Understanding Your Profit Metrics in Japan
It is not just about revenue; it is about what you keep. This calculator breaks down three critical metrics:
- Net Profit: The actual cash value you earn after all costs and Amazon fees are deducted.
- Profit Margin: The percentage of the selling price that is profit. High margins mean a safer business.
- ROI (Return on Investment): This shows how efficiently your capital is working. A 100% ROI means you double your money on every sale.
- Don’t Forget Amazon Points: In Japan, offering Amazon Points (usually 1%) is standard practice to boost sales. This calculator does not deduct points automatically, so you should treat points as an additional “marketing cost” and subtract them from your Net Profit.
What is a Good Profit Margin for FBA?
For most Private Label sellers, a healthy Net Profit Margin is between 25% and 30%. If your calculation shows a margin below 15% (marked in red), your business is at risk.
💡 Pro Tip: Need Higher Margins?
Don’t settle for low-profit products. The secret to 30%+ margins is finding low-competition niches.
