Why Stockpile Diapers?

Financial planning for a new baby? Diapers are one of the biggest recurring costs. This tool visualizes the entire first year of diaper changes, helping you budget monthly or plan a bulk-buying strategy to save hundreds of dollars. Babies go through 2,500+ diapers in their first year alone! Building a stockpile before the baby arrives spreads the cost over months and protects you from inflation. Use our calculator to figure out the right mix of sizes so you don't get stuck with 5 boxes of Newborn size when your baby is already 12 lbs.

Smart Saving Tip

Target "Cost Per Diaper" when buying. A good stock-up price is under $0.15 for size 1 and under $0.25 for larger sizes.

Frequently Asked Questions

How much do diapers cost for the first year?

The average cost of disposable diapers for the first year is between $800 and $1,000 depending on the brand (generic vs. premium). Wipes will add another $200-$300 to your annual budget.

How many diapers does a baby use in the first year?

On average, a baby will use 2,500 to 3,000 diapers in their first year. This averages out to about 8-10 diapers per day for newborns and 6-7 per day as they get older.

How many boxes of Newborn diapers do I need?

Most babies only stay in Newborn (NB) size for 2 to 4 weeks. You typically only need 1 to 2 large boxes (approx. 200-250 diapers total). Do not overbuy NB size as big babies might skip it entirely!
