes, all calculators on Calculy are completely free to use with no registration, downloads, or hidden charges.
How is overtime calculated?
Overtime is calculated as any hours worked beyond your weekly overtime threshold (default 40 hours). Regular hours are paid at your standard hourly rate, while overtime hours are paid at the overtime multiplier (default 1.5x, or time-and-a-half). You can adjust both the threshold and the multiplier to match your jurisdiction's labor laws.
What happens if my shift crosses midnight?
The calculator handles overnight shifts automatically. If your end time is earlier than your start time, the calculator assumes the shift crosses midnight and adjusts accordingly. For example, a shift from 10:00 PM to 6:00 AM is correctly calculated as an 8-hour shift minus your break.
Does the calculator include weekends?
The current version covers Monday through Friday. If you work weekends, enter those hours by adjusting your Friday or weekday times. The calculator supports any work schedule as long as start and end times are entered for the relevant days.
Can I use this for payroll purposes?
Yes, the Time Card Calculator provides accurate hour and pay calculations suitable for payroll estimation. Enter each day's actual clock-in and clock-out times, your break duration, hourly rate, and overtime settings to get a detailed breakdown of regular hours, overtime hours, and total gross pay. Always verify with your employer's official payroll system for compliance.
How do I calculate hours without a lunch break?
Set the Break Duration to 0 minutes if you do not take an unpaid break. The calculator will then compute your total hours as the direct difference between clock-out and clock-in times for each day.
What is the standard overtime threshold in different countries?
In the United States, the FLSA standard overtime threshold is 40 hours per week at 1.5x pay. In India, overtime is typically calculated after 9 hours per day or 48 hours per week at 2x pay under the Factories Act. In the UK, the Working Time Regulations recommend an average 48-hour week, though overtime rates vary by employment contract. You can customize both the threshold and multiplier in the calculator to match any jurisdiction.
