Enter the gross weight and the tare weight into the calculator to determine the net weight of an item. The net weight is the weight of the item without any packaging or container.

Net Weight Formula

The following formula is used to calculate the net weight:

NW = GW - TW

Variables:

  • NW is the net weight of the item
  • GW is the gross weight (total weight including item and packaging/container)
  • TW is the tare weight (weight of the packaging/container)

To calculate the net weight, subtract the tare weight from the gross weight.

What is Net Weight?

Net weight is the weight of the actual product without any additional packaging, containers, or any other materials that are not part of the product itself. It is a crucial measurement in shipping, logistics, and sales to ensure customers are charged accurately for the product they are purchasing.

How to Calculate Net Weight?

The following steps outline how to calculate the net weight:


  1. First, determine the gross weight (GW) of the item including its packaging/container.
  2. Next, determine the tare weight (TW) which is the weight of the packaging/container alone.
  3. Use the formula NW = GW – TW to calculate the net weight (NW).
  4. Finally, calculate the net weight of the item.
  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.

Gross Weight (GW) = 250 units

Tare Weight (TW) = 20 units

By applying the formula, the Net Weight (NW) would be calculated as follows:

NW = GW – TW = 250 – 20 = 230 units
