If you live in Scotland

A Scottish taxpayer on £20,000 pays £1,446 Income Tax, £40 less than someone in England. Take-home is £1,497 a month. See the Scottish tax calculator for band details.

With pension contributions

Paying 5% (£1,000) into a net pay workplace pension reduces take-home to £1,427 a month, only £67 less, because the contribution comes out before tax. Through salary sacrifice at 8% (£1,600 a year), take-home would be £1,397 a month, as you'd also save National Insurance.

Assumptions

Tax year 2026/27 (6 April 2026 to 5 April 2027). Standard Personal Allowance with taper above £100,000, category A NI, one job, paid evenly across the year, 37.5 hours a week for hourly figures, 260 working days. Employer pension contributions and benefits aren't included. Annual NI and loan estimates can differ from payroll rounding.

A budget comparison at £20,000

The baseline monthly estimate is £1,493, compared with £1,427 in the 5% net pay pension example above. That difference is money redirected towards a pension rather than available for current spending; the two figures describe different arrangements, not competing answers to the same question.

The move from £20,000 to £25,000 adds an estimated £300 a month on the baseline assumptions. Compare that increment with any new regular costs of the role, instead of budgeting from the gross rise alone.
