What this calculator does
A time card calculator turns clock-in and clock-out times into payable hours for a single day. Enter up to three in/out pairs — enough for a split shift with a lunch break punched out and back in — subtract any unpaid break, apply your employer's rounding rule, and you get both decimal hours (what payroll wants) and hours and minutes (what you actually worked).
Times can be typed almost any way: 9, 9:00, 900, 0900, 9am, 9 a.m., 17:30, 530p. They are tidied to HH:MM when you move to the next field, and anything unrecognisable turns red rather than quietly counting as zero.
Reading the numbers
| Figure | What it means |
|---|
| Paid hours | Time worked, after rounding and after the unpaid break comes off. This is the number that goes on a timesheet. |
| Hours & minutes | The same amount written the human way — 7h 30m rather than 7.50. |
| Regular | Paid hours up to your daily overtime threshold. |
| Overtime | Paid hours above the threshold, priced at the multiplier you set. |
| Gross pay | Regular hours × rate, plus overtime hours × rate × multiplier. Before any tax or deduction. |
Overnight and split shifts
If a clock-out time is earlier than its clock-in, the shift is assumed to run past midnight. 22:00 → 06:00 therefore counts as eight hours, not minus sixteen. The whole shift is credited to the day it started on, which is how most employers record night shifts.
For a split shift — say 06:00–10:00 and then 16:00–20:00 — use two of the shift rows. Time between the pairs is simply not counted, so you do not also need a break deduction for the gap.
Why rounding matters
Many employers do not pay to the minute. Common rules are rounding each punch to the nearest quarter hour (the "7-minute rule"), or rounding the day's total to the nearest tenth of an hour (6 minutes). Over a year those minutes add up in one direction or the other, which is why the rounding control is here rather than hidden.
In the United States, the FLSA permits rounding only where it is neutral over time — an employer may not consistently round in its own favour. If your paid hours are always lower than your punches suggest, that is worth raising.
Doing a whole week
This page deliberately handles one day. For a full week — with saved entries, weekly overtime, CSV export and a printable sheet — use the weekly timesheet calculator. Nothing you type there leaves your browser either.
Frequently asked questions
How do I calculate hours worked from clock-in and clock-out times?
Convert both times to minutes past midnight, subtract the start from the end, add 1,440 minutes if the result is negative (an overnight shift), then subtract any unpaid break. Divide by 60 for decimal hours. This calculator does all of that as you type.
How do I convert 7 hours 45 minutes to decimal?
Divide the minutes by 60 and add them to the hours: 45 ÷ 60 = 0.75, so 7h 45m is 7.75 hours. The minutes to decimal chart lists every value from 0 to 59.
Does the calculator subtract my lunch break automatically?
It subtracts whatever you enter in the unpaid break field — 30 minutes by default. If you clock out and back in for lunch instead, leave the break at 0 and use two shift rows; the gap between them is already excluded.
Can it handle a shift that ends after midnight?
Yes. When the clock-out is earlier than the clock-in, the shift is treated as crossing midnight, so 22:00 to 06:00 is eight hours.
Is my data saved anywhere?
No. This page keeps nothing — refreshing it clears the fields. Only the weekly timesheet saves entries, and it saves them in your own browser, never on a server.
Is the pay figure my take-home pay?
No, it is gross pay. Income tax, national insurance or FICA, pension or superannuation contributions and any other deductions all come off afterwards.
