How much does a newborn cost per month?

Roughly $74–$386 a month for the essentials (before childcare). The one line we can price exactly is diapers: at ~240 changes a month, from $29 on the cheapest per-diaper price to $116 at the median we track. Formula, wipes, clothing and healthcare add the rest.

What we measure vs estimate. The diaper line is a live median from the diapers we track, times ~240 changes/month. The other lines are typical US ranges, not our data. Childcare is excluded — at $800–$2,000+/month it dwarfs everything and depends entirely on your situation.

The one line you can actually cut

Diapers are unavoidable but the price is not fixed — it swings 3–5× for the same job depending on the per-diaper price you pay. Buying by cost per diaper instead of box price, and using store brands for daytime changes, is the difference between the low and high ends of that line. Over a year of ~2,500 diapers, that gap is hundreds of dollars.
