Five free calculators for the figures Gulf payroll and finance teams check most often: UAE end of service gratuity, the Saudi end of service award, GOSI contributions, UAE VAT and UAE corporate tax. Each one runs entirely in your browser, shows its working, names the rule it applies and links to the official source, so you can check a settlement, a pay run or an invoice in under a minute.

Three things to know before you rely on a number from any of them.
The figures you type stay on your device. Nothing is sent to a server, nothing is stored, and there is no account or sign-up.
Each calculator applies the published rule as it stood on the date shown and prints its working. Your contract, your free zone, an amendment after that date or the authority's own reading of a case can change the result. None of them is an official tool of MOHRE, HRSD, GOSI, the Federal Tax Authority or the Ministry of Finance, and none is legal or tax advice. Confirm a settlement or a filing with the authority or your adviser before you pay or submit.
Every page names the article or decision it relies on and links to the authority's own text, so you can read the rule yourself rather than take the calculator's word for it.
The calculators answer one question at a time. The People and Finance boxes apply the same rules to every employee and every invoice, month after month.
The People box accrues end of service gratuity month by month, works out GOSI for each employee and generates the WPS SIF file for every pay run. You review the figures; submitting the file to the bank and the authorities stays with you.
See the People boxThe Finance box applies VAT per country at the right rate on every invoice line and assembles the return from live transactions, so the figure you file is the figure you invoiced.
See the Finance boxTurn on the box you need. Pricing never depends on seat count, so the whole payroll or finance team can work in it from day one, in Arabic or English.
See pricingEach one is published once the rule set behind it has been checked against the authority's text. No dates, on purpose.
The longer reads behind each rule set: what changed, who it applies to and what to do about it.
