How it works
price per ounce = total price ÷ size in ouncescompare two packs the same way; the lower price per ounce wins
- total price
- what the package costs
- size in ounces
- the pack size, in weight ounces or fluid ounces
- price per ounce
- the unit price you compare across sizes
Keep the ounces consistent. A weight in ounces (oz) and a volume in fluid ounces (fl oz) are different measures, so only compare a weight against a weight, or a volume against a volume.
Frequently asked questions
How do I calculate price per ounce?
Divide the total price by the number of ounces in the package. A $6.49 pack of 16 oz is about $0.41 per ounce.
Which package is the better value?
Work out the price per ounce for each, then pick the lower one. The bigger pack is not always cheaper per ounce.
What is $6.49 for 16 oz per ounce?
About $0.41 per ounce, since 6.49 divided by 16 is roughly 0.406.
Can I use this for fluid ounces?
Yes. Enter the size in fluid ounces to get a price per fluid ounce, just do not mix weight ounces and fluid ounces in the same comparison.
