What is the Income Tax Calculator?
People comparing jobs at home and abroad want to know what they will actually take home. The income tax calculator estimates tax for Pakistan (salaried slabs), the UK (income tax and National Insurance, England), the UAE and Saudi Arabia (no personal income tax on salaries).
You can also enter custom slabs to model another country or a proposed budget. For a detailed Pakistani salary breakdown, use the FBR Salary Tax Calculator 2026-27; to convert foreign pay to rupees, use the International Salary Calculator.
How to use the Income Tax Calculator
- Choose a country or Custom slabs.
- Enter your income and whether it is monthly or yearly.
- For the UK, choose whether to include National Insurance.
- Read yearly tax, monthly tax, take-home pay and effective rate.
Formula
Progressive tax = sum of (income in each band × that band's rate)
Example
A UK salary of £45,000 pays about £6,486 income tax and £2,594 National Insurance, leaving about £35,920 a year. A Pakistani salary of Rs 200,000 a month pays about Rs 13,000 tax a month under FY 2026-27 slabs.
Marginal vs effective tax rate
Your marginal rate is the rate on your last rupee or pound of income. Your effective rate is total tax divided by total income, which is always lower in a progressive system. A pay rise that moves you into a higher band only taxes the extra amount at the higher rate.
