Work Hours Calculator
Quickly calculate daily and weekly work hours from a single shift pattern with breaks.
Result
Enter your shift details.
Formula
Daily = (End − Start) − Break. Weekly = Daily × Days.
Example calculation
8:00-16:30 with 30 min break, 5 days = 8h × 5 = 40 hours/week.
Common mistakes
- Forgetting to multiply by days.
- Using minutes greater than 60.
About this calculator
What the Work Hours calculator does
Compute daily and weekly work hours from a single steady shift pattern with breaks. Enter one start time, one end time, the unpaid break minutes, and the number of days you work in a typical week, and the calculator returns daily and weekly totals in HH:MM and decimal form.
When to use it
Use it for a quick capacity check, a job offer comparison, or when planning a recurring schedule. It is helpful when you are estimating yearly hours from a steady shift, when you are negotiating hours during an interview, or when you want to model what dropping to a four day week would do to your weekly total.
How the calculation works
The calculator finds daily paid hours from start, end, and break, then multiplies by the number of days you work in a week. Daily paid time is end minus start minus break. Weekly time is the daily figure times the number of work days. Both are reported as HH:MM and as decimal hours.
How to read the result
The daily figure represents one shift, useful for confirming a schedule. The weekly figure is the daily value multiplied by your days. Decimal hours convert easily into pay, into annual hours (multiply by 52), or into a budgeted project capacity. Use whichever format your downstream tool expects.
Practical example
An 8:00 AM to 4:30 PM shift with a 30 minute break is 8.00 hours per day. Five days a week is 40.00 hours per week, or roughly 2,080 hours per year. Switching to four 10 hour days keeps weekly hours the same at 40 but changes the daily figure to 10. A 9 to 3 part-time shift with no break is 6 hours daily, 30 weekly.
Common limitation or caution
Real schedules vary week to week. This is a steady-state estimate, not a predictor of overtime, holidays, paid time off, or unpaid leave. If your week regularly varies, use the Weekly Timesheet Calculator instead so you can enter each day separately and capture the differences.

Before you use the result
Our calculators give quick payroll-time and pay estimates. Your final paycheck depends on factors this tool does not see, including employer policy, state and local rules, time clock rounding, paid versus unpaid breaks, premium pay, deductions, and how your payroll provider applies them.
- Confirm pay rules with your employer, payroll provider, or HR team.
- Overtime, breaks, and rounding rules can change by state.
