The calculators elsewhere in this section mostly assume a number you already know — take-home pay, in particular, feeds directly into the affordability and savings-rate figures used across the loan, mortgage and savings calculators above. This subsection is where that number gets worked out in the first place: what a given salary and tax code actually leave after deductions, rather than the headline figure on an offer letter or payslip before anything has been taken off.
Calculators in this section
Deductions rarely stop at income tax. Depending on where you are, a salary can also carry social insurance, a pension contribution, a student loan repayment or a local tax — each calculated on a different slice of income and often in a different order, which is why two people on the same gross salary can end up with noticeably different net pay. Working through them in the right sequence is what separates an accurate take-home figure from a rough guess.
This is a narrower, personal-finance-focused counterpart to the standalone tax calculators covering income tax and VAT rules by country — the calculators here start from a salary and work out what actually lands in the bank each month, rather than working through a full national tax system.
