Calculate billable hours and decimal time worked from shift start time, end time, and unpaid break deductions.
Enter start and end times to calculate total working hours for invoicing and timesheet purposes.
A working hours calculator finds the total hours between a start time and an end time. For multiple time entries, it adds them all up to give the total hours for a day or period.
This is the essential tool for any freelancer or hourly worker who needs to track and bill time.
Hourly invoices are based on hours worked. Without accurate time tracking, you either under-bill (losing income) or over-bill (damaging client trust).
A working hours calculator gives you an accurate total to put on your invoice.
Most hourly work excludes unpaid breaks. Enter start time, subtract break duration, and end time to get net billable hours.
Always clarify with clients whether break time is included or excluded in your hourly billing.
Employers use working hours to calculate employee wages. Enter the total hours worked and multiply by the hourly wage to get gross pay.
For payroll purposes, accurate time records protect both employer and employee.
After calculating total hours, use the hourly invoice calculator on Tez Invoice to multiply by your rate for the invoice total. Then use the free invoice generator to create the formal invoice.
The full workflow: track hours with this tool, calculate the total with the invoice calculator, create the invoice.
