Shopify Cost of Goods Sold: Definition, Formula & How to Track
- Helps you set the right price: Knowing your actual costs ensures that your pricing strategy covers expenses and maximizes profit.
- Allows you to accurately calculate your profit margins: Your gross profit is calculated as revenue minus COGS. By dividing this by total revenue, you get the gross profit margin, a key metric for evaluating business performance.
- Supports data-driven decisions: Understanding your most profitable products allows you to focus on scaling the right items and discontinuing those that don’t contribute to your bottom line.
- Beginning inventory is the value of inventory at the start of the period.
- Purchases during period is the cost of new stock or materials bought.
- Ending inventory is the value of unsold inventory at the end of the period.
- Go to Shopify Admin → Click on Analytics → Select Reports.
- Under Finances, you’ll find the Profitability Report (if enabled).
- If COGS isn’t visible, manually input your costs in the Cost Per Item field under each product in the Shopify dashboard.
