Landed Cost Calculator Guide: Which Calculator Should You Use?

Three Calculators, One Question: What Will This Really Cost?

I've spent the better part of a decade watching importers price shipments wrong. Not because they can't do math, but because they're answering three different questions with one tool. How much does this shipment cost to land? How much duty and tax will customs actually charge? And what price do I need to sell at to make a profit? Landed Cost Hub now has a dedicated calculator for each of those questions, and this guide walks through when to use which one, with real numbers from shipments I've priced.

The trigger for splitting them came from a client in 2024. He imported 2,000 LED strip lights from Shenzhen to Los Angeles. He used the main landed cost calculator, got a total of $11,340, and priced the product at $14.99 with a 'healthy margin'. Three months later he was losing money on every unit. The duty was fine, but he had ignored the Section 301 tariff on electronics and priced at 2.2x landed cost instead of 3x. The general calculator showed him the cost. A duty-focused calculator would have shown him the 25% tariff. A pricing calculator would have told him $14.99 was suicide. He needed all three, and he needed them before he ordered, not after.

Calculator 1: The Landed Cost Calculator (Total Shipment Cost)

The main calculator on the homepage answers: what does this shipment cost from supplier door to my door? It adds up product cost, sea/air/express freight, insurance, customs duty, VAT, clearance fees, and inland freight, then divides by units to give cost per unit. This is the one to use when you are comparing suppliers, choosing a shipping method, or deciding whether a product is viable at all.

A real example from my files: 1,200 ceramic mugs from Yiwu to Rotterdam, LCL sea freight. Product cost $4,320, freight $680, insurance $25, duty at 12% on CIF $145, VAT at 21% on (CIF + duty) $1,094, clearance $85, trucking $140. Total $6,489, or $5.41 per unit. If you only look at the FOB price of $3.60, you are 50% off your real cost. That gap is exactly why the general calculator exists -- it forces you to see the $2,169 of freight, tax, and fees hiding under the product price. Use it first, always, before any pricing decision.

Calculator 2: The Duty Calculator (Customs Duties by HS Code)

The duty calculator focuses on one slice of the picture: what customs will actually charge you. Enter an HS code or pick a product category and it shows the base duty rate for your origin-destination pair, VAT/GST, and Section 301 tariffs where they apply (China to US, for example). This is the tool to use when you are checking whether a product is viable at a specific duty rate, comparing HS code classifications, or budgeting for a specific tariff line.

The difference matters more than most people think. Take the same product classed under two HS codes: 9403 (furniture) vs 9401 (seats). For China to US, 9403.20 carries 0% duty under normal MFN rates while a similar steel product under 9401 can attract additional tariffs. Get the code wrong and your '0% duty' product suddenly costs 25% more. I've seen importers lose a whole margin to a one-digit HS error. The duty calculator exists because in 2026, with Section 301, IEEPA tariffs, and the EU's July 2025 VAT changes, the tax layer is where most of the surprises live.

Calculator 3: The Pricing Calculator (Minimum Retail Price)

The pricing calculator answers the question that actually pays the bills: what do I need to sell this at to hit my target margin? It takes the landed cost per unit, applies your target gross margin, and shows the minimum retail price. It also has a currency buffer field -- I recommend 2-3% -- to absorb FX swings between quote and payment, which is how importers quietly lose margin without noticing.

How to use it: run the landed cost calculator first to get your true cost per unit. Then switch to the pricing calculator, enter your target margin (Amazon and eBay sellers should use 45-55% gross margin before marketplace fees, because Amazon takes 15-25% and PPC eats another 10-20%), and read the minimum retail price. In my LED strip example: cost per unit $5.67, target margin 55%, 3% FX buffer -> minimum retail price $13.00. His $14.99 was barely above break-even; at $19.99 he would have had a real business. The pricing calculator turns 'I think this is profitable' into 'I know this is profitable'.

Which One Should You Use? A Decision Rule

If you are comparing suppliers or choosing freight: use the landed cost calculator. If you are checking whether a specific product works at its real duty rate: use the duty calculator. If you are setting a selling price or reviewing your margin: use the pricing calculator. If you are doing any of this seriously, use all three in order -- cost first, duty second, price third -- because each one feeds the next.

The three-calculator split is not a gimmick. In my experience pricing imports, the single most common failure is jumping straight to a selling price from a FOB quote. That skips both the duty layer and the margin math. The people who use all three tools in sequence -- and I have dozens of clients who now do -- rarely have margin surprises. The tools are free, they work in 8 languages, and each one takes under a minute. The cost of not using them is a margin you discover six months late.
