How to use this calculator
- 1
Enter the number of eligible children under 16 (or under 20 if in approved education or training).
- 2
Enter the adjusted net income of the higher earner in the household — this is gross income minus pension contributions and gift aid donations.
- 3
At or below £60,000 of adjusted net income there is no charge; between £60,000 and £80,000 the charge rises by 1% of the benefit for each full £200; at £80,000 and above all of it is charged.
- 4
Enter the figure you have already adjusted for pension contributions and Gift Aid — the tool does not make those adjustments for you.
- 5
The results show gross benefit, the charge, the net amount and the weekly rates the tool uses.
Frequently asked questions
How does this tool calculate Child Benefit?
This tool uses a weekly rate for the first child plus a weekly rate for each additional child, multiplied by 52. The figures built into it carry a 2024/25 label: £25.60 for the first child and £16.95 for each additional child. Two children therefore give £42.55 a week and £2,213 a year after rounding. Ages, eligibility, and the eldest-child rule are not checked; you simply enter a count.
How is the High Income Child Benefit Charge worked out?
The charge is nil up to £60,000 of adjusted net income. Above that, the tool takes the excess, divides it by £200, rounds down to a whole number and treats that as the percentage of annual benefit to claw back, capped at 100%. At £62,000 that is 10%, at £70,000 it is 50% and at £80,000 or more it is 100%. The thresholds and the 1% per £200 step are the figures built into this tool.
Whose income should I enter?
The box is labelled for the highest earner’s adjusted net income, and the tool uses exactly the number you type. It does not subtract pension contributions or Gift Aid donations for you, and it does not combine two incomes. If one partner’s adjusted net income is £58,000 and the other’s is £65,000, the figure to enter is £65,000.
Why does a £1 difference in income sometimes change nothing?
Because the charge moves in £200 steps. An income of £60,199 gives a 0% charge, while £60,200 gives 1%. For two children, 1% is about £22 of the £2,213 annual benefit. Inside a step the tool does not interpolate, so the charge jumps instead of rising smoothly.
What is the difference between gross and net Child Benefit in the results?
Gross is the benefit before any charge, calculated from the weekly rates. Net is gross minus the charge amount. The tool simply subtracts the charge from the gross figure; how and when a charge is collected is not modelled.
What does it do with zero children or odd numbers?
A count of zero (which is also what a cleared box becomes) returns £0 and a note asking you to enter children. A decimal is rounded to the nearest whole number. A negative count is treated as zero. Income of zero (a cleared box counts as 0) or below is treated as zero for the charge calculation.
Is the rate and threshold current?
The figures are the ones labelled 2024/25 in the tool. UK rates and thresholds change at least every tax year on 6 April, the tool’s tables are not updated automatically, and HMRC governs what applies to you. A different tax year may have different weekly amounts or a different income threshold, so check before relying on the output.
What does the tool not cover?
It does not model payment calendars other than 52 weeks, Guardian’s Allowance, benefits for children over 16, who may claim, how the charge interacts with other tax on the same return, or opting out of payments. It also gives no advice on whether to claim.
UK Child Benefit and the income charge: how this calculator works it out
How the benefit is built
The tool starts with a weekly amount for the first child and a lower weekly amount for each additional child, then multiplies by 52 weeks. The built-in figures carry a 2024/25 label: £25.60 and £16.95. One child comes to £1,331 a year after rounding, two children to £2,213 and three to £3,094. The children box is rounded to a whole number, and zero returns a short note instead of a table of figures. Nothing about the child’s age or education status is checked.
How the high income charge is applied
You enter the adjusted net income of the higher earner. Up to £60,000 there is no charge. Above that the tool divides the amount over £60,000 by £200, rounds down, and takes that whole number as a percentage of the annual benefit; from £80,000 the whole amount is charged. Because it rounds down, each step is a £200 band, so £62,000 is 10% and £62,199 is also 10%. The charge is shown as an amount, the net benefit is gross minus the charge, and the percentage is displayed separately.
Worked example: two children at £62,000 and £70,000
For two children the gross benefit is £2,213. At £62,000 the excess is £2,000, which is ten steps, so the charge is 10% or £221 and the net benefit is £1,991. At £70,000 the excess is £10,000, fifty steps, so the charge is 50% or £1,106 and the net benefit is £1,106. With one child at £70,000, gross is £1,331 and the 50% charge is £666, leaving £666. With three children at £70,000, gross is £3,094 and the charge is £1,547.
Charge across the band
The table shows the charge for a two-child family as income climbs from the threshold to the point where the whole benefit is charged. It is the fastest way to see that the amount rises in equal steps, with each £200 of income adding the same sum, about £22 for two children.
| Adjusted net income | Charge rate | Charge | Net benefit |
|---|---|---|---|
| £60,000 | 0% | £0 | £2,213 |
| £62,000 | 10% | £221 | £1,991 |
| £70,000 | 50% | £1,106 | £1,106 |
| £75,000 | 75% | £1,659 | £553 |
| £80,000 | 100% | £2,213 | £0 |
What the figures do not include
The tool shows only the benefit and the charge. It does not total your Self Assessment, work out adjusted net income from salary, pensions or donations, or deal with the dates on which a charge is paid. Because the rates and the £60,000 and £80,000 points are built into the tool and not looked up by year, a different tax year can give different results. Use it to compare scenarios, and check HMRC for the amounts that apply.
