UAE Overtime Calculation Rules, Worked Through With Real Numbers

The UAE overtime calculation rules that actually apply

A branch manager comes to you on a Wednesday: the delivery backlog needs three people staying two hours past close, and the Ramadan rush means a Thursday closing shift is running past midnight. Before you approve either one, you need the uae overtime calculation rules that actually govern what those extra hours cost, not the rounded-off version that gets repeated across HR blogs. Under Federal Decree-Law No. 33 of 2021 (the current UAE Labour Law), overtime is not a single flat rate. It splits by when the hours fall, it caps at two hours a day, and it is calculated on basic salary only, never on the total package the employee sees on their offer letter.

Article 19 sets the baseline: an employee asked to work beyond their normal hours is owed their basic hourly wage plus at least 25% for ordinary overtime. If those hours fall between 10pm and 4am, the uplift rises to at least 50%. The same article limits overtime to two hours per day, except where the work is needed to prevent a substantial loss, a serious accident, or to address an urgent operational need, in which case the cap can be exceeded but the pay does not change. None of this touches allowances. Housing, transport, and other benefits sit outside the calculation entirely, which is the detail that trips up new payroll clerks most often.

Turning a monthly basic salary into an hourly rate

Every overtime figure starts with an hourly rate, and the UAE convention is to treat a month as 30 days and a day as 8 hours. So the formula is:

Hourly rate = basic monthly salary ÷ 30 ÷ 8

An employee on a basic salary of AED 4,500 has an hourly rate of 4,500 ÷ 30 ÷ 8 = AED 18.75. From there:

• Ordinary overtime pays at least 18.75 × 1.25 = AED 23.44 per hour.
• Night overtime (10pm to 4am) pays at least 18.75 × 1.50 = AED 28.13 per hour.

Some calculators use 365 ÷ 12 ÷ 8 instead of 30 ÷ 8 for the daily divisor, which produces a daily figure of roughly 30.42 days rather than 30. The difference between the two is small (about 1.4%) but it is not zero, and if your payroll system quietly picks one convention while your attendance system assumes the other, every overtime line on every payslip will be off by a few cents that compound into a real reconciliation problem across a few hundred employees. Pick one divisor, write it into your payroll policy, and use it consistently across every branch.

A full worked example across one pay cycle

This is the part most guides skip. Take that same employee, basic salary AED 4,500, across one week that includes a backlog night and a Friday shift.

Tuesday: stays 3 hours past closing to finish a stock count. Ordinary overtime: 3 × 23.44 = AED 70.31.

Wednesday: covers a delayed delivery that runs from 9pm to midnight, 2 hours of which fall after 10pm. Ordinary overtime (9 to 10pm): 1 × 23.44 = AED 23.44. Night overtime (10pm to midnight): 2 × 28.13 = AED 56.25.

Friday: the branch's designated weekly rest day. The employee is called in for a 6-hour shift and is not given a substitute day off. Friday work is governed separately, by Article 21, not by the overtime uplift in Article 19. Article 21 entitles a worker required to work on the weekly rest day to either a compensatory day off, or the day's ordinary wage plus a premium of at least 50% of the basic wage for that day, if no substitute day is granted. Article 28 sets out the same remedy for official public holidays, which is why the two are so often merged into one rule. The day's ordinary wage is 4,500 ÷ 30 = AED 150. The premium is at least 150 × 0.5 = AED 75. Total for the Friday shift: AED 225, and this is on top of, not instead of, the hours actually worked that day.

Add it up: AED 70.31 + AED 23.44 + AED 56.25 + AED 225 = AED 375 in overtime and rest-day pay for that single week, on top of the AED 4,500 base. None of it touches allowances, and every figure traces back to a specific article rather than a rule of thumb.

Where the two "150%" figures get confused

Search for uae overtime calculation rules and you will find two different numbers both described as "150%", and most pages do not explain that they come from different articles and apply to different things.

The first 150% is the night overtime rate under Article 19: the employee's basic hourly wage plus a 50% uplift, applied only to the hours actually worked between 10pm and 4am.

The second is the weekly rest-day rule under Article 21, mirrored by Article 28 for official public holidays: the day's ordinary wage (100%) plus a 50% premium, which totals 150% of that day's basic wage, but it applies to the whole day worked, not to an hourly overtime rate, and it comes with an alternative of a substitute day off that the night-overtime rule does not offer.

Treat them as the same number and you will either underpay a night-shift worker who also picked up a rest-day shift, or overpay by stacking a rate that was never meant to combine. The two provisions can both apply in the same week, as the worked example above shows, but they never apply to the same hour.

The two-hour cap and the 144-hour ceiling that multi-branch teams miss

Article 19 caps ordinary overtime at two hours a day. In a single-location business, one supervisor tracking one whiteboard can enforce that by eye. Across three, five, or fifteen branches, each running its own closing routine and its own idea of who covers a gap, the two-hour cap is the first rule that quietly breaks, because nobody at head office sees the pattern until a labour complaint or a wage protection system flag forces the question.

The law also caps total working hours, ordinary plus overtime, at 144 hours over any three-week period. That is an average, not a per-day rule, which means a branch can run a heavy week during a promotion or a stocktake as long as it is balanced by a lighter one within the same rolling window. Tracking that by branch, let alone across a company, is not something a paper register or a set of disconnected spreadsheets can do reliably. It is one of the concrete reasons attendance data needs to live in one system rather than one per branch, the same argument covered in how automated timesheets close the payroll reconciliation gap that manual systems create.

What this means for how you run payroll

None of the arithmetic above is difficult on its own. The problem is scale and consistency: the same two-hour cap, the same divisor, the same distinction between Article 19 and Articles 21 and 28, applied correctly across every branch, every week, without a payroll clerk having to remember which rule applies to which shift. That is a policy decision as much as a payroll one, and it belongs in the same policy document as your leave management rules, not scattered across branch-level habits.

FAQ

Is overtime calculated on basic salary or total salary in the UAE?
Basic salary only. Housing allowance, transport allowance, and any other benefits are excluded from the hourly rate used for overtime, under Article 19 of Federal Decree-Law No. 33 of 2021.

Can an employer require more than two hours of overtime in a day?
Only where it is needed to prevent a substantial loss, a serious accident, or an urgent operational need. Outside those circumstances, the daily cap is two hours, though the total working week is also bounded by the 144-hour ceiling over three weeks.

Does Friday overtime pay 150% under UAE labour law?
Not exactly. Working on the designated weekly rest day falls under Article 21, not the overtime uplift in Article 19, and Article 28 covers official public holidays on the same terms. The employer owes either a substitute day off, or the day's ordinary wage plus a premium of at least 50%, which totals 150% of that day's basic wage. It is a different provision from the 150% night overtime rate, even though the number looks the same.

What counts as night overtime hours?
Hours worked between 10pm and 4am carry the higher, at-least-50%, uplift under Article 19. Hours worked outside that window, even late in the evening, are ordinary overtime at the at-least-25% rate.

Conclusion

The arithmetic in this piece is not the hard part. Deciding, in writing, which divisor your company uses for the hourly rate, which article applies to a given shift, and how a two-hour daily cap gets enforced across branches that do not share a supervisor is the actual decision in front of you. Get that policy settled once, put it in the same system that already tracks who clocked in where, and the payslip stops being where the argument happens.
