Amazon Wholesale & Retail Arbitrage Profit Calculator

Amazon Wholesale and Retail Arbitrage sellers rely heavily on exact margin and return-on-investment (ROI) figures before sourcing products in bulk. Buying inventory without accurately factoring in FBA fees, prep costs, referral fees, and inbound shipping can easily turn a seemingly profitable product into a loss.

Key Metrics Evaluated by Wholesale Sellers

To determine if a brand or distributor item is worth sourcing, successful sellers assess four fundamental metrics:

• Profit Margin: The percentage of net revenue remaining after subtracting all procurement and Amazon selling expenses.
• Return on Investment (ROI): The profitability percentage measured against your total capital outlay (Buy Cost + Prep/Inbound Shipping).
• Total Batch Net Profit: The aggregate net return expected across your total ordered units.
• Break-Even Sourcing Price: The minimum resale price needed to avoid capital loss.

Frequently Asked Questions (FAQs)

What is a good target ROI for Amazon Wholesale sellers?

Most wholesale sellers aim for a minimum of 25% to 30% ROI and a 15% net profit margin to account for price fluctuations, buy box competition, and potential customer return costs.

What is the difference between ROI and Profit Margin?

ROI measures how hard your money is working based on what you spent to acquire the inventory. Profit Margin measures how much profit you retain from every dollar generated in sales revenue.
