      Formula

      Total minutes = sum of every entry converted to minutes
      Total = total minutes shown as hours:minutes
      Decimal hours = total minutes ÷ 60

      How to use it

      1. Type each duration, separated by commas.
      2. Read the total as hours:minutes and as decimal hours.
      3. Optionally enter an hourly rate to see the pay.

      Why you cannot just add the numbers

      Time is base 60, so 1:45 plus 1:30 is 3:15, not 2:75. The safe method is to convert everything to minutes, add, then divide by 60 for hours and keep the remainder as minutes — which is what this calculator does.

      Questions people ask

      How do I add hours and minutes?

      Add the minutes; for every 60, carry one hour. 2:45 + 1:30: 45 + 30 = 75 minutes = 1 hour 15, so the total is 4:15.

      What does a plain number mean?

      A number without a colon or unit is read as minutes, so 50 means 50 minutes. Write 2h or 2:00 for two hours.
