Amazon changes prices many times a day, so the price itself is on Amazon: the order here is by price per diaper at the last check. Multi-packs are ranked by their total count.

How to read this

Diapers come in bags of 20 and boxes of 200, and a size 1 diaper costs less than a size 6, so the sticker price tells you very little. Dividing the price by the number of diapers in the pack gives the only number worth comparing: cents per diaper. Store and value brands usually land around 15 to 25 cents per diaper in the small sizes, name brands around 25 to 45 cents, and premium plant-based brands anywhere from 50 cents to over a dollar.

The list covers disposable baby diapers sold on Amazon.com from preemie through size 8. Training pants, swim diapers, wipes bundles and gift sets are left out so that every row is a plain pack of diapers. Use the filters to narrow it to one size, one brand or overnight diapers only, and the cheapest per-diaper option in that group is always at the top.
