Frequently Asked Questions

What is a good ROI for Amazon FBA?

A good ROI for Amazon FBA is 100% or higher (doubling your money). Many successful sellers target 50-100% ROI minimum. Our calculator helps you determine if your products meet this threshold.

How do I calculate Amazon ROI?

ROI = ((Revenue - Total Costs) / Total Costs) × 100. For Amazon, include product cost, shipping, Amazon fees, and advertising in your costs. Our calculator automates this calculation.

What ROI should I aim for in product sourcing?

When sourcing products, aim for at least 50% ROI after all fees. Products with 100%+ ROI are excellent. Avoid products under 30% ROI as advertising costs can eliminate profits.

How does inventory turnover affect ROI?

Faster inventory turnover means you can reinvest profits sooner, compounding your returns. A product with 50% ROI that sells monthly can outperform 100% ROI selling quarterly.
