How it works
How it works
Price per unit is the price divided by the quantity. Use the same unit for every option, such as ounces, sheets or pounds. The lowest result is the cheapest per unit.
A bigger pack only saves money if you will use all of it, so think about waste and storage as well.
FAQ
About this calculator
How do I compare prices per unit?
Divide the price by the quantity for each option, using the same unit. The lowest result is the best price per unit.
Is the lowest unit price always the best deal?
Not always. A bigger pack saves money only if you use all of it before it spoils or you no longer need it.
What units can I use?
Any, as long as they match across options, such as ounces, sheets, pounds, feet or count.
Is anything saved?
No. The math runs in your browser and nothing you enter is sent to us.
