Why this exists
Most salary-tax calculators cover a single country, hide behind sign-ups, or quietly ignore the social contributions that come off your payslip. If you're weighing a move abroad, what you really want is simple: enter one salary and see, side by side, what you'd actually keep in each place. That's the whole point of Keep the Most — a clear, honest, cross-border comparison across 40+ countries, US states and the Gulf.
What it is — and isn't
It's free, needs no account, and models income tax plus mandatory employee social contributions (FICA, National Insurance, CPP/EI, and the rest) for a single, resident, employed person. It is an estimate to help you compare and plan — not tax advice, and not a filing tool. For the full scope, assumptions and the caveats we're upfront about, see the methodology & sources.
How the numbers are made
Every figure is computed by a transparent, data-driven engine: each country is taxed in its own currency using its published brackets and contribution rates, then converted so you can compare like for like. The tax tables are researched from official revenue authorities, checked against official calculators, and refreshed as rates change. The methodology page lists the primary source for every region.
Who's behind it
Keep the Most is researched and maintained by Rogan Burns. "I kept asking myself where I'd genuinely keep the most of my salary, and couldn't find a tool that answered it cleanly across countries — so I built one. I gather the tax tables, build the models, and check them against official calculators before anything goes live. If you spot a figure that looks off, I want to know — accuracy is the whole point."
