How the time card calculator works
- Type the week’s times — time in, time out and the lunch break in minutes for each day. The daily hours appear in hours-and-minutes and decimal as you type.
- Pick weekly or biweekly, and the employee name and period dates for the card.
- Print the time card — one true-size page with the totals both ways and signature lines for employee and supervisor.
The math is deliberately boring and completely visible: the break comes off the day’s shift, a time out before time in is read as an overnight shift that ends the next day, and the period total is shown in both formats every time — 33 h 45 min is the same work as 33.75 decimal hours, and the card says so instead of making you translate.
Who prints time cards?
| You are | What the card does for you |
|---|---|
| An hourly worker checking your paycheck | Recompute your own hours from your times, both formats, before you query payroll |
| A small-shop manager | A week of cards that employees sign and you file — no spreadsheet needed |
Every calculator on a results page stops at the on-screen number, or hands you a spreadsheet template. The paper time card that payroll actually files — ruled, totaled, signed by both of you — is what this page prints.
The two formats, and why the card shows both
Paychecks and payroll systems usually want decimal hours; people read their day in hours and minutes. One number mis-read as the other is the classic timesheet mistake: 7:30 typed as 7.30 is seven minutes short. The card never makes you choose:
| Day’s work | Hours : minutes | Decimal |
|---|---|---|
| 9:00 – 17:00, 30 min lunch | 7:30 | 7.50 |
| 22:00 – 6:00 next day, 45 min lunch | 7:15 | 7.25 |
| 9:00 – 12:30, no break | 3:30 | 3.50 |
The optional pay rate line is plain arithmetic — hours times rate, before taxes and deductions — and the over-40 line says only what it knows: by how much the period exceeds 40 hours. Overtime rules depend on your employer and where you work; this tool makes no claim about them.
What the tool does not do
Holidays, overtime law, rounded quarter-hours, employer-specific rules — none of that is known here, and the card does not pretend otherwise. Each day holds one in/out pair and one break; split shifts need two rows or your own addition. And the honest note on limits that matter to everyone: check the printed card against what payroll actually pays before you sign it — that is the whole point of a signable card.
If your hours feed an invoice rather than a paycheck, the invoice generator takes it from here. And if this card is part of handing in notice, the two weeks notice letter maker computes your last working day and prints the letter — the two weeks notice guide walks the whole conversation, from what to say first to the finished letter.
Nothing you type leaves your device. The times are remembered only in this browser for your next visit, and clearing your browser data removes them.
Questions
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60. 7 hours 30 minutes is 7 + 30/60 = 7.50 decimal hours; 7 hours 15 is 7.25. The calculator shows both formats for every day and for the period total, so you can read your timesheet the way your paycheck and your payroll system each expect it.
How does the lunch break deduction work?
The break is subtracted from the day's shift before the hours are counted. A 9:00–17:00 shift with a 30-minute lunch is 7:30 (7.50 decimal), not 8:00. Leave the break at 0 for days you worked straight through.
What happens if my shift ends after midnight?
Type the times as they appear on the clock — 22:00 in, 06:00 out — and the calculator reads it as an overnight shift that ends the next day: 8 hours before the break. The day row and the printed card mark it with a star and a 'ends after midnight' note, so nobody has to guess.
Does it calculate overtime?
It does the arithmetic only: above 40 hours in the period, it says by how much — and that is all it says. Whether those hours are paid at an overtime rate depends on your employer, your contract and where you work, so the tool makes no payroll claim.
Can I use it for two weeks and a pay rate?
Yes. Switch the period to biweekly for a 14-day card, and type an hourly rate if you want the gross figure — the hours times the rate, plain arithmetic, before taxes and deductions.
What does the printed time card look like?
One page, true size (US Letter or A4): your name, the period, a row per day with in, out, break and hours in both formats, the totals, and two signature rules — yours and your supervisor's — with date lines. It prints from your device; nothing is uploaded.
Can one card hold two shifts in a day?
Not in this version — one in/out pair and one break per day. If you work split shifts, run each half on its own day row of a biweekly card, or add the two halves yourself and check the total.
