How to Calculate Weekly Work Hours
Using an accurate weekly hours calculator makes tracking your weekly work schedule simple. Whether you are filling out timesheets, reviewing a pay stub, or managing employee shifts, this weekly working hours calculator computes daily totals and deducts unpaid meal breaks automatically.
To calculate weekly work hours step-by-step:
- Check each day you worked (Monday through Sunday).
- Enter your daily start time and end time for each shift.
- Deduct unpaid lunch periods or break times in minutes.
- Combine daily net hours to calculate your total weekly hours worked.
Weekly Hours Calculator Schedule Examples
Here is how common shift routines look when calculated with a week hours calculator:
- Standard Full-Time: 8 hours/day × 5 days = 40 hours per week
- Shift with 1-Hour Lunch: 9:00 AM – 5:00 PM with 60 min break = 7 hours/day (35 hours/week)
- Part-Time Schedule: 6 hours/day × 4 days = 24 hours per week
- Decimal Time for Payroll: 37 hours 30 minutes = 37.5 decimal hours
Common Weekly Work Schedules Reference
Weekly schedules vary by company, industry, and position. Use this reference to verify your weekly hours worked against common schedule classifications:
| Weekly Hours | Typical Daily Schedule | Days Worked | Schedule Type |
|---|---|---|---|
| 20 Hours | 4 hours / day | 5 days | Part-Time |
| 30 Hours | 6 hours / day | 5 days | Part-Time |

Calculating Weekly Working Hours With Breaks
Unpaid meal and lunch breaks reduce your total billable time. For example, being at work from 8:00 AM to 5:00 PM with an unpaid 1-hour lunch break equals 8 net hours per day rather than 9. Over a five-day work week, your weekly hours worked equal 40 hours. For detailed daily calculations, pair this tool with our Work Hours with Lunch Calculator or Time Card Calculator.
Convert Weekly Hours to Decimal Time
Most payroll and billing software systems require decimal hours. Divide minutes by 60 to convert them:
- 15 minutes = 0.25 hours
- 30 minutes = 0.50 hours
- 45 minutes = 0.75 hours
An hours per week calculator performs these conversions automatically so your timesheet entries remain error-free.
