# How Do I Calculate Amazon Profit Margins?

To calculate your Amazon profit margin, subtract all costs — product cost, referral fees, FBA fees, ad spend, and returns — from your selling price, then divide that number by your selling price. Most healthy Amazon brands target a net margin of 15 to 25 percent. Ignoring any one cost layer is where sellers get into trouble.

## The Full Breakdown

Here are the core costs you need to account for:

- **Product/COGS:** Your landed cost per unit, including manufacturing and freight.
- **Amazon Referral Fee:** Typically 8–15% of the selling price, depending on category.
- **FBA Fulfillment Fees:** Charged per unit based on size and weight tiers.
- **Advertising (PPC):** Your total ad spend divided across units sold — this is frequently underestimated.
- **Returns & Refunds:** Category-dependent but must be modeled in.
- **Storage Fees:** Monthly and long-term storage, especially critical for slow-moving SKUs.

## The Formula

**Net Margin % = (Selling Price − All Costs) ÷ Selling Price × 100**

For example, if you sell a product for $40 and your total costs are $30, your net margin is 25%. Simple math — but the discipline is in capturing every cost accurately before you scale.

## The Most Common Mistake

Most sellers undercount advertising spend and returns. As your ad budget grows, untracked TACOS (Total Advertising Cost of Sales) can silently compress margins even as top-line revenue climbs. Revenue is vanity — margin is what builds a sellable, sustainable brand.
