The Cost of Raising a Child in the UK

The figure quoted in most UK headlines is a quarter of a million pounds, and it is broadly right — but it is measuring something more specific than people assume, and the number that matters to your household is probably not the one in the headline.

What the headline number actually measures

These figures come from the Child Poverty Action Group's annual Cost of a Child work, which is built on the Minimum Income Standard — research by Loughborough University's Centre for Research in Social Policy for the Joseph Rowntree Foundation.

The distinction that matters: the Minimum Income Standard is not a measure of what families do spend. It is a costed basket of what members of the public, in detailed deliberative groups, agree a household needs for a decent standard of living — not survival, and not comfort. So it is a normative figure, not an average of receipts, and it should be read as "what it takes to do this properly" rather than "what it costs people like you".

The numbers

Cost to age 18	Couple	Lone parent
Including rent, childcare and council tax	~£250,000	~£290,000
Basic cost, excluding those three	£167,679	£189,053
Roughly per year, basic	~£9,300	~£10,500

Two things are worth noticing. The gap between the two columns — rent, childcare and council tax — is close to £83,000, which is to say housing and childcare are not a detail of the cost of a child, they are roughly a third of it.

And a lone parent faces a materially higher figure for the same child. That is not a judgement about anything; it is arithmetic. There is no second adult to share the fixed costs of running a household, and childcare is far harder to cover informally when there is only one of you.

Where the money actually goes, by age

The total is not spread evenly, and knowing the shape of it is more useful for planning than the headline.

• 0–4 is the expensive stretch, and almost entirely because of childcare. This is the period where one parent's income is most likely to be reduced or lost, which compounds the cost.
• 5–10 is the cheapest. School absorbs the day, childcare drops to wraparound and holidays, and the child is not yet expensive to feed or clothe.
• 11–18 climbs again — food, clothing, phones, travel, activities and the costs attached to exams and sixth form.

The practical consequence is that the hardest year financially is usually the one immediately after parental leave ends, when childcare starts at full cost and savings have already been drawn down by the leave itself.

What comes off the total

Child Benefit

For 2026-27, Child Benefit is £27.05 a week for the eldest child and £17.90 a week for each additional child. Across 18 years the eldest child alone is worth roughly £25,000 — genuinely material against a £250,000 total.

The High Income Child Benefit Charge begins once the higher earner's adjusted net income passes £60,000, claws back 1% for every £200 above that, and removes the entire award at £80,000. Note that it is assessed on the higher individual earner, not household income, so a couple earning £55,000 each keeps the lot while a single earner on £85,000 keeps none.

Funded childcare and Tax-Free Childcare

Funded hours are the single largest offset during the expensive years, but the headline is term-time weighted — spread across a full working year it is worth materially less than it appears. Tax-Free Childcare stacks on top and adds a government contribution to what you pay. Both are covered in detail in our guide to funded childcare hours in England.

Childcare policy is devolved, so Scotland, Wales and Northern Ireland run separate schemes with different entitlements.

The cost nobody puts in the total

Every figure above is money spent. The larger number for many households is money not earned: reduced hours or time out of work during the early years, and with it the pension contributions and salary progression that do not happen.

That is the part that compounds. A few years at reduced hours shows up not only in the pay packet at the time but in a lower salary base for a decade afterwards and a smaller pension at the end. When the childcare-versus-salary comparison looks like break-even — and with two children in full-time nursery it often does — this is the reason the break-even year is the wrong horizon for the decision.

What to actually do with this

1. Plan for the 0–4 period specifically, not for £250,000. The total across 18 years is not a bill; the childcare years are.
2. Claim Child Benefit from birth, whatever your income, and opt out of payment if the charge would apply.
3. Check whether pension contributions bring you under £60,000 of adjusted net income. Between £60,000 and £80,000 a salary sacrifice contribution can pay for itself twice — the tax relief and the restored benefit.
4. Treat reduced hours as a pension decision as well as an income one, and check whether contributions can continue at the previous level.

Frequently asked questions

How much does it cost to raise a child in the UK?
CPAG puts the cost of raising a child to 18 at about £250,000 for a couple and £290,000 for a lone parent, including rent, childcare and council tax. Stripping those three out, the basic cost is about £167,700 for a couple and £189,100 for a lone parent.

Why does it cost a lone parent more to raise a child?
There is no second adult to share the fixed costs of running a household, and childcare is harder to cover informally. The figures come from the Minimum Income Standard, which is built from what the public considers a decent standard of living rather than from what families actually manage to spend.

What is Child Benefit worth in 2026-27?
£27.05 a week for the eldest child and £17.90 a week for each additional child. Over 18 years the eldest child alone is worth roughly £25,000, which is a meaningful offset against the total.

At what income do you lose Child Benefit?
The High Income Child Benefit Charge begins when the higher earner has adjusted net income above £60,000, claws back 1% for every £200 above that, and removes the whole award at £80,000. Pension contributions reduce adjusted net income, so they can restore part or all of the benefit.

Should I still claim Child Benefit if I have to pay it back?
Yes — claim and opt out of payments. Claiming protects National Insurance credits toward your State Pension for a parent not otherwise working, and secures the child a National Insurance number automatically. Not claiming at all forfeits both.
