ROI (Return on Investment) measures how much profit you make relative to your total investment. It's calculated as (Profit / Total Investment) × 100%.
A good ROI for Amazon FBA is typically 20-50% or higher. However, this depends on your business goals, risk tolerance, and market conditions.
Profit margin is profit as a percentage of revenue, while ROI is profit as a percentage of total investment. ROI considers all costs including initial inventory investment.
Payback period is the time it takes to recover your initial investment. It's calculated by dividing total investment by monthly profit.
Both are important. ROI helps you understand return on capital, while profit margin shows operational efficiency. Successful sellers monitor both metrics.
