Freight math

Freight Cost Calculator

The headline rate per CBM is never the real rate — fixed charges see to that.

Freight total = volume × rate per CBM + fixed charges. An 8 CBM LCL shipment at $145 per CBM with $650 of fixed fees — documentation, handling, destination delivery — costs $1,810, an effective $226 per CBM, 56% above the headline rate. Fixed charges are why small shipments always cost more per cube than quotes suggest, and why the effective rate falls as shipments grow. Enter your volume, rate and fixed charges to see the true bill and the rate you are actually paying.

Worked examples

Small LCL shipment

Shipment volume 8
Rate per CBM $145.00
Fixed charges $650.00
Total freight cost $1,810.00
Effective rate per CBM $226.25

The $145 quote becomes an effective $226/CBM once fixed fees land.

Larger consolidation

Shipment volume 20
Rate per CBM $145.00
Fixed charges $650.00
Total freight cost $3,550.00
Effective rate per CBM $177.50

Same fixed fees over 20 CBM: the effective rate falls to $178/CBM.

Frequently asked questions

What are the fixed charges on a freight quote?

The per-shipment lines that do not scale with volume: documentation and bill-of-lading fees, origin and destination terminal handling, customs clearance, delivery order and trucking to your door. On LCL shipments they commonly run $400–$900 total, which is why they dominate the economics of small shipments.

At what volume should I switch from LCL to a full container?

Usually around 13–15 CBM. LCL is billed per CBM with chunky fixed fees, while a 20ft container is one flat price for up to ~28 usable CBM. When your LCL total approaches the FCL quote — often near the mid-teens of CBM — the container wins, and it also ships faster with less handling damage.

Why is my effective rate so much higher than the quoted rate?

Because the quoted ocean rate is only one line of the bill. Fixed charges spread over few cubic meters inflate the blended rate: $650 of fees over 8 CBM adds $81 per CBM on its own. Always compare forwarders on the all-in total for your exact volume, never on the headline per-CBM rate.

How stable are freight rates when I am planning ahead?

Not very — spot ocean rates can double or halve within a quarter on demand swings, capacity changes and disruptions. Treat any rate older than a few weeks as stale: re-quote before each shipment, budget with a cushion above the current spot rate, and consider a forwarder contract rate once your volume is steady.
