Enter the number of family members, the average space required per person, and the number of days worth of food to be stored into the calculator to determine the freezer capacity.

Freezer Capacity Formula

The following formula is used to calculate the freezer capacity.

FC = N * S * D

Variables:

  • FC is the freezer capacity (liters or cubic feet)
  • N is the number of family members
  • S is the average space required per person (liters or cubic feet)
  • D is the number of days worth of food to be stored

To calculate the freezer capacity, multiply the number of family members by the average space required per person, then multiply the result by the number of days worth of food to be stored. This will give you the total freezer capacity required for your household.

What is a Freezer Capacity?

Freezer capacity refers to the amount of space available inside a freezer for storing food items. It is usually measured in liters or cubic feet. The capacity determines how much food and other items you can store in the freezer at a time. Larger families or those who like to buy in bulk or batch cook might require a freezer with a larger capacity, while smaller households may find a smaller capacity sufficient.

How to Calculate Freezer Capacity?

The following steps outline how to calculate the Freezer Capacity.


  1. First, determine the number of family members (N).
  2. Next, determine the average space required per person (S) in liters or cubic feet.
  3. Next, determine the number of days worth of food to be stored (D).
  4. Finally, use the formula FC = N * S * D to calculate the Freezer Capacity.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

number of family members (N) = 4

average space required per person (S) = 50 liters

number of days worth of food to be stored (D) = 7
