Grocery Unit Price Comparator

How to calculate unit price?

Unit pricing helps you compare items of different sizes by calculating the cost of a standard amount (like 1 oz or 100g).

Formula: Price / Quantity = Unit Price.

Using the comparator: an example

Suppose you are comparing a 16oz box of cereal for $4.00 and a 24oz box for $5.50.

Step-by-step calculation:

• Divide $4.00 by 16 to get $0.25 per oz
• Divide $5.50 by 24 to get $0.229 per oz
• The 24oz box is the better deal

Frequently Asked Questions

Is the bigger package always cheaper?

Not always. Stores sometimes offer promotions on smaller sizes that beat the bulk price.

What if units are different?

Always convert to the same unit (e.g., both to grams) before comparing to ensure accuracy.
