There is no single “good” ROI for Amazon wholesale. Most sellers set their own minimum based on how fast the product sells, how risky it is and how much cash they have. What matters is that you calculate it the same way every time and stick to your minimum.
Quick answer: ROI = profit ÷ product cost. Profit margin = profit ÷ selling price. Wholesale ROI is usually lower than arbitrage because you buy in bulk and reorder the same products, so fast-selling, low-risk products can work at a lower ROI than slow or risky ones.
How to Calculate ROI on Amazon Wholesale
- Start with the selling price (the Buy Box price).
- Subtract Amazon’s referral fee and FBA fulfillment fee.
- Subtract inbound shipping, prep and any storage you expect.
- Subtract your product cost. What is left is profit.
- Divide profit by product cost and multiply by 100.
Example: price $20.00, Amazon fees $7.00, shipping and prep $0.75, product cost $7.00. Profit = $20.00 − $7.00 − $0.75 − $7.00 = $5.25. ROI = $5.25 ÷ $7.00 = 75%. Margin = $5.25 ÷ $20.00 = 26%.

ROI vs Profit Margin on Amazon FBA
| ROI | Profit margin | |
|---|---|---|
| Formula | Profit ÷ cost | Profit ÷ selling price |
| Answers | How hard is my money working? | How much of each sale do I keep? |
| Best for | Choosing what to buy | Comparing products and pricing |
Both use the same profit number. ROI is the one most wholesale sellers use to decide what to order, because it shows the return on the cash you put in.
What Is a Good Profit Margin for Amazon Wholesale?
Margins vary a lot by category and price. One 2026 industry article puts realistic product margins for Amazon wholesale at around 15–35% (Ecom Circles). Treat ranges like this as a reference point, not a target. Your own numbers matter more.
How to Set Your Minimum ROI
Ask three questions about each product:
- How fast does it sell? A product that sells through in a few weeks can work at a lower ROI, because you can reinvest the cash many times a year.
- How risky is it? Many sellers, an unstable price, expiration dates or Amazon on the listing are all reasons to ask for a higher ROI.
- How much profit per unit? A high ROI on a very cheap product may only earn a few cents. Set a minimum profit per unit as well.
Write your minimums down and apply them to every line when you analyze a wholesale price list.

Frequently Asked Questions
Why is wholesale ROI lower than arbitrage?
Wholesale products are bought at negotiated prices in bulk, and the same products are reordered. You trade a lower ROI per order for steadier, repeatable sales.
Should I include storage fees in ROI?
Yes, if you expect stock to sit in Amazon’s warehouses for more than a short time, especially in October to December when storage costs more.
Is a higher ROI always better?
Not always. A product with a high ROI that sells once a month can earn less over a year than a fast seller with a lower ROI.
