Landed Cost & Tariff Estimate

Customs duties and import tariffs depend on the precise Harmonized System (HS / HTS) tariff classification code, origin country, port drayage fees, and customs broker charges. Verify classifications with a licensed customs broker.

Understanding Landed Cost & Pricing

Landed cost represents the complete, true expense required to manufacture, transport, clear through customs, insure, inspect, and package a physical product until it sits inside your fulfillment warehouse ready for dispatch to customers.

How the Engine Operates

Enter your supplier unit FOB cost, international freight per unit, import customs tariff percentage, packaging cost, payment gateway fee schedule, and desired profit margin. The calculator computes the total landed cost per unit and solves for the required retail selling price that protects your target margin after payment processing deductions.

Mathematical Formula & Variables

Customs duty is calculated on the FOB unit cost. Total landed cost combines FOB cost, freight, customs duty, and packaging. The recommended retail price factors in both payment processing fees and your target profit margin.

Customs Duty Cost = FOB Unit Cost × (Tariff % / 100)
Total Landed Cost per Unit = FOB Cost + Freight/Unit + Customs Duty + Packaging

Recommended Retail Price = (Total Landed Cost + Gateway Fixed Fee) / (1 - (Gateway Rate% / 100) - (Target Margin% / 100))
Break-Even Retail Price = (Total Landed Cost + Gateway Fixed Fee) / (1 - (Gateway Rate% / 100))

Step-by-Step Worked Example

Example: You import a product manufactured overseas with a $15.00 FOB price. Ocean freight is $3.00 per unit, customs tariff is 6.0%, and custom packaging is $1.50. You target a 55% gross profit margin and expect standard 2.9% + $0.30 payment processing fees. 1. Customs Duty = $15.00 × 0.06 = $0.90 per unit. 2. Total Landed Cost = $15.00 + $3.00 + $0.90 + $1.50 = $20.40 per unit. 3. Compute pricing denominator: 1 - 0.029 (gateway) - 0.55 (margin) = 0.421. 4. Recommended Retail Price = ($20.40 + $0.30) / 0.421 = $20.70 / 0.421 = $49.17. Verification Check: • Selling Price: $49.17 • Landed Cost: $20.40 • Gateway Fee: ($49.17 × 0.029) + $0.30 = $1.73 • Net Gross Profit: $49.17 - $20.40 - $1.73 = $27.04 (exactly 55.0% of $49.17).

When to Use This Tool

  • When evaluating quotes from overseas or domestic manufacturing suppliers.
  • When budgeting container-load sea freight versus air freight shipments.
  • When setting MSRP catalog prices for wholesale distribution or direct-to-consumer stores.
  • When auditing landed cost variances between product batches.

Common Pitfalls to Avoid

  • Pricing retail products based solely on the supplier factory invoice (FOB) while forgetting freight and customs duties.
  • Omitting payment processing fees when setting retail prices, which quietly erodes 3% of your profit margin on every checkout.
  • Failing to account for port drayage, customs broker filing fees, or warehouse receiving charges in unit economics.

Practical Strategic Recommendations

  • Obtain verified Harmonized System (HS / HTS) tariff classification codes from your customs broker before issuing manufacturing purchase orders.
  • Compare Full Container Load (FCL) versus Less than Container Load (LCL) freight rates to optimize per-unit shipping expenses.
  • Include a 3% to 5% buffer in your landed cost calculations to account for potential freight surcharges and exchange rate shifts.

Frequently Asked Questions

What is FOB in manufacturing contracts?

FOB stands for Free On Board. It means the seller covers manufacturing and transport to the origin shipping port, but the buyer is responsible for ocean/air freight, marine insurance, import customs duties, and domestic delivery.

Why should payment gateway fees be included in landed cost pricing?

Payment processors charge fees on the full checkout transaction total. Omitting gateway fees from your retail pricing calculation means you absorb those fees directly from your net margin.

How do customs tariffs affect retail pricing?

Customs duties increase your baseline landed cost. If a tariff raises your unit cost by $2.00, keeping your margin steady requires raising the retail price by $4.00 or more depending on your margin target.
