Compare two items by price per unit — enter each one's price and size to see which is actually the better deal.
Compare items in the SAME unit (both in oz, both by count, etc.). The lowest price per unit is the better value — before factoring in whether you'll use it all. General information.
A bigger package isn't automatically cheaper. Dividing price by quantity gives price per unit — the apples-to- apples number that tells you which option actually costs less.
Unit price = price ÷ quantity · Lower wins
Yes — compare ounces to ounces or count to count. Mixing units makes the per-unit prices meaningless.
Only if you'll use it. A bulk deal you throw half of away isn't a saving — factor in waste and shelf life.
