Cost of Raising a Child Calculator: USDA Figures 2026

One division turns a USDA total into your yearly cost

The USDA’s “Expenditures on Children by Families, 2015” report adds up everything a middle-income married couple with two children spends on a child born in 2015, from birth through age 17: $233,610.00. Divide by 18 and you have the annual cost — $12,978.33 a year, $1,081.53 a month, $35.56 a day. On the defaults — Middle income, 1 child, age 0, 2015 USDA dollars — the annual cost is $12,978.33, the monthly cost is $1,081.53, the daily cost is $35.56, the total birth to 18 is $233,610.00, the remaining cost is $233,610.00 (18 years left) and the already-spent cost is $0.00.

Where the money goes — annual cost by category

Housing is the biggest slice — $3,763.72 a year, 29% of the total — because a child means a bigger home in a pricier school district. Childcare and education is next at $2,336.10 (18%), then food $2,076.53 (16%), transportation $1,946.75 (15%), health care $1,168.05 (9%), miscellaneous $908.48 (7%) and clothing $778.70 (6%). The shares add to 100% and the annuals add to $12,978.33. At the defaults — Middle income, 1 child, age 0, 2015 USDA dollars — the annual cost is $12,978.33, the monthly cost is $1,081.53, the daily cost is $35.56, the total birth to 18 is $233,610.00, the remaining cost is $233,610.00 and the already-spent cost is $0.00. Check the identities: annual = total ÷ 18; monthly = annual ÷ 12; daily = annual ÷ 365; total for N children = total × (1 + 0.78 × (N − 1)); remaining = annual(N) × (18 − age); spent = annual(N) × age; category = annual × share. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum.

The worked example, line by line

Setup: Middle income, 1 child, age 0, 2015 USDA dollars.

Line 1 — the band total. The USDA middle-income total is $233,610.00 from birth through age 17, in 2015 dollars.

Line 2 — the annual cost. $233,610.00 ÷ 18 = $12,978.33 a year. That is $12,978.33 ÷ 12 = $1,081.53 a month, and $12,978.33 ÷ 365 = $35.56 a day.

Line 3 — the remaining cost. At age 0 there are 18 years left, so the remaining cost is $12,978.33 × 18 = $233,610.00 and the already-spent cost is $12,978.33 × 0 = $0.00.

Line 4 — the categories. Housing is 29% of the annual cost: $12,978.33 × 0.29 = $3,763.72. Childcare and education is 18%: $2,336.10. Food is 16%: $2,076.53. The seven annuals add to $12,978.33.

Reverse: the total birth-to-18 at $15,000/yr is $270,000.00 (exact $270,000.00); the forward is $15,000.00/yr. The first age where the remaining cost drops below $100,000 is 11 (remaining $90,848.33); at age 10 it is $103,826.67. The children for a total over $500,000 are 3 (total $598,041.60); 2 children cost $415,825.80. The monthly budget for a $200,000 remaining cost over 10 years is $1,666.67/mo (exact $1,666.6667); the rounded figure forwards to $200,000.40 — the rounded monthly figure overshoots by 40 cents. The 2022-adjusted LOW total is $232,265.69 (exact $232,265.6883); multiplier 1.329588. The age where spent equals remaining is 9 (spent $116,805.00, remaining $116,805.00); at age 8 spent is $103,826.67 and remaining is $129,783.33.

Every branch, checked

Low income: Annual $9,705.00, monthly $808.75, daily $26.59, total $174,690.00, remaining $174,690.00, spent $0.00. The low-income total is $174,690.00 — about 75% of the middle total — because housing and childcare cost less at the low end.

High income: Annual $20,678.33, monthly $1,723.19, daily $56.65, total $372,210.00, remaining $372,210.00, spent $0.00. The high-income total is $372,210.00 — about 59% more than the middle total — driven by pricier housing, childcare and education.

2 children: Annual $23,101.43, monthly $1,925.12, daily $63.29, total $415,825.80, remaining $415,825.80, spent $0.00. The second child costs 78% of the first, so two children cost $415,825.80 — not twice $233,610.00. The multi-child factor is 1.78.

3 children: Annual $33,224.53, monthly $2,768.71, daily $91.03, total $598,041.60, remaining $598,041.60, spent $0.00. Three children cost $598,041.60 — the factor is 2.56 — and that is the first count whose total passes $500,000.

Age 10: Annual $12,978.33, monthly $1,081.53, daily $35.56, total $233,610.00, remaining $103,826.67, spent $129,783.33. The annual cost is unchanged at $12,978.33 — the annual cost does NOT change with age, only the years left change. With 8 years left the remaining cost is $103,826.67 and $129,783.33 is already spent.

Age 15: Annual $12,978.33, monthly $1,081.53, daily $35.56, total $233,610.00, remaining $38,935.00, spent $194,675.00. With 3 years left the remaining cost is $38,935.00 and $194,675.00 is already spent.

2022 dollars: Annual $17,255.83, monthly $1,437.99, daily $47.28, total $310,605.00, remaining $310,605.00, spent $0.00. The Brookings update lifts the middle total to $310,605.00 and the annual cost to $17,255.83 — the straight $310,605 ÷ 18. Brookings’ own reported average of $18,271/yr is the inflation-projected average, not the calculator’s figure.

2022 Low income: Annual $12,903.65, monthly $1,075.30, daily $35.35, total $232,265.69, remaining $232,265.69, spent $0.00. The 2022-adjusted low total is $232,265.69 — the $174,690 total times the 1.329588 multiplier.

2022 High income: Annual $27,493.66, monthly $2,291.14, daily $75.33, total $494,885.87, remaining $494,885.87, spent $0.00. The 2022-adjusted high total is $494,885.87 and the annual cost is $27,493.66.

What the defaults assume

The model assumes the USDA’s national averages for a married couple with two children — single-parent and one-child families differ, and the totals exclude college, prenatal care, and lost income from reduced work hours. It assumes the 2015 figures are the latest official ones (the USDA stopped publishing the report after the 2017 edition) and that the 2022 basis is Brookings’ inflation update, not a new USDA number. It assumes each additional child costs 22% less than the first, and that the annual cost does not change with age — only the years left change. At age 17 there is one year left: remaining $12,978.33, spent $220,631.67. With 6 children the factor is 4.90 and the total is $1,144,689.00 — $63,593.83 a year. With 2 children in 2022 dollars the total is $552,876.90. Age 18 is a validation error at the calc level — the USDA total runs birth through 17, so an 18-year-old is past the table. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum; the reverses are nearest-value solutions, and the exact unrounded figures ($270,000.00, $1,666.6667, $232,265.6883) are stated wherever the rounded figures appear.

Who uses this

• The expectant parent budgeting for a first child: they learn one child costs $233,610.00 from birth to 18 — $1,081.53 a month — and they check the low-income branch ($174,690.00) to see the floor.
• The parent of two wondering about a third: they learn three children cost $598,041.60 — and they check the 2-children branch ($415,825.80) to see the second child adds only 78% of the first.
• The parent of a 10-year-old planning ahead: they learn $103,826.67 is still to come — and they check the age-15 branch ($38,935.00) to see how fast the remaining cost falls.
• The saver setting a monthly target: they learn $1,666.67/mo covers $200,000 over 10 years — and they check the 2022 branch ($17,255.83/yr) to see the inflation-adjusted annual cost.

Accuracy & limitations

The math is first-principles USDA arithmetic: annual = total ÷ 18; monthly = annual ÷ 12; daily = annual ÷ 365; factor = 1 + 0.78 × (children − 1); total = total × factor; remaining = annual(N) × (18 − age); spent = annual(N) × age; category = annual × share. The 4-decimal exact is shown where the rounding matters: the monthly budget for a $200,000 remaining cost is $1,666.6667/mo (shown as $1,666.67/mo); the rounded figure forwards to $200,000.40 — 40 cents over. The 2022-adjusted LOW total is $232,265.6883 (shown as $232,265.69); the multiplier is 1.329588. What the model cannot do is price YOUR child: it is a national average for a married couple with two children, it excludes college, prenatal care and lost income, and it assumes the annual cost is flat across ages — in reality childcare is dearest early and food, transport and activities grow as the child grows. For the college costs this total excludes, see the 529 plan vs Roth IRA for college comparison; for the monthly budget that pays for it, see the emergency fund calculator; for the tax side, see the 2026 federal tax brackets; and for the health side, see the child BMI calculator.
