Your pay
Tax code Standard
Leave blank for the standard Personal Allowance, reduced automatically above £100,000. Codes such as K500, BR, D0, 0T and NT work, as do the S and C prefixes.
Student loan None
Pension None
Your percentage applies to qualifying earnings only: pay between the lower and upper limits, including overtime and bonus. The contribution gets tax relief but not National Insurance relief.
Bonus and pay frequency Monthly
A bonus is paid in one pay period. The results compare that period with a normal one.
Overtime None
Your hourly rate is taken as salary ÷ weeks in a year ÷ normal hours a week.
Childcare vouchers and salary sacrifice None
Most benefits swapped for salary since April 2017 are taxed on the pay given up, so they save National Insurance only. Cycle to work schemes and electric cars still save both. Leave pension out: it has its own section.
Benefits and allowances None
Benefits such as a company car or medical cover are taxed but carry no employee's National Insurance. Leave them out if your tax code already collects the tax. Cash allowances are paid with your salary and taxed like it.

How your tax code sets your income tax
The number in your tax code is your tax-free pay for the year divided by ten, so 1257L means £12,570. Payroll spreads that allowance across your pay periods and taxes the rest at the basic, higher and additional rates. A K code adds to your taxable pay instead, BR, D0 and D1 tax everything at one rate, and an S or C prefix applies the Scottish or Welsh rates. Leave the code blank and the calculator uses the standard allowance, which shrinks by £1 for every £2 of income over £100,000.
Pension contributions and tax relief
An auto-enrolment percentage applies only to qualifying earnings, the band of pay between a lower and an upper limit, not to your whole salary. Contributions taken before tax save income tax at your top rate. Under salary sacrifice you give up the pay altogether, so you save National Insurance as well. With a personal pension you pay from your take-home pay and the provider adds basic rate relief.
Student loan repayments
Plans 1, 2, 4 and 5 are repaid at 9% of pay above the plan's threshold, and a postgraduate loan at 6% above its own threshold on top. Deductions are worked out each pay period and rounded down to the pound. If you have more than one undergraduate plan, a single 9% is taken above the lowest threshold and shared between them.
Bonuses, overtime and salary sacrifice
A bonus is taxed in the pay period it is paid, so that payslip carries more tax and National Insurance than usual, though the year's income tax comes out the same. Overtime is valued from your hourly rate. Salary sacrifice for most benefits now saves National Insurance only, but cycle to work schemes, electric cars and childcare vouchers for existing members still save tax too.
