How do I convert minutes to decimal hours?

Divide the minutes by 60. So 30 minutes is 0.50 hours, 15 minutes is 0.25, and 8 hours 30 minutes is 8.50 hours. Decimal hours are what most payroll and invoicing systems expect, because they multiply cleanly by an hourly rate. The calculator shows both the decimal figure and the hours-and-minutes version so you can use whichever you need.

How do I calculate hours for an overnight shift?

Just enter the times as normal — if the end time is on or before the start time, the calculator assumes the shift runs past midnight into the next day and adds 24 hours. So a shift from 22:00 to 06:00 correctly totals eight hours, and the dial shows the span wrapping through midnight. You do not need to split the shift into two parts.

How do I subtract a lunch or break?

Enter the break length in minutes and it is deducted from the clock span. For example, 09:00 to 17:30 is eight and a half hours on the clock; a 30-minute lunch leaves eight paid hours. If the break is longer than the shift, the result is simply zero rather than a negative number. In the weekly card, each day has its own break field.

How do I total my weekly hours?

Use the weekly time card: enter each day’s start, end and break, and the card adds them into a weekly total in both decimal hours and hours-and-minutes. It starts with a typical Monday-to-Friday, nine-to-five week with an hour for lunch (35 hours), which you can change to match your own shifts, including overnight ones. Add an hourly rate to see weekly pay.

How do I work out my pay from the hours?

Enter an hourly rate and the calculator multiplies it by your decimal hours to estimate gross pay — for the single span and for the weekly total. So 8.00 hours at 18.50 an hour is 148.00. This is a before-tax estimate that does not apply overtime multipliers, tax or other deductions, so treat it as a quick guide rather than a payslip.

Hours Calculator

The Hours Calculator works out how many hours are between a start time and an end time — perfect for timesheets, shifts and billing. Enter your clock-in and clock-out, subtract a break, and it shows the total as decimal hours (the format payroll uses, where 8 hours 30 minutes is 8.50) and as hours a…

HOW TO USE

1
Enter your start time and end time.
2
Add any break in minutes to subtract it from the total.
3
Read the result as decimal hours and hours:minutes — overnight shifts are handled automatically.
4
Optionally add an hourly rate for pay, and use the weekly time card to total several days.

HOW THE HOURS ARE CALCULATED

The calculator finds the minutes between your start and end times, then subtracts any break. If the end time is earlier than the start time, it assumes the shift runs past midnight into the next day and adds 24 hours, so an overnight shift like 22:00 to 06:00 correctly reads eight hours. The result is shown two ways: as decimal hours, which is what payroll usually needs (8 hours 30 minutes is 8.50), and as hours and minutes. Enter an hourly rate to turn the decimal hours into pay, and use the weekly card to total several days at once.

WHAT PEOPLE USE IT FOR

Study & activity logs

Track how many hours you spent on a task between two times, with breaks removed.

FREQUENTLY ASKED QUESTIONS

Enter a start time and an end time, and the calculator returns the number of hours between them, minus any break. It finds the minutes from start to end and divides by 60, showing the result both as decimal hours and as hours and minutes. Doing this by hand is fiddly because you have to convert across the 60-minute boundary, so the tool handles the arithmetic — including shifts that cross midnight.

Enter the start and end times; add a break if needed.
The result appears as decimal hours (e.g. 8.50) and as 8h 30m.
Minutes are converted to hours by dividing by 60.
Overnight spans are detected and handled automatically.

NOTES & REFERENCES

Decimal hours = total minutes ÷ 60, so 90 minutes is 1.50 hours; this is the format most payroll systems use.
If the end time is on or before the start time, an overnight shift is assumed and 24 hours are added.
Break time is subtracted from the clock span; the result is never negative.
Pay is an estimate: decimal hours × your rate, before tax, overtime rules or deductions.
