Dropshipping Margin Calculator

About the Dropshipping Margin Calculator

Dropshipping seems simple: sell a product for more than the supplier charges and pocket the difference. But real-world margins are squeezed by platform fees, payment processing, advertising costs, and refund rates. Many dropshippers discover their actual margin is far thinner than expected.

This calculator accounts for all the cost layers in a dropshipping business: supplier cost plus shipping, marketplace or website platform fees, payment processing fees, advertising cost per sale, and an estimated refund rate. The result is your true per-order profit and margin.

Use This calculator before sourcing any product to verify the math works. If the margin is too thin, you'll know to find a cheaper supplier, raise the price, reduce ad costs, or pass on the product entirely.

When This Page Helps

Dropshipping margins can be deceptively thin. A product that looks profitable at 3× markup may barely break even after ads, fees, and refunds. This calculator reveals your true bottom-line profit per order, helping you avoid products that waste time and money.

How to Use the Inputs

1. Enter your selling price for the product.
2. Enter the supplier cost including their shipping charge.
3. Enter the platform fee rate (Shopify transaction fee, marketplace fee, etc.).
4. Enter the payment processing fee rate and per-transaction fee.
5. Enter your average advertising cost per sale (total ad spend / orders).
6. Enter your estimated refund rate.
7. View your net profit per order and effective margin.

Tips & Best Practices

• Target at least 30% margin after all costs — below 20%, one bad month of ads or refunds wipes profits.
• AliExpress ePacket shipping (7–15 days) is cheapest but slow; faster options (5–7 days) improve reviews.
• Source domestically (US-based suppliers, CJdropshipping, Zendrop) for faster shipping, even at slightly higher cost.
• Reduce ad cost per sale by improving product pages, using UGC ads, and retargeting warm audiences.
• Account for chargebacks (1–2% of orders) which cost $15–25 each on top of the lost sale.
• Products priced $25–60 tend to have the best balance of impulse buying and margin room for dropshipping.

Dropshipping Cost Breakdown

A typical dropshipping order has five cost layers: (1) Supplier + shipping (35‒50% of revenue), (2) Advertising (15‒30%), (3) Platform fees (2‒15%), (4) Payment processing (3–4%), (5) Refunds and chargebacks (2‒10%). Together, these consume 60‒90% of the selling price, leaving 10‒40% profit.

Product Selection for Margin

Protect margins by choosing products that are: lightweight (cheap to ship), non-fragile (low returns), not easily compared (avoid commodity products with many identical listings), and have perceived value above their cost (unique designs, problem-solving products). Products priced $30–60 offer the best margin-to-conversion balance.

Scaling and Margin Erosion

As you scale dropshipping, ad costs per sale tend to increase (audience saturation), refund rates may rise (broader audience = less targeted), and competition intensifies. Plan for 10–20% margin erosion at scale compared to initial test results.

Frequently Asked Questions

• What is a good dropshipping margin?

  A healthy dropshipping margin is 30–50% after all costs. Top-performing products can achieve 40–60%. Below 20% is risky because small increases in ad costs or refund rates can eliminate profit. Products with under 15% margin should generally be avoided.

• What costs do dropshippers forget?

  Common overlooked costs: payment processing fees ($0.30 + 2.9% per order), chargebacks ($15–25 each), customer service time, refund shipping costs, Shopify/app subscriptions, VAT/sales tax obligations, and product replacement for quality issues. These can total 5–10% of revenue.

• How much should I spend on ads per sale?

  Ad cost per sale depends on the product price and niche. For $30–50 products, $8–15 per sale is common on Facebook/TikTok. Your cost per acquisition (CPA) should be less than 30% of the selling price. If CPA exceeds this, your margins are likely too thin.

• Should I dropship on Shopify or Amazon?

  Shopify has lower per-order fees (2% + payment processing) but requires you to drive traffic via ads. Amazon has higher fees (15% referral + fulfillment) but provides built-in traffic. Shopify works for branded/unique products; Amazon works for products with existing search demand.

• How do refunds affect dropshipping margins?

  You refund the selling price but can't recover the supplier cost (most suppliers don't accept returns easily). A 10% refund rate means 10% of your revenue is lost while you still paid the supplier. This effectively reduces your margin by the refund rate multiplied by the profit percentage.

• Can I dropship on Amazon?

  Yes, but Amazon requires the product ship with your branding (not the supplier's). Direct AliExpress-to-customer dropshipping violates Amazon's policy. Use a US-based 3PL or Amazon-compliant supplier. FBM (Fulfillment by Merchant) is the standard for dropshipped products on Amazon.
