You make money dropshipping by selling products online at a markup without ever holding inventory. When a customer places an order on your store, you purchase the item from a third-party supplier who ships it directly to the buyer. Your profit is the difference between what the customer paid you and what you paid the supplier, minus advertising, platform fees, and other overhead. Net profit margins in dropshipping typically fall between 5% and 20%, meaning a store doing $10,000 in monthly revenue might keep $500 to $2,000 after all expenses.
Where the Profit Actually Comes From
Dropshipping margins work in two layers. The first is your gross margin: the gap between your retail price and the supplier’s wholesale cost. On average, dropshippers see gross margins around 60% to 75%, meaning for every $100 in sales, roughly $60 to $70 remains after product costs. That sounds generous, but the second layer is where most of the money disappears. Advertising, payment processing fees, shipping surcharges, refunds, and platform subscriptions all eat into that gross margin, leaving a net profit that’s much thinner.
A useful rule of thumb: if you’re not clearing at least $30 per sale after product cost and shipping, running paid ads will likely put you at a loss. This is why product selection matters so much. Selling a $15 phone case with a $2 margin leaves almost nothing for advertising, while a $70 pet accessory with a $35 margin gives you room to spend on customer acquisition and still profit.
Choosing Products and Suppliers
Your supplier determines your product quality, shipping speed, and ultimately your reputation. Domestic suppliers that ship from U.S.-based warehouses typically deliver in two to five business days, which meets most customers’ expectations. Platforms like Spocket, Modalyst, Zendrop, and Trendsi let you filter for domestic warehouses so you can prioritize fast delivery. Slower shipping from overseas suppliers can work for unique or niche products, but expect higher refund rates and more customer complaints.
When evaluating a product, look at three things: the margin after supplier cost and shipping, how easily you can demonstrate the product’s value in a short video or image, and whether there’s genuine demand you can reach through advertising. Products that solve a specific problem or trigger an impulse purchase tend to convert better than generic commodities. You’ll also want to order samples before listing anything. Selling a product you’ve never seen or touched is a fast way to get blindsided by quality issues.
Setting Up Your Store
Most dropshippers sell through their own online store, through a marketplace like Amazon, or both. The cost structure differs significantly between the two approaches.
Running your own store on a platform like Shopify costs $39 to $399 per month depending on the plan, plus roughly 2.9% and $0.30 per transaction for payment processing. You control the branding, the customer experience, and the pricing, but you’re responsible for driving every visitor through your own marketing.
Selling on Amazon gives you access to a massive built-in audience. The Professional seller plan runs $39.99 per month, but Amazon charges a referral fee of 8% to 15% on every sale depending on the product category. Those referral fees are substantially higher than standard payment processing costs, which compresses your margins. The trade-off is that you don’t need to spend as much on advertising to get eyeballs on your listings.
Many sellers start with their own store to learn the fundamentals of marketing and product selection, then expand to Amazon once they’ve identified winning products.
How Advertising Drives (and Eats) Revenue
Paid advertising is the engine behind most dropshipping stores, and it’s also the biggest variable cost. Customer acquisition cost, meaning what you spend in ads to land one paying customer, varies wildly by product category. In arts and entertainment, it can be as low as $21 per customer. In health and beauty or fashion, expect closer to $127 to $129. Electronics can run as high as $377 per customer.
These numbers explain why product margins matter so much. If your average order earns $40 in gross profit but it costs $129 in ads to acquire that customer, you’re losing money on every sale. Profitable dropshippers either find ways to lower their acquisition costs (through better ad creative, organic content, or email marketing to repeat buyers) or sell higher-margin products that can absorb the ad spend.
Most beginners start with Meta (Facebook and Instagram) ads or TikTok ads because both platforms let you target specific interests and demographics with relatively small daily budgets. A common testing approach is to spend $20 to $50 per day on a handful of ad sets, measure which products and creatives generate sales, then scale spending on the winners while cutting the losers. Expect to lose money during this testing phase. The goal is to find a product and ad combination that produces a positive return, then pour more budget into it.
The Math Behind a Profitable Store
Here’s what a simplified monthly breakdown might look like for a store generating $8,000 in revenue:
- Product costs (30% of revenue): $2,400
- Advertising (35% of revenue): $2,800
- Platform subscription: $39
- Payment processing (roughly 3%): $240
- Shipping and handling: $400
- Refunds and chargebacks: $200
- Net profit: $1,921 (about 24%)
That’s an optimistic scenario. Many stores, especially in the first few months, run at a loss while the owner tests products and refines their advertising. The stores that reach consistent profitability usually do so after testing dozens of products and spending hundreds or thousands of dollars on ads that didn’t convert. Aiming for at least a 10% net margin is a reasonable baseline, though 20% or higher is where the business starts to feel worthwhile for the time invested.
Sales Tax and Legal Basics
Dropshipping is a real business, and most states require you to collect sales tax once you hit certain revenue thresholds. The most common trigger is $100,000 or more in gross receipts from sales to customers in a given state during a lookback period. Some states previously used a 200-transaction threshold as an alternative trigger, but that standard is being phased out in certain jurisdictions. If you’re selling on Amazon or another major marketplace, the platform typically collects and remits sales tax on your behalf. If you’re running your own store, you’ll need to register for sales tax permits in states where you’ve crossed the threshold and use tax automation software to calculate and collect the correct rates.
Beyond sales tax, you’ll want to register your business formally. Most dropshippers operate as a sole proprietorship initially, though forming an LLC provides liability protection that separates your personal assets from business debts. You’ll also need a basic bookkeeping system to track revenue, costs, and ad spend so you can calculate your actual profit rather than guessing.
What Separates Stores That Profit From Those That Don’t
The dropshippers who make real money tend to share a few habits. They test products methodically rather than falling in love with one item and spending their entire budget trying to make it work. They track their numbers obsessively, knowing their cost per click, conversion rate, and net margin on every product. They reinvest early profits into better ad creative and faster shipping options rather than pulling cash out immediately.
Most importantly, they treat customer experience as a competitive advantage. Fast shipping from domestic suppliers, responsive customer service, and hassle-free returns lead to repeat purchases and positive reviews, both of which lower the cost of acquiring future customers. A returning customer who buys again without clicking an ad is pure margin, and building that kind of loyalty is what turns a side hustle into a sustainable business.
