How to find unprofitable products on Shopify

Most stores have a few products quietly losing money on every sale. Because they often sell well, they hide in your revenue reports. Here is how to find them.

Step 1: Build the true per-unit cost

For each product, add up everything a sale actually costs: cost of goods, payment fees, shipping you do not recover, a share of returns, and allocated ad spend. This is more than the COGS field alone — see how to calculate COGS.

Step 2: Calculate net profit per product

Subtract that total cost from the selling price. Anything at or below zero is a loss on every unit. The profit margin calculator does this for a single product in seconds.

Step 3: Weight by sales volume

A product that loses $1 on 800 orders bleeds far more than one that loses $5 on 10 orders. Sort your losers by units sold — the high-volume, small-loss products are usually the biggest drain and the easiest to miss.

Step 4: Fix or cut

Reprice, pause the ads driving it, adjust shipping, or drop it. Then re-check after a week. See the full list of leak types in types of profit leaks.
