What is Amazon Wholesale?

Amazon wholesale is a business model where sellers purchase brand-name products directly from manufacturers or authorized distributors at wholesale prices and resell them on Amazon. Unlike retail arbitrage, wholesale allows you to sell under the brand name with full listing privileges, access to Amazon's Brand Registry benefits, and typically more stable sourcing relationships. Margins are typically 20-35% with lower risk than private label due to established product demand.

How to Calculate Wholesale Profit

Follow these steps to calculate your wholesale profit accurately:

  1. Enter your Amazon Sale Price ($) - current or target selling price on Amazon
  2. Enter your Wholesale Cost ($) - what you pay per unit from your supplier
  3. Enter your Shipping to Amazon ($) - cost per unit to ship to FBA warehouse
  4. Enter your FBA Fulfillment Fee ($) - Amazon's picking, packing, and shipping fee
  5. Enter your Referral Fee (%) - Amazon's category-based referral percentage
  6. Enter your Prep Cost / Unit ($) - cost for inspection, labeling, poly bagging
  7. Enter your Units Purchasing - number of units in this purchase order

Wholesale Profit Formulas

Referral Fee = Sale Price × (Referral Fee% ÷ 100)

Total Cost / Unit = Wholesale Cost + Shipping + FBA Fee + Referral Fee + Prep Cost

Net Profit / Unit = Sale Price - Total Cost / Unit

Profit Margin = (Net Profit ÷ Sale Price) × 100%

ROI = (Net Profit ÷ Wholesale Cost) × 100%

Total Investment = Wholesale Cost × Units

Real-World Example

Example: You purchase a brand-name product at $25 wholesale, selling for $49.99 on Amazon, with $2 shipping, $5.50 FBA fee, 15% referral fee, $0.75 prep cost, buying 50 units:

Referral Fee: $49.99 × 15% = $7.50

Total Cost / Unit: $25 + $2 + $5.50 + $7.50 + $0.75 = $40.75

Net Profit / Unit: $49.99 - $40.75 = $9.24

Profit Margin: 18.5%

ROI: 37.0%

Total Investment: $25 × 50 = $1,250

Total Profit: $9.24 × 50 = $462

Understanding your wholesale profit helps you:

  • Negotiate better prices - Know your margin requirements before buying

Frequently Asked Questions

Is Amazon wholesale profitable in 2026?

Yes, wholesale remains profitable with 20-35% margins. Success requires: finding unique product opportunities before saturation, building relationships with reliable distributors, optimizing logistics to reduce shipping costs, and maintaining competitive pricing while protecting margins.

How much capital do I need for wholesale?

Starting capital varies: $2,000-5,000 for initial testing with 3-5 products, $10,000-25,000 for meaningful inventory to generate $1,000-3,000/month profit. Many sellers start small to test products before scaling orders. Some distributors offer NET-30 terms for established sellers.

What's the difference between wholesale and distributor pricing?

Wholesale pricing is typically 40-60% of MSRP from distributors. Some brands offer MAP (Minimum Advertised Price) policies that affect your pricing flexibility. Direct manufacturer sourcing offers best margins but requires larger orders and more negotiation.

How do I avoid counterfeit or authentic products in wholesale?

Verify authenticity by: requesting distributor licenses and authorization letters, checking FDA/regulatory compliance for relevant products, inspecting packaging for authentic branding, and building relationships with established distributors rather than unknown sellers.

Can I sell wholesale products in FBA and merchant fulfilled?

Yes, both options work. FBA offers Prime eligibility and hands-off fulfillment but has higher per-unit costs. Merchant Fulfilled (MFN) offers lower fees but requires your own logistics. Many wholesale sellers use both: FBA for high-velocity items, MFN for oversized or slower-moving inventory.
