What is night differential?
For covered private-sector employees, night shift differential is generally an additional amount for qualifying work performed during the statutory night period, commonly 10:00 PM to 6:00 AM.
The basic idea is simple: identify the hours actually worked inside the qualifying night window, determine the applicable hourly base, then apply the night differential percentage. Company policy, collective agreements or other rules may provide a better rate than the statutory minimum.
Basic night differential formula
A simplified statutory-minimum estimate for an ordinary qualifying hour is:
This is only the additional night premium. It is not necessarily the employee's entire wage for those hours. If overtime, rest-day or holiday premiums also apply, the calculation can become more complex.
Which hours count?
Under the rule modeled by PaycheckPH, the qualifying window is generally 10:00 PM to 6:00 AM. A shift does not need to begin at 10 PM. Only the portion that overlaps the night window is counted.
Example: if an employee works from 9:00 PM to 5:00 AM, the ordinary night-window overlap is seven hours, from 10:00 PM through 5:00 AM, before considering unpaid breaks.
Remember to subtract unpaid breaks
Night differential is based on compensable work time. If an unpaid meal or rest break occurs inside the night window, that break generally should not be counted as worked night hours in a simple estimate.
What if the night work is also overtime or on a holiday?
Multiple premiums can interact. Night differential may apply together with overtime, rest-day, special-day or regular-holiday pay depending on the situation and employee coverage. In those cases, use the applicable day and overtime rules rather than simply adding 10% to a normal hourly rate without checking the base.

Frequently asked questions
What time does night differential start in the Philippines?
For covered employees under the rule modeled here, the statutory night-work window is generally 10:00 PM to 6:00 AM.
What is the minimum night differential rate?
The statutory minimum for covered private-sector employees is generally an additional 10% of the regular wage for each qualifying night hour, subject to coverage rules.
Does a shift crossing midnight qualify?
Yes, the relevant question is how much of the shift overlaps the qualifying night period. A shift can begin before 10 PM or end after midnight and still contain qualifying night hours.
Does night differential apply with overtime?
It can. When night work is also overtime, on a rest day or on a holiday, multiple premiums may interact and the correct base should be verified.
Worked shift examples
For an employee with a ₱1,200 daily rate, a simplified hourly rate is ₱150. If eight paid hours fall entirely inside the 10:00 PM to 6:00 AM statutory window, a 10% night differential adds ₱150 × 10% × 8 = ₱120. If only four paid hours overlap the window, the additional amount under the same simplified assumptions is ₱60.
Only overlapping hours count
A shift does not need to begin at 10:00 PM to qualify. What matters for the simple calculator is how many paid working hours overlap the statutory window. Breaks that are not compensable should not be counted as qualifying work time.
Night differential is separate from other premiums
Night work can occur on an ordinary day, rest day or holiday. In real payroll, the applicable base pay and other premiums may need to be determined before the night differential is added. Do not assume that the 10% night differential replaces overtime, rest-day or holiday pay.
Checklist before comparing with payroll
- Confirm the basic hourly rate.
- Identify the paid hours that actually fall between 10:00 PM and 6:00 AM.
- Remove unpaid break time where appropriate.
- Check whether the employer provides a rate higher than the statutory minimum.
- Check whether another premium applies to the same hours.
