How to calculate the net weight?

Using scales and measuring equipment

To calculate net weight, you can weigh the product alone using a weighing scale. Alternatively, you can weigh the product with its packaging, container, and dunnage, then weigh those components separately – a figure known as tare weight – and subtract it from the gross weight. Follow these steps to obtain your net weight:

Weigh the product while still in its container or packaging to get the gross weight.
Remove the product from the packaging, then weigh the packaging to get the tare weight.
Subtract the tare weight from the gross weight to get the net weight. In short, the mathematical formula for net weight is:

Net weight = Gross weight – Tare weight

Net weight = Quantity of products * Weight of each product

Net weight is especially important in the food and beverage industry, as it’s commonly printed on product packaging and is necessary for calculating serving sizes. It also impacts airway bills and the goods you can transport at once. Finally, shipping companies need it to calculate certain fees, such as those based on packaging weight or total weight, using a net weight calculator.

Common mistakes to avoid

The following errors and inaccuracies should be avoided to prevent risks during the weighing process. This will optimize the shipping process, reducing time and expenses.

Incorrect tare weight: Ensure that your tare weight is accurate. If you’re using an average tare weight, make sure it’s representative of the specific containers you’re using.
Weight fluctuations: Be mindful of weight fluctuations due to temperature, humidity, or product settling. If possible, weigh items under consistent conditions.
Measurement errors: Use calibrated scales and ensure accurate readings. Double-check measurements, especially for large or valuable items.
Packaging variations: If packaging varies significantly in weight, consider using a sample of packages to determine an average tare weight.
Incorrect units: Ensure you’re using consistent units of measurement (e.g., grams, kilograms, pounds) throughout your calculations.
Calculation errors: Double-check your calculations, especially when dealing with multiple items or complex scenarios.
Ignoring accessory weight: If accessories like pallets or dunnage exist, include them in the gross weight calculation.
Neglecting environmental factors: In some cases, environmental factors like temperature and humidity can affect the weight of products. Consider these factors when necessary.

By avoiding these common mistakes, you can ensure accurate net weight calculation and avoid potential shipping, inventory management, and product pricing issues.

What does gross weight mean?

Gross weight is the weight of your goods plus the packaging used to transport them. For example, the gross weight of a liquid includes the weight of the liquid plus the bottle or can containing it. If products are canned and placed in a cardboard box, the weight of the cans and the cardboard box contributes to the gross weight.

Gross weight includes net weight, tare weight, and the weight of the carrier. The gross weight of water transport is your product’s tare weight and net weight. However, gross weight for road transport is the weight of the products being transported plus the weight of the vehicle.

Add your product’s net weight to the container’s weight to calculate the gross weight. The calculation of gross weight can vary between different modes of transportation. Here are some examples:

Air freight: The calculation of gross weight includes the aircraft’s weight, people on the aircraft, and fuel.
Road transport: The gross weight is equal to the weight of the truck plus the weight of the body and the net weight.
Sea freight: Add the net weight and the weight of the container to obtain the gross weight.

Mathematically, the formula for calculating the gross weight is:

Gross weight = Tare weight + Net weight + Other accessories

You can also calculate the gross weight from the net weight. Once you have the net weight, add the weight of the empty container and other accessories to the weight of your product to get the gross weight.

What is tare weight?

Tare weight, also known as unladen weight, is the weight of an empty container or vehicle. Tare weight can be either the actual or average tare weight. The actual tare weight is the actual weight of the container without any pallets or packaging. The average tare weight is the total tare weight of several containers divided by the number of containers.

Tare weight is crucial for calculating the gross weight or net weight. For example, you will get the gross weight if you add the tare weight to the net weight. You will get the net weight by subtracting the tare weight from the gross weight. The formulas for calculating tare weight are:

Tare weight = Gross weight – Net weight

You can find the tare weight printed on intermodal containers. These weights typically vary depending on the size of the container.
