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.

Hours Calculator

This calculator adds up multiple blocks of hours and minutes into a single total, so you can see exactly how much time you have logged without doing the carrying yourself. Enter the hours and minutes for each block, such as the hours worked on different days or across separate tasks, and add more rows if you need them. It returns your total in hours and minutes, the same total again as minutes, and the total as decimal hours, which is the format payroll systems use because it multiplies cleanly against an hourly rate. Add an hourly rate and it also shows the gross pay for those hours, working out decimal hours times the rate. This makes it useful for tallying a timesheet, checking hours across a working week, adding up shifts before submitting them for pay, or converting a mix of hours and minutes into one clean decimal figure for invoicing or reporting. It saves you manually carrying minutes over 60 into hours, which is where hand calculations most often go wrong. The gross pay figure is calculated before PAYE tax, ACC levies and KiwiSaver deductions are taken out, so treat it as an indicative before-tax figure rather than your take-home pay, and use our PAYE Calculator if you need the after-tax amount.

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.

Frequently asked questions

How do I convert minutes to decimal hours?

Divide the minutes by 60. So 45 minutes is 0.75 hours and 20 minutes is about 0.33 hours.

Is the pay figure my take-home pay?

No, it is gross pay before tax. For take-home pay after PAYE, ACC, and KiwiSaver, use our PAYE Calculator.
