What Is Unit Price?
Unit price is the cost of a product for one standard unit of quantity. It allows you to compare products that are sold in different package sizes.
For example, one package may cost more overall but contain significantly more product. Looking only at the package price can make comparisons misleading. Unit price provides a more useful way to compare the actual cost.
The basic calculation is:

Why Compare Unit Prices?
Unit prices make it easier to compare products when package sizes are different. A larger package is not automatically the better value, and a lower shelf price does not always mean a lower cost per unit.
Comparing unit prices can help when shopping for food, cleaning supplies, personal care products, office supplies, and other regularly purchased goods.
The comparison becomes especially useful when two products have different package weights, volumes, or quantities.
Unit Price Examples
Suppose a package costs $6 and contains 12 ounces. The unit price is:
Another package may cost $8 and contain 16 ounces. Its unit price is:
Although the second package costs more at checkout, both products have the same price per ounce in this example.
Unit Price Formula
The unit price formula is straightforward:
For example, if a product costs $10 and contains 20 units:
The same principle can be used for weight, volume, or individual items as long as the quantity and unit are clearly defined.
