Gratuity Calculation Formula UAE 2026 | 21 & 30 Day Method
The UAE gratuity calculation formula is (Basic Salary ÷ 30) × 21 days × service years for the first 5 years, then 30 days per year after, under Article 51 of Federal Decree-Law No. 33 of 2021. A worker earning AED 8,000 basic over 3 years receives (8,000 ÷ 30) × 21 × 3 = AED 16,800. This guide breaks down every formula — limited contracts, partial years, salary changes, the 2-year cap — with worked AED examples you can verify against your own settlement.
What Is the UAE Gratuity Calculation Formula?
The UAE gratuity calculation formula computes end-of-service benefits from three variables: basic salary, service duration, and contract type. Article 51 of Federal Decree-Law No. 33 of 2021 sets the rates that produce your exact payment.
The formula converts service years into days of basic salary. The standard rate is 21 days per year for the first 5 years, then 30 days per year after. Calculation methods differ between limited contracts and unlimited contracts, and the total cannot exceed the two-year salary cap under Article 51(7).
Understanding the formula lets you verify your settlement independently and catch employer underpayment before you accept a final figure.
What Are the Basic Components of the Gratuity Formula?
The gratuity formula uses three components: basic salary, service duration, and the daily rate.
Basic Salary Component
Basic salary is your fixed monthly wage, excluding allowances. Article 51 of UAE Labour Law calculates gratuity on basic salary only. Housing, transport, phone allowances, and performance bonuses do not count.
The formula applies your final basic salary to all service years. A salary increase before you leave raises your entire gratuity, because the last drawn basic wage sets the rate.
Service Duration Component
Service duration counts years and months from your first working day to your last working day. Complete years calculate at full rates, and partial years receive pro-rata amounts under Article 51(3).
Service includes your notice period and paid leave. Article 51(2) excludes only unpaid absence from the count. Probation periods count toward your total service once you complete one year of employment.
Daily Rate Component
The daily rate divides your monthly basic salary by 30. Formula: Daily Rate = Basic Salary ÷ 30. UAE Labour Law uses 30-day months for every gratuity calculation, regardless of actual calendar days.
What Is the Limited Contract Gratuity Formula?
The limited contract formula pays 21 days of salary per year for the first 5 years, then 30 days per year after. The same rates apply whether you resign or face termination, for all service from February 2, 2022. For a full walkthrough, see our step-by-step gratuity guide.
Limited Contract Formula: Years 1 to 5
Gratuity = (Service Years × 21 days × Basic Salary) ÷ 30
- Service Years: complete years plus partial years as decimals
- 21 days: the rate for the first 5 years
- Basic Salary: monthly basic wage in AED
- 30: the conversion divisor for monthly equivalents
Example, 3 years service, AED 8,000 basic:
Formula: (3 × 21 × 8,000) ÷ 30
Result: 504,000 ÷ 30 = AED 16,800
Limited Contract Formula: Year 6 Onward
Gratuity = (Service Years × 30 days × Basic Salary) ÷ 30
The rate rises from 21 to 30 days after you complete 5 years. The two-year salary cap applies to the total.
Example, 8 years service, AED 10,000 basic:
Years 1-5: (5 × 21 × 10,000) ÷ 30 = AED 35,000
Years 6-8: (3 × 30 × 10,000) ÷ 30 = AED 30,000
Total Gratuity: AED 65,000
What Was the Unlimited Contract Resignation Formula? (Pre-Feb 2022)
The unlimited contract resignation formula reduced gratuity by a fraction of the standard 21-day rate, for service completed before February 2, 2022. Federal Decree-Law No. 33 of 2021 abolished this reduction. The fractions below apply only to legacy unlimited-contract service under the repealed Federal Law No. 8 of 1980 (Article 137).
Under the current law, resignation and termination earn identical gratuity for all service from February 2, 2022. The fractions are historical only.
Resignation Formula: Years 1 to 3 (One-Third)
Gratuity = [(Service Years × 21 days × Basic Salary) ÷ 30] × 1/3
The first three years earned one-third of the standard 21-day amount.
Example, 2 years service, AED 9,000 basic:
Standard amount: (2 × 21 × 9,000) ÷ 30 = AED 12,600
Reduced (1/3): 12,600 × 1/3 = AED 4,200
Resignation Formula: Years 3 to 5 (Two-Thirds)
Gratuity = [(Service Years × 21 days × Basic Salary) ÷ 30] × 2/3
Service in the 3-to-5-year band earned two-thirds of the standard amount.
Example, 4 years service, AED 8,000 basic:
Standard amount: (4 × 21 × 8,000) ÷ 30 = AED 22,400
Reduced (2/3): 22,400 × 2/3 = AED 14,933
Resignation Formula: Beyond 5 Years (Full Rate)
Gratuity = (21 days × first 5 years + 30 days × additional years) × Basic Salary ÷ 30
Service beyond 5 years earned the full rate, matching the limited contract formula.
Example, 7 years service, AED 12,000 basic:
Years 1-5: (5 × 21 × 12,000) ÷ 30 = AED 42,000
Years 6-7: (2 × 30 × 12,000) ÷ 30 = AED 24,000
Total Gratuity: AED 66,000
What Is the Unlimited Contract Termination Formula?
The unlimited contract termination formula matches the limited contract rates. Employer-initiated termination paid full gratuity with no reduction.
Years 1-5: Gratuity = (Service Years × 21 days × Basic Salary) ÷ 30
Year 6 onward: add (Additional Years × 30 days × Basic Salary) ÷ 30
Termination always paid the full rate. The reduction applied only to voluntary resignation on pre-2022 unlimited contracts.
How to Calculate Partial Service Years
Partial years receive pro-rata gratuity under Article 51(3). The formula converts months into decimal years.
Decimal Years = Complete Years + (Months ÷ 12)
- 3 months = 0.25 years
- 6 months = 0.5 years
- 9 months = 0.75 years
- 15 months = 1.25 years
- 18 months = 1.5 years
Example, 4 years 8 months service, AED 10,000 basic, limited contract:
Conversion: 4 + (8 ÷ 12) = 4.67 years
Formula: (4.67 × 21 × 10,000) ÷ 30
Result: 980,700 ÷ 30 = AED 32,690
What Is the Maximum Gratuity Cap?
The maximum gratuity caps at two years of basic salary, regardless of service length. Formula: Maximum = Basic Salary × 24 months. Article 51(7) sets this limit.
Long-service employees reach the cap after roughly 20 to 24 years, depending on salary. You receive the calculated amount when it sits below the cap, and the capped amount when it exceeds it.
Example, 20 years service, AED 15,000 basic, limited contract:
Years 1-5: (5 × 21 × 15,000) ÷ 30 = AED 52,500
Years 6-20: (15 × 30 × 15,000) ÷ 30 = AED 225,000
Calculated total: AED 277,500
Maximum cap: 15,000 × 24 = AED 360,000
Payment: AED 277,500 (under the cap)
Example, 25 years service, AED 20,000 basic, limited contract:
Years 1-5: (5 × 21 × 20,000) ÷ 30 = AED 70,000
Years 6-25: (20 × 30 × 20,000) ÷ 30 = AED 400,000
Calculated total: AED 470,000
Maximum cap: 20,000 × 24 = AED 480,000
Payment: AED 470,000 (under the cap)
How to Calculate Combined Service Periods
Service that crosses the 5-year threshold splits into segments. You calculate each segment at its rate, then sum the results.
Limited Contract Combined Formula
Total Gratuity = [Years 1-5 at 21 days] + [Years 6+ at 30 days]
Example, 9 years service, AED 11,000 basic:
Period 1: (5 × 21 × 11,000) ÷ 30 = AED 38,500
Period 2: (4 × 30 × 11,000) ÷ 30 = AED 44,000
Total: AED 82,500
Pre-2022 Unlimited Resignation Combined Example
For legacy unlimited-contract resignation beyond 5 years, the full rate applied because the worker passed the 5-year threshold.
Example, 8 years service, AED 9,500 basic:
Years 1-5: (5 × 21 × 9,500) ÷ 30 = AED 33,250
Years 6-8: (3 × 30 × 9,500) ÷ 30 = AED 28,500
Total: AED 61,750
How Does a Salary Change Affect the Formula?
A salary change applies your final basic salary to all service years. The formula uses your last drawn basic wage for the entire calculation.
Example, 6 years at AED 7,000 then 2 years at AED 10,000 basic:
Total service: 8 years
Formula uses: AED 10,000 (final salary)
Years 1-5: (5 × 21 × 10,000) ÷ 30 = AED 35,000
Years 6-8: (3 × 30 × 10,000) ÷ 30 = AED 30,000
Total: AED 65,000
A salary increase before you leave raises your full gratuity, since the final basic wage sets the rate for every year of service.
What Common Formula Mistakes Should You Avoid?
Calculation errors commonly reduce gratuity payments. The four most frequent mistakes follow.
Mistake 1: Using Total Package Instead of Basic Salary
The formula uses basic salary only. A package of AED 15,000 with a basic salary of AED 7,000 calculates at AED 7,000. Using the package figure overstates the result. MOHRE validates basic salary from the registered contract.
Mistake 2: Applying the Wrong Rate Threshold
The 5-year mark triggers the rate change. A worker who completes 5 years and 2 months earns 21 days for the first 5 years, then 30 days for the partial sixth year. Applying the 21-day rate to year 6 underpays the worker.
Mistake 3: Ignoring Partial Years
Partial years calculate pro-rata. Service of 4 years 9 months equals 4.75 years, not 4. Dropping those 9 months loses 0.75 × 21 = 15.75 days of gratuity.
Mistake 4: Confusing Resignation with Termination on Old Contracts
Pre-2022 unlimited contracts used reduced fractions for resignation but full rates for termination. Applying the wrong basis underpays the worker. For all service from February 2022, both produce the same amount.

Frequently Asked Questions
Does the formula use 30 or 365 days?
The formula uses 30-day months. UAE Labour Law applies a 30-day conversion regardless of actual calendar days. Every month counts as 30 days, so Days ÷ 30 produces the monthly equivalent.
What if my service spans multiple salary levels?
The formula uses your final basic salary for all service years. Historical salary levels do not affect the calculation. A salary increase during service raises your full gratuity.
How does the formula handle leap years?
The formula ignores leap years. Every year converts into 30-day months, so the extra leap day does not change the result.
Can the formula produce fractional AED amounts?
Yes. The formula produces exact decimal results, rounded to the nearest fils. Employers pay the exact calculated amount.
What if the formula exceeds the two-year maximum?
Payment caps at two years of basic salary. When the calculated amount exceeds 24 months of basic salary, you receive the capped figure under Article 51(7).
Does probation affect the formula?
Probation counts toward your total service once you complete one year of employment. The probation months are included in the service period used by the formula.
How does the formula handle mid-month termination?
Partial months calculate pro-rata within the service period. The calculator converts your exact dates into decimal years for a precise figure.
Can I verify my employer’s calculation?
Yes. Your contract gives your basic salary and service dates. Apply the formula to confirm the expected amount. A discrepancy supports a MOHRE complaint with calculation evidence.
