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 / max(Unit A, Unit B) x 100

Example Calculation

Product A: 6-pack for $3.99 vs Product B: 10-pack for $5.49.

  1. 01Product A unit price = $3.99 / 6 = $0.6650
  2. 02Product B unit price = $5.49 / 10 = $0.5490
  3. 03Product B is cheaper per unit
  4. 04Difference = |$0.6650 - $0.5490| / $0.6650 x 100 = 17.4%
