Frequently Asked Questions
Unit price is the cost per single unit of measure (e.g., per ounce, per liter, per piece). It allows you to compare products sold in different sizes or quantities on a fair basis.
Divide the total price by the number of units (size). For example, a 2-liter bottle of soda costing $3.00 has a unit price of $1.50 per liter.
Often a larger package isn't always the best value. Comparing unit prices helps you save money and avoid misleading “economy” packaging.
This calculator assumes you are comparing the same unit type. For accurate comparisons, ensure all items use the same unit (e.g., all in ounces or all in liters). If needed, you can temporarily convert one item's size manually before entering.
Not necessarily. Consider product quality, brand preference, and whether you'll use the entire quantity before it expires. The unit price is just one factor in smart shopping.
