Payslip explanation

Read your payslip in plain English

This section turns common payslip lines into short explanations that are easier to scan, understand, and remember.

Gross Pay

£40,000

Gross pay is your total salary before tax, National Insurance, pension, and other deductions are taken off.

Why it matters: This is the headline salary number, but it is not the amount you actually receive in your bank account.

PAYE / Income Tax

£5,486

PAYE is the system employers use to collect Income Tax from your salary automatically before you are paid.

Why it matters: If this number feels too high or too low, your tax code or income setup may need checking.

National Insurance

£2,194

National Insurance is deducted from earnings above a threshold and helps fund certain state benefits and services.

Why it matters: Many employees focus only on tax, but NI can also take a noticeable amount from pay.

Pension

£2,000

Pension contributions are amounts taken from your pay to support retirement savings through your workplace scheme.

Why it matters: This reduces your immediate take-home pay, but contributes to long-term financial planning.

Student Loan

£1,038

Student loan repayments are deducted automatically once your income goes above the threshold for your loan plan.

Why it matters: This is often one of the biggest reasons a payslip feels lower than expected for graduates.

Tax Code

1257L

Your tax code helps determine how much tax-free income you can receive and how PAYE is applied to your salary.

Why it matters: A tax code can strongly affect your deductions, especially if it is unusual, temporary, or assigned incorrectly.

Net Pay

£29,282

Net pay is what remains after deductions. This is the money you actually keep.

Why it matters: This is the most useful number for budgeting, comparing job offers, and understanding real earnings.

Tax code insight

Looks normal

Standard UK tax code

Tax code entered: 1257L

Quick reading

1257L is the most common tax code and usually means you are receiving the standard Personal Allowance.

More detail

This normally means you can earn the usual tax-free allowance before Income Tax starts being deducted. For many employees, this is the expected code.
