These three calculations help you compare value more clearly when products come in different sizes or pack counts.

Worked examples

Example 1: If 12 items cost 8.99, the price per unit is 8.99 ÷ 12 = 0.7492 per unit.
Example 2: Product A costs 8 for 10 units (0.80 per unit) and product B costs 10 for 14 units (0.7143 per unit), so product B has the lower unit price.
Example 3: If one unit costs 0.75 and you need 24 units, the total cost is 0.75 × 24 = 18.
