Ocean Freight Surcharges Calculator

How to Use This Tool

Enter your base ocean freight rate (what the carrier quotes before surcharges) and any applicable surcharges from your freight forwarder's quote. Common surcharges include BAF (fuel), CAF (currency), PCS (port congestion), PSS (peak season), and THC (terminal handling). Select your container type for accurate record-keeping. Click Calculate to see the total landed cost per container and the percentage that surcharges add to your base rate.

Formula and Logic

Total Landed Cost = Base Freight + Surcharges

Where:
BAF Amount = Base Freight × (BAF % / 100)
CAF Amount = Base Freight × (CAF % / 100)
PSS Amount = Base Freight × (PSS % / 100)
ERS Amount = Base Freight × (ERS % / 100)
PCS and THC are fixed amounts per container.

All percentage-based surcharges are calculated on the base freight only, not cumulatively. This matches industry practice where surcharges are applied to the base ocean freight rate.

Practical Notes

Pricing Strategy: If surcharges exceed 30% of your base freight, consider renegotiating contracts or exploring alternative routes/ports. During peak season (July–October), PSS can jump to 20-50%—factor this into your Q4 pricing.

Margin Thresholds: For e-commerce sellers, keep total freight cost (including surcharges) under 15-20% of your product's landed value to maintain healthy margins. Use this calculator to test different scenarios before committing to suppliers.

Trade Terms: Under Incoterms® 2020, surcharges are typically the buyer's responsibility under FCA, FOB, and CFR terms. Confirm with your forwarder which surcharges are included in their "all-in" rate versus itemized.

Market Benchmarks: BAF usually ranges 10-25% depending on fuel prices. CAF is often 1-3% but can spike with currency volatility. PCS varies wildly by port—$100-$800/container in congested hubs like Shanghai or Los Angeles.

Why This Tool Is Useful

Freight forwarders often quote a low base rate but add surcharges later, eroding your profit. This calculator reveals the true cost upfront, helping you compare quotes accurately. It's especially valuable for small businesses without dedicated logistics staff who need to budget shipments and set product prices that cover all shipping costs. Use it to negotiate better terms by showing you understand the full cost structure.

Frequently Asked Questions

Why do surcharges change every month?

BAF fluctuates with bunker fuel prices; CAF adjusts for currency exchange rate changes between USD and the carrier's accounting currency (often EUR or CNY). Carriers publish these adjustments monthly in their tariffs.

Are surcharges negotiable?

Yes, especially for high-volume shippers. BAF and CAF are often non-negotiable as they're tied to external indices, but PCS, PSS, and THC can be discounted or waived in exchange for volume commitments. Always ask for an "all-in" rate.

What's the difference between PCS and THC?

PCS (Port Congestion Surcharge) is a carrier-imposed fee when ports are backlogged. THC (Terminal Handling Charge) is a standard fee for loading/unloading at the terminal. Both are usually fixed per container, but PCS is temporary while THC is permanent.

Additional Guidance

Always request a detailed surcharge breakdown in your quote. Some forwarders bundle BAF/CAF into an "ocean freight adjustment" line item—ask them to split it for transparency. For LCL shipments, surcharges are typically pro-rated per cubic meter. When comparing quotes, ensure all calculators use the same base (e.g., per 20ft container) and that THC includes both origin and destination port fees. Finally, track surcharge trends over 6-12 months to predict seasonal spikes and plan inventory accordingly.
