Unit Price Calculator
Compare two packages by price per unit so you can see which option is cheaper before you buy.
Item A
Item B
Comparison
Enter package prices and quantities to compare value.
How to compare unit prices
Enter the package price and quantity from the label. For the fairest comparison, use the same unit for both items. The lower price per unit is usually the better value, but brand, quality, and waste can still matter.
Example shopping checks
- Grocery shelf comparison — Compare 12 oz and 20 oz packages when sale stickers hide the better value.
- Bulk purchase decision — Check whether a larger package is actually cheaper per unit.
- Different unit labels — Use the custom unit field when the package uses servings, sheets, capsules, or pieces.

Frequently asked questions
What units can I compare?
Use ounces, pounds, grams, kilograms, milliliters, liters, each, or a custom unit label. The calculator compares matching units directly.
Does this tool save my entries?
No. The calculation runs in your browser, and your entries stay on your computer unless you copy the result.
Can I compare only one item?
Yes. Fill out item A only to calculate its unit price, or add item B to compare two options.
