Diapers are one of the most significant recurring expenses of early parenthood. The Diaper Calculator estimates how many diapers you need and what they will cost over a given period. The average baby uses 6,000-8,000 diapers from birth to potty training at age 2-3, costing $1,500-$3,000+ depending on brand and where you shop. Newborns go through the most diapers (10-12 per day), with usage gradually decreasing as the child grows. This calculator helps parents budget for diapers, compare costs between brands, and plan bulk purchases. Knowing your monthly diaper budget also helps evaluate whether cloth diapers, subscription services, or store-brand alternatives would save money.
