Family budget with kids: category by category

What does a child cost? What the data says

The best-known US figure comes from the Department of Agriculture’s Expenditures on Children by Families series, run since 1960 and used by many states for child support guidelines. The last report (Mark Lino and colleagues, published January 2017) covers 2015. It hasn’t been updated since, so read it for proportions rather than today’s dollars.

For a middle-income married couple with two children (before-tax income between $59,200 and $107,400 in 2015), spending on one child ran from $12,350 to $13,900 a year, depending on age. Over 17 years, that added up to $233,610.

Two more findings help with planning. An only child cost about 27% more than each child in a two-child family, and each child in a family of three or more cost about 24% less: bigger families share rooms, cars and hand-me-downs. And lower-income families spent 27% of before-tax income on a child, against 16% for middle-income and 11% for higher-income families.

Childcare is the line that varies most. The Labor Department’s Women’s Bureau, using its National Database of Childcare Prices, found that full-day care for one child cost $6,552 to $15,600 a year in 2022, or 8.9% to 16% of median family income, depending on the county and type of care.

Child-related income to count

Before listing costs, list what comes in because you have children.

• US Child Tax Credit. For 2025 returns, up to $2,200 per qualifying child, with up to $1,700 refundable, according to the IRS. If you get a refund, decide in advance where it goes (a sinking fund, the emergency fund) instead of letting it vanish into checking.
• Child and dependent care credit and dependent care FSAs. If your employer offers a dependent care FSA, it can lower the tax on childcare costs. Check the rules for your situation with the IRS or your HR team.
• UK Child Benefit. £27.05 a week for the eldest or only child and £17.90 for each additional child. Higher earners may have to pay some or all of it back through the High Income Child Benefit Charge; GOV.UK has a calculator.

The family budget, category by category

Here are the categories to plan, and what to watch in each.

• Housing and utilities. The largest line. Rent or mortgage, insurance, electricity, gas, water, internet.
• Groceries and household. Our grocery budget guide gives USDA food plan figures for a family of four and a weekly method.
• Childcare. Daycare, preschool, after-school care, summer camps.
• Transportation. Car payments, gas, insurance, maintenance, bus passes.
• Health. Premiums not paid by an employer, copays, dental, glasses, braces.
• Kids. School fees, lunches, activities, clothes, which children outgrow on a schedule.
• Allowance. See our guide to pocket money and allowance for amounts by age.
• Fun. Weekend outings, eating out, streaming.
• Sinking funds. Holidays, birthdays, back-to-school, summer, replacing appliances.
• Savings. Even a small amount, moved on payday.

A worked budget for a family of four

Marcus and Priya live in Raleigh, North Carolina, with Maya, 10, and Eli, 4, who is in preschool. Their take-home pay is $6,800 a month.

Eli’s preschool costs $10,800 a year ($900 × 12), inside the national range above. When he starts kindergarten, that $900 doesn’t become spare cash by default: they’ve agreed to move half to savings and half to after-school care and activities.

The costs that come once a year

These are what break family budgets. A month that balances perfectly can blow up in August (school supplies, fall sports fees, shoes) or in December. The fix is sinking funds: estimate the yearly cost, divide by twelve, and set that amount aside each month.

For Marcus and Priya: summer camp $1,500, holidays $1,200, birthdays $600, back-to-school $900. That’s $4,200 a year, or $350 a month. Our sinking funds guide shows how to keep them separate so they don’t get spent on groceries.

The monthly family money meeting

A family budget works when both adults see the same numbers. Once a month, say the first Sunday, take fifteen minutes:

Bringing the kids in doesn’t mean sharing your worries. A seven-year-old can choose between two outings that cost the same; a teenager can manage a clothing budget for the season. For how two adults split costs, our couples budget guide compares the three main models: all shared, all separate, and a mix.

Single parents: adjusting the plan

The USDA found that most single-parent households fell in the lowest income group, where a child takes the largest share of income. Three points help:

• Child support. Budget from the date it actually arrives, not the date it should.
• Benefits and credits. Check eligibility after any change in income or custody: in the US, 211 can point you to local programs; in the UK, MoneyHelper links to free benefits calculators.
• Shared custody. Agree in writing who pays for what (school lunches, activities, clothes), and keep a record of shared costs.

What Binome360 can do (and what it can’t)

Binome360 doesn’t connect to your bank. It lets you set up a shared “Family” assistant: each parent logs spending in one sentence from their own phone, in the same categories, with a budget per category. Recurring costs (mortgage, preschool, subscriptions) can be saved as recurring items, and a savings goal for camp or back-to-school shows progress month by month.

Frequently asked questions

How much does it cost to raise a child per year?

The USDA’s last estimate, for 2015, was $12,350 to $13,900 a year for a middle-income married couple with two children, depending on the child’s age. Costs have risen since, and childcare alone can run $6,552 to $15,600 a year (2022 data).

What percentage of a family budget should go to housing?

There’s no official rule. Many lenders look at your debt-to-income ratio instead. In our example, housing and utilities take 34%. Check what’s left after fixed costs with our guide to disposable income after bills.

How do you budget for a family on one income?

Start with fixed costs and childcare, which may be lower with a parent at home, then build sinking funds for yearly costs. Keep the monthly meeting even if one person handles the money day to day.

Should kids be involved in the family budget?

Yes, in age-appropriate ways: an allowance, a shared savings goal, a choice between options. Keep adult worries out of it.

In short

A family budget holds when it plans category by category for monthly costs, sets money aside for yearly ones, and gets fifteen minutes of attention from both parents each month. Count child-related credits and benefits as income, and decide where they go. First step tonight: list your family’s yearly costs (camp, holidays, birthdays, back-to-school) and divide the total by twelve.
