How we calculate take-home pay across 100 countries
Every country page on GlobalTax answers the same simple question: if you earn X gross, what actually lands in your bank account? Across 100 different tax systems, the answer is rarely one number — it's a chain of calculations that depend on residency, allowances, social contributions and a handful of country quirks. Here is how we get from a gross salary to a credible take-home figure, and where we deliberately stop short.
Start with statutory brackets
Every calculator begins with the latest published progressive brackets for the relevant tax year — usually the one that the country's tax authority has officially gazetted. Income inside each bracket is taxed at that bracket's marginal rate, then summed. This sounds obvious, but a surprising number of online calculators apply the top marginal rate to the whole salary, which dramatically overstates the tax bill. We don't. The per-bracket breakdown you see on the result page is the actual math the calculator did, exposed for you to audit.
Layer on social contributions
In most of Europe and Latin America, employee-side social contributions are the bigger line item — pension, health, unemployment, family solidarity, and a long tail of fund-specific levies. We compute these on top of income tax with country-specific caps, floors and exemption thresholds (for example, France's PASS ceiling or Mexico's IMSS UMAs). Where the employer share is enormous but invisible to the employee, we note it but don't subtract it: take-home is about what you see on your payslip.
Apply the obvious allowances
Standard deductions, personal allowances and the most common credits are applied automatically — the UK personal allowance with the £100k taper, Germany's Grundfreibetrag, India's standard deduction under the new regime, and so on. We deliberately don't try to model every niche relief (mortgage interest, donations, dependents in some jurisdictions). Specialised reliefs are flagged as out of scope on the country page so you know what to add yourself.
Translate everything into USD
Every figure is annotated with an approximate USD equivalent at indicative mid-market rates so you can compare €60,000 in France with ₹60,00,000 in India on equal footing. The USD conversion is not what your bank will give you — it's a yardstick. Combine it with our budget planner if you want to see whether the take-home actually supports the lifestyle you'd lead in that country.
What we don't do (yet)
We don't model corporate stock vesting across borders, complex non-resident schedules outside the headline rate, wealth taxes, or property and inheritance taxes. We also don't pretend the rates we publish are advice — they're a fast, honest estimate. For anything you'd sign your name to, talk to a qualified professional in the country you're filing in.
