Babies go through 2,500–3,000 diapers in their first year — at $0.20–$0.35 each, that adds up fast. Enter your baby's age, daily usage, and cost per diaper to project your total spend and compare disposable vs. cloth.

A baby goes through roughly 6,000 diapers before potty training — and the brand you buy changes the bill by thousands. Project your total spend by age, daily usage and brand, then see exactly when cloth diapers pay for themselves.

How to project your diaper budget in 3 steps

  1. 1Set your baby's stage

    Pick Newborn, Infant or Toddler — the daily-diaper preset fills in automatically. Tweak the age, diapers-per-day and potty-training target if you like.

  2. 2Price your diapers

    Tap a brand tier or type your exact cost per diaper. Premium brands run about $0.32 each, warehouse bulk about $0.20 — a gap that compounds fast.

  3. 3Compare against cloth

    See total diapers and dollars to potty training, the cloth-kit-plus-laundry total, and the break-even month — the moment cloth starts saving you money.

What makes this diaper math honest

Stage-based usage curve

Usage drops as babies grow — 10/day as a newborn, 8 as an infant, 6 as a toddler — instead of pretending one rate fits two-plus years.

Brand-tier quick picks

One tap compares premium, store-brand and bulk pricing so you see exactly what the fancy box really costs you.

Full cloth cost, not just the kit

The comparison adds laundry loads, water and electricity — the costs cloth evangelists sometimes forget — before declaring a winner.

Real break-even month

Not "cloth is cheaper eventually" — the exact month the kit pays for itself, computed from your own numbers.

Adjustable training age

Every baby is different. Move the potty-training target and the projection — diapers, dollars, everything — follows.

Month and year figures

Right-now monthly cost plus first-year spend, the two numbers that actually matter for a household budget.

Diaper cost questions, answered

How much do diapers cost per month?
At 10 diapers a day and $0.25 each, a newborn costs about $75 a month. At premium prices ($0.32) that is ~$96; at bulk prices ($0.20) about $60. Costs fall as daily usage drops — a toddler at 6 a day runs roughly $45 a month at store-brand prices.
How many diapers will my baby use in the first year?
About 2,500–3,000. The breakdown in this calculator: roughly 900 in the first 3 months (10/day), then about 2,160 over months 3–12 (8/day). Total to potty training at 30 months is roughly 6,000–6,500 diapers.
Are cloth diapers actually cheaper?
Usually, yes — if you use them long enough. A $400 cloth kit plus laundry (~$20/month) breaks even against $75/month disposables in about 7 months, then saves roughly $55 a month from there. Across two-plus years the savings often pass $1,000.
What does the cloth total include?
The upfront kit (diapers, inserts, covers — typically $300–$500) plus ongoing laundry: your cost per load × loads per week, covering water, electricity and detergent. It does not include your time — cloth is a few extra laundry loads a week.
When do babies potty train?
Most US children train between 24 and 36 months, with 30 months a solid planning average. If your toddler is an early or late trainer, move the "potty-trained at" field — the whole projection recalculates.
How much do diaper brands really differ in price?
A lot. Premium name brands run about $0.30–$0.35 per diaper, store brands $0.22–$0.28, and warehouse bulk packs $0.18–$0.22. Over 6,000 diapers, switching from premium to bulk can save $700+ — use the brand quick-picks to see it.
