Country-Specific Calculators

5 calculators built around one country's tax code or mortgage market, where the general-purpose tools would give you the wrong answer.

United States

Federal brackets, FICA withholding and the full PITI picture on a mortgage.

United Kingdom

PAYE, National Insurance and student loan repayments, including the Scottish bands.

European Union

VAT across all 27 member states, with B2B reverse charge and import VAT.

Why these are separate

Most calculators on this site work anywhere — a loan repayment or a compound interest projection follows the same maths in any currency. Tax does not. Brackets, allowances, payroll contributions and VAT rates are written into each country's law, and a generic calculator would quietly give you a number that does not apply.

These tools encode one jurisdiction each. Use them when the question is specifically about US, UK or EU rules, and the general calculators for everything else.
