Work HoursCalculator
Turn clock-in and clock-out times into your daily work hours. Take off unpaid break durations, see the total in decimal hours, and get an estimate of the day's gross pay — without a spreadsheet.
Calculate Your Work Hours
Add your shift times and breaks to see your net working hours right away.
How the Work Hours Calculator Works
Four steps from clocking in to an estimate of what you earned.
Enter Shift Times
Set your clock-in and clock-out times, and tick overnight if the shift ends after midnight.
Add Break Time
Enter all unpaid break minutes — lunch, coffee and rest breaks. They come off your gross hours.
Set Pay Rate
Add your hourly rate and overtime threshold to get a pay estimate as well as hours.
Get Results
Read off your net hours, any overtime and your estimated pay, ready to check against a payslip.
What Is a Work Hours Calculator?
A purpose-built tool for employee time tracking and payroll checks.
Tracking work hours accurately
A Work Hours Calculator finds the net time worked in a shift. It starts with gross time — clock-out minus clock-in — and then removes unpaid break periods to leave the real working hours.
Decimal hours for payroll
Payroll systems run on decimal hours, so the conversion happens automatically: 7h 45m is shown as 7.75. Multiply that by the hourly rate and the day's pay is done.
Overtime tracking
Once net hours pass the overtime threshold — often 8 hours a day or 40 a week — the time is split into regular and overtime hours so each can be paid at the right rate.
Break deductions
Enter break time in minutes and it is taken off gross hours, leaving the net paid or billable hours. Lunch breaks of 30 to 60 minutes are the most common deduction.
Who Uses a Work Hours Calculator?
Useful for anyone who is paid, or bills, by the hour — a quick way to track time for pay.
Hourly Employees
Keep your own record of daily work hours and check that your payslip and your employer's time records agree.
Freelancers
Work out billable hours for each client session, convert to decimal and multiply by your freelance rate for the invoice.
HR & Payroll Teams
Check employee timesheets, confirm overtime and process payroll from reliable decimal-hour totals.
Healthcare Workers
Log 12-hour shifts, night rotations and on-call time, with overnight spans calculated for you.
Construction & Trades
Record daily site hours, allow for breaks and weather stoppages, and submit accurate time for project billing.
Retail Workers
Total up shift hours across changing rotas — mornings, evenings and split shifts with different breaks.
Tips for Accurate Work Hour Tracking
Simple habits that improve time management and keep payroll accurate.
Round to the nearest quarter hour
Many employers round punches to 15-minute steps — :00, :15, :30, :45. It keeps payroll processing simple while staying fair to both sides.
Track breaks separately
Note the break time taken as well as the break scheduled. A written record protects employee and employer alike if pay is ever disputed.
Use decimal hours for invoicing
Convert from HH:MM format to decimal before applying a rate: 7h 45m is 7.75 hours, and 7.75 × $30 = $232.50.
Document overtime daily
Record overtime per day (beyond 8 hours) as well as per week (beyond 40). Some jurisdictions require daily overtime pay even when the weekly total stays under 40.
Work Hours Calculator FAQ
Straight answers about the Work Hours Calculator.
Enter the time you clocked in, the time you clocked out and how many minutes of break you took. The calculator takes the breaks off the total and shows your net work hours both as HH:MM and as decimal hours.
Yes. Type the total unpaid break time in minutes — 30 for a lunch break, 45 for lunch plus a coffee break. It is subtracted from your gross hours, leaving the net working hours you are actually paid for.
Add your hourly rate in the pay-rate field. Your net decimal hours are multiplied by that rate to give an estimated gross pay before tax and deductions.
Yes. Switch on the overnight option when you clock out on the following day. A 10 PM to 6 AM shift is then counted as the 8 hours it really is.
Decimal hours show minutes as a fraction of an hour, so 7 hours 30 minutes is written 7.50. Payroll uses this format because it can be multiplied directly by a pay rate.
Yes. Set your overtime threshold — 8 hours a day by default — and any net hours above it are listed separately so you can apply the higher overtime rate.
Only unpaid breaks should be deducted. If your employer pays for short rest breaks, leave them out of the break field and enter just the unpaid time, such as an unpaid 30-minute lunch.
