How the unit price calculator works
Compare package prices using the same quantity unit for both products, such as ounces, grams or item count.
Unit price = package price ÷ package quantity. Relative saving = (higher unit price − lower unit price) ÷ higher unit price × 100.
Read our calculation methodology and limitations.
Example
Twelve items for $6 cost $0.50 each. Twenty items for $9 cost $0.45 each: 10% less per item, although the larger package costs more upfront.
What affects the result
- Use matching units and comparable products.
- Account for waste if you will not use the larger package.
- Apply discounts to package prices before comparing.
Frequently asked questions
Can I compare grams with ounces directly?
No. Convert both quantities into the same unit first.
Why is the larger package not always better?
Its unit price may be higher, or unused contents may erase the saving.
Should I use price before or after a coupon?
Use the amount you will actually pay for each package under the same tax and discount assumptions.
