How to Save Money Shopping

Retailers often perform "shrinkflation" reducing the size of a package while keeping the price the same. The only way to know if you are getting a deal is to calculate the Unit Price (Price per ounce, Price per item, etc.).

How to Use

  • Step 1: Enter the price of Item A (e.g., $5.00) and its quantity (e.g., 10 oz).
  • Step 2: Enter the price of Item B (e.g., $8.00) and its quantity (e.g., 20 oz).
  • Step 3: Our calculator instantly highlights the cheaper option and shows you exactly how much you save (e.g., "Save 20%").
