Why do timesheets use decimal hours instead of minutes?

Payroll systems multiply hours by an hourly rate using base-10 math. Multiplying 7.75 by a rate is direct, whereas 7:45 cannot be multiplied without converting first.

Can I calculate pay directly from decimal hours?

Yes, enter your optional hourly rate in the first part of the calculator and it will show the total amount based on your time.
