Most dropshipping margin calculations look like this:
Selling price (€30) − Product cost (€10) − Shipping (€4) = €16 profit
This calculation is missing approximately 40% of real costs. Stores that scale on AliExpress eventually hit a wall not because they suddenly become bad at marketing, but because the hidden costs catch up with the revenue. Here is the full breakdown of where €100 of dropshipping revenue actually goes when you ship from AliExpress.
What gets factored in (the visible 60%)
Every dropshipper knows about these:
- Product cost — what the supplier charges you for the item
- Shipping cost — what AliExpress charges to ship the package
- Ad spend — Meta or TikTok cost to acquire the customer
- Payment processing — 2.4-2.9% on Shopify Payments
For a typical €30 product with €10 product cost, €4 shipping, €8 ad spend, and 2.9% processing (€0.87), the visible cost is €22.87 out of €30. That leaves €7.13 in apparent profit on a 24% gross margin.
This is the number you see in your Shopify dashboard. It is also the number that leads thousands of dropshippers to wonder why their bank account does not reflect their "profit."
What gets missed (the hidden 40%)
These costs do not show up in your daily metrics but they consistently destroy actual profit:
1. Dispute costs — the biggest leak
When a customer disputes a charge on AliExpress fulfilled orders, you typically lose the full order value. Not just the refund — the ad spend that brought them in, the product cost, the shipping, and the foregone profit on that sale.
Industry data shows AliExpress-fulfilled stores running 5-10% dispute rates depending on niche and shipping speed. At 5% dispute rate on 200 orders/month at €30 AOV, that is €300 in disputes alone. The combined loss including ad spend and processing: €450-600/month evaporates here.
Stores with proper fulfillment partners running 1-2% dispute rates. The gap is significant.
2. Chargeback fees
A dispute that escalates to a chargeback costs €15-25 in processor fees on top of the refund. At 200 orders/month with a 5% dispute rate where half escalate, that is 5 chargebacks × €20 = €100/month in fees alone.
3. Customer service time
At 200 orders/month with a 5% dispute rate plus general inquiries, you are handling 15-20 customer service interactions per week. Even at €15/hour for your own time (or a VA's), this is €60-80/week or €240-320/month in support cost that never appears in your Shopify reports.
4. Ad creative testing waste
Not all ad spend converts. Stores that test creatives properly spend 30-50% of their total ad budget on non-performing variations. This is not waste — it is the cost of finding what works — but it must be included in the true customer acquisition cost.
If your converting ads cost €8 to acquire a customer, your blended CAC is actually closer to €12-15 once you include testing budget.
5. App and tool stack
The average Shopify dropshipping store runs 8-12 apps: tracking, reviews, upsells, email, support, analytics. Realistic monthly spend: €200-500/month in subscriptions that rarely appear in margin calculations.
6. Payment processor reserves
If your dispute rate exceeds 1%, Shopify Payments may hold a rolling reserve of 5-10% of your sales for 60-180 days. This is not lost money but it is cash flow locked up exactly when scaling stores need it most.
The real math at scale
For a store doing €6,000/month in revenue (200 orders at €30 AOV):
| Category | Cost | Notes |
|---|---|---|
| Product cost | €2,000 | 200 × €10 |
| AliExpress shipping | €800 | 200 × €4 |
| Ad spend (blended) | €2,400 | 200 × €12 (incl testing) |
| Payment processing | €174 | 2.9% of €6,000 |
| Dispute losses | €450 | 5% × full order value |
| Chargeback fees | €100 | 5 × €20 |
| Support time | €240 | 15 hrs × €16 |
| App stack | €350 | Tracking, reviews, etc. |
| Total costs | €6,514 | |
| Net | -€514 |
This is what dropshippers actually see when they look at their bank account at the end of the month: revenue went up, profit went down or disappeared. The gap between "Shopify dashboard profit" and "money in the bank" is where most stores die.
What fixes this
The single highest-leverage fix is reducing dispute rate, because disputes compound across multiple cost categories. A dispute does not just cost you the refund — it costs the ad spend, the product, the shipping, the chargeback fee, the support time, and the rolling reserve hit.
Shipping speed is the primary driver of dispute rates. Stores moving from AliExpress (18-25 day delivery) to a proper fulfillment service (6-10 day delivery) typically see dispute rates drop from 5-7% to 1-2% within 60 days.
At 200 orders/month, that single change converts a €514 monthly loss into a €700-1000 monthly profit. The economics flip from negative to positive because one root cause (slow shipping) was generating costs across six categories.
What to do this week
If you are running AliExpress fulfillment and have not done this calculation honestly:
- Pull your last 90 days of Shopify orders
- Calculate your actual dispute and chargeback rate (not "estimated" — actual)
- Multiply your dispute count by your average order value to get the real dispute cost
- Add your support time at honest hourly rate
- Add your app stack monthly
- Compare to your Shopify "profit" number
The gap between those two numbers is your hidden cost stack. For most dropshippers it is €500-2000/month they did not know they were losing.
The fix is not "find cheaper ads" or "negotiate harder with suppliers." The fix is closing the cost categories that compound through dispute rates.
