Enter your product price and quantity on the left and click Calculate to see the unit cost breakdown.
The formula is simple: Total Cost ÷ Number of Units = Cost Per Unit. For example, if you pay $30 for a box of 60 items, each item costs $0.50.
When you shop, products come in different sizes and pack counts. The one with the lowest total price is not always the best deal. Calculating cost per unit shows you the true value of each option. You can also use our price per unit calculator to quickly compare products by their per-unit price.
Adding shipping, tax, and handling fees gives you the real cost per unit — not just the shelf price. This is especially useful when comparing online stores or buying in bulk.
