Your adult diaper cost per month depends on the price per product, how many you use in a normal week, and how many extra changes you need. The calculator below turns your routine into a weekly cost, monthly estimate, and reorder point.

How to read your estimate
The calculator separates usage from cost so you can see what drives the monthly total. Treat the result as a planning estimate, not a recommended number of changes.
- Weekly units is the total number of products entered across all rows.
- Weekly cost multiplies each row’s units by its price per product.
- Monthly units and cost use 52 weeks divided by 12 months.
- Reorder point estimates how many products remain when your chosen backup window begins.
Compare price per product, not price per package
Package prices can be misleading when package counts differ. Divide the package price by the number of products in that package before comparing options.
Price per product = package price ÷ products in the package
The calculator uses editable one-time USD prices. Taxes and shipping are excluded, so replace the defaults with your actual checkout prices when needed.
Include extra changes and unused products
Extra changes can raise the monthly estimate, while unused products may carry into the next month. Count an ordinary week rather than your best or most difficult day.
- Add products used after leaks or fit problems.
- Include pads, guards, or boosters used with other protection.
- Leave out products you bought but did not use that week.
- Check fit before ordering a larger quantity.

Use the reorder point to plan ahead
The reorder point shows how many products equal your chosen backup-supply window. A seven-day setting means the result represents about one week of supply at the usage you entered.
Choose a larger backup window if deliveries to your area often take longer. Recalculate whenever your routine or product mix changes.
Turn the estimate into a recurring order
Use the monthly-unit estimate as a starting quantity, then compare it with whole package counts. Your first order may cost more than the prorated estimate because products are sold in full packages, while unused products can carry forward.
A recurring delivery works best when its quantity and interval match actual use. See How to Avoid Running Out or Stockpiling before choosing a schedule.
