A typical US family of four spends roughly $6,000–9,000 per month in 2026 — housing at ~30%, groceries between $993 (USDA Thrifty) and $1,627 (Liberal), transportation near $1,200, with childcare as the swing variable that can add $2,000+ or nothing at all. Here are the averages and a template built on them.

Family of 4 monthly budget: the averages

Category	Monthly range	Notes
Housing (mortgage/rent + utilities)	$2,000–2,900	~30% of spending nationally
Groceries	$993–1,627	USDA food plans, family of 4
Transportation (usually 2 cars)	$1,000–1,400	payments, insurance, gas
Healthcare & insurance	$600–900	employer plan assumed
Childcare / school costs	$0–2,500+	the wild card — see below
Eating out & entertainment	$400–700
Clothing, personal, misc	$350–550
Total	~$6,000–9,000	before savings

Benchmarks: average household expenses; location moves everything — the same family runs $5,500–8,000 in Houston and $9,000–14,000 in NYC.

The two numbers that decide the budget

Childcare is binary: two kids in full-time care can cost $2,000–4,500/month — rivaling the mortgage — then drops to school-age numbers almost overnight. Budget the expensive years as a phase with an end date, and pre-decide where the freed money goes when it ends (hint: the 35 checkpoint is usually waiting). Groceries are the controllable one: the USDA's own Thrifty-to-Liberal spread is $634/month for the identical family — meal planning and store choice are worth more than any subscription audit.

A template that survives real life

Classic 50/30/20 strains with kids — needs often run 55–65%, and that's structure, not failure. What matters: savings automated first (pay yourself first, even if 10%), sinking funds for the predictable irregulars (school-year startup, sports, holidays, car repairs — a family of four has many), and both parents seeing the same numbers (shared budget, right app). Four people generate hundreds of transactions a month; the budget only stays true if capture is effortless — voice logging and automatic Apple Pay import in Lumi exist for exactly this volume.
