The trick to calculating Oman gratuity under Royal Decree 53/2023 is to split your service at August 2023 and value each part with its own rule. Here is the method in four steps, with worked figures.

Step 1 — Take your basic salary

Oman gratuity is based on basic salary only. Use your basic monthly figure throughout — allowances are excluded.

Step 2 — Split your service at August 2023

Work out how many years of service fell before August 2023 (old law) and how many fell from August 2023 onward (new law). Our Oman gratuity calculator asks for exactly this split.

Step 3 — Value the old-law portion

For pre-August-2023 service, the old formula applies: 15 days per year for the first three years, then one month per year after. A day is basic ÷ 30. For 2 pre-2023 years on OMR 600: 2 × 15 × (600 ÷ 30) = OMR 600.

Step 4 — Value the new-law portion and add

For service from August 2023, apply one month of basic per year. For 3 new-law years on OMR 600: 3 × 600 = OMR 1,800. Add the two portions together:

More worked scenarios (OMR 600 basic)

Notice the 4-year all-old-law row: the first three years earn 15 days each (3 × 15 × 20 = OMR 900) and the fourth year earns a full month (OMR 600), totalling OMR 1,500. Run your exact split on the Oman gratuity calculator; the rule is on the Oman gratuity guide.

Common pitfalls

Two traps: using gross instead of basic salary (gratuity is basic-only), and forgetting the one-year minimum service. For more, see the Oman gratuity FAQ and the complete gratuity guide. Don't forget to add your leave encashment and any notice pay to get your full settlement.

Thinking in "months of basic"

A quick way to sense-check any Oman gratuity is to convert each portion into months of basic salary. The new-law rate is one month per year, so three post-2023 years = 3 months of basic. The old-law rate for the first three years is 15 days each = half a month each = 1.5 months for three years. Add them and multiply by basic. This mental shortcut makes it easy to catch errors before you trust a settlement figure.

Edge case: all service before August 2023

If your entire service predates the reform, only the old formula applies: 15 days per year for the first three years, then one month per year after. So four fully pre-2023 years = 3 × 15 days + 1 month = 1.5 months + 1 month = 2.5 months of basic. On OMR 600 that is OMR 1,500, matching the table above. This case is common for workers who left shortly after the changeover.

Edge case: all service after August 2023

If all your service is post-reform, the sum is pleasingly simple: one month of basic per year. Three years = 3 months = OMR 1,800 on a OMR 600 basic. There is no 15-day early-years discount for new-law service, which is precisely what makes the 2023 rate more generous than the old one.

Verifying an employer's figure

To check a settlement, split your service at August 2023, value each portion in months of basic, sum them, and multiply by your basic salary. Compare with the Oman gratuity calculator. If the numbers differ, the usual causes are using gross instead of basic, misplacing the August-2023 split, or applying the new rate to the first three old-law years.

Key numbers at a glance

Glossary

Royal Decree 53/2023 — Oman's new Labour Law, which raised the gratuity rate for service from August 2023. Basic salary — the base pay figure used for gratuity, excluding allowances. The split — dividing your service into pre- and post-August-2023 portions, each valued by its own rate. Day of basic — basic ÷ 30, used for the 15-day old-law portions.

The bottom line

Convert each portion to months of basic, sum, and multiply by your basic salary. Watch the two traps: gross instead of basic, and applying the new rate to the first three old-law years. The calculator gives you a clean reference figure.

Before you calculate

The worked examples above use tidy round numbers. To apply the method to your real figures, make sure you have the right inputs to hand.

What you'll need to run the numbers

For an Oman gratuity calculation you need your basic salary (not gross), your total service, and the number of years that fell before August 2023. That split is the single most important input, because pre- and post-August-2023 service are valued differently. Your contract and salary certificate provide the basic figure and the dates.

When to get professional advice

Consider advice where the exact date of your changeover service is disputed, where a package is heavily weighted to allowances (only basic counts), or where continuity of service across related employers is unclear. For most workers, splitting the service and running it through the calculator produces a clean, defensible figure.

Frequently asked questions

How do I calculate Oman gratuity across the 2023 change?

Split your service at August 2023: value pre-2023 years with the old formula (15 days/year for the first three, then one month/year) and value later years at one month of basic per year, then add the two together.

What is the gratuity for 5 years at OMR 600 with 2 years before August 2023?

OMR 2,400 — OMR 600 for the two old-law years (2 × 15 × 20) plus OMR 1,800 for the three new-law years (3 × 600).

Is a day of basic salary one thirtieth of the monthly basic?

Yes. For the 15-day portions, a day is basic ÷ 30, so OMR 600 basic gives a daily rate of OMR 20.

Do I need a full year of service before any gratuity is due in Oman?

Yes — the minimum is one year of continuous service.
