Understanding Your Freight Costs
Calculating the cost of shipping containers internationally involves more than just looking up a base price. The final invoice from a freight forwarder or carrier is typically a composition of the base ocean freight, variable surcharges, and fixed handling fees. This Container Rates Calculator helps importers and exporters estimate the total landed cost of their shipment.
Key Components of Container Shipping Rates
Base Ocean Freight: This is the core price to move the container from Port A to Port B. It fluctuates based on supply and demand, seasonality, and trade lane capacity.
BAF (Bunker Adjustment Factor): A floating surcharge that compensates carriers for fluctuating fuel (bunker oil) prices. This is usually calculated as a percentage of the base freight or a fixed amount per TEU (Twenty-foot Equivalent Unit).
CAF (Currency Adjustment Factor): Applied to trade lanes where currency exchange rates fluctuate significantly against the carrier's base currency (usually USD).
THC (Terminal Handling Charges): Fees charged by the port terminals for loading and unloading containers from the vessel and moving them within the terminal yard.
Why Include Cargo Insurance?
Many first-time shippers overlook insurance, assuming the carrier is liable for damage. However, international maritime law (Hague-Visby Rules) significantly limits carrier liability. Calculating insurance based on your Cargo Value is essential for a realistic shipping budget. A typical premium might range from 0.3% to 0.5% of the commercial invoice value + freight cost.
Optimizing Your Container Loads
Freight rates are generally quoted per container (FCL – Full Container Load). Whether you ship a 20-foot container that is 50% full or 100% full, the base freight and THC remain largely the same. To minimize the cost per unit of goods, always aim to maximize the utilization of the container volume.

// 4. Perform Calculations
// Total Base Freight = Number of Containers * Base Rate
var totalBaseFreight = numContainers * baseRate;
// Calculate Surcharges (Percentage of Total Base Freight)
var bafCost = totalBaseFreight * (bafPct / 100);
var cafCost = totalBaseFreight * (cafPct / 100);
var totalSurcharges = bafCost + cafCost;
// Calculate Terminal Handling (Per Container)
var totalThc = numContainers * thc;
// Calculate Insurance (Percentage of Cargo Value)
var insuranceCost = cargoValue * (insuranceRate / 100);
// Calculate Grand Total
// Base + Surcharges + THC + Docs (usually fixed per BL/Shipment) + Insurance
var grandTotal = totalBaseFreight + totalSurcharges + totalThc + docFees + insuranceCost;
// 5. Update UI
// Format numbers to currency
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
