About the UK Child Benefit Calculator
This UK Child Benefit calculator shows how much Child Benefit your family can get in the 2026/27 tax year and how much of it you keep after the High Income Child Benefit Charge (HICBC). Enter the number of children you are responsible for and the adjusted net income of the higher earner in your household, and you get the weekly rate, the usual four-weekly payment, the yearly total and the net amount after tax.
From 6 April 2026 Child Benefit is £27.05 a week for the eldest or only child and £17.90 a week for each additional child. There is no limit on the number of children. Child Benefit is paid for children under 16, or under 20 if they stay in approved education or training.
The HICBC applies when either partner’s adjusted net income is over £60,000: 1% of the benefit is repaid for every £200 above that, so it is fully repaid at £80,000. Even if you would repay everything, claiming can still be worth it — it protects National Insurance credits for a non-working parent and makes sure your child gets a National Insurance number automatically.
With the default inputs, the child benefit per week is £44.95. Change any value above to recalculate instantly.

Formula and method
Child Benefit is a flat weekly amount: £27.05 for the eldest or only child and £17.90 for each other child in 2026/27. It is normally paid every four weeks (4 × the weekly rate); the yearly figure here uses 52 weeks.
The High Income Child Benefit Charge is based on the adjusted net income (ANI) of the higher-earning partner. For every full £200 of ANI above £60,000, 1% of the year’s Child Benefit is repaid as income tax, reaching 100% at £80,000.

Worked examples
Two children, income £50,000
£27.05 for the eldest plus £17.90 for the second is £44.95 a week, £179.80 every four weeks and £2,337.40 a year. Income is below £60,000, so there is no charge.
Three children, income £70,000
Three children get £62.85 a week, or £3,268.20 a year. Income is £10,000 over £60,000, so 50% is repaid: £1,634.10, leaving £1,634.10.
One child, income £85,000
One child gets £1,406.60 a year. Above £80,000 the charge is 100% of the benefit, so the whole £1,406.60 is repaid through the tax system and nothing is kept.
Frequently asked questions
How much is Child Benefit in 2026/27?+
From 6 April 2026 Child Benefit is £27.05 a week for the eldest or only child and £17.90 a week for each additional child. For two children that is £44.95 a week, or about £2,337 a year.
Is there a limit on how many children I can claim for?+
No. Unlike the old two-child limit in Universal Credit, Child Benefit has always been paid for every child you are responsible for, at £17.90 a week for each child after the first.
When does the High Income Child Benefit Charge apply?+
If you or your partner have adjusted net income over £60,000, the higher earner repays 1% of the Child Benefit for every £200 over that threshold. At £80,000 or more the whole amount is repaid.
Should I claim if I earn over £80,000?+
Usually yes. Claiming gives a non-working or low-earning parent National Insurance credits toward the State Pension and gets your child a National Insurance number. You can opt out of the payments to avoid the charge.
Until what age is Child Benefit paid?+
Until the child turns 16, or until 20 if they stay in approved education (such as A levels or Scottish Highers) or approved training. It is not paid for university study or most apprenticeships.
How is Child Benefit paid?+
Normally every four weeks into a bank account, usually on a Monday or Tuesday. Single parents and families on certain benefits can ask to be paid weekly.
