Pro Tips
- •Price per unit lets you compare the true value of products sold in different package sizes
- •Larger packages aren't always cheaper per unit - always check rather than assuming bulk is a better deal
- •Use the same unit of measurement (like ounces or milliliters) when comparing two products side by side
- •Many stores post unit pricing on shelf tags, but calculating it yourself helps catch pricing that's rounded or hard to read

Frequently Asked Questions
How do I compare two different package sizes?
Calculate the price per unit for each package separately using the same unit of measurement, then compare the two results directly - the lower price per unit is the better value.
Does a bigger package always have a lower price per unit?
No. While bulk packaging is often cheaper per unit, this isn't guaranteed - sales, promotions, and store pricing strategies can sometimes make smaller packages the better deal.
Is my data sent to a server?
No. All calculations happen instantly in your browser using JavaScript. Nothing you enter is transmitted anywhere.
What if the packages use different units, like ounces vs. grams?
Convert both to the same unit first using a unit converter, then calculate price per unit for each so you're comparing like with like.
