The bigger package isn't always the better deal — different pack sizes and pricing can make it genuinely hard to tell which product is cheaper per unit just by glancing at the shelf price. This tool does the division for you instantly.
Enter the price and size (in whatever unit both products share — grams, ounces, count, milliliters) for two products, and the tool calculates and compares the true price per single unit for each.
It's a quick way to settle the classic "is the bigger size actually cheaper" question while grocery shopping, comparing subscription tiers, or evaluating any purchase priced by quantity.

Frequently asked questions
Do both products need to use the same unit of measurement?
Yes, for a meaningful comparison both sizes should be entered in the same unit — grams to grams, or count to count, for example.
What if the unit prices are very close?
When the difference is small, other factors like quality, expiration date, or convenience may matter more than the marginal price difference.
