Save Money at the Grocery Store with Unit Pricing

Food is a large part of a family budget. To make the best choices and to get the most for your money, it is important to compare the price, amount, and quality of similar products.

Unit pricing can help.
The unit price tells you the costs per “unit” (such as per ounce, per pound, per sheet) to buy the product.

It is easy to find the unit price of some items. It may be marked on a sign near the item. For example:

• If apples sell for $.89 per pound, you know that 5 pounds will cost $4.45 (5 pounds X 89 cents).
• If potato salad sells at the deli counter for $2.59 per pound, you know that 2 pounds will cost $5.18 (2 X $2.59).

Unit pricing is most helpful when the price per unit is not so clear.

Let us look at an example.
Your favorite brand of corn flakes is sold in three different sizes.

• The 14-ounce box is $2.52.
• The 20-ounce box is $3.00.
• The 2-pound (32-ounce) box is $5.12

Which one is the best buy? Unit pricing helps. (In this case, the unit price is the price per ounce).

To figure the unit price, divide the price by the number of units. (In this example, it is the number of ounces).

• The unit price for the 14-ounce box is 18 cents per ounce ($2.52/14).
• The unit price for the 20-ounce box is 15 cents per ounce ($3.00/20).
• The unit price for the 2-pound box is 16 cents per ounce (2 pounds = 32 ounces; $5.12/32).

Compare the unit price for each package.

In this example, the 20-ounce package is the best buy because it costs less per ounce.

Remember, the larger package is not always the best buy. It pays to know the unit price.

Another way to compare costs
Corn flakes are also sold in the bulk food section for $1.44 per pound (one pound - 16 ounces). Divide $1.44 by 16, and you know the cost per ounce is 9 cents. ($1.44/16 - $.09)

How does the unit price of the boxed corn flakes compare with the unit price of the corn flakes sold in the bulk food section? In this example, the unit price shows that the corn flakes from the bulk food section are the better buy.

When you know the unit price, you can compare similar products of different sizes. Many states require supermarkets to mark the unit price on the shelves or the price tags. Other states may require that the information given be correct and easy to understand.

If you find that a unit price label or tag is missing or is not correct, report it to the store manager immediately.

What You Can Do:
Look for unit price labels on shelves or signs near the item

Compare the unit prices of similar products to find the best buy

If the unit price is incorrect or missing, report it to the store manager. Ask the manager to post or correct the unit price information.
