Estimate UK take-home pay for £400 a week, equivalent to about £20,800 gross a year before deductions.
What £20,800 actually leaves you with
£400 a week works out at about £20,800 gross a year. The annual figure is the one the deductions are set against, because the Personal Allowance and the Income Tax bands are annual amounts, so what lands each week follows from the yearly total rather than from that week's pay on its own.
Of £20,800.00 gross a year: Income Tax £1,646.00, National Insurance £658.40, Take-home £18,495.60.

How to interpret this £20,800 example
basic-budget estimate
This salary range is often used for rent, bills and weekly-pay comparisons, so the monthly take-home figure is usually more useful than the gross headline. £20,800 is the annual gross employment pay before deductions. The calculation table shows how that becomes about £1,541 a month and £18,496 a year after the listed deductions.
This page is the twenty thousand eight hundred pounds annual gross salary case.
A nearby lower comparison would be twenty thousand seven hundred pounds annual gross salary.
A nearby higher comparison would be twenty thousand nine hundred pounds annual gross salary.
Review pension and student-loan settings first because they can be a visible share of the monthly difference.
Add pension contributions if the real job has an employee pension deduction.
Switch region only if the tax residence assumption differs from the default England, Wales and Northern Ireland model.
Select a student-loan plan if repayments should be included.
Student-loan and payroll focus
The £18,496 annual take-home estimate assumes the selected student-loan settings. Payroll can still differ if a loan starts or stops, a bonus lands, or records change part-way through the tax year.
Match the loan plan and postgraduate-loan setting before comparing with a payslip.
Do not treat a one-month payroll difference as an error without checking timing and year-to-date figures.
£20,800 sits £8,230 above the Personal Allowance and £29,470 below the £50,270 higher-rate threshold, so the whole of the taxed portion is charged at the basic rate.
A £1,000 pay rise from £20,800 would add about £720 to annual take-home pay — roughly 72p in the pound, or £60 a month. That is the figure worth comparing against any extra hours, travel or responsibility the rise comes with.
Per hour, £20,800 works out at roughly £10.67 gross on a 37.5-hour week. The National Living Wage for people aged 21 and over is £12.71 an hour, or about £24,785 a year at the same hours, so this salary is around 0.8 times full-time minimum-wage pay.
A Scottish taxpayer on £20,800 would take home about £18,535 a year, £40 more than the £18,496 shown here, because Scotland sets its own Income Tax bands. National Insurance is the same across the UK.

What changes this result
What changes this result
Student loan threshold
At £20,800 the plan matters: Plan 5 starts at £25,000 and Plan 2 at £29,385, so this salary is £4,200 below the Plan 5 threshold and £8,585 below Plan 2.
Universal Credit taper
If you claim Universal Credit, earnings above the work allowance reduce the award by 55p in the pound, which changes the real value of a pay rise at this level far more than tax does.
Pension contribution
Changing the rate or method can change taxable income, National Insurance and take-home pay.
Tax code and region
Scottish Income Tax, Welsh codes, emergency tax or a non-standard tax code can move the result.
Useful comparisons
Useful comparisons
£19,800 comparison
Dropping to £19,800 removes £1,000 of gross pay, but less than that from take-home once the tax and National Insurance on that slice come off.
£21,800 comparison
Rising to £21,800 adds £1,000 gross. How much of it survives depends on which band that £1,000 falls into, which is the whole point of checking before accepting a rise.
5% pension comparison
Compare the same gross salary with and without a 5% pension setting before budgeting.
