What is my net pay after pension UK?
Net pay after pension is your take-home once Income Tax, National Insurance and your pension contribution are deducted. Under net-pay or salary sacrifice arrangements, pension is taken from gross pay so you get full tax relief automatically; under relief-at-source schemes the provider tops up basic-rate relief instead.
Full answer
There are three UK workplace pension methods. Net-pay arrangement: the full pension contribution is deducted from gross salary before PAYE is calculated, giving instant tax relief at your top marginal rate but no NI saving. Relief-at-source: the contribution is taken from net pay, then the provider claims 20% back from HMRC; higher-rate taxpayers must reclaim the extra 20–25% via self-assessment or by writing to HMRC. Salary sacrifice: you contractually give up gross pay in exchange for an employer contribution — saving both tax and NI (8% or 2% employee, 15% employer). Worked example for £50,000 salary with 5% employee pension (£2,500 gross): under relief-at-source you pay £2,000 net, the provider adds £500. Under salary sacrifice the same £2,500 lands in your pension and your taxable salary drops to £47,500, cutting tax by £500 and NI by £200, with the employer also saving £375 NI (often shared). Your final take-home depends on tax code, student loan, region and benefits. The Take-Home Pay calculator lets you toggle pension method and see exact net pay.
