How this works

The calculator takes your baby's current age and projects costs forward to your expected potty training date. It accounts for diaper size changes (bigger diapers cost more) and shows you the total spend for each method.

For disposables, it multiplies your daily count by the per-diaper price across every remaining month. For cloth, it adds the upfront diaper cost, ongoing laundry, and accessories. The hybrid option assumes cloth at home and disposables on the go.

Common mistakes to avoid

Forgetting laundry costs. Water, electricity, and detergent add up. Parents who skip this line often overestimate cloth savings by 20-30%.
Ignoring size jumps. A size 5 diaper can cost 40% more than size 2. The calculator adjusts for this automatically.
Underestimating daily count. Newborns go through 10-12 diapers a day. Using 6-8 for a 2-month-old will skew your numbers low.
Not counting accessories. Cloth diapers need wet bags, a sprayer, and special wipes. Budget $40-80 for startup extras.

Edge cases worth knowing

Twins: Double the daily diaper count but keep cloth diaper counts the same (you'll wash more often, not buy twice as many). The calculator handles this if you set daily count to 16+.

Sensitive skin: Premium brands or special cloth diaper liners can add $15-30/month. Add that to the monthly extras field.

Diaper rash treatment: Prescription creams and frequent changes during rash episodes can spike costs by $20-50 in a bad month. This isn't modeled but worth keeping in mind.

Second child reuse: Cloth diapers used for a second child drop your per-child cost dramatically. If you plan to reuse, divide your cloth startup cost by 2 for a more honest comparison.

What the numbers don't show

Time is a real cost. Cloth diapering adds 3-5 loads of laundry per week. For some families, that time is worth more than the savings. Others find the routine manageable. Only you can weigh that trade-off.

Environmental impact matters too. Disposable diapers generate roughly 2 tons of waste per child. Cloth diapers use more water and energy. Neither choice is perfect. This page focuses on cost because that's what most parents ask about first.

Questions parents ask

: Use the Custom tier and enter your average cost per diaper. For a rough estimate, add up what you spent last month and divide by the number of diapers used. That gives you a realistic per-diaper number.
: In most cases, yes. Typical savings range from $500 to $1,500 over the full diapering period. The biggest factor is your local water and electricity cost. Families in high-rate areas see smaller savings. Reusing cloth diapers for a second child nearly doubles the savings.
: Those costs are similar across all methods, so they don't change which option is cheapest. But they do affect your total budget. Add your monthly estimate in the Extras field to see the full picture.
: Most children potty train between 24 and 36 months. The calculator defaults to 30 months. If your child trained early or late with an older sibling, adjust accordingly.
