    Where Does Your Salary Actually Go?

    Most people glance at their payslip, note the net figure, and move on. But between your gross salary and the money hitting your bank account, several deductions are silently carved out — and understanding each one is the first step to keeping more of what you earn.

    Income Tax, National Insurance, pension contributions, and student loan repayments each follow their own thresholds and rates. A salary of £50,000 doesn't mean you pay 40% tax on all of it — only the portion above £50,270 enters the Higher Rate band. Meanwhile, NI drops from 8% to 2% at the same threshold, which confuses many people into thinking they're being overtaxed.

    This calculator pulls together every deduction in one place, shows you exactly what your employer pays on top, and highlights opportunities to reduce your tax bill through pension contributions, salary sacrifice, and other reliefs. If you're considering a pay rise, it also shows how much of the increase you'll actually keep.
