How to Calculate Volumetric Weight for Courier: If you’re planning to send a courier package, knowing the volumetric weight is important. Couriers charge based on either the actual weight or the volumetric weight—whichever is higher. This ensures that bulky but lightweight packages don’t take up excess space without appropriate charges. Understanding how to calculate volumetric weight helps in estimating shipping costs accurately and avoiding surprises.

What is Volumetric Weight?
Volumetric weight, also called dimensional weight, is a pricing technique used by courier companies to charge for the space a package occupies rather than just its actual weight. A large, lightweight package can take up more space in a truck or airplane, so couriers use this method to balance charges fairly.
Formula for Calculating Volumetric Weight
The formula varies slightly depending on whether you’re using domestic or international shipping, and different courier services may have different divisors. However, the basic formula remains:
Volumetric Weight (kg) = (Length × Width × Height) / Divisor
- For domestic shipments: Many couriers use a divisor of 5000 (Length × Width × Height in cm ÷ 5000).
- For international shipments: The divisor is often 6000 (Length × Width × Height in cm ÷ 6000).
Step-by-Step Example
Let’s say you have a box with these dimensions:
- Length: 50 cm
- Width: 40 cm
- Height: 30 cm
For domestic shipping:
Volumetric weight = (50 × 40 × 30) ÷ 5000 = 12 kg
For international shipping:
Volumetric weight = (50 × 40 × 30) ÷ 6000 = 10 kg
Now, compare this with the actual weight of your package. If your package weighs 8 kg, but the volumetric weight is 12 kg, the courier will charge based on 12 kg since it is the higher value.
Why Does Volumetric Weight Matter?
- Cost Estimation: Knowing how to calculate volumetric weight allows you to estimate shipping costs before booking a courier service.
- Optimized Packaging: If your package is large but lightweight, try to use compact packing to reduce volumetric weight and save on costs.
- Avoiding Surprises: Some people assume couriers charge based only on weight, but a bulky package may cost more than expected.
Tips to Reduce Shipping Costs
- Use Compact Packaging: Reduce empty spaces inside the package by using smaller boxes.
- Choose the Right Courier: Some courier services have different divisors; compare to find the most cost-effective option.
- Check Courier Policies: Some companies use different formulas for air vs. ground shipping. Always confirm before shipping.
Final Thoughts
Understanding how to calculate volumetric weight helps you make informed shipping decisions, avoid unexpected costs, and optimize your packaging. Whether you’re shipping domestically or internationally, always compare the actual weight and volumetric weight to determine your shipping charges. If you send packages frequently, consider investing in a digital scale and measuring tape to calculate the weight in advance.
