How to Compare Product Prices
Compute the unit price for each product, then see which is lower. The percentage difference tells you how much more expensive the pricier option is.
Formula
Unit Price = Total Price / Quantity
Difference % = Unit A - Unit B

- 03Product B is cheaper per unit
- 04Difference = |$0.6650 - $0.5490| / $0.6650 x 100 = 17.4%
Perguntas Frequentes
What if the products have different quality?
Unit price only measures cost per unit, not quality. Consider quality alongside price when making a decision.
Should I compare by weight or by count?
Use whatever measure is most meaningful. For food, weight (ounces) is often best. For packaged items like trash bags, count works better.
Does this work for comparing different brands?
Yes, as long as you are comparing equivalent products. A unit price comparison between a name brand and store brand reveals the cost premium.
