Weekly Hours Calculator
Calculate your total work hours from Monday to Sunday, including daily unpaid breaks, overnight shifts and your weekly target hours.
What Is a Weekly Hours Calculator?
A Weekly Hours Calculator helps you calculate your total work hours across an entire week.
You can enter your working times for Monday through Sunday, subtract unpaid breaks and see your total weekly hours in both hours-and-minutes and decimal format.
The ShiftCalco Weekly Hours Calculator is useful for employees, shift workers and anyone who needs to track working time across multiple days.
You can also set a weekly hours target to see whether your calculated total is below, exactly at or above that target.
How to Use the Weekly Hours Calculator
Enter your working schedule for each day of the week:
- Enter your weekly target hours.
- Enter your clock-in time for each working day.
- Enter your clock-out time.
- Enter any unpaid break taken during that day.
- Select Off for days you did not work.
- Repeat the process for Monday through Sunday.
- Click Calculate Weekly Hours.
The calculator will show your total weekly hours, total unpaid breaks, days worked, average hours per workday and progress toward your weekly target.
Weekly Hours Calculation Example
Suppose you work Monday through Friday from 9:00 AM to 5:00 PM with a 30-minute unpaid break each day.
Each shift is 8 hours long before the break is deducted.
After subtracting the unpaid break:
8 hours − 30 minutes = 7 hours 30 minutes per day
Over five working days:
7 hours 30 minutes × 5 = 37 hours 30 minutes
Your weekly total is therefore:
37 hours 30 minutes, or 37.50 decimal hours
How Are Weekly Work Hours Calculated?
The calculator works out the duration of each active working day separately.
For each day:
Clock-Out Time − Clock-In Time = Daily Shift Duration
If you enter an unpaid break:
Daily Shift Duration − Unpaid Break = Daily Work Hours
The calculator then adds the calculated hours from all active workdays:
Daily Work Hours Added Together = Total Weekly Hours
How Do Unpaid Breaks Affect Weekly Hours?
Unpaid breaks reduce the amount of time included in your calculated weekly work total.
For example, if you enter five 8-hour shifts with a 30-minute unpaid break each day:
- Total time before breaks: 40 hours
- Total unpaid breaks: 2 hours 30 minutes
- Total weekly hours: 37 hours 30 minutes
If you need to calculate the duration or return time of an individual break, use the Break Time Calculator .
What Are Decimal Weekly Hours?
Decimal hours represent your working time as a decimal number rather than hours and minutes.
This format can be useful for timesheets, payroll calculations and other work-hour calculations.
| Weekly Time | Decimal Hours |
|---|---|
| 35 hours 15 minutes | 35.25 |
| 37 hours 30 minutes | 37.50 |
| 38 hours 45 minutes | 38.75 |
| 40 hours | 40.00 |
| 42 hours 30 minutes | 42.50 |
| 45 hours 15 minutes | 45.25 |
What Is a Weekly Hours Target?
A weekly hours target is a number of hours you choose to compare with your calculated weekly total.
For example, you may enter a target of 40 hours.
If your weekly total is 37 hours 30 minutes, the calculator will show:
2 hours 30 minutes remaining to reach your target
If your weekly total is 45 hours, it will show:
5 hours above your 40-hour target
The target is simply a comparison feature. It does not determine whether any hours qualify as overtime.
Weekly Target vs Overtime Hours
Being above your weekly target does not automatically mean those additional hours qualify as overtime.
Overtime eligibility and rates can depend on employment rules, contracts, employer policies and other factors that apply to your situation.
If you want to separate regular hours from overtime hours using a specific threshold and overtime rate, use the Overtime Calculator .
Can I Calculate Different Hours for Each Day?
Yes. Each day has its own clock-in time, clock-out time and unpaid break field, so your schedule does not need to be the same every day.
For example:
- Monday: 8:00 AM to 4:00 PM
- Tuesday: 10:00 AM to 6:00 PM
- Wednesday: Day Off
- Thursday: 2:00 PM to 10:00 PM
- Friday: 9:00 AM to 5:30 PM
- Saturday: 6:00 PM to 11:00 PM
- Sunday: Day Off
The calculator processes each working day individually and combines the results into one weekly total.
How Do I Enter a Day Off?
Select the Off option beside any day you did not work.
That day will be excluded from your weekly hours, break total and average workday calculation.
This makes the calculator suitable for five-day schedules, rotating schedules, part-time work and other working patterns.
Can I Calculate Overnight Shifts During the Week?
Yes. The Weekly Hours Calculator supports work periods that cross midnight.
If your clock-out time is earlier than your clock-in time, the calculator treats the clock-out time as occurring on the following day.
For example:
- Clock In: 10:00 PM
- Clock Out: 6:00 AM
- Shift Duration: 8 hours before unpaid breaks
For a detailed overnight calculation with multiple paid and unpaid breaks, use the Overnight Shift Calculator .
For a simpler individual night-shift calculation, use the Night Shift Calculator .
Weekly Hours Example With an Overnight Shift
Imagine you have already worked 37 hours 30 minutes from Monday through Friday.
You then work Saturday from 10:00 PM to 6:00 AM with a 30-minute unpaid break.
Saturday's calculated work time is:
8 hours − 30 minutes = 7 hours 30 minutes
Your new weekly total becomes:
37 hours 30 minutes + 7 hours 30 minutes = 45 hours
Compared with a 40-hour target, this is 5 hours above target.
This comparison does not by itself mean that the five additional hours qualify for overtime.
What Does Average Hours Per Workday Mean?
Average hours per workday shows how many hours you worked on average across the days marked as working days.
The formula is:
Total Weekly Hours ÷ Number of Days Worked = Average Hours Per Workday
For example, if you work 37.50 hours across 5 days:
37.50 ÷ 5 = 7.50 hours per workday
Weekly Hours for Part-Time and Shift Workers
The calculator can be used for both part-time and variable shift schedules.
You do not need to work every day or have the same shift length each day. Mark unused days as off and enter your actual working times for the days you worked.
This is useful for schedules that include a mixture of morning, evening, night or overnight shifts.
Weekly Hours vs Individual Shift Hours
The Weekly Hours Calculator is designed to combine working hours across multiple days into one weekly total.
If you only need to calculate the duration, break and paid hours for one individual shift, use the Shift Hours Calculator .
If you have multiple separate clock-in and clock-out periods within a workday, use the Work Hours Calculator .

About the Weekly Hours Calculation
ShiftCalco calculates weekly hours using the clock-in times, clock-out times, unpaid breaks, days off and weekly target you enter.
The results are intended as a convenient work-time estimate. Actual payroll hours may differ if an employer uses specific time-rounding, break, attendance or payroll rules.
The weekly target comparison does not determine overtime eligibility or entitlement. Use the employment and payroll rules that apply to your situation when making official calculations.
