How Many Salt Bags Do You Need? Bundle & Refill Guide

Choose a water softener salt bundle using your measured consumption, bag weight, and storage space. A larger bundle should usually last longer; it does not necessarily need to arrive every month.

Calculate the salt in a bundle

Total pounds = bag weight × number of bags.

Bag size 2 bags 3 bags 4 bags 6 bags
25 lb 50 lb 75 lb 100 lb 150 lb
40 lb 80 lb 120 lb 160 lb 240 lb
44 lb 88 lb 132 lb 176 lb 264 lb

This table shows arithmetic examples. Available bag sizes and pack quantities vary by product; select the options shown on the product page.

Estimate how long your bundle lasts

Months of supply = total bundle pounds ÷ measured pounds used per month.

For example, a four-pack of 40 lb bags contains 160 lb. At 40 lb per month it lasts approximately four months; at 80 lb per month it lasts approximately two months. These are planning examples, not household consumption predictions.

Choose your refill schedule

  1. Track how much salt you add over a representative period.
  2. Check the tank and refill instructions in your softener manual.
  3. Choose a bundle that fits your dry storage space.
  4. Select an available subscription frequency that supplies salt before you run out, without accumulating more than you need.
  5. Review your schedule when household water use changes.

Compare value accurately

Cost per bag = bundle total ÷ bag count. Cost per pound = bundle total ÷ total bundle pounds. Review the actual recurring charge and frequency before subscribing.
