Night Shift Calculator
Calculate your overnight shift hours, unpaid break time, paid hours and estimated pay.
What Is a Night Shift Calculator?
A Night Shift Calculator helps you calculate how many hours you worked when your shift crosses midnight.
For example, if your shift starts at 11:00 PM and ends at 7:00 AM, the calculator understands that the end time is on the following day.
It can also deduct unpaid break time and show your paid working hours. If you enter an hourly rate, it can estimate your shift pay as well.
How to Use the Night Shift Calculator
Using the calculator is simple:
- Enter your shift start time.
- Enter your shift end time.
- Enter any unpaid break you took during the shift.
- Choose whether the shift ends on the same day or next day / overnight.
- Enter your hourly rate and select your currency if you want to estimate your earnings.
- Click Calculate My Shift.
The calculator will show:
- Total shift length
- Unpaid break time
- Paid working hours
- Decimal hours
- Estimated pay
Night Shift Calculation Example
Suppose your shift starts at 11:00 PM and finishes at 7:00 AM the next morning.
Your total shift length is 8 hours.
If you take a 30-minute unpaid break, your paid working time becomes 7 hours 30 minutes.
In decimal format, this is 7.50 hours.
If your hourly rate is €15, your estimated pay would be €112.50.
7.50 × €15 = €112.50
How Are Overnight Shift Hours Calculated?
Overnight shifts need to be treated differently from normal same-day shifts because the end time falls after midnight.
For example:
- Start: 10:00 PM
- End: 6:00 AM
The calculator treats 6:00 AM as the following day, giving a total shift length of 8 hours.
Without this adjustment, a standard time calculation could incorrectly treat the end time as being earlier than the start time.
If you work overnight shifts with several paid or unpaid breaks, use the Overnight Shift Calculator for a more detailed calculation.
How Do Unpaid Breaks Affect Your Working Hours?
An unpaid break is deducted from your total shift length when calculating your paid hours.
For example:
- Total Shift: 9 hours
- Unpaid Break: 45 minutes
- Paid Working Time: 8 hours 15 minutes
If your break is paid, you can enter 0 minutes in the unpaid break field.
If you need more control over paid and unpaid breaks, use the Shift Calculator With Break .
What Are Decimal Hours?
Decimal hours express working time as a decimal number instead of hours and minutes.
This format can be useful for timesheets, payroll calculations and estimating hourly earnings.
| Hours and Minutes | Decimal Hours |
|---|---|
| 7 hours 15 minutes | 7.25 |
| 7 hours 30 minutes | 7.50 |
| 7 hours 45 minutes | 7.75 |
| 8 hours | 8.00 |
For example, 30 minutes equals 0.50 hours because 30 minutes is half of one hour.
Night Shift Pay Calculation
If you are paid by the hour, your estimated night shift pay can be calculated using:
Paid Hours × Hourly Rate = Estimated Pay
For example:
- Paid Hours: 8.25
- Hourly Rate: €16
8.25 × €16 = €132.00
The ShiftCalco Night Shift Calculator can calculate this automatically when you enter your hourly rate.
The result is an estimate only. Your actual pay may differ if your employer applies overtime, night premiums, weekend rates, holiday rates, taxes or other deductions.
For overtime calculations, use the Overtime Calculator . For premiums and bonuses on an individual shift, use the Shift Pay Calculator .
Same-Day Shift vs Overnight Shift
A same-day shift starts and ends on the same calendar day.
For example: 9:00 AM to 5:00 PM.
An overnight shift continues into the next calendar day.
For example: 11:00 PM to 7:00 AM.
When using the Night Shift Calculator, select Next Day / Overnight if your shift continues past midnight.
For a standard daytime or same-day shift, you can use the Shift Hours Calculator .

It can be useful for people working in:
- Hotels and hospitality
- Hospitals and healthcare
