How to Calculate End of Service Gratuity in UAE: Article 51 Formula (21-Day & 30-Day Tiers With Exact Examples)
Under Article 51 of UAE Federal Decree-Law No. 33 of 2021 (Regulating Labour Relations in the Private Sector), every full-time foreign employee who completes 1 full continuous year (365 calendar days) of service is legally entitled to a lump-sum End of Service Gratuity (EOSB) upon contract termination. The statutory formula awards 21 calendar days of Basic Salary per year for the first 5 years of service, and 30 calendar days of Basic Salary per year for every subsequent year beyond 5 years.

- Beyond 5 Years of Service (Year 6+): 30 days of Basic Salary (1 full month's Basic Salary) for each subsequent year — equal to (Basic Salary ÷ 30) × 30 per year.
- Exact Calendar Day Proration & Cap: Partial years after completing Year 1 are prorated down to the exact calendar day worked, and total gratuity is capped at 2 years' total wage (24 months).

1. The Exact Step-by-Step Article 51 Gratuity Formula
Under Article 51 of Federal Decree-Law No. 33 of 2021, UAE End of Service Gratuity is calculated strictly on your last drawn Basic Monthly Salary (excluding housing, transport, utilities, and education allowances — see our Basic Salary vs. Commissions Guide):
- Daily Basic Wage:
Daily Basic = Basic Monthly Salary ÷ 30 - Annual Gratuity for Years 1 to 5 (First 1,825 Days):
Annual Tier 1 = Daily Basic × 21(which equals 70% of one month's basic salary per year). - Annual Gratuity for Year 6 Onward (Days Beyond 1,825):
Annual Tier 2 = Daily Basic × 30(which equals 100% of one month's basic salary per year). - Proration of Partial Years (Article 51(4)): Once you cross 365 days, every additional month and day is prorated by dividing by 365 days.

2. Tier 1 Example: 3 Years & 6 Months of Service (21-Day Rule)
Suppose an engineer in Dubai earns a Basic Salary of AED 12,000/month (out of a total AED 20,000 package) and leaves after working 3.5 years (1,277.5 days):
- Daily Basic Wage =
12,000 ÷ 30 = AED 400 / day - 21-Day Annual Entitlement =
400 × 21 = AED 8,400 / year - Total Gratuity for 3.5 Years =
8,400 × 3.5 = AED 29,400
3. Tier 2 Split Example: 7 Years of Service (21-Day + 30-Day Split)
A common misconception is that once you pass 5 years of service, all your years are recalculated at 30 days/year. That is incorrect: the first 5 years are always calculated at 21 days/year, and only the years after Year 5 are calculated at 30 days/year. For a manager with a Basic Salary of AED 15,000/month leaving after 7 full years:
- Daily Basic Wage =
15,000 ÷ 30 = AED 500 / day - First 5 Years (Tier 1 @ 21 days):
5 years × (500 × 21) = 5 × 10,500 = AED 52,500 - Years 6 & 7 (Tier 2 @ 30 days):
2 years × (500 × 30) = 2 × 15,000 = AED 30,000 - Total Final Gratuity = AED 82,500 (plus unused annual leave encashment!).
4. The 2-Year Wage Statutory Maximum Cap (Article 51(7))
Under Article 51(7) of Federal Decree-Law No. 33 of 2021, the aggregate End of Service Gratuity paid to an employee may not exceed two (2) years' wage (24 months), typically reached after ~25.5 years of continuous service with the same employer.
5. Mainland/Free Zone vs. DIFC (DEWS) & ADGM Employment Law
Note that Article 51 of Federal Decree-Law No. 33 of 2021 governs all UAE Mainland companies and 95% of UAE Free Zones (DMCC, JAFZA, DIC, DMC, DAFZA, IFZA, Shams, etc.). The only exceptions are the two financial common-law free zones: DIFC (which replaced traditional lump-sum gratuity with the DIFC Employee Workplace Savings (DEWS) plan contributing 5.83% to 8.33% monthly) and ADGM (which follows the ADGM Employment Regulations 2019 using a similar 21-day/30-day formula).
