Diaper Cost Calculator: How Many Diapers and What They Cost
Estimate the diapers your baby will use from now until potty training, with daily counts that drop as they grow, the cost of disposables with wipes, and the cost of cloth diapers with laundry, to compare the two.
Diaper Cost Calculator: How Many Diapers and What They Cost: Diapers are added up stage by stage, months times days times diapers a day. With the starting values, from birth to 30 months, that is about 5,500 diapers, costing about 1,400 at 0.25 each, plus wipes; cloth costs the kit up front and then laundry each month.

The daily counts are typical starting points; newborns are changed most often, and use drops as babies grow. Many children leave diapers between 2 and 3 years old. Cloth costs more at the start, and less if it is reused for a second child; laundry covers water, energy, and detergent.
Buying in bulk
Compare the price per diaper, not per pack; the unit price calculator does this across pack sizes.
Sizes
Babies move up a size by weight rather than age; buying too many of the small sizes ahead is a common waste.
How to use it
- Enter your baby's age and when you expect them to leave diapers.
- Adjust the diapers a day for each stage and the price per diaper.
- Compare the disposable and cloth totals.

How many diapers does a newborn use?
Often 8 to 12 a day in the first weeks, falling to about 5 or 6 a day for toddlers.
When do children stop wearing diapers?
Many between 2 and 3 years old during the day, and later at night; every child is different.
Are cloth diapers cheaper?
Usually over the whole time, and more so if reused for a second child, but they cost more at the start and need washing.
