How do I add up hours and minutes?

Add all the minutes together and all the hours together, then carry any minutes over 59 into hours. For example, 2 hours 45 minutes plus 1 hour 30 minutes is 3 hours and 75 minutes, which becomes 4 hours and 15 minutes. This calculator does the carrying for you.

How do I convert hours and minutes to decimal hours?

Divide the minutes by 60 and add to the hours. So 4 hours and 15 minutes is 4 plus 15 divided by 60, which is 4.25 decimal hours. Payroll uses decimal hours because they multiply cleanly by an hourly rate.

Can I work out my pay from hours?

Yes. Enter an hourly rate and the calculator multiplies your total decimal hours by that rate. The figure is gross pay, before PAYE tax and other deductions. For take-home pay, use our PAYE Calculator.

Add up hours and minutes quickly.

How to add up hours and minutes

Add all the minutes together first. Every 60 minutes becomes one hour, so carry those into the hours column, then add the hours. For example, three shifts of 2 hours 45 minutes, 3 hours 20 minutes, and 1 hour 30 minutes total 6 hours and 95 minutes, which tidies up to 7 hours and 35 minutes.

Worked example

You log 7 h 30 m on Monday, 6 h 45 m on Tuesday, and 8 h 15 m on Wednesday. The total is 22 hours and 30 minutes, which is 22.5 decimal hours.

At $28 an hour, that is 22.5 times $28, which is $630 gross for those three days.

Why decimal hours?

Payroll multiplies hours by a rate, and that is easier in decimal form. 30 minutes is 0.5 hours, 15 minutes is 0.25, and 45 minutes is 0.75. The calculator shows decimal hours so you can check pay at a glance.
