A free time card calculator for weekly, biweekly, semi-monthly and monthly pay periods. Handles lunch breaks, overtime, rounding, overnight shifts and decimal hours, then lets you print, download or share the result without an account.
Short answer: enter clock-in and clock-out for each day, subtract the unpaid lunch, and the calculator adds up paid hours as h:mm and decimal (9:00 AM to 5:30 PM with a 30 minute lunch is 8:00, or 8.00). Overtime is checked per workweek, and everything runs in your browser.
Type times like 9, 930, 9:30a, 17:30 or a whole range 9-5:30 in the first box.

One row per day starting on the first day. Separate times with tabs or commas: clock-in, clock-out, then more pairs for split shifts or lunch. A leading date or name column is ignored. You can also paste straight into a clock-in box.
PTO and holiday hours are paid at your hourly rate and are not counted toward overtime.

Everything stays in your browser. Your time card autosaves on this device only, and the share link carries the data inside the link itself.
Time on the clock minus unpaid lunch is what you get paid for. A 9:00 AM to 5:30 PM day is 8 hours 30 minutes on the clock, and with a 30 minute lunch deducted it is 8:00 (8.00 decimal). The same maths drives the 30 minute lunch break calculator, the 45 minute and the 60 minute versions. Pick one below and it applies to the whole period. For a single shift rather than a full card, the hour calculator is quicker.
If your employer deducts lunch automatically on long shifts, open Breaks, overtime and rounding and turn on auto-deduct, for example 30 minutes when the shift is over 6 hours. A break you type on a specific day always wins over the automatic one. Paid breaks can be switched on so nothing is deducted.
Enter when you start, how many paid hours you need and your unpaid lunch.
Clock out at
5:30 PM (17:30)
9:00 AM + 8 h + 30 min lunch = 5:30 PM
The biweekly mode shows 14 days at once, split into two workweeks with a subtotal for each. That matches how most US employers pay: two weeks of punches, one paycheck. Overtime is checked per workweek, so 45 hours in week one and 35 in week two gives 5 overtime hours, not zero. Semi-monthly mode covers the 1st to the 15th and the 16th to month end, and monthly mode covers the full calendar month.
The workweek start day matters for overtime. Many companies use Sunday or Monday; pick yours under Workweek starts on. In semi-monthly and monthly periods a workweek can start before the period does, and hours from outside the period are not included, so check the first and last week if your payroll uses a different cutoff.
Turn on the federal rule (over 40 hours in a workweek at 1.5x), the California rule set (daily over 8 at 1.5x, daily over 12 at 2x, seventh consecutive day) or build your own with weekly, daily and double-time thresholds and any multipliers. Overtime hours are placed on the days they actually happen, so the per-day pay is right and you can see exactly which day crossed the line.

Need a deeper look? The overtime calculator uses the same engine with more explanation. Overtime law differs by state, employer agreement and job type, so treat results as an estimate and confirm with your payroll team.
Payroll systems usually want decimal hours: 7:45 becomes 7.75. Every result here is shown both ways, and the Show hours as toggle decides which is large. To do it by hand, divide the minutes by 60. Common values: 15 minutes is 0.25, 30 is 0.50, 45 is 0.75, 20 is 0.33.

Switch the clock to 24h and the whole card uses military time: 0900, 1730, 2200. You can type with or without the colon, and the calculator still accepts a, p, am and pm if you prefer. Hours after 12:59 PM are the standard hour plus 12.
Many employers round punches. The 7-minute rule rounds to the nearest 15 minutes: a clock-in at 8:53 counts as 9:00, and 9:07 also counts as 9:00, while 9:08 counts as 9:15. Choose exact, 5, 6, 10 or 15 minutes. The Rounding impact panel shows the cost or gain compared with exact time so you can see whether a rule is neutral over a period.
| Minutes past the quarter | Counted as |
|---|---|
| 0 to 7 minutes | Rounded down |
| 8 to 14 minutes | Rounded up to the next quarter hour |

Monday to Friday, 9:00 AM to 5:30 PM, 30 minute unpaid lunch, $20 per hour.
Each day: 8:30 on the clock minus 0:30 lunch = 8:00. Five days is 40:00, exactly at the overtime line.
Monday to Thursday 8:00 AM to 6:30 PM, Friday 8:00 AM to 4:30 PM, 30 minute lunch, $20 per hour, federal 40 hour rule.
Four 10 hour days plus an 8 hour Friday is 48 hours. The 8 hours past 40 are paid at 1.5x, and they land on Friday in the grid.
Monday to Thursday 10:00 PM to 6:30 AM, 30 minute break, $22 per hour.
10:00 PM to 6:30 AM crosses midnight, so each shift shows an ends next day badge and 8:00 paid after the break, credited to the day it started.
Five days of punches like 8:53 AM and 5:08 PM, 30 minute lunch, $20 per hour, 7-minute rule.
Rounded to quarter hours the week comes to 38:30 instead of 38:25. Mixed early and late punches tend to cancel out.
A time card records punches for payroll. A timesheet records hours, often by project or client, for billing. The totals maths is the same, so this calculator works as a timesheet calculator and a time clock calculator too.
Typing times works well for a pay period. If you bill by project or want a record you did not have to remember, most time trackers are subscription tools where you start and stop timers. ScreenTimerAI works differently: it logs which apps and tabs you use on your own computer, keeps that data on your device and is a one-time purchase. See pricing.
Subtract clock-in from clock-out, then subtract the unpaid lunch. A 9:00 AM to 5:30 PM shift is 8 hours 30 minutes on the clock; minus a 30 minute unpaid lunch it is 8:00, or 8.00 in decimal. In the calculator, use the 30, 45 or 60 minute lunch buttons to apply the break to every day, type a different number of minutes on a single day, or switch to lunch punches and enter when you clocked out and back in. Under federal rules a bona fide meal period of 30 minutes or more where you are fully relieved of duty is unpaid, while short rest breaks of about 5 to 20 minutes are paid (29 CFR 785.18 and 785.19). Some states add their own meal break rules.
Set Pay period to Biweekly. The grid shows 14 days in two workweeks, starting on the weekday you pick under Workweek starts on. Pick any date in the first week and the calculator snaps to the correct start. Overtime is figured per workweek, not across the whole 14 days, because the federal Fair Labor Standards Act counts each fixed 7-day workweek on its own (hospitals and care facilities with an 8 and 80 arrangement are the exception). You get week subtotals plus the period total. Semi-monthly periods (1st to 15th, 16th to month end) and monthly periods work the same way.
Divide the minutes by 60 and add the whole hours. 7 hours 45 minutes is 7 + 45/60 = 7.75. 6 hours 20 minutes is 6.33. The calculator shows h:mm and decimal side by side for every day and for the totals, and the Show hours as toggle chooses which one is the large number. The table further down this page lists every minute from 0 to 59 with its decimal value, so you can check a single entry quickly.
Yes. If clock-out is earlier than clock-in, the calculator treats it as the next day and shows an ends next day badge, so 10:00 PM to 6:30 AM counts as 8:30 on the day the shift started. For a split shift use the split button to add as many in and out pairs as you need on the same day; the gaps between pairs are not counted. Typing a bare 6 after a 10 PM start is read as the next morning. Type 6p if you really mean the evening.
The federal rule pays 1.5 times the regular rate for hours over 40 in a workweek. California adds daily rules: hours over 8 in a day are paid at 1.5x, hours over 12 in a day at 2x, and on the seventh consecutive day of a workweek the first 8 hours are 1.5x and anything beyond is 2x. Daily overtime hours are not counted again toward the weekly 40. A few other states, such as Alaska, Colorado and Nevada, have their own daily rules for some employees. Use the Custom preset to set weekly, daily and double-time thresholds and the multipliers. The gross pay figure is an estimate for planning, not payroll, so check your state rules and employer policy.
The 7-minute rule rounds each punch to the nearest quarter hour: 1 to 7 minutes past a quarter rounds down, 8 to 14 minutes rounds up. Federal regulations allow rounding to the nearest 5 minutes, tenth of an hour or quarter hour as long as it averages out so employees are paid for all time worked (29 CFR 785.48). Pick a rounding rule under Breaks, overtime and rounding and the Rounding impact panel shows exactly how many minutes and dollars it adds or removes compared with exact time over the whole period.
Military time is the 24-hour clock. From 1:00 AM to 12:59 PM it looks the same as normal time, apart from a leading zero (0900 is 9:00 AM). From 1:00 PM subtract 12: 1730 is 5:30 PM, 2200 is 10:00 PM. 0000 is midnight and 1200 is noon. Switch the Clock toggle to 24h (military) and every time on the card converts instantly; you can type 1730, 17:30 or 17.30 in either mode.
A time card records clock-in and clock-out punches, usually for payroll, so it answers when you started and stopped. A timesheet records hours by day, and often by project, task or client, usually for billing or reporting. For adding up hours and overtime the math is identical, which is why this one calculator covers both a time card calculator and a timesheet calculator search.
Nothing you type is sent to a server. The calculator runs entirely in your browser and autosaves on your device using local storage. Printing or saving as PDF, CSV download, copy as table for Excel or Google Sheets, a JSON backup and a share link are all free and need no account. The share link stores the whole time card inside the link itself, so anyone with the link can open your card, so only share it with people you trust.
