Free Time Card Calculator

What is a time card calculator?

A time card calculator is a free online tool that helps you instantly calculate time card calculator results without any signup or software installation. It runs entirely in your browser — no signup, no app, and no data is ever sent to a server.

If you clock in and out and need to know your total hours, overtime, and gross pay, this is the tool. Enter your start and end times for each day of the week with optional break deductions, and it calculates total regular hours, overtime, double time, and your weekly gross pay automatically. It handles daily and weekly overtime, night shift differentials, multiple breaks per day, both 12-hour and 24-hour clock formats, rounding options, and projects your annual pay — all while saving your data for next time. Beats doing the "8:53 to 5:17 minus 42 minutes for lunch" arithmetic on a napkin.

How it works

For each day, subtract the clock-in time from the clock-out time to get hours worked. Subtract any unpaid break time. Sum the daily totals to get your weekly total. Hours above 40 in the US are classified as overtime and paid at a minimum of 1.5x the regular rate under the Fair Labor Standards Act. The calculator offers two overtime rule options: weekly overtime (hours beyond 40 per week) which follows federal law, and daily overtime (hours beyond 8 per day) which matches requirements in states like California and Nevada. You can also customize the overtime multiplier — some union contracts or company policies use double time (2x) or time-and-a-half with different thresholds.

For overnight shifts (e.g., 11 PM to 7 AM), the calculator automatically adds 24 hours to the end time to correctly calculate 8 hours worked across midnight. Enter your hourly rate to instantly see gross regular pay and overtime pay calculated for you. The tool supports both 12-hour (AM/PM) and 24-hour time formats, with a toggle to switch between them. The rounding feature lets you round to the nearest minute, 15-minute increment (common in many workplaces), or 1/10th of an hour (6-minute increments used by many payroll systems). You can also display hours in decimal format (5.75 hours) instead of hours and minutes (5h 45m), which is useful when entering time into payroll software that expects decimal inputs.

When to use a time card calculator

Use a free time card calculator at the end of each work week to verify your paycheck matches the hours you actually worked. Hourly employees, freelancers, and part-time workers benefit most — especially those who work varying schedules or overtime hours. Tracking your own time independently of your employer's records helps catch discrepancies before payday, and having documented hours can be invaluable if a payroll dispute arises. The print function produces a clean time card report suitable for record-keeping or submitting with your timesheet.

Managers and small business owners can use it to quickly compute payroll hours without manual arithmetic or spreadsheet formulas. The break deduction fields (two per day) handle scenarios like unpaid lunch breaks plus a second break, common in longer shifts or split shifts. The Sunday-start option lets you align the work week to your company's schedule, which is especially useful for businesses that run Sunday-through-Saturday pay periods. All data is saved in your browser's local storage, so your time card entries persist even if you close the tab and come back later. Use the reset button when starting a new pay period, or keep multiple weeks running by noting down totals separately. For hourly workers, comparing your calculated gross pay against your pay stub is one of the best ways to ensure you are being compensated correctly for every hour worked.

Double time and night shift

Double time is typically paid at 2x the regular rate for hours worked beyond 12 in a single day, or on holidays. The calculator lets you set both the double-time threshold (default 12 hours) and the multiplier (default 2x). When any day exceeds the threshold, those hours are calculated at double time. Night shift differential adds a flat dollar amount per hour to all weekly hours when the night shift checkbox is selected. This is common in healthcare and manufacturing, where overnight workers receive $1–$5 per hour extra as a shift differential.

How to use this calculator

1. Enter your daily times — For each work day, enter your clock-in time and clock-out time. Skip days off by leaving them blank.
2. Add break time (optional) — Enter break minutes for each day to deduct unpaid break time from your daily total.
3. Enter your hourly rate — Type your hourly pay rate to see your gross regular pay, overtime pay, double-time pay, night shift differential, and total weekly pay.
