Enter your stock and usage, then select Check result.

Formula and assumptions

Enter the pads used by the whole household each day. For a one-pet use rate, check the per-pet option and enter the number sharing the supply. An optional pack price shows monthly consumption costs.

Multiply pads per pack by packs remaining, then divide the total by daily household use. If the per-pet option is checked, multiply daily use by the number of pets first.

Why the result can vary

Pad size, absorbency, placement count, time away, and health can change replacement frequency.

Example

Check how long the remaining pads last

Inputs: 100 pads, 4 per day

Outcome: About 25 days of stock, with the estimated run-out date shown alongside.

Cautions

  • This calculator is not a reason to reduce changes needed for hygiene or health.
  • Prepare additional supplies before the estimated run-out date.

Frequently asked questions

What if each pet uses a different number of pads?

Add their daily changes and enter the household total. If each pet uses the same number, select the per-pet option and enter how many pets share the supply.

Can large and small pads share one calculation?

If one pad does not represent the same replacement, save them as separate items.

Can I include extra pads for travel?

Yes. Use the travel-supplies view with trip days and a safety allowance to calculate the pad item separately.

Pee pad duration calculator guide

Use pads per pack, packs remaining and pads used each day to estimate how long your puppy or dog pads will last. Add the pack price to see consumption costs too.

  • Enter the pad count in one pack and the packs you have. A partly used pack can be entered as a fraction, such as 0.5.
  • Enter total pads used each day. For one pet's daily amount, select the per-pet option and enter pet count; do not multiply a household total again.
