How to Calculate Shopify Profit Margins: SKU Costs, Fees & Profit Calculator

Shopify sellers often overlook the true cost per SKU. The platform's fee structure includes a monthly subscription, transaction fees, and payment processing fees. For example, a basic Shopify plan costs $29/month, plus a 2% transaction fee and 2.9% + 30¢ payment processing fee per sale. If you're selling an SKU for $20, your total fees could be around $1.68 per sale. But that's not all. You also need to factor in the cost of goods sold (COGS), shipping, and any app subscriptions. For instance, if your COGS is $8 and shipping is $3, your total cost per SKU is $12.68, leaving you with a profit of $7.32. But wait, there's more. If you're using apps like GoMarginify, you can get a true net profit per SKU by accounting for all these costs and fees.

A common mistake is not tracking the cost per SKU accurately. Many sellers use an average cost, which can lead to miscalculations. For example, if you're selling multiple SKUs with different costs, using an average cost can skew your profit margin analysis. To avoid this, track the cost per SKU individually. This will give you a more accurate picture of your profit margins.

The profit margin percentage formula is straightforward: (Profit / Revenue) x 100. For example, if you're selling an SKU for $20 and your total cost is $12.68, your profit is $7.32. Your profit margin percentage would be (7.32 / 20) x 100 = 36.6%. However, this is a simplified example. In reality, you need to factor in all costs, including platform fees, shipping, and any other expenses. For instance, if you're running ads, you need to include the ad spend in your cost calculation. If you're spending $2 on ads per sale, your total cost per SKU would be $14.68, reducing your profit to $5.32 and your profit margin percentage to 26.6%.

Another common mistake is not updating your cost calculations regularly. Prices and fees can change, so it's important to review your costs regularly. For example, if Shopify increases its transaction fees, your profit margins will decrease. To stay on top of this, review your costs monthly and adjust your pricing accordingly.

One common mistake is not accounting for all costs. Many sellers only consider the cost of goods sold and ignore other expenses like platform fees, shipping, and ads. This can lead to an overestimation of profit margins. For example, if you're selling an SKU for $20 and your COGS is $8, you might think your profit margin is 60%. But if you're not accounting for other costs, your actual profit margin could be much lower. To avoid this, make sure to include all costs in your calculations.

Another mistake is not tracking profit margins by SKU. Many sellers look at their overall profit margins and miss out on valuable insights. For example, you might have one SKU that's dragging down your profit margins, but if you're not tracking profit margins by SKU, you won't know which one it is. To avoid this, track profit margins by SKU. This will help you identify which SKUs are performing well and which ones need improvement.

One way to improve your profit margins is to negotiate better deals with your suppliers. For example, if you're buying your products from Costco, you might be able to negotiate a lower price if you're buying in bulk. This can help reduce your COGS and increase your profit margins. Another way is to optimize your shipping strategy. For example, if you're shipping products internationally, you might be able to find a cheaper shipping method. This can help reduce your shipping costs and increase your profit margins.

You can also improve your profit margins by increasing your selling price. However, this needs to be done carefully. If you increase your price too much, you might lose customers. To avoid this, test different price points and see how they affect your sales. For example, you might find that increasing your price by 5% doesn't affect your sales, but increasing it by 10% does. In this case, you can increase your price by 5% and keep your customers happy.

A profit calculator can help you track your Shopify profits accurately. For example, GoMarginify connects to Shopify and provides daily profit reports via email and IM. This can help you stay on top of your profits and make informed decisions. Another way to use a profit calculator is to track your profits over time. For example, you might notice that your profits are decreasing every month. This could be due to increasing costs or decreasing sales. By tracking your profits over time, you can identify trends and make adjustments accordingly.

Another way to use a profit calculator is to compare your profits across different channels. For example, if you're selling on multiple platforms like Amazon and Shopify, you can use a profit calculator to compare your profits on each platform. This can help you identify which platform is more profitable and adjust your strategy accordingly.
