£101,000 salary: £1,000 over, and what it costs

On £101,000 you take home £68,937 a year (£5,745 a month). Being £1,000 over £100,000 costs £10,550 a year of childcare support with one child under 3. £1,000 of salary sacrifice (£83 a month) models restoring that support, subject to childcare eligibility and timing.

Scenarios at £101,000

Children under 5, a buffer under the line, and what a rise from here is worth.

Cash is take-home plus Child Benefit less the charge. For the example children aged 9 months to 2, childcare support is £0 while adjusted net income is over £100,000; the sacrifice brings it back, and the pension money stays yours.

A buffer covers income you can't control before 5 April: a bonus, savings interest, a benefit in kind. Through a personal pension instead, pay in 80% of the sacrifice and the provider grosses it up.

Questions at £101,000

How much is £101,000 after tax?
£68,937 a year, or £5,745 a month: £28,032 of income tax and £4,031 of National Insurance. That assumes no pension contributions, no student loan and England, Wales or Northern Ireland rules for 2026-27.
How much do I need to sacrifice to get under £100k on £101,000?
£1,000 a year (£83 a month) through salary sacrifice. Through a personal pension instead, you'd pay in £800 and the provider adds basic-rate relief to make £1,000.
Can I sacrifice part of my bonus instead?
Often, yes, if your employer's scheme allows it and you agree it before the bonus is paid. £1,000 of bonus into your pension does the same job as £83 a month from salary. Once a bonus has been paid, a personal pension contribution before 5 April is the fallback.
Is it worth it?
For the modelled younger children, the comparison is: £1,000 of sacrifice costs £380 of take-home and keeps £10,550 of childcare support with one child. Without children it's a small pension contribution with 62% relief.

Assumptions

One earner, England, Wales or Northern Ireland rules for 2026-27, salary only, no pension and no student loan. Childcare figures assume each child is 9 months to 2 years old and in nursery enough to use the full Tax-Free Childcare top-up; funded hours are valued at £7.50 an hour. These are England childcare scenarios assuming all other eligibility conditions are met. Children with universal 15 hours retain those hours above £100,000; use the calculator to include them.
