Employer on-costs across these four markets are not the same charge at different rates. They are different charges entirely — and the shape of the bill changes what a cheap hire even means.
Employer on-costs run about 22% in the US, 16% in the UK, 10% in Saudi Arabia and 7% in the UAE — but they fund completely different things. The US number is mostly the employer health premium nobody else pays. The UK number is almost all employer National Insurance at 15% above a £5,000 threshold. The Gulf charges no payroll tax on expatriates at all, and bills you instead through gratuity accrual, labour levies and the visa cycle.
The counter-intuitive one is Saudi Arabia, where the flat expatriate levy and proportional GOSI cross at about SAR 145,000. Below that — where most SDR packages sit — a Saudi national is the cheaper hire.

Percentages are computed live from the same dataset each calculator uses, at each market's starting salary. Change the salary on any calculator and the percentage moves — the Gulf figures in particular are sensitive to it, because flat charges weigh more on lower pay.
Each figure is a statutory floor: the employer contributions, accruals and government fees you cannot avoid, built from primary sources — HMRC and The Pensions Regulator for the UK, IRS, KFF and BLS for the US, UAE Federal Decree-Law 33 of 2021 for the Emirates, and the GOSI schedule with the Ministry of Human Resources levy tables for Saudi Arabia.
They exclude tooling, data, recruitment, onboarding and management overhead, all of which are real and all of which push the number up. They also exclude ramp and attrition from the headline, though each calculator lets you price them in — roughly three months to productivity and 40% annual attrition, which together mean a rep-year buys about nine productive months.
Two of these four markets have no salary benchmark we are willing to publish. For the UAE the only public figure we found rests on five self-reported salaries; for Saudi Arabia the public aggregators are visibly broken on this role, and the regional guides that would settle it are gated. Saying so is more useful than filling the gap with a number that would describe nobody.
