Unit Price Calculator | Compare Price per Unit
Compare products by price per item, gram, kilogram, liter, ounce, or custom unit so bulk packs and different sizes are easier to judge.
Compare Products by Price per Unit
Enter the package price and quantity to calculate cost per unit for groceries, supplies, subscriptions, bulk packs, refill sizes, and product bundles.
Use the Same Unit for Fair Comparisons
A large package is not always cheaper. Convert products to the same unit, such as price per kg, liter, ounce, piece, or serving, before choosing the better value.
When Unit Pricing Helps
Use it while comparing supermarket packs, online listings, office supplies, pet food, cosmetics, supplements, or any product where size and price vary together.

Frequently Asked Questions
Can I compare two products with different unit sizes?
Yes. Enter both products with their respective prices and quantities and the tool normalises them to the same unit for a direct comparison.
Does it work for price per litre vs price per millilitre?
Yes. Select the appropriate unit and all comparisons are normalised automatically.
Can I use it for cost per serving rather than per gram?
Enter the number of servings as the quantity and price per pack as the price to get the cost per serving.
