The real monthly cost of having a kid

Public headlines love the '$300,000 to raise a child' number. It's not wrong, but it's also not useful. What matters when you're deciding whether the numbers work is the monthly line item that's about to land on your budget — not a sum spread across 18 years. Here's what actually shows up.

Year one — the shock year

• Daycare or a lost income: the single biggest number. Infant daycare runs $220–$2,400/mo depending on city and subsidy. If a parent stays home, count the foregone take-home instead.
• Diapers, wipes, formula (if formula-feeding): $150–$400/mo. Formula alone can be $250/mo.
• Gear (crib, car seat, stroller): a $1,500–$3,000 one-time hit, most of it in the first three months.
• Extended health / life insurance changes: often $30–$100/mo more.

For a two-earner household in a mid-cost city with subsidized daycare, expect year one to add $1,200–$2,000/mo of ongoing costs on top of a few thousand of upfront spending. In a high-cost city with market-rate infant daycare, $2,500–$3,500/mo is normal.

Years two through five

Daycare stays the dominant number until school starts — toddler rates are typically 10–20% lower than infant. Food picks up, clothes cycle every 3–4 months at this age, and 'activities' start (swimming, music, preschool programs) at $50–$300/mo each.

The hidden housing cost

The line item nobody puts on the spreadsheet: the two-bedroom becomes a three-bedroom, or the downtown apartment becomes a suburban house with a car. Housing is where the '$300k' number actually comes from. If your current place doesn't fit a kid, the honest budget for kid #1 includes the delta between your current rent/mortgage and what a family-sized version will cost.

The Canadian $10-a-day daycare reality

Federal-provincial subsidies have cut licensed daycare fees dramatically in most provinces since 2022. The catch is capacity — waitlists in major cities are 12–24 months long, and non-subsidized spots or home-based care can still run $1,200–$1,800/mo. The honest planning approach: budget as though you'll pay unsubsidized rates for the first 6–12 months, then get the subsidy as a raise once a spot opens.

School-age years (6–18)

Daycare goes away but after-school care ($200–$600/mo), summer camps ($1,500–$5,000/year), activities ($100–$500/mo), food (a teenager eats like a full adult, plus 30%), and eventually driving (insurance for a teen driver: +$100–$300/mo) fill the gap. On average, these years cost 40–60% of what daycare years cost, but they're steadier and easier to plan.

Post-secondary

In Canada, tuition and residence for a 4-year degree runs $60,000–$100,000 in-province, more out-of-province. In the US, in-state public is $80,000–$120,000; private or out-of-state is $200,000–$350,000. The RESP (Canada) and 529 plan (US) let this grow tax-sheltered. To fully fund a Canadian in-province degree via RESP, you need to save about $150–$200/mo from birth. For US in-state, $250–$350/mo. Most families don't fully fund and rely on a mix of savings, income during school, scholarships, and student loans.

The stress-test question

The one worth answering honestly: on one income for 12 months, do the numbers still work? Parental leave benefits typically replace 55–67% of income (capped) in Canada and vary wildly in the US. If your current surplus can't absorb a one-earner year with a new set of baby-related expenses, that's the gap to close before, not after.

Frequently asked questions

Do subsequent kids cost the same? No — hand-me-downs, shared bedrooms, and existing gear make kid #2 significantly cheaper than kid #1, often 30–50% less. Daycare is the main exception (still full price per kid), but sibling discounts exist in many centres.

What about private school? Fully optional and often $10,000–$30,000/year per child in Canada, $15,000–$50,000 in the US. Do the total cost across 12–14 years and compare it to the retirement contribution you'd make instead — the numbers are startling.

The takeaway

The right number isn't a lifetime total — it's the honest monthly delta on today's budget. Model your specific city's daycare rate, subtract any government benefits you'd qualify for, add the housing delta if a bigger place is needed, and see whether the surplus survives. If it does, you're ready. If it doesn't, you know exactly what to close before you're ready.
