What is a weekly hours calculator?
A weekly hours calculator adds up time worked across a full week. It is useful for timesheets, payroll, freelancers, contractors, shift workers and employees tracking regular and overtime hours.
How to calculate weekly hours worked
Calculate the net hours for each work day, subtract breaks, then add the daily totals together. The weekly total can be shown as hours and minutes or as decimal hours for payroll.
How to subtract lunch and breaks
Breaks are subtracted from the raw shift duration for each day. For example, 09:00 to 17:00 is 8 hours, but with a 30-minute lunch break the paid time is 7 hours 30 minutes.
How to calculate overtime hours
Overtime is the time worked above your chosen weekly threshold. If the threshold is 40 hours and you work 42 hours 30 minutes, your overtime is 2 hours 30 minutes.
How to convert weekly hours to decimal hours
Divide minutes by 60 and add them to the whole hours. For example, 37 hours 30 minutes = 37.50 hours, 40 hours 15 minutes = 40.25 hours, 42 hours 30 minutes = 42.50 hours, 30 minutes = 0.50 hours, and 45 minutes = 0.75 hours.
How to estimate weekly pay
Multiply regular hours by the hourly rate, then multiply overtime hours by the hourly rate and overtime multiplier. Add both figures together to estimate total weekly pay.
How overnight shifts are handled
If an end time is earlier than the start time, the calculator treats the shift as crossing midnight and ending the next day. For example, 22:00 to 06:00 is 8 hours.
Time clock rounding explained
Time clock rounding adjusts start and end times to the nearest selected interval before daily hours are calculated. Common intervals are 5, 6, and 15 minutes.
