Unit price calculator

Compare two sizes or packs by price per unit and see which one is the better deal.

Favorite

Same unit as quantity A (ounces, grams, rolls…).

Results

B is cheaper by 19.9%

How it works

unit price = price ÷ quantity

Divide each price by its quantity to get the price of one unit (one ounce, one gram, one sheet), then compare. Use the same unit for both quantities. Bigger isn’t always cheaper, which is exactly what this check catches.

  1. Price per unit for A $4.99 ÷ 16 = $0.3119
  2. Price per unit for B $7.99 ÷ 32 = $0.2497
  3. Compare (0.3119 − 0.2497) ÷ 0.3119 × 100 = 19.9%
