Dropshipping Profit Calculator

Per-sale profit margin for dropshipping after all costs

Calculate dropshipping profit per sale by entering supplier cost, platform fees, ad spend, and shipping to see margin and net profit.

What this tool does

This calculator estimates the profit generated from a single dropshipping transaction. It works by taking your selling price and subtracting all direct costs: what you pay the supplier, the platform fee (calculated as a percentage of selling price), the advertising cost attributed to that sale, and the shipping expense. The result shows both the profit amount in your currency and the profit margin as a percentage of the selling price. The ad cost per sale and supplier cost are typically the largest drivers of the final profit figure. This tool is useful for evaluating whether individual product listings are financially viable, or for comparing profitability across different items in your catalog. The calculator models a simplified transaction and assumes all costs are known and fixed; it does not account for variable operational expenses, inventory management costs, returns, or refunds.

Quick answer: with the default values, the result is $12.50 (Profit Per Sale). Adjust the values below for your own figures.

Dropshipping Profit Structure

Dropshipping business model: buyer orders through store, store forwards order to supplier, supplier ships directly to buyer. Store captures difference between selling price and supplier cost minus platform and advertising costs. Thin margins typical — 5-15% net margin on typical products, higher on well-differentiated ones and often lower or negative without clear differentiation. Calculator quantifies specific per-sale economics to evaluate product viability before scaling.

Typical Dropshipping Costs

Supplier cost is often 20-40% of selling price for goods sourced through marketplaces such as AliExpress. Platform fees vary by marketplace, plan, and region: hosted-store platforms typically charge a monthly plan fee plus per-transaction payment processing, while marketplaces such as Amazon and eBay charge category-banded selling fees (commonly in the region of 8-15%). Ad cost per sale is often 5-20 for broad social ads on commodity products and 2-8 for well-targeted niche products. Shipping runs 2-15 depending on supplier and destination. Combined costs often reach 60-80% of selling price, leaving 20-40% gross margin before paying yourself; net margin is often 5-15% for established dropshippers.

Worked Example for Typical Product

Selling price 50, supplier 15, platform 15% (7.50), ad 10, shipping 5. Total costs 37.50, profit per sale 12.50, gross margin 25% (before owner time, returns, and refunds). At this margin, 100 sales a month works out to about 1,250 profit before the owner's own time. Raising ad cost to 20 per sale cuts profit to 2.50. Lower supplier costs or premium positioning raise the margin, so product selection and differentiation shape the economics.

What the Calculator Does Not Model

Customer service time and cost. Returns and refunds (typical 5-15% of sales). Payment processing chargebacks. Platform compliance issues (account suspensions). Time cost of store management. Specific niche market competition. Brand building value beyond single-sale economics. Scale benefits at higher volumes. Tax implications of business income. The calculator shows per-sale math; business viability also depends on scale and risk factors outside this per-sale model.

Dropshipping Viability

The calculator shows baseline per-sale economics. Profitability in dropshipping is commonly associated with product selection (unique, higher-margin items that are not widely available), marketing and ad efficiency (lower customer-acquisition cost), returns management, and scale. Common reasons cited for stores not reaching profitability include commodity product selection, high acquisition costs, and returns eroding margins. The calculator helps compare product and price combinations before committing to testing.

Example Scenario

Dropshipping at $50 with $15 supplier cost produces $12.50 per sale.

Sources & Methodology

Methodology

The calculator computes per-sale profit by subtracting all costs from the selling price. It applies the platform fee as a percentage of the selling price, then adds the supplier cost, ad cost per sale, and shipping cost to derive total outgoings. Profit equals selling price minus these combined costs. The profit margin is then expressed as a percentage of the selling price. The model assumes a constant platform fee percentage and fixed per-sale costs, treating each transaction independently. It does not account for variable costs, bulk discounts, refunds, returns, payment processing variations, inventory holding costs, or seasonal demand fluctuations. Results represent a single-transaction snapshot and are not a projection of performance across multiple sales.

Frequently Asked Questions

What margin is viable?
Net margins vary by product. Typical stores often land in the 5-15% range after all costs, where there is little room to absorb a cost increase. Product differentiation or a distinct niche can lift margins into the 15-25% range, and stronger differentiation toward 25-40%; above 40% usually involves strong branding and exclusive supplier relationships. Generic commodity products tend to sit at the lower end, which is harder to scale.
How much can I earn dropshipping?
Earnings vary widely and are not something a calculator can predict. Income depends on product selection, marketing efficiency, order volume, and how costs like returns and advertising evolve over time. Many stores take a sustained period of testing before covering their costs, and some do not reach profitability at all. This tool models the economics of a single sale rather than any income projection.
What's realistic ad cost per sale?
Ad cost per sale is often higher early on (frequently cited around 15-30 while a store is still learning its audience), lower once campaigns are optimised (around 5-15), and lower still for niche or branded products (around 2-8). When ad cost runs above roughly 20% of the selling price, it leaves little margin behind. Advertising efficiency is one of the larger levers on dropshipping economics.
What about returns?
Returns commonly run 5-15% of sales, with the dropshipper often bearing return shipping and customer-service cost, which reduces the effective margin. Return handling commonly consumes a portion of gross margin. This calculator does not model returns, so the profit-per-sale figure sits above the net once returns are accounted for.
