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
计算示例
Product A: 6-pack for $3.99 vs Product B: 10-pack for $5.49.
- Product A unit price = $3.99 / 6 = $0.6650
- Product B unit price = $5.49 / 10 = $0.5490
- Product B is cheaper per unit
- Difference = |$0.6650 - $0.5490| / $0.6650 x 100 = 17.4%
