The formula
How UAE gratuity is calculated: 21 and 30 days
The calculation has four moving parts, and the calculator applies them in order. Understanding each one lets you check any gratuity figure by hand.
1. The daily wage. Gratuity is expressed in days of pay, so the first step is converting your monthly basic salary into a daily rate. The UAE method treats one month as 30 days, so your daily wage is simply basic monthly salary ÷ 30. A basic salary of AED 10,000 gives a daily wage of AED 333.33. This is the MOHRE / u.ae convention and the one this tool uses throughout.
2. The first five years — 21 days a year. For each of your first five years of service you earn 21 days of basic wage. That is 21 × your daily wage per year. At AED 10,000 basic, one full year earns 21 × AED 333.33 = AED 7,000, and a full five years earns 5 × 21 = 105 days, or AED 35,000.
3. Every year after five — 30 days a year. Once you pass five years, each additional year earns 30 days of basic wage — a full month’s basic per year. A worker with ten years of service earns the 105 days from the first five years plus 5 × 30 = 150 days for years six to ten, for 255 days in total. Partial years in this band are pro-rated, so six-and-a-half years earns 30 × 1.5 = 45 days on top of the first-five-year block.
4. The two-year cap. However long you stay, total gratuity cannot exceed two years’ basic wage — that is basic salary × 24 months. For most careers the cap never bites: on AED 10,000 basic it sits at AED 240,000 — 720 days of basic wage, which the 21-then-30-day accrual first reaches after about 25 and a half years of service (105 days for the first five years, then 30 a year: 105 + 30 × 20.5 = 720). But for very long-tenured employees it is a real ceiling, and the calculator applies it automatically. The day-by-day accrual is still shown in full so you can see where the cap starts to limit the raw figure. A note on the statute: Article 51(6) writes the ceiling as two years’ wage, and the law’s definitions distinguish “Basic Wage” (which excludes allowances) from “Wage” (basic plus cash allowances and benefits). Because the accrual itself runs on basic wage under Article 51(2), this calculator applies the narrower, more conservative basic-wage reading — basic × 24 — throughout, and every figure on this page follows it.
Put together, the formula is: gratuity = (21 × daily wage × min(years, 5)) + (30 × daily wage × max(years − 5, 0)), then limited to basic × 24. That is exactly what the calculator computes, and exactly what the tables on this page are built from.
