Profit & margins
Revenue vs profit: what is the difference?
Revenue is the total money your store brings in from sales. Profit is what's left after you subtract the costs of making those sales and running the business. Revenue measures how much you sell and profit measures how much you keep, so a store can grow revenue quickly while its profit shrinks.
Revenue vs profit: definitions
Revenue (also called sales or turnover) is what customers pay you. Online stores usually track two versions:
- Gross sales: the total value of orders before discounts and refunds.
- Net revenue: gross sales minus discounts, returns and refunds. This is the figure profit is calculated from.
Profit is revenue minus costs. There are three main levels, each subtracting more:
Gross profit = Revenue − COGS Operating profit = Gross profit − Operating expenses Net profit = Revenue − COGS − Operating expenses − Interest − Taxes
When people say "profit" without a qualifier, they usually mean net profit: what the business actually keeps.
Comparison table
| Revenue | Profit | |
|---|---|---|
| What it measures | Money coming in from sales | Money left after costs |
| Where it appears | Top line of the P&L | Further down the P&L (gross, operating, net) |
| Grows when | You sell more or charge more | Sales grow faster than costs, or costs fall |
| Can be negative? | No | Yes, a loss |
| Tells you | Demand and scale | Whether the business works |
| Easy to inflate with | Discounts, heavy ad spend | Hard to inflate for long |
Example: one month for a Shopify store
Worked example: from revenue to profitExample numbers
| Line | Amount |
|---|---|
| Gross sales | $52,000 |
| Discounts, returns and refunds | −$5,000 |
| Net revenue | $47,000 |
| Cost of goods sold | −$19,000 |
| Gross profit | $28,000 |
| Operating expenses (ads, shipping, fees, apps, staff, other) | −$21,400 |
| Operating profit | $6,600 |
| Interest and taxes | −$1,500 |
| Net profit | $5,100 |
Out of $52,000 of orders, the store keeps $5,100, or 10.9% of net revenue.
High revenue, low profit: how it happens
Revenue is the easiest number to grow, and the easiest to grow badly. Here's the same store pushing ad spend to grow sales by 50%:
Worked example: revenue up 50%, profit downExample numbers
| Before | After | |
|---|---|---|
| Net revenue | $47,000 | $70,500 |
| COGS (same margin) | $19,000 | $28,500 |
| Gross profit | $28,000 | $42,000 |
| Ad spend | $8,000 | $20,000 |
| Shipping and fees (scale with sales) | $5,600 | $8,400 |
| Apps, staff, other (fixed) | $7,800 | $7,800 |
| Operating profit | $6,600 | $5,800 |
Revenue rose 50%, but the extra sales cost so much in ads that operating profit fell by about 12%.
The usual causes of this pattern:
- Ad spend growing faster than sales. Each extra sale gets more expensive to win. The Ad Profit Leak Score shows whether your ads cover their cost after margin.
- Discount-driven growth. Sales jump during promotions, but each one earns less.
- A shift toward low-margin products. Best-sellers aren't always the most profitable products.
- Rising fulfillment costs as order volume grows, especially with free shipping.
How to grow profit, not just revenue
- Track gross margin and operating profit monthly, alongside revenue.
- Raise average order value, so each order carries more profit. The AOV uplift calculator shows what a higher AOV is worth.
- Judge ads on profit, not ROAS alone. The guide to ROAS shows how to set targets from your margin.
- Price from a target margin, not a markup. See how to calculate selling price.
- Keep fixed costs in check as you grow. The guide to overhead costs covers what to watch.

FAQ
Is revenue the same as profit?
No. Revenue is the money customers pay you for what you sell. Profit is what's left after you subtract the costs of making those sales and running the business. A store can have high revenue and no profit at all.
Which is more important, revenue or profit?
Profit, over any meaningful period. Revenue shows demand and scale, but only profit pays for growth, debt and your own income. Early-stage stores sometimes accept low profit to grow revenue, but that only works if the path to profit is clear.
Can a business have revenue but no profit?
Yes, and many online stores do. If product costs, shipping, ad spend and overheads add up to more than revenue, the store makes a loss however much it sells.
Is profit the same as cash?
No. A profitable store can run short of cash, for example after buying a large batch of inventory. Profit is measured on the P&L; cash depends on when money actually comes in and goes out.
