Frequently Asked Questions
Unit price is the cost per single unit of measurement (per ounce, per gram, per item). It helps you compare products of different sizes to find the best value. A larger package is not always cheaper per unit.
Divide the total price by the quantity. For example, if a 32oz bottle costs $4.00, the unit price is $4.00 / 32 = $0.125 per ounce. Compare this to other sizes to find the best deal.
Not always. Consider: will you use it before it expires? Do you have storage space? Sometimes paying slightly more per unit for a smaller size reduces waste and saves money overall.
Many stores show unit prices on shelf labels below the item. Look for "price per oz" or "price per count." Our calculator lets you compare when this information is not displayed.
