Diaper & wipes cost calculator

Buy small first, bulk later

Newborns can fluctuate 1–2 pounds in the first weeks, which sometimes means jumping size faster than expected. One box of newborn diapers and one box of size 1 is enough to start. Buy bulk only after you know what fits.

Subscription savings vs. warehouse clubs

Subscribe & save services on disposable diapers typically save 5–15% off list price. Costco and Sam's Club box prices on store brands are often even cheaper on a per-diaper basis. The cheapest combo is usually store-brand diapers from a warehouse club, with subscription wipes for convenience.

Cloth diapering: upfront vs. recurring

A usable cloth diaper stash runs $350–$1,000. After that, you're paying for detergent, water, electricity, and a few replacement covers. The savings really show up in year two — and in much larger savings if you reuse the same stash for a second baby.

Don't over-buy wipes either

Wipes do not "expire" the way some other baby products do, but unopened tubs can dry out over time. A month or two of supply at a time is usually plenty.
