Price Comparison
Price per unit lets you compare products of different sizes to find the best deal.
Formula:
Price per Unit = Total Price / Number of Units
Examples of “units”:
- Price per ounce (oz) or gram (g) for food
- Price per sheet for paper towels
- Price per load for laundry detergent
- Price per item for multipacks
Shopping tips:
- Bigger packages are not always cheaper per unit
- Store brands often have a lower unit price than name brands
- Check unit prices on shelf labels — many stores display them
- Factor in waste: a larger pack is not a deal if it goes bad before you use it
