Time Card Calculator

Enter clock-in and clock-out times for each day of the week. Automatically calculates daily hours, weekly totals, overtime, and estimated pay.

Quick Answer

A standard 9-to-5 workweek (5 days, 30-minute lunch) totals 37.50 hours. If your weekly total exceeds the overtime threshold (typically 40 hours), the extra hours are calculated at overtime rate (usually 1.5x your normal pay).

About This Tool

The Time Card Calculator is a digital weekly timesheet that calculates your work hours from clock-in and clock-out times. It handles break deductions, distinguishes between regular and overtime hours, and optionally estimates your gross pay. It is designed for hourly workers, freelancers, and small business owners who need a quick and accurate way to total their weekly hours.

How It Works

Enter your clock-in and clock-out times for each day of the week. Add your unpaid break time in minutes. The calculator computes net hours for each day and sums them into a weekly total. If the total exceeds the overtime threshold (default 40 hours), the excess is shown as overtime. Enter an hourly rate to see estimated gross pay with overtime premium applied.

Overtime Rules

The default overtime threshold is 40 hours per week, which aligns with the Fair Labor Standards Act (FLSA) in the United States. Non-exempt employees must receive at least 1.5 times their regular rate for hours exceeding 40 in a workweek. Some states and employment agreements have different rules. California, for example, requires overtime for any hours exceeding 8 in a single day. The overtime threshold and multiplier fields are adjustable so you can match your specific requirements.

Break Time Handling

Each day has its own break field. This is important because break schedules can vary by day. You might take a 60-minute lunch on days with long shifts and skip breaks on shorter days. Only enter unpaid break time. If your employer provides paid 15-minute rest breaks, those should not be deducted from your work hours. The break is subtracted from the raw clock-in to clock-out duration, and the result cannot go below zero.

Overnight and Swing Shifts

The calculator supports overnight shifts. If your clock-out time is earlier than your clock-in time (for example, 11 PM to 7 AM), it automatically adds 24 hours and calculates 8 hours. This makes it suitable for night shift workers, hospital staff, security guards, and anyone whose shift crosses midnight. Each day is calculated independently, so you can mix day shifts and night shifts in the same week.

Accuracy and Limitations

This tool uses simple time arithmetic without rounding rules. Many employers round time to the nearest 5, 6, or 15 minutes. If your employer uses rounding, your actual paycheck may differ slightly from this estimate. The pay calculation shows gross earnings before any deductions for taxes, insurance, retirement contributions, or other withholdings. Always compare with your official pay stub for the final verified amount.

Who Uses Time Card Calculators

Hourly employees use time cards to verify that their paycheck matches their actual hours worked. Small business owners use them to prepare payroll. Freelancers and contractors track billable hours for invoicing. Managers review time cards to monitor labor costs and scheduling efficiency. Even salaried employees sometimes track hours for project allocation or overtime eligibility. Having a simple, free calculator available avoids the need for expensive time tracking software when all you need is a weekly hour total.

Frequently Asked Questions

How is overtime calculated?
Overtime is calculated based on total weekly hours exceeding the threshold you set (default 40 hours). Any hours above the threshold are classified as overtime. The overtime pay rate is your hourly rate multiplied by the overtime multiplier (default 1.5x, also called time-and-a-half). Federal law in the US requires 1.5x for hours over 40 per week for non-exempt employees.
Does this track daily overtime?
This calculator uses weekly overtime, which is the most common method in the US under the Fair Labor Standards Act (FLSA). Some states like California also require daily overtime (over 8 hours in a day). If you need daily overtime tracking, check your daily hours individually. The daily breakdown shows each day's hours so you can identify days exceeding 8 hours.
How do overnight shifts work?
If your clock-out time is earlier than your clock-in time (e.g., clock in at 22:00, clock out at 06:00), the calculator assumes an overnight shift and adds 24 hours to the clock-out time. This correctly calculates 8 hours for the example. You can use this for any shift that crosses midnight.
What break time should I enter?
Enter the total unpaid break time in minutes for each day. Common values are 30 minutes (half-hour lunch) or 60 minutes (full hour lunch). If you have multiple unpaid breaks, add them together. For example, two 15-minute breaks plus a 30-minute lunch = 60 minutes total. Paid breaks should not be entered since they count as work time.
Can I use this for biweekly pay periods?
This calculator covers one week (7 days). For a biweekly period, run the calculation twice — once for each week — and add the totals. The overtime threshold applies per week, not per pay period. So if you work 45 hours in week 1 and 35 hours in week 2, you have 5 hours of overtime from week 1 even though the biweekly total is 80 hours.
This calculator provides estimates only. Actual pay may differ due to employer rounding rules, tax withholdings, and deductions. Always verify with your official pay stub.
