What Is a Good ROI for Amazon FBA?
ROI (Return on Investment) measures how much profit you earn relative to what you invest. For Amazon FBA, it's calculated as: ROI = (Net Profit ÷ Product Cost) × 100. A 50% ROI means you earn $0.50 for every $1 invested in inventory. Most experienced FBA sellers target a minimum ROI of 30–50%, though many successful products deliver 100%+ ROI. A higher ROI means your capital works harder, allowing you to scale faster with less cash tied up in inventory. It's especially important for wholesale and private label sellers who buy in bulk, since large purchase orders require significant upfront investment. Always calculate ROI before committing to a supplier.

Frequently Asked Questions
What ROI should I aim for on Amazon FBA?
Most FBA sellers target a minimum ROI of 30–50%. Top performers often find products with 100%+ ROI. Below 25%, you have little margin for error — PPC costs, returns, or storage fees can easily wipe out profits.
How is FBA ROI different from profit margin?
Margin is profit as a percentage of revenue. ROI is profit as a percentage of cost. A product with a 25% margin might have a 75%+ ROI if your product cost is low — both metrics matter. Use our Margin Calculator to compare.
Should advertising costs be included in the product cost?
Yes, if you're running PPC ads (Sponsored Products), your average cost-per-click and ACoS (Advertising Cost of Sale) should be factored into your profit per unit calculation for an accurate ROI picture.
