Comparing Prices with a Unit Price

Unit price converts a package price into a cost per common unit, making different package sizes easier to compare. Divide the total price by the quantity to find the price per item, kilogram, liter, ounce, meter, or other chosen unit.

Worked Unit Price Comparison

If a 750-gram package costs 6 and a 1-kilogram package costs 7.50, converting both to price per kilogram reveals which is cheaper on an equal basis. The larger package is not automatically the better value.

Check What Is Included

Use matching units and account for discounts, taxes, shipping, membership requirements, or usable quantity when they affect the real purchase cost. For concentrated products, serving size or dilution may be more meaningful than package weight. Unit price is a comparison aid; quality, waste, storage life, and how much you actually need can still make a higher unit price the better practical choice.

Choosing a Common Unit

Unit-price comparisons are meaningful only when quantities use the same unit. Convert grams to kilograms, milliliters to liters or multipacks to individual items before comparing when necessary. Also check whether package quantity refers to net contents, servings or another measure.
