Compare products by unit price to find the best deal
The Unit Price Calculator helps you find the best value by comparing the cost per unit of two products. Whether you're shopping at the grocery store, buying in bulk, or comparing different package sizes, the unit price reveals which option gives you more for your money.
Unit pricing is a standard practice in retail — it appears on shelf labels in most supermarkets — but not all stores display it clearly. This calculator puts the power in your hands, allowing you to compare any two products regardless of package size or unit type.
Not always. A lower unit price usually means better value, but consider factors like perishability — buying a massive bulk pack of something that spoils before you use it isn't a good deal even if the unit price is lower. Also consider storage space and upfront cost.
Convert both to a common unit before comparing. For example, to compare a 16 oz item with a 1 lb item, convert both to ounces (1 lb = 16 oz). This calculator shows the unit price in the unit you selected, so choose matching units for accurate comparison.
For count-based products (e.g., "count"), the unit price is simply the total price divided by the number of items. This works for anything sold by quantity — eggs, batteries, paper towels, or any multi-pack item.
Generally yes, but not always. Sometimes "bulk" sizes are priced at a higher per-unit cost because of packaging, brand positioning, or convenience. Always check the unit price — this calculator helps you verify that buying larger sizes actually saves money.
This calculator expects the same unit for both products. If products use different units (e.g., one in oz and one in lb), convert manually before entering: 1 lb = 16 oz, 1 kg = 1000 g, 1 L = 1000 mL. Enter the quantity in the smaller unit for both.
