Compare the unit price of two products side by side to find the best deal. Enter each item's total price and quantity (number of items, weight, or volume) and the calculator returns the price per unit for both — plus highlights which option gives you more value for your money.

The unit price is the cost per single unit of a product — such as per ounce, per pound, per liter, or per item. It lets you compare products sold in different quantities or package sizes on an equal footing, so you can see which one truly costs less.
The unit price formula is straightforward: unit price = total price ÷ total quantity. For example, if a 3-liter bottle costs $3.99, the unit price is $3.99 ÷ 3 = $1.33 per liter. This calculator does that division for you and compares two items at once.
For a package containing multiple items (like a 12-pack of soda), enter the total number of cans as the quantity and the full package price as the total price. The calculator will divide the price by the number of items to give you the cost per can, which you can then compare against a different package size.
Divide the total price by the number of cans: $6.00 ÷ 12 = $0.50 per can. Enter 6 as the total price and 12 as the quantity in this calculator to confirm — and compare it against a 6-pack or individual bottle to find the best value.
Retailers often sell the same product in different sizes and package formats, making direct price comparison misleading. Calculating the price per unit removes the package-size variable so you can objectively see which option gives you more product for less money — especially useful for groceries and household staples.
Not necessarily. While bulk packages often have a lower unit price, this isn't always the case — especially with sale items, store brands, or promotional pricing on smaller sizes. Always check the unit price before assuming the larger size is the better deal.
Yes. Select your unit of measure (pounds, ounces, kilograms, liters, etc.) from the dropdown and enter the total weight or volume as the quantity. The calculator will return the price per pound, per liter, or whatever unit you choose — making it easy to compare a 32 oz jar against a 2 lb bag, for example.
The result tells you how much you pay for one unit of that product. A lower price per unit means better value. For instance, if Item 1 costs $0.45 per oz and Item 2 costs $0.38 per oz, Item 2 is the better deal regardless of the total package price.
