What are these free tools for?
We built these tools for the small jobs that come up every week in a UAE business: working out VAT or end-of-service gratuity, checking whether a domain's email records are set up correctly, formatting JSON, testing colour contrast, or estimating what a website should cost. They are free, need no sign-up, and most run entirely in your browser — what you type never leaves your device.
How accurate are the calculators?
Calculators follow the published UAE rules they are based on (for example the 5% VAT rate and the UAE Labour Law gratuity formula) and show their working so you can check it. They are for estimates and planning; for decisions with legal or tax consequences, confirm the figure with your accountant, HR adviser or the relevant authority. Network tools such as DNS lookup and SSL checks query live public data at the moment you run them.
Frequently asked questions
Are the tools really free?
Yes. There is no sign-up, no limit on use and no paywall.
Do the tools store what I type?
Tools marked “Runs in your browser” never send your input to our servers. Network tools such as DNS or SSL checks send only the domain or URL you enter, to fetch public data.
Which tools are most useful for UAE businesses?
The UAE VAT calculator, gratuity calculator, loan and mortgage calculators, and the SPF/DMARC and DNS checkers for business email.
Can I use the results in official documents?
Use them as estimates. Confirm tax, salary and legal figures with a qualified professional or the relevant authority.
Do the tools work on mobile?
Yes. Every tool is designed for phones first and works offline once loaded, if it runs in the browser.
How often are the calculators updated?
We review them when UAE rules change, and each tool page notes the rules it follows.
Can I embed a tool on my website?
Not yet. Embeddable versions are on our roadmap; link to the tool page in the meantime.
Can you build a custom calculator for my business?
Yes. Branded calculators and quote estimators are a common lead-generation feature on sites we build.
I found a mistake in a tool. What should I do?
Email [email protected] with the tool name and the inputs you used, and we will check it.
How many tools are there?
The number grows every month. Browse by category or use search to find the one you need.
Need something these tools can’t do?
We build custom calculators, portals and automations for UAE businesses.
