What is UK Child Benefit Calculator?
▾
UK Child Benefit is a government payment to parents or guardians responsible for bringing up a child under 16 (or under 20 if in approved education or training). From April 2024, the rates are £25.60 per week for the first child and £16.95 per week for each additional child. Child Benefit is usually paid every 4 weeks. The High Income Child Benefit Charge (HICBC) is a clawback mechanism affecting households where either partner has an adjusted net income over £60,000 (from April 2024). For every £200 of income above £60,000, 1% of the Child Benefit received is clawed back through a Self Assessment tax charge. At £80,000 or above, 100% of Child Benefit is clawed back — meaning there is effectively no net financial benefit to claiming it, though claiming is still recommended to protect NI records and build qualifying years. The HICBC threshold was raised from £50,000 to £60,000 in April 2024, helping many families who were previously subject to the charge. The charge applies to the higher earner in the couple, not the person receiving the Child Benefit. Child Benefit must be claimed from HMRC and can be backdated up to 3 months.

Formula
▾
Child Benefit = £25.60/week (1st child) + £16.95/week (each additional child); HICBC = (Child Benefit received / 100) × floor((adjusted net income - 60000) / 200)How to UK Child Benefit Calculator
▾
- 1Determine the total Child Benefit you receive: £25.60/week for child 1, £16.95/week for each additional child
- 2Calculate the annual Child Benefit amount (multiply weekly rate by 52)
- 3Check the adjusted net income of both partners — the HICBC is based on the higher earner's income
- 4If the higher earner's adjusted net income is below £60,000, no HICBC applies and the full benefit is received
- 5If income is between £60,000 and £80,000, the charge equals 1% of benefit per £200 of income over £60,000
- 6If income is £80,000 or above, the charge equals 100% of benefit — the benefit is fully clawed back
- 7Reduce adjusted net income through pension contributions or Gift Aid to reduce or eliminate the HICBC
Worked Examples
▾
(£25.60 + £16.95) × 52 = £2,212.40/year. Income below £60,000 so no charge.
With two children, the total Child Benefit is (£25.60 + £16.95) × 52 = £2,212.40 per year. As neither partner earns above £60,000, the full benefit is retained.
Income £10,000 above £60,000. (10,000 / 200) × 1% = 50% clawback. £1,331.20 × 50% = £665.60 charge.
Income is £10,000 above the threshold. At £200 per 1%, that is 50 units × 1% = 50% clawback. The family keeps only half the Child Benefit.
Income £80,000+ means 100% clawback. Still worth claiming to protect NI credits.
Income above £80,000 triggers full clawback. Although the net financial benefit is zero, claiming Child Benefit still protects the NI record for the non-working parent and ensures automatic Child Benefit NI credits.
£75,000 - £15,000 pension = £60,000 adjusted net income. HICBC threshold not breached.
A £15,000 pension contribution reduces adjusted net income to exactly £60,000, eliminating the HICBC entirely and retaining the full Child Benefit of £1,331.20 per year.

Frequently Asked Questions
▾
Can I opt out of Child Benefit to avoid HICBC?
You can opt out of receiving Child Benefit payments (without giving up the right to the benefit) to avoid the administrative burden of the HICBC. However, you lose the NI credits associated with claiming, so this is generally only sensible if the non-working parent already has a full NI record or is employed.
How does the High Income Child Benefit Charge (HICBC) work?
The HICBC is a tax charge applied if you or your partner has an individual adjusted net income above a certain threshold, even if you are not the one claiming Child Benefit. The charge is equal to 1% of the total Child Benefit received for every £200 of income above £60,000. This means the full amount of Child Benefit is effectively repaid once an individual's adjusted net income reaches £80,000.
What are the income thresholds for the High Income Child Benefit Charge (HICBC)?
From April 6, 2024, the High Income Child Benefit Charge (HICBC) begins when an individual's adjusted net income exceeds £60,000 in a tax year. The charge gradually increases as income rises above this threshold. Child Benefit is fully clawed back, meaning 100% is repaid, once an individual's adjusted net income reaches £80,000.
How is Child Benefit usually paid and can I choose the frequency?
Child Benefit is typically paid every four weeks directly into your bank account. However, single parents or those receiving certain other benefits, such as Income Support, may be able to opt for weekly payments instead. Payments are generally made on a Monday or Tuesday, with specific dates provided by HMRC.
What specific types of education or training qualify a child aged 16-19 for Child Benefit?
For Child Benefit purposes, approved education or training for a child aged 16-19 generally includes full-time non-advanced education, such as A-Levels, NVQ Level 3, or equivalent courses at a school or college. The course must involve at least 12 hours a week of supervised study or tuition. It typically does not include higher education at university or apprenticeships where the child is employed.
Common Mistakes to Avoid
▾
- !Not registering for Self Assessment to pay HICBC, leading to unexpected HMRC penalties for late payment
- !Opting entirely out of Child Benefit without realising the loss of NI credits for the non-working parent
- !Assuming the HICBC applies to combined household income — it applies only to the individual with the higher adjusted net income
- !Forgetting to increase pension contributions before year end to reduce adjusted net income and lower or eliminate the HICBC
- !Not backdating the Child Benefit claim — it can only be backdated 3 months, so delaying means losing money
- !Assuming both partners in a couple with incomes below £60,000 individually are unaffected — if one earns above the threshold the charge still applies
Pro Tip
If your adjusted net income is between £60,000 and £80,000, calculate exactly how much pension contribution would bring you below £60,000. The pension contribution saves both HICBC and income tax, making the effective saving rate for a 40% taxpayer more than 40% on the contribution.
Did you know?
Child Benefit was first introduced in the UK in 1977 as a universal payment — the first truly universal benefit available to all families regardless of income. For its first 35 years there was no means testing. The HICBC was introduced in 2013, marking the end of universal Child Benefit.
