Kuwait calls its end-of-service benefit an indemnity, and Article 51 of Law No. 6 of 2010 sets out how it builds. The structure rewards longer service with a higher annual rate, and it applies a separate reduction if you resign.
Here is the formula in plain terms.
For each of your first five years you earn 15 days’ wage; from the sixth year onward you earn a full month’s wage per year. The daily wage is usually the monthly salary divided by 30, though some employers use a 26 working-day basis.
On resignation, the indemnity is scaled by total service: nothing under three years, one-half from three to five years, two-thirds from five to ten years, and the full amount from ten years onward.
On a KWD 800 monthly salary, five years earns about KWD 2,000 (15 days × 5 years), and ten years adds five full months for around KWD 6,000 in total before any resignation reduction.
