How to Use This Calculator
Enter family basics
Start with number of babies, price per diaper, and typical wipes usage per change.
Review stage assumptions
Adjust months and diapers/day based on pediatric guidance or your own experience.
Check budget totals
Use the totals to plan monthly budgets, subscribe-and-save orders, or registry requests.
Formula
Stage Days ≈ Months × 30.44
Stage Diapers = Diapers/Day × Stage Days × Babies
Stage Cost = Stage Diapers × Cost per Diaper
Total = Σ Stage Values
Example: 6 months × 30.44 days × 8 diapers/day × 1 baby = 1,460 diapers → $408.80 at $0.28/diaper.
Smart Diaper Stocking
- Buy in smaller quantities early on—babies size up quickly.
- Use subscription services to lock in lower prices and cancel anytime.
- Track actual usage weekly to refine your diaper/day assumptions.
- Factor in cloth diaper days or nighttime pull-ups to adjust totals.
