Compare two products side by side to find the best value for your money. Enter the total price and quantity (or weight/volume) for Item 1 and Item 2, and the Unit Price Calculator returns the cost per unit for each — plus highlights which item is the better deal.

The unit price is the cost per single unit of measurement — such as per ounce, per pound, per liter, or per item. It lets you compare products of different sizes or quantities on a common basis so you can identify the best value for your money.
Use the formula: unit price = total price ÷ total quantity. For example, if a 32 oz bottle costs $4.99, the unit price is $4.99 ÷ 32 = $0.156 per oz. The lower the unit price, the better the deal.
For multi-item packages, the 'quantity' is the total number of items in the pack. For example, a 12-pack of soda cans for $6.00 gives a unit price of $6.00 ÷ 12 = $0.50 per can. You can then compare that to a 6-pack at $3.50, which is $0.583 per can — making the 12-pack the better deal.
Divide the total price by the number of items: $6.00 ÷ 12 = $0.50 per can. If you're comparing this to a different pack size, use this calculator to find both unit prices side by side.
Retailers often package products in different sizes with different price tags, making direct comparison hard. Calculating price per unit puts both options on a level playing field, so you always know which option gives you more for your money — whether you're buying groceries, cleaning products, or beverages.
This calculator is most accurate when both items share the same unit of measure (e.g., both measured in ounces or both in liters). If you need to compare across different units (e.g., pounds vs. kilograms), convert one quantity to the other's unit first before entering the values.
Not always. While bulk sizes often cost less per unit, some retailers price larger packages at a premium or offer better deals on promotional smaller packs. Always check the unit price rather than assuming the bigger package is cheaper.
The savings percentage shows how much cheaper the better-value item is compared to the pricier option, expressed as a percentage. For example, a savings of 15% means the cheaper item costs 15% less per unit than the other — a useful figure when the unit price difference looks small in dollar terms.
