Net pay vs gross pay
Net pay is the answer to "how much actually hit my bank account." Gross pay is the answer to "what's the headline number on my contract." The difference between them is everything your payroll system deducted before paying you.
For a typical UK employee on £50,000 in 2026/27 with the standard 1257L tax code, no pension contribution and no student loan:
- Gross pay: £50,000 annually (£4,167 monthly)
- Income Tax: £7,486 annually (£624 monthly)
- National Insurance: £2,994 annually (£250 monthly)
- Net pay: £39,520 annually (£3,293 monthly)
That's a 21% combined tax-and-NI rate. Add pension contributions or a student loan and net pay drops further.
What gets deducted from gross to reach net
The standard deductions on a UK payslip:
- Income Tax under PAYE
- Employee National Insurance (Class 1)
- Pension contributions (if you're enrolled and not opted out)
- Student loan repayments (if you're on any plan above the threshold)
- Court orders (attachment of earnings, child maintenance)
- Salary sacrifice items (EV lease, cycle-to-work scheme)
- GAYE / payroll giving (charitable donations)
Some of these reduce taxable pay before Income Tax is calculated (salary sacrifice, net pay arrangement pensions, GAYE) while others are deducted from net pay directly (relief-at-source pensions, court orders).
"Net pay arrangement" vs net pay
Confusingly, the same word appears in two unrelated places:
- Net pay (this entry) — your take-home after all deductions
- Net pay arrangement — a specific type of occupational pension where the contribution comes off gross before Income Tax (but after NI)
These are different things. The "net pay arrangement" pension method is named that way because the contribution is deducted before tax — effectively giving you tax relief by reducing taxable pay. Despite the name, it's about how the pension contribution is treated, not about your overall net pay.
When net pay varies month to month
Even on a steady salary, your net pay can change. Common causes include bonus months, tax code updates, statutory pay (SSP, SMP), salary sacrifice changes, student loan threshold updates, and benefits in kind appearing on your code. For the full list, see How to read a UK payslip.
