Add or subtract time intervals. Enter hours:minutes or use the time picker.
Enter your clock-in and clock-out times for each day of the week in the Time Card tab. Add break minutes if applicable and toggle off days you didn't work. The calculator automatically sums your total hours, detects overnight shifts, and applies FLSA overtime rules (over 40 hrs/week). Switch to the Pay Calculator tab to multiply your hours by your hourly rate and see gross pay.
Under federal FLSA rules, any hours over 40 in a workweek are paid at 1.5× your regular rate. California applies stricter daily overtime: 1.5× after 8 hours/day and 2× after 12 hours. Alaska and Nevada also have daily overtime rules. Use the Overtime tab to calculate for any state.
Enter your clock-in and clock-out times for each day of the week in the Time Card tab. Include your break time in minutes. The calculator subtracts breaks and sums up all your daily hours to give you a weekly total. It also handles overnight shifts (e.g., 10 PM to 6 AM).
Under the federal FLSA, any hours over 40 in a workweek must be paid at 1.5× your regular rate. Some states have stricter rules: California requires daily overtime after 8 hours, and double time after 12 hours or on the 7th consecutive day. Alaska and Nevada also have daily overtime rules.
Overtime pay = Overtime hours × (Regular hourly rate × OT multiplier). For example: 5 OT hours × ($18 × 1.5) = $135 in overtime pay, on top of your regular pay of 40 × $18 = $720, for a gross total of $855.
Gross pay is your total earnings before any deductions. Net pay (take-home pay) is what's left after taxes, Social Security, Medicare, health insurance, and other withholdings. The Pay Calculator estimates gross pay; your actual net pay will be lower based on your tax bracket and deductions.
In the Hours Calc tab, enter each time interval in hours and minutes (or use the H:MM format). You can add as many rows as needed. Choose whether to add them all together or subtract from the first entry. The result shows in your chosen format: hours & minutes, decimal hours, or total minutes.
Multiply the decimal part by 60. For example: 7.75 hours = 7 hours and (0.75 × 60) = 45 minutes = 7h 45m. Alternatively, 8.5 hours = 8h 30m. The Hours Calculator does this conversion automatically.
Yes! The Time Card Calculator automatically detects overnight shifts. If your time out is earlier than time in (e.g., in at 10:00 PM, out at 6:00 AM), it adds 24 hours to correctly calculate the 8-hour shift.
In the US, full-time is typically 35–40 hours per week, or 7–8 hours per day. Part-time is generally under 35 hours/week. The ACA (Affordable Care Act) defines full-time as 30+ hours/week for benefits purposes. Exact definitions vary by employer.
Under the federal FLSA, most employees are entitled to overtime at 1.5× their regular rate for hours over 40 per week. Exceptions include salaried "exempt" employees (executive, administrative, professional roles earning over $684/week), independent contractors, and certain farm workers. Check with your state labor board for state-specific rules.
Biweekly means paid every two weeks — 26 paychecks per year. Each check is your annual salary ÷ 26. Semimonthly means paid twice a month (e.g., 1st and 15th) — 24 paychecks per year. Each check is annual salary ÷ 24. Biweekly paychecks are slightly smaller but you get two "extra" paychecks per year in months with three pay dates.
Hourly employees are paid for each hour worked and are generally entitled to overtime under the FLSA. Salaried employees receive a fixed amount regardless of hours worked. Salaried employees classified as "exempt" are not entitled to overtime pay, though misclassification is a common labor violation employers should be aware of.
The federal minimum wage is $7.25/hour, but many states set higher rates. As of 2025: California $16.50, Washington $16.28, New York $16.00, Colorado $14.81, Florida $13.00. Several cities have even higher local minimums — Seattle, San Francisco, and NYC all exceed $17/hour. Always check your state and local rates.
A biweekly time card covers two consecutive work weeks — 14 days, typically 80 hours for full-time employees. To calculate biweekly hours, simply add your hours from both weeks together. Our calculator handles this automatically: enter your daily in/out times for each week and the total updates instantly.
For overtime purposes, FLSA calculates overtime per individual work week — not per pay period. So even if your total biweekly hours are 80, if you worked 45 hours in week 1 and 35 in week 2, you owe 5 hours of overtime pay for week 1 only.
| Pay Schedule | Pay Periods/Year | Typical Hours/Period | OT Calculated Per |
|---|---|---|---|
| Weekly | 52 | 40 hrs | Work week |
| Biweekly | 26 | 80 hrs | Each work week |
| Semi-monthly | 24 | ~86.7 hrs | Work week |
| Monthly | 12 | ~173.3 hrs | Work week |
An 8-hour shift is the standard US workday. With a 30-minute unpaid lunch break, your clock-in to clock-out span is 8.5 hours (e.g. 9:00 AM to 5:30 PM). With a 60-minute break it's 9 hours on the clock (8:00 AM to 5:00 PM). Our time card calculator subtracts your break minutes automatically so your recorded hours are always net of breaks.
| Shift Type | Time In | Time Out | Break | Net Hours |
|---|---|---|---|---|
| Day shift | 9:00 AM | 5:30 PM | 30 min | 8.0 hrs |
| Early shift | 6:00 AM | 2:30 PM | 30 min | 8.0 hrs |
| Evening shift | 2:00 PM | 10:30 PM | 30 min | 8.0 hrs |
| Night shift | 10:00 PM | 6:30 AM | 30 min | 8.0 hrs |
| 10-hr shift | 7:00 AM | 5:30 PM | 30 min | 10.0 hrs |
| 12-hr shift | 7:00 AM | 7:30 PM | 30 min | 12.0 hrs |
A punch card calculator (also called a time punch clock calculator) converts raw in/out timestamps into total hours worked. It works by subtracting the clock-in time from the clock-out time, then subtracting any break time. The result is your net worked hours for that shift.
Formula: Net Hours = (Time Out − Time In) − Break Minutes ÷ 60
Example: Clock in 8:15 AM, clock out 4:45 PM, 30-min break = (8.5 hours) − 0.5 = 8.0 net hours. Our calculator handles all time formats including overnight shifts — if your out time is earlier than your in time, it automatically adds 24 hours.
Use this table to quickly check how many hours per year different schedules produce, and what overtime looks like for each:
| Schedule | Hrs/Week | Hrs/Year | OT Hrs/Week | Status |
|---|---|---|---|---|
| Part-time | 20 | 1,040 | 0 | No OT |
| Part-time | 32 | 1,664 | 0 | No OT |
| Full-time | 40 | 2,080 | 0 | No OT |
| Full-time + OT | 45 | 2,340 | 5 hrs @ 1.5× | OT applies |
| Full-time + OT | 50 | 2,600 | 10 hrs @ 1.5× | OT applies |
| 4×10 schedule | 40 | 2,080 | 0 (federal) | No federal OT |
A timesheet calculator helps hourly workers and managers track hours worked across a pay period and calculate gross pay. Unlike salaried employees who receive a fixed paycheck, hourly employees are paid for exact hours worked — making accurate timekeeping essential for both payroll compliance and personal budgeting.
Key timesheet rules under US law:
Many employers — especially in healthcare, logistics, and government — use military time (24-hour clock) on timesheets to eliminate AM/PM confusion. Converting military time to standard time is simple: for any hour above 12, subtract 12 and add PM. For hours 1–11, add AM. Midnight is 0000, noon is 1200.
| Military Time | Standard Time | Military Time | Standard Time |
|---|---|---|---|
| 0000 | 12:00 AM (Midnight) | 1200 | 12:00 PM (Noon) |
| 0600 | 6:00 AM | 1300 | 1:00 PM |
| 0700 | 7:00 AM | 1430 | 2:30 PM |
| 0800 | 8:00 AM | 1500 | 3:00 PM |
| 0830 | 8:30 AM | 1600 | 4:00 PM |
| 0900 | 9:00 AM | 1700 | 5:00 PM |
| 1000 | 10:00 AM | 1800 | 6:00 PM |
| 1030 | 10:30 AM | 1900 | 7:00 PM |
| 1100 | 11:00 AM | 2300 | 11:00 PM |
To calculate hours worked in military time: subtract the start time from the end time. If you worked 0730–1600, that's 1600 − 0730 = 830, which equals 8 hours 30 minutes. For overnight shifts (e.g., 2200–0600), add 2400 to the end time: 0600 + 2400 = 2600, then 2600 − 2200 = 400 = 4 hours. Our time card calculator handles both standard and military time input automatically.
Decimal time is another format you'll see on payroll systems. To convert minutes to decimal: divide by 60. So 30 minutes = 0.50, 15 minutes = 0.25, 45 minutes = 0.75. A shift of 8 hours 45 minutes = 8.75 decimal hours. Multiply by your hourly rate to get gross pay.
Understanding your pay period matters for calculating how many paychecks you receive per year, how overtime is counted, and how to budget. Here's how the four main pay periods compare:
| Pay Period | Frequency | Paychecks/Year | OT Calculated | Common Industries |
|---|---|---|---|---|
| Weekly | Every 7 days | 52 | Per week | Construction, skilled trades |
| Biweekly | Every 14 days | 26 | Per week (not per period) | Most US employers |
| Semi-Monthly | Twice/month (1st & 15th) | 24 | Per work week | Office, corporate |
| Monthly | Once/month | 12 | Per work week | Some government, nonprofit |
Important: Under FLSA, overtime is always calculated per individual workweek (Sunday–Saturday or your employer's designated 7-day period), regardless of pay period. A biweekly employee who works 50 hours in week 1 and 30 in week 2 is owed 10 hours of overtime for week 1, even though the biweekly total is only 80 hours. You cannot "average" hours across a biweekly period to avoid paying overtime.
Biweekly vs semi-monthly: These sound similar but have a key difference. Biweekly pay periods are always exactly 14 days, so some months have 3 pay periods (3 paydays occur about twice per year). Semi-monthly pay is always on fixed calendar dates — typically the 1st and 15th — so each period varies between 13 and 16 days depending on the month. Biweekly is the most common pay schedule in the US, used by about 43% of employers.
Federal FLSA requires 1.5× overtime for hours over 40/week. But several states have stricter rules — daily overtime thresholds, higher multipliers, or mandatory rest periods. Here's what hourly workers need to know by state:
1.5× pay for all hours over 40 in a workweek. No daily overtime threshold. Examples: Texas, Florida, New York, Illinois, Pennsylvania, Georgia, Ohio, North Carolina, Michigan, Washington.
Some states have specific overtime exemptions that differ from federal law — for example, Colorado requires 1.5× for hours over 12/day and for the first 12 hours on a 7th consecutive day. Always verify with your state's Department of Labor. Our Overtime Calculator applies California, Alaska, and Nevada rules automatically when you select your state.
Once you know your gross pay from the time card calculator, your take-home pay (net pay) will be lower due to mandatory and voluntary deductions. Here's what you'll typically see on a US pay stub:
| Deduction | Rate / Amount | Who Pays | Notes |
|---|---|---|---|
| Federal Income Tax | 10–37% (varies) | Employee | Based on W-4 withholding |
| Social Security | 6.2% (up to $168,600 income) | Employee + Employer | FICA tax — both pay 6.2% |
| Medicare | 1.45% (+ 0.9% over $200k) | Employee + Employer | FICA tax — no income cap |
| State Income Tax | 0–13.3% | Employee | 9 states have none (TX, FL, etc.) |
| 401(k) / 403(b) | Up to $23,000/year (2024) | Employee (voluntary) | Pre-tax, reduces taxable income |
| Health Insurance | Varies by plan | Employee + Employer | Pre-tax if employer-sponsored |
For a quick estimate: most hourly workers in the $15–$25/hour range take home approximately 65–72% of their gross pay after all deductions. Use the Pay Calculator tab to estimate your net take-home based on your state and gross hours.
