About Timesheet Calculator

The Timesheet Calculator turns a week of clock-in and clock-out times into clean, ready-to-use totals without a spreadsheet or a single upload. You get one row for every day from Monday through Sunday, and each row takes three simple inputs: the time you started work, the time you finished, and how many minutes of unpaid break you took. As soon as you fill in a day, the tool works out that day's net hours and shows the result, rounded to two decimal places, right beside the row. Blank days are simply skipped, so you never have to zero anything out or delete rows you don't need.

The times use a standard 24-hour format, so 9 in the morning is 09:00 and 5 in the afternoon is 17:00. Behind the scenes the calculator converts each time to minutes, subtracts your unpaid break, and adds the day up. Overnight shifts are handled automatically: when your clock-out time is earlier than your clock-in time, the tool assumes you finished the next morning, while identical clock-in and clock-out times simply count as zero hours. A 22:00 start with a 06:00 finish therefore comes out as a full 8.00 hours rather than a negative number, which is exactly what shift workers, hospitality staff, nurses, security guards, and anyone on a night rotation need. If your break is longer than the shift itself, the day is clamped to zero instead of dipping below it.

Underneath the daily rows, a running weekly total keeps a live count of every hour worked across the seven days. If you want a pay estimate, add an hourly rate and pick a currency symbol; the calculator multiplies your total hours by your rate and shows the amount with proper thousands separators and two decimal places. Pay is entirely optional — leave the rate blank and the tool stays a pure hours calculator.

For people who want a quick overtime estimate, there is an optional rule you control yourself. You decide the weekly threshold in hours and the multiplier that applies above it, with a common starting point of 40 hours at 1.5 times pre-filled but switched off by default. When it is on, hours up to your threshold are paid at the base rate and the hours beyond it are paid at your chosen multiple. This is deliberately kept as simple convenience math and is not legal or payroll advice: overtime rules differ by country, state, and contract, so always confirm the numbers against the rules that apply where you work.

Everything runs locally in your browser using plain JavaScript. Your times, breaks, and pay figures are never sent to a server, never stored, and never shared, which makes the tool safe to use with real work data. It is ideal for freelancers reconciling billable hours, hourly employees checking a pay stub, small business owners preparing payroll, and managers double-checking a rota. Change any value and the totals update instantly, so you can experiment with different schedules, break lengths, and rates until the numbers match what you expect.

Frequently asked questions

How are overnight shifts calculated?
If your clock-out time is earlier than your clock-in time, the tool treats the shift as finishing the next day. For example, 22:00 to 06:00 is calculated as 8.00 hours instead of a negative value. Identical clock-in and clock-out times are counted as 0 hours.
Does the overtime option follow my local labor laws?
No. The overtime rule is a simple convenience calculation using a threshold and multiplier that you set yourself. It is not legal or payroll advice, and overtime rules vary by country, state, and contract, so always check the rules that apply where you work.
How are unpaid breaks handled?
Break minutes are subtracted from each day's gross hours before the total is calculated. If a break is longer than the shift, that day is counted as zero rather than a negative number.
Is my timesheet data uploaded or stored anywhere?
No. All calculations run locally in your browser with plain JavaScript. Your times, breaks, and pay figures are never sent to a server, saved, or shared.
