China Import Profit Calculator: The Spreadsheet That Prevents Expensive Mistakes

The most common mistake new importers make isn’t choosing the wrong product. It’s not calculating the full landed cost before ordering. You spot a product on Taobao for ¥15 (roughly €2) and start imagining €15 selling price — “7.5x markup, this is going to be amazing.” Then reality arrives in layers: shipping adds €0.80 per unit, VAT adds €0.60, Etsy fees take €2.80, domestic shipping to the customer costs €3, packaging adds €0.40. Your “€2 product” actually costs €9.60 to get to a customer. Your “7.5x markup” is actually 1.56x. Still technically profitable at €5.40 per sale, but a completely different business than the 7.5x fantasy.

Margins improve with volume, and part of that is the rate you get rather than the price you pay. Fishgoo’s Premium Rewards tiers lower per-order costs as monthly volume grows.

I learned this the expensive way. My second month importing from China, I calculated margins based on product cost only — ignored shipping, ignored platform fees, ignored packaging. My “60% margin” product was actually running at 32% after all costs. Not fatal, but €280 less profit than I’d projected over 2 months. That was the month I built a proper cost spreadsheet. Every order since has been calculated to the cent before I click “buy.”

This article gives you the complete formula, worked examples across three platforms, and the decision framework that tells you whether a product is worth importing before you spend anything.

The Complete Landed Cost Formula

Every cost that stands between “product on Taobao” and “money in your account after sale”:

Profit Per Unit = Selling Price − (Sum of all 10 cost layers)

Margin % = (Profit ÷ Selling Price) × 100

Worked Example 1: Silver Ring on Etsy (France)

51.8% margin. Healthy. At 30 rings/month: €342/month profit. The zero agent fee from Fishgoo saves €0.13/unit versus a 5% agent — small per ring, but across 360 rings/year: €46.80 preserved. That’s 18 free rings worth of margin.

Worked Example 2: Desk Organizer on Amazon FBA (Germany)

33.2% margin — thinner than Etsy because Amazon takes a bigger cut (referral + FBA fulfillment). Still viable at volume: 60 units/month = €338/month. The math only works because Fishgoo‘s zero fee keeps the landed cost under 25% of the selling price. With a 5% agent fee, landed cost rises to €3.33 → margin drops to 32.7% → the buffer for unexpected costs shrinks dangerously.

Platform Fee Comparison: Same Product, Different Margins

The same product at the same selling price yields vastly different margins depending on platform. Vinted and direct sales maximize margin; Amazon FBA maximizes volume. Most successful resellers use 2-3 platforms simultaneously — Etsy for brand-building, Amazon for volume, direct for repeat customers.

The “Should I Import This?” Decision Rule

Run these numbers before your first order, not after. The 5 minutes of calculation prevent the 5 weeks of waiting-and-hoping that follows an uninformed import decision.

Break-Even Analysis: When You Get Your Money Back

Formula: Break-Even Units = Total Initial Investment ÷ Profit Per Unit

The jewelry example is striking: sell 9 rings out of 30 and you’ve recovered your entire investment. The remaining 21 rings are pure profit. This is why jewelry is the most popular Taobao resale category — the margin structure means you’re playing with house money after selling less than a third of your inventory.

FAQ

• How do I account for unsold inventory?

  Budget 10-15% of inventory as potentially unsold (styles that don’t resonate, seasonal products past their window). At Taobao’s source pricing, unsold inventory is a minor cost — 10 unsold rings at €2.50 each = €25 write-off. The same unsold inventory from a domestic wholesaler at €10/unit = €100 write-off. Low source cost makes inventory risk manageable.

• Should I charge for shipping or offer free shipping?

  “Free shipping” with the cost built into the product price converts 15-25% better than itemized shipping on most platforms. A €22 ring with free shipping outsells a €18 ring + €4 shipping — even though the buyer pays the same total. Build domestic shipping cost into your selling price and advertise “free shipping.”

• How does currency fluctuation affect margins?

  The CNY/EUR rate fluctuates 3-5% annually. At typical import volumes (€100-500/month), a 3% swing = €3-15/month variance. Not significant enough to hedge, but worth checking the rate before placing large orders. Fishgoo’s ~1.5% exchange rate margin is fixed and lower than most agents or banks.

• What’s the most overlooked cost in import profit calculations?

  Return handling cost. A returned item costs you: the product (if unsellable), the domestic shipping you already paid, the platform fees already deducted, and your time processing the return. A single return on a €22 item costs roughly €8-10 in total losses. At a 5% return rate on 30 sales/month, that’s 1.5 returns = €12-15/month in hidden cost. Build it into your baseline calculation.

• Does the zero agent fee really matter at small volumes?

  At 10 units/month from a €2 source product: 5% fee = €1/month. Trivial. At 100 units/month: €10/month = €120/year. At 500 units/month: €50/month = €600/year. The fee’s impact scales linearly with volume. Starting with Fishgoo at zero fee means you never have to switch agents as you scale — the cost advantage only grows over time.
