What Is a Unit Price?
The unit price is the cost of a single unit of a product.
Formula:
Unit price = Total price ÷ Quantity
Unit price is the standard metric used by shoppers, retailers, and analysts to compare the true value of products that come in different sizes or package quantities. It removes the confusion caused by bulk discounts or varying package sizes.
