Night shift differential (NSD) is at least 10% of your regular hourly wage for every hour actually worked between 10:00 p.m. and 6:00 a.m., under Article 86 of the Labor Code. The basic formula is: hourly rate × 10% × number of night hours worked, and this premium stacks on top of overtime, rest day, or holiday pay when those overlap with the night shift window.
If part or all of your shift falls between 10:00 p.m. and 6:00 a.m., you are entitled to extra pay for those hours on top of your regular wage. This is called night shift differential, or NSD, and it is one of the more mechanical benefits to compute once you know your hourly rate — the tricky part is usually figuring out how it interacts with overtime, rest days, and holidays.
The Legal Basis: Article 86 of the Labor Code
Article 86 of the Labor Code provides that every employee shall be paid a night shift differential of not less than ten percent (10%) of their regular wage for each hour of work performed between ten o’clock in the evening and six o’clock in the morning. The key word is "regular wage" — NSD is computed on your basic hourly rate, not on allowances, and it is paid only for hours actually worked within that eight-hour window, not for your entire shift if only part of it falls at night.
Who is covered
NSD applies to rank-and-file employees regardless of position title, as long as their work is not among the categories excluded from the hours-of-work provisions of the Labor Code. Those exclusions cover managerial employees, officers or members of a managerial staff, field personnel whose hours cannot be determined with reasonable certainty, workers paid purely by results, and members of the employer’s family dependent on the employer for support. Domestic workers are not covered by Article 86 at all — kasambahay pay and rest rules are governed separately under the Domestic Workers Act, Republic Act No. 10361.
The Basic Formula
The plain NSD computation is:
- Hourly rate × 10% × number of hours worked between 10:00 p.m. and 6:00 a.m.
To get your hourly rate:
- Daily-paid employees: daily rate ÷ 8 hours
- Monthly-paid employees: divide the monthly rate by the number of paid days in the applicable period used by your employer’s payroll (commonly the monthly rate × 12 months ÷ the employer’s applicable annual working/paid days), then divide that daily rate by 8. The exact divisor can differ slightly between companies depending on whether rest days and holidays are already factored into the monthly rate, so check your payslip or employment contract for the divisor your employer actually uses.
Example: An employee earning ₱610 for an 8-hour day has an hourly rate of ₱76.25. If they work a full shift from 10:00 p.m. to 6:00 a.m. (8 night hours), their NSD for that shift is ₱76.25 × 10% × 8 = ₱61.00, on top of their regular day’s wage of ₱610.00.
If only part of the shift falls within the night window — say a 4:00 p.m. to 12:00 midnight shift — only the hours from 10:00 p.m. to midnight (2 hours) are subject to NSD; the earlier hours are paid at the regular rate.
Combining NSD With Overtime, Rest Days, and Holidays
NSD does not replace other premiums — it stacks with them. Following the multiplier method used in DOLE’s own guide computations in its Handbook on Workers’ Statutory Monetary Benefits:
NSD plus overtime
If night-shift hours are also overtime hours (beyond 8 hours worked that day), the hourly rate is multiplied by both the night shift premium and the overtime premium: 1 × 1.10 × 1.25 = 1.375, meaning those hours are paid at 137.5% of the basic hourly rate.
Worked example: Using the same ₱76.25 hourly rate, suppose two of the employee’s eight night hours are also overtime hours because the employee worked beyond a regular 8-hour shift. Those two hours are paid at ₱76.25 × 1.375 = ₱104.84 per hour, while the remaining six night hours that are not overtime are paid at the plain night rate of ₱76.25 × 1.10 = ₱83.88 per hour.
NSD on a rest day
If the night hours are worked on the employee’s scheduled rest day, the rest-day premium (at least 130% of the basic rate) combines with the night differential: 1.30 × 1.10 = 1.43, or 143% of the basic hourly rate.
NSD on a regular holiday
Using the same multiplier logic, night hours worked on a regular holiday (paid at 200% of the basic rate) carry a night differential of 200% × 1.10 = 220% of the basic hourly rate for those specific hours.
NSD on a special non-working day
Special non-working days are usually declared by presidential proclamation. The default rule for a special non-working day is "no work, no pay," but an employee who does report for work is generally entitled to an additional 30% of the daily rate for the first eight hours, similar to the rest-day premium described above. When night hours are worked on a special non-working day, the same layering applies: 1.30 × 1.10 = 1.43, or 143% of the basic hourly rate for those specific hours.
In every case, the night differential is layered on top of whatever premium already applies to that hour — it is calculated last, as a percentage of the already-adjusted rate for that hour, not simply added as a flat 10% of the base rate.
Common Computation Mistakes
- Applying NSD to the whole shift instead of only the hours that actually fall between 10:00 p.m. and 6:00 a.m.
- Computing NSD on the wrong base — using the daily rate instead of the hourly rate, or including allowances that should not form part of the "regular wage" base.
- Forgetting to stack premiums when night hours coincide with overtime, a rest day, or a holiday, resulting in underpayment.
- Assuming a flat monthly "night differential allowance" satisfies the law even when it consistently computes to less than 10% of the hours actually worked at night — a company policy cannot go below the Article 86 floor.
Keeping Proof of Your Night Hours
Because NSD is paid only for hours actually worked within the 10:00 p.m. to 6:00 a.m. window, the strength of any claim usually comes down to your own records. Daily time records, biometric logs, shift schedules issued by your supervisor, and messages confirming your reporting and log-out times are all useful evidence if a dispute arises. Keep your own copies rather than relying solely on your employer’s system, since access to company records can become difficult once a dispute starts.
NSD Under a Company Policy or CBA
Article 86 sets a floor, not a ceiling. Many companies, particularly those with a collective bargaining agreement, voluntarily pay a night differential higher than 10%, or extend the premium to hours slightly outside the statutory window as a matter of policy. A company policy or CBA provision that grants a more generous rate remains enforceable as a contractual benefit even though it exceeds what the law requires; what a policy cannot do is pay less than the statutory 10% floor for hours that do fall within 10:00 p.m. to 6:00 a.m., regardless of what the policy says.
Special Cases: Split Shifts and Compressed Workweeks
Employees on a compressed workweek or a split-shift schedule are still entitled to NSD for whatever portion of their actual hours worked falls between 10:00 p.m. and 6:00 a.m., computed the same way as a standard shift. A compressed workweek arrangement, where an employee works longer hours over fewer days, does not by itself change the night differential rules; each hour is still evaluated individually against the 10:00 p.m. to 6:00 a.m. window and against whichever other premiums, such as overtime, rest day, or holiday pay, apply to that specific hour.
Night Shift Differential for Remote and Field-Based Work
The same 10% floor applies to remote or work-from-home employees whose required schedule falls, in whole or in part, within the 10:00 p.m. to 6:00 a.m. window, provided their actual hours worked can be determined with reasonable certainty. This is the same test the Labor Code uses to decide who is covered at all — employees whose hours genuinely cannot be verified, such as certain field-based roles, fall outside Article 86 entirely, while those whose logins, call logs, or output are time-stamped generally remain covered even when they never set foot in an office.
If You Believe You Were Underpaid
Night shift differential is treated the same as any other money claim: you can raise it with your employer directly, or file a Request for Assistance under the Single Entry Approach (SEnA) at the nearest DOLE office, which starts a free 30-day conciliation-mediation process before any formal case is needed. Keep your daily time records or biometric logs, since these are usually the best evidence of exactly how many hours you actually worked within the 10:00 p.m. to 6:00 a.m. window.
Frequently Asked Questions
Is night shift differential the same as a graveyard shift allowance? Not necessarily. Night shift differential is a specific statutory premium of at least 10% of the hourly rate for hours worked between 10:00 p.m. and 6:00 a.m. under Article 86 of the Labor Code, while a "graveyard shift allowance" is a company-created benefit that must still, at minimum, satisfy the Article 86 floor for actual night hours worked.
Do managers and supervisors get night shift differential? Generally no. Employees classified as managerial employees or members of the managerial staff are excluded from the hours-of-work provisions of the Labor Code, which includes the night shift differential rule, though many employers still grant an equivalent benefit as company policy.
Does night shift differential apply to work-from-home employees? Yes, if the employee is a rank-and-file worker whose actual hours can be determined and part of their required work schedule falls between 10:00 p.m. and 6:00 a.m., the same 10% premium applies regardless of whether the work is performed at the office or at home.
How do I compute my hourly rate if I am paid monthly? Divide your monthly salary by the number of paid days your employer uses for payroll purposes to get a daily rate, then divide that daily rate by 8 to get your hourly rate; check your payslip or employment contract, since the exact divisor can vary by employer.
