Stop the Cost Explosion: CoLoCa Amid Rising Freight Rates
Rising freight rates are weighing on margins and calculations across the entire supply chain. For forwarders, exporters and logisticians the right response is clear: not only negotiate prices, but use available loading capacity more efficiently. CoLoCa, the Container Loading Calculator, helps by calculating volumes precisely and maximizing container utilization — thereby securing the profitability of your transports.
Current Freight Rate Developments and the Consequences
Freight rates have been volatile for several months and are generally at a higher level than before. Causes include bottlenecks in the global transport infrastructure, increased demand and rising operating costs. For shippers this means:
- Higher unit costs per container or per m³
- Larger fluctuations in offer calculations
- Declining margins at unchanged sales or delivery prices
In this environment every percentage point saved on transport costs becomes important. The catchphrase is: maximize utilization.
Why Maximum Utilization Is the Rescue
The volumetric utilization of a container directly affects cost per unit. A poorly utilized container increases effective freight rates per shipped unit — especially at higher container prices. Through optimized packing concepts and the right choice of container you can often reduce the number of containers needed. That lowers total costs, emissions and administrative effort.
CoLoCa supports you by:
- calculating freight volume precisely (dimension-based or by direct volume),
- automatically determining utilization for six standard container types (20ft/40ft/45ft, Standard & High Cube),
- displaying remaining space in m³ and ft³ and color-coding utilization (Green/Yellow/Red/Black).
This information forms the basis for a fact-based decision: which container type is economical? Which cargo allocation saves containers and thus money?
Example: 15% Cost Savings Despite Price Increase
Assumption: your total volume is 500 m³. You use 40ft High Cube (76.36 m³). For 500 m³ you get:
- Required containers (naive): ceil(500 / 76.36) = 7 containers
Scenario A — freight rate rises:
- Old freight rate: €1,000 / container
- New freight rate: €1,200 / container (+20%)
- Costs without optimization: 7 × €1,200 = €8,400
Scenario B — optimization using a better packing strategy and possibly switching to 45ft High Cube (84.16 m³):
- Required containers after optimization: 6 containers
- Costs after optimization: 6 × €1,200 = €7,200
Result: Compared to unoptimized shipping at increased freight rates you save €1,200 — that is about 14.3% (rounded: ~15%) less cost. The optimization not only offsets the price jump, it also makes you more competitive.
Important: the exact savings depend on your volumes, pack dimensions and the correct container choice. CoLoCa provides the baseline numbers with which you can perform these calculations reliably.
Practical Tips for Utilization Optimization
- Capture volume precisely
- Use dimension-based calculation (H × W × D × quantity) or direct volume entries. Accurate numbers prevent over- or undercapacity.
- Compare container types
- 20ft Standard (33.17 m³), 20ft High Cube (37.38 m³)
- 40ft Standard (67.69 m³), 40ft High Cube (76.36 m³)
- 45ft Standard (74.63 m³), 45ft High Cube (84.16 m³)
- Aim for a target utilization range
- Optimal: 70–90% (Yellow) — good balance of use and buffer for load securing.
- Avoid: over 90% (Red) without reserve or >100% (Black) — increased risk of damage and handling issues.
- Standardize piece and pallet dimensions
- Uniform pallet sizes (e.g. 120×80×100 cm) simplify planning and increase packing density.
- Consolidate positions and use shares
- Combine cargo items sensibly to close gaps in the container. With share links (e.g., CoLoCa-Share) calculations and packing lists can be quickly shared with partners.
- Simulate regularly
- Calculate different scenarios (different container type, slightly different quantities) — this way you quickly identify the most economical variant.
Long-term Strategies for Better Profitability
- Periodic volume reviews: monthly analyses show whether packing strategies have become established.
- Training operational teams: staff who load and pack should know the utilization targets.
- Standardization of packaging: uniform dimensions reduce gaps and empty volume.
- Combined logistics solutions: cross-docking or consolidation at the transshipment point reduce overcapacity.
Conclusion
Rising freight rates require active control of container utilization. Those who capture their volumes precisely, choose the right containers and optimize packing strategies can save significant costs despite higher freight rates — often around 10–20% compared to unoptimized shipping. Tools like CoLoCa provide the necessary numeric values (m³, utilization percentages, remaining capacity) and make the optimization potential visible.
