Built differently
What this time card calculator does that others do not
Most free timesheet calculators still make you press a button to see a total, break on a phone screen, or hide the useful settings behind a sign-up form. This one is built around the awkward cases real timesheets actually contain.
Overnight and graveyard shifts
Clock in at 10:00 pm and out at 6:30 am and the calculator recognises the shift crossed midnight, counting 8.5 hours instead of returning a negative number or an error.
Daily overtime, not just weekly
Federal rules pay overtime past 40 hours a week, but several states pay it past 8 hours in a single day, with double time past 12. Switch rules and the split recalculates immediately.
Forgiving time entry
Type 9, 9:30, 930, 9.30, 9a, 5p or 17:30 — all of them parse correctly. You should not have to reformat your own handwriting to use a calculator.
Decimal hours for payroll
Payroll systems want 8.75, not 8:45. Every total is shown in both formats side by side, with optional rounding to the nearest 5, 6 or 15 minutes to match your employer's policy.
No account, no upload
There is no registration wall and no server round trip. The maths runs in your browser, which also means it keeps working on a patchy warehouse or site connection.
How it compares to typical free timesheet tools

How to use it
How to calculate your time card in five steps
The whole process takes under a minute once your times are in front of you.
- Set the week and your first day. Pick the date your pay week starts and whether your week runs Monday, Sunday or Saturday first. Each row is then labelled with a real date, which makes the printout easy to match against a paper card.
- Enter clock-in and clock-out times. Type them however you normally write them. If a shift runs past midnight, just enter the actual finish time — the calculator works out that the day rolled over.
- Subtract unpaid breaks. Put the unpaid minutes in the break column, usually 30 or 60 for lunch. Paid rest breaks should be left out, because those already count as time worked.
- Choose your overtime rule and rounding. Weekly over 40 hours matches the federal standard. Choose a daily rule if your state or contract pays overtime past 8 hours in a day, and set rounding to match your employer's policy.
- Add your hourly rate and export. Enter a rate to see estimated gross pay with overtime premiums applied, then copy the summary, download a CSV or print a clean timesheet for payroll.
Why it matters
Who benefits from an accurate weekly timesheet
Small, repeated rounding mistakes are the ones that quietly cost the most over a year.
Hourly employees
Checking your own hours before you submit them is the simplest way to catch a missed shift or a break that was deducted twice. Ten minutes lost each day is roughly 43 hours over a year — more than a full working week.
Freelancers and contractors
Billable time is easier to defend when it is broken down by day with breaks removed. Export the CSV and attach it to an invoice so a client can see exactly what they are paying for.
Shift and night workers
Rotating and overnight schedules are where manual maths goes wrong most often, because the shift crosses midnight and the day boundary moves. This calculator handles that case by default.
Managers and small business owners
Sanity-check a timesheet before it reaches payroll. Seeing the regular, overtime and double-time split separately makes an unexpectedly large payroll cost easy to explain.
Questions
Time card calculator FAQs
How do I calculate time card hours manually?
Convert both times to a 24-hour clock, subtract the start from the end, then subtract unpaid break minutes. For a 9:00 am to 5:30 pm shift with a 30-minute lunch, that is 17:30 minus 9:00, which gives 8 hours 30 minutes, less 30 minutes of break, leaving 8 hours exactly. Repeat for each day and add the daily totals together for the week. The calculator above does all of this for every row at once, which removes the two most common errors: forgetting to carry minutes past the hour, and subtracting the break from the wrong day.
Does this time card calculator subtract lunch breaks?
Yes. Each day has its own break field in minutes, so you can enter 30 for a half-hour lunch on one day and 60 on another. Only unpaid breaks should be entered. Short paid rest breaks, typically 10 to 20 minutes, normally count as hours worked and should not be deducted. The total time removed across the week is shown separately in the summary panel so you can confirm nothing was double-counted.
How is overtime calculated on a time card?
Under the federal Fair Labor Standards Act, non-exempt employees earn at least 1.5 times their regular rate for hours worked beyond 40 in a workweek, and only actual hours worked count toward that threshold — unpaid lunch does not. Some states add a daily rule, paying overtime past 8 hours in a single day and double time past 12, regardless of the weekly total. Select the rule that matches your situation and the calculator splits your hours into regular, overtime and double time accordingly. This tool gives an estimate; your employer's written policy or union agreement is the authority on your actual pay.
Can it handle overnight shifts that cross midnight?
Yes. When the finish time is earlier than the start time, the calculator assumes the shift ran into the next day and adds 24 hours before subtracting. A 10:00 pm to 6:30 am shift is therefore counted as 8 hours 30 minutes. The hours are credited to the day the shift started, which is how most weekly payroll periods treat a night shift. A night-shift marker appears on the row so you can see the rollover was detected.
How do I convert time card hours to decimal for payroll?
Divide the minutes by 60 and add them to the hours. Fifteen minutes is 0.25, 30 minutes is 0.5 and 45 minutes is 0.75, so 8 hours 45 minutes becomes 8.75. Payroll software almost always expects this decimal format, which is why entering 8.45 instead of 8.75 is such a common and expensive mistake. Every total on this page is displayed in both formats at once, so there is nothing to convert by hand.
What do the rounding options do?
They round each day's worked time to the nearest 5, 6 or 15 minutes before totalling. Six-minute rounding produces clean tenths of an hour and is common in professional billing, while quarter-hour rounding is widespread in payroll. Rounding must be applied neutrally rather than always in the employer's favour, so choose the increment your workplace actually uses. Leave it on exact minutes if you want the raw figure.
Is my timesheet data saved or sent anywhere?
No. Every calculation happens in your browser using a small amount of JavaScript, and nothing is transmitted to a server or stored in an account. There is no login and no email required to use any feature, including CSV export. Closing the tab clears your entries, and the Reset button clears them immediately.
Get your hours right before you submit them
A timesheet that is wrong by ten minutes a day is worth more than a week's wages over a year. Add up your week properly, see exactly where overtime starts, and hand payroll a figure you can stand behind.
