CBM Calculator Guide: How to Calculate CBM for Sea Freight & Shipping Costs | Inex Solutions

When importing products through sea freight, one of the most important factors determining your shipping cost is CBM (Cubic Meter).
Whether you're using a 20 ft container, 40 ft container, or consolidated LCL shipping, understanding CBM helps you avoid overpaying and plan your shipment more efficiently.

At Inex Solutions, our CBM Calculator makes it simple for importers to calculate shipping volume accurately — ensuring transparency in freight charges.

Let’s break it down.

1️⃣ What is CBM (Cubic Meter) in Shipping?

CBM stands for Cubic Meter, a unit used to measure the volume of your cargo.
Shipping companies use CBM to calculate freight charges, especially for LCL (Less than Container Load) sea shipments.

CBM Formula:

CBM = Length (m) × Width (m) × Height (m)

If your measurements are in cm:
CBM = (L × W × H) / 1,000,000

Using a cbm calculator makes this easier and avoids manual errors.

2️⃣ Why CBM Matters in Sea Freight

Shipping lines charge based on:

• Cargo weight

• Cargo volume (CBM)

Whichever is higher becomes the billing factor.

This is called:
👉 Chargeable Weight vs. Chargeable Volume

So even if your cargo is light, a big volume increases the shipping cost.
This is why importers use a cbm shipping calculator before finalizing orders.

3️⃣ How to Calculate CBM for Sea Freight (Examples)

Example 1: Single Box

Dimensions:

• 60 cm × 50 cm × 40 cm

CBM = (60 × 50 × 40) / 1,000,000 = 0.12 CBM

Example 2: Multiple Boxes

Let’s say you have 10 boxes, each 0.12 CBM:

Total CBM = 10 × 0.12 = 1.2 CBM

This is your actual volume for LCL shipping.

4️⃣ What Is the Cost of Shipping 1 CBM?

The 1 cubic meter shipping cost depends on:

• Origin port (China, Vietnam, Thailand, etc.)

• Destination port in India

• Season & demand

• Type of cargo

• Forwarder charges

Typically, shipping 1 CBM may range between ₹3,000 – ₹9,000, depending on market conditions.

Using a CBM freight calculator helps importers estimate the total shipping cost in advance.

5️⃣ CBM Capacity of Containers (20 ft & 40 ft)

If you are shipping FCL (Full Container Load), here’s what you need to know:

20 Feet Container CBM

• Actual CBM capacity: 33 CBM

• Safe usable CBM: 28–30 CBM
  (Always leave space for packaging and palletizing.)

40 Feet Container CBM

• Actual capacity: 67 CBM

• Usable CBM: 55–58 CBM

A 20 feet container cbm calculator helps you determine how much cargo will fit and whether you should choose LCL or FCL.

6️⃣ How Inex Solutions' CBM Calculator Helps Importers

Our CBM Shipping Calculator is designed to:

• Instantly calculate CBM for any package size

• Support multiple boxes/products

• Help you choose between LCL vs FCL

• Estimate total sea freight cost

• Plan container utilization (20 ft & 40 ft)

This eliminates guesswork and ensures accurate freight budgeting.

7️⃣ Tips to Reduce CBM and Save Freight Cost

Here’s how to optimize your shipment volume:

1. Use compact packaging to reduce unused space.

2. Avoid unnecessarily large boxes for light items.

3. Consolidate shipments from multiple suppliers.

4. Use vacuum packing for textiles, soft goods, and clothing.

5. Plan shipments with Inex Solutions to maximize container usage.

These small adjustments can significantly lower your CBM freight cost.

8️⃣ CBM vs Weight — Which Matters More?

For Sea Freight LCL:
📌 Freight is charged on CBM (volume)

For Air Freight:
📌 Freight is based on volumetric weight or physical weight, whichever is higher.

For Full Containers (FCL):
📌 Cost is fixed per container (volume doesn’t change the price)
