Price Per Unit Calculator
Enter a package price and its quantity to see the price per unit. Run it on each option to compare package sizes — the lower unit price wins.
Find the unit price
The total price you pay, from $0 through $100,000,000.
How many units, ounces, or items are in the package.
$6.00 across 12 units. The lower the unit price, the better the value.
- Package price
- $6.00

- 12
How the unit price is calculated
The unit price is simply the package price divided by the quantity in the package. Comparing two options is only fair when both quantities use the same units — ounces against ounces, or items against items. The lower unit price is the better value for the same product.
Unit price = Package price ÷ Quantity$6 for 12 units
A package priced at $6.00 containing 12 units works out to $0.50 per unit ($6.00 ÷ 12). A competing package is a better deal only if its unit price comes out below $0.50.
General-purpose estimate.
What this calculator assumes
- Price and quantity are both for the same package.
- Comparisons are only meaningful when both packages use the same unit of measure.
- The quantity must be greater than zero.
- The unit price is shown to as many as four decimal places.
Price per unit FAQ
How do I compare two package sizes?
Calculate the unit price for each package using the same unit of measure, then compare. The package with the lower price per unit is the better value for that product.
What counts as a unit?
A unit is whatever you divide by — ounces, grams, sheets, count, or servings. Just be consistent so both packages are measured the same way.
