Unit Price Calculator
Compare per-unit prices from total price and quantity.
Usage examples
Comparing products with different package sizes
A 500g pack and a 1kg pack of the same product are hard to compare by price alone. Pick Weight to convert both to a price-per-gram for a fair comparison.
Comparing drinks by price per liter
Compare a multi-pack and a single bottle with different volumes by converting both to a common volume unit to see which is cheaper.
Comparing bulk packs by price per item
Compare a single item's price against a bulk pack (say, a 10-pack) by count to see which works out cheaper per item.
Frequently asked questions
Is my price information sent to a server?
No. All calculations run entirely in your browser, and nothing you enter is ever sent to a server.
What does the green highlight mean?
It marks the product with the lowest price per unit among the ones you've entered — in other words, the best value.
Can I mix weight, volume, and count in one comparison?
No. For the comparison to make sense, every product needs the same basis (e.g. all weight), so picking one basis applies it to every row.
How many products can I compare at once?
You can add anywhere from 2 up to 6 products to compare.
