Dropshipping Profit Calculator: Net Profit After All Costs & Fees
Dropshipping profit is the margin between your selling price and every cost involved in fulfilling the order: supplier cost, shipping, platform fees, payment processing, and advertising. On a $40 product with a $15 supplier cost, $3 shipping, $1.46 in payment fees, and $8 in ads, your net profit is $12.54 — a 31.4% margin. This calculator accounts for all six cost layers to reveal your true per-unit profitability.

What Dropshipping Profit Really Means
Dropshipping profit is what remains after six layers of cost are deducted from your selling price. Unlike traditional retail where you buy inventory upfront, dropshipping has lower upfront costs but thinner per-unit margins because you pay a premium for the supplier to handle fulfillment.
The most common mistake is calculating profit as "selling price minus supplier cost" — ignoring shipping, platform fees, payment processing, and ad spend. A $40 product sourced at $15 looks like $25 profit (62.5%). After all real costs, the actual profit is $12.54 (31.4%) — less than half the naive calculation.
The Complete Profit Formula
Net Profit = Selling Price − Supplier Cost − Shipping − Platform Fee − Payment Fee − Ad Spend
Where:
- Selling Price = The price your customer pays
- Supplier Cost = The wholesale price from your dropshipping supplier (AliExpress, CJ Dropshipping, Spocket, etc.)
- Shipping = Cost to ship from supplier to customer (may be included in supplier cost)
- Platform Fee = Marketplace commission if selling on Amazon (15%), eBay (13.25%), etc. Zero for Shopify/WooCommerce.
- Payment Fee = Payment processing fee: 2.9% + $0.30 (Stripe/Shopify Payments) or 3.49% + $0.49 (PayPal)
- Ad Spend = Advertising cost per sale (total ad spend ÷ number of sales)
Profit Margin = (Net Profit ÷ Selling Price) × 100
How to Use the Calculator
- Enter your Selling Price — the price customers pay
- Enter Product Cost — the supplier/dropshipping cost per unit
- Enter Shipping — shipping cost not included in the supplier price
- Enter Platform Fee — marketplace commission (0 for Shopify/WooCommerce)
- Enter Payment Fee — payment processing fee per transaction
- Enter Ad Spend — your advertising cost per sale

The result shows your net profit and profit margin. Use this to evaluate product viability before launching ads.
Worked Examples
Example 1: Shopify Store, Pet Product ($30)
| Component | Amount | % of Revenue |
|---|---|---|
| Selling Price | $30.00 | 100% |
| Supplier Cost (CJ Dropshipping) | $10.00 | 33.3% |
| Shipping | $0.00 | 0% (included) |
| Platform Fee (Shopify) | $0.00 | 0% |
| Payment Fee (2.9% + $0.30) | $1.17 | 3.9% |
| Ad Spend | $6.00 | 20.0% |
| Net Profit | $12.83 | 42.8% |
A 42.8% margin is excellent for dropshipping. The supplier cost is only 33.3% of revenue, and ads are a manageable 20%.
Example 2: Shopify Store, Home Decor ($50)
| Component | Amount | % of Revenue |
|---|---|---|
| Selling Price | $50.00 | 100% |
| Supplier Cost | $22.00 | 44.0% |
| Shipping | $4.00 | 8.0% |
| Platform Fee | $0.00 | 0% |
| Payment Fee | $1.75 | 3.5% |
| Ad Spend | $15.00 | 30.0% |
| Net Profit | $7.25 | 14.5% |
A 14.5% margin is marginal. The 30% ad spend is the problem — if CPCs rise 20%, this product loses money. Either reduce ad spend or increase the selling price.
Example 3: Amazon, Electronics Accessory ($35)
| Component | Amount | % of Revenue |
|---|---|---|
| Selling Price | $35.00 | 100% |
| Supplier Cost | $14.00 | 40.0% |
| Shipping | $0.00 | 0% (FBA) |
| Platform Fee (Amazon 15% referral) | $5.25 | 15.0% |
| Payment Fee | $0.00 | 0% (included in referral) |
| Ad Spend (Amazon PPC) | $5.00 | 14.3% |
| Net Profit | $10.75 | 30.7% |
Selling on Amazon adds 15% in referral fees but provides organic traffic, reducing ad spend. Total cost is 69.3% of revenue — similar to Shopify dropshipping but with different cost distribution.
Cost Breakdown by Platform
| Platform | Platform Fee | Payment Fee | Total Fees | Traffic Source |
|---|---|---|---|---|
| Shopify | $0 | 2.9% + $0.30 | 3–4% | Paid ads required |
| WooCommerce | $0 | 2.9% + $0.30 | 3–4% | Paid ads required |
| Amazon | 15% referral | $0 (included) | 15% | Organic + PPC |
| eBay | 13.25% + $0.35 | $0 (included) | 13–14% | Organic + promoted |
| Etsy | 6.5% + $0.20 + 3%+$0.25 | $0 (included) | 10–12% | Organic + offsite ads |
Key insight: Shopify has the lowest fees (3–4%) but requires the most ad spend (20–30%). Amazon has the highest fees (15%) but needs less ad spend (10–15%) due to organic traffic. Total costs end up similar across platforms.
Dropshipping Margin Benchmarks
| Dropshipping Model | Typical Net Margin | Supplier Cost % | Ad Spend % |
|---|---|---|---|
| Shopify + AliExpress | 15–30% | 35–45% | 20–30% |
| Shopify + CJ/Spocket | 20–35% | 30–40% | 15–25% |
| Amazon + AliExpress | 15–25% | 35–45% | 10–15% (PPC) |
| WooCommerce + AliExpress | 20–35% | 35–45% | 20–30% |
| Private label dropshipping | 30–50% | 25–35% | 15–25% |
Warning signs: Net margin below 10% means one cost increase eliminates profit. Ad spend above 30% means your business is ad-dependent and fragile. Supplier cost above 50% means your markup is too low.
How to Improve Dropshipping Margins
| Strategy | Margin Impact | Difficulty |
|---|---|---|
| Increase selling price | +5–15% | Easy (if demand supports) |
| Negotiate lower supplier cost | +3–8% | Medium |
| Switch to cheaper supplier | +5–10% | Medium (quality risk) |
| Improve ad ROAS (target 4x+) | +5–15% | Hard (requires testing) |
| Bundle products (higher AOV) | +5–10% | Medium |
| Move to private label | +15–25% | Hard (upfront investment) |
| Reduce returns (better descriptions) | +2–5% | Easy |
The highest-impact improvements: Raising price by $5 on a $40 product with $15 cost improves margin from 31% to 41% — a 10-point jump. Improving ad ROAS from 2x to 4x halves ad cost per sale, potentially adding 10–15 margin points.
