Unit Price Calculator
Calculate the cost per unit, ounce, gram, or piece to compare product value across different package sizes.
Run tool
This unit price calculator helps you compare package values by finding the exact cost per single unit of measure. Enter the total item price, the total quantity included in the package, and your preferred unit label such as ounces, pounds, grams, fluid ounces, or count. When you submit the values, the tool calculates the rate by dividing the entered price by the quantity. If the price field is left empty or set to a negative number, the calculator automatically treats it as zero. If the quantity field is left empty or set to zero or below, the tool defaults the quantity to one to prevent calculation errors. The calculated unit rate rounds to four decimal places internally and presents a clear formatted summary showing the cost rounded to two decimal places alongside your custom unit label. This makes grocery shopping, bulk purchasing, and package size comparisons simple and direct.
Instructions
- Enter the total package price into the price field.
- Enter the total amount or volume into the quantity field.
- Type the unit of measurement, such as oz, lb, g, or count, into the unit field.
- Review the calculated rate per unit displayed in the result area.
Examples
- A 16 oz box of cereal costs $4.00. Entering price 4, quantity 16, and unit oz shows a unit rate of $0.25 per oz.
- A 3-pack of paper towels costs $6.99. Entering price 6.99, quantity 3, and unit roll shows a unit rate of $2.33 per roll.
