Frequently Asked Questions
What is unit price and why is it useful?
Unit price is the cost per standard unit of measure (e.g., per ounce, per liter, per count). It lets you compare products of different sizes to find the best value. A 32-oz bottle at $3.99 ($0.125/oz) is cheaper per unit than a 16-oz bottle at $2.49 ($0.156/oz).
Is the larger size always the better value?
Not always. While bulk sizes often have lower unit prices, this is not guaranteed. Some stores price smaller sizes competitively during sales. Always compare unit prices rather than assuming bigger is cheaper. Also consider spoilage for perishable goods; buying more than you need wastes money.
How do stores display unit prices?
In the US, many stores are required to display unit prices on shelf labels. They show the price per ounce, pound, count, or other standard measure. When not displayed, divide the total price by the quantity to calculate it yourself.
