Unit Price

Unit price tells you how much one single item or one unit of measure costs. It is found by dividing the total cost by the number of units, which turns a whole-bundle price into a fair "per unit" comparison. This works because if a price covers several equal units, splitting the total evenly across them gives the cost of just one.

Use this when comparing grocery deals, checking which package is better value, or finding the cost of one item when only a bulk price is given. It is especially useful when products come in different sizes, like bottles, boxes, kilograms, or meters.

• Dividing quantity by total price instead of total price by quantity
• Forgetting to include the correct unit, such as per kg, per item, or per mL
• Comparing products without making sure they use the same unit size
