High Income Child Benefit Charge calculator

Earning over £60,000 and getting Child Benefit (or living with someone who does)? Enter your income to estimate your adjusted net income, the charge you'd pay back, and how much a pension or Gift Aid payment could reduce it. Uses the rules for tax years from 2024-25 onwards and current GOV.UK Child Benefit rates.

How this is worked out

Adjusted net income: all your taxable income (salary, profits, rent, savings interest, dividends) before Personal Allowance, minus the grossed-up amount of personal pension payments made with relief at source and Gift Aid donations (the amount you paid × 1.25). Workplace pensions taken from pay before tax and salary sacrifice already lower the salary figure.
Child Benefit: £27.05 a week for the eldest or only child and £17.90 a week for each additional child (current GOV.UK rates). The yearly total is rounded down to whole pounds.
The charge: 1% of the Child Benefit for every full £200 of adjusted net income over £60,000, rounded down to a whole percent, up to 100% at £80,000. The charge itself is rounded down to whole pounds.
Who pays: if both partners are over £60,000, whoever has the higher adjusted net income pays the charge.
