How to calculate a unit price

To calculate the unit price, all you need to know is the total price, the number of units, and the unit price formula:

unit price = total priceno. of units\text{unit price = }\frac{\text{total price}}{\text{no. of units}}

The no. of unitsno.\ of\ units is the number of ounces, liters, or items you get by the total price paid.

The unit price formula is slightly different for comparing packages in which you only know the number of units per item (e.g., comparing a pack of soda cans vs. a pack of soda bottles) and not the total package number. In this case:

unit price = total priceno. of units per item × no. of items\text{unit price = }\frac{\text{total price}}{\text{no. of units per item × no. of items}}

For weight, it would be:

unit price = total priceweight per item × no. of items\text{unit price = }\frac{\text{total price}}{\text{weight per item × no. of items}}

And for volume:

unit price = total pricevolume per item × no. of items\text{unit price = }\frac{\text{total price}}{\text{volume per item × no. of items}}

How to use this price per unit calculator

The crucial part is selecting the correct type of calculation:

  • Weight: in this option, the no. of units to use will be the total weight of the package. The results you'll obtain will be of the type "price per ounce", "price per pound", etc.
  • Volume: the no. of units to use will be the total volume of the package. The results you'll obtain will be of the type "price per liter", "price per gallon", etc.
  • Volume: the no. of units to use will be the total number of package items. The result you'll obtain will be a "price per item".
  • Items with weight: select this option when you only know the weight of each item and not the total package weight. The results you'll obtain will be of the type "price per ounce", "price per pound", etc.
  • Items with volume: select this option when you only know the volume of each item and not the total package volume. The results you'll obtain will be of the type "price per liter", "price per gallon", etc.

Calculations per weight, volume, and no. of items use the unit price formula unit price = total priceno. of units\text{unit price = }\frac{\text{total price}}{\text{no. of units}}, while calculations of items with weight and volume use the formula unit price = total priceno. of units per item × no. of items\text{unit price = }\frac{\text{total price}}{\text{no. of units per item × no. of items}}
