SellerSwarm - AI-powered Amazon Seller Tools

60% of new sellers fail because they didn't calculate their margins correctly. Margin shows you the financial truth of any product before you invest a cent.

The Truth Nobody Tells You

You found a product that 'seems profitable'. The supplier gives you a good price, you see the selling price on Amazon, and you think 'this works'. But when you add FBA fees, shipping costs, PPC, returns, and all the hidden costs nobody mentions... you discover your real margin is 8% instead of the 40% you calculated. You already invested $5,000 in inventory. Too late.

Margin: The Real Numbers

Margin doesn't let you guess. Enter your product cost, target selling price, and Margin calculates ALL costs: FBA fees, Amazon commissions, shipping costs, estimated PPC, returns, and even long-term storage costs. It shows your real margin, exact break-even point, and how many units you need to sell to be profitable.

Decide with Data, Not Hope

Ask Margin: 'What's my real margin if I buy this product at $12, sell it at $35, and spend 15% on PPC?' Margin gives you a complete breakdown: Amazon fees ($5.25), FBA ($4.80), PPC ($5.25), estimated returns ($1.05). Net margin: $6.65 (19%). Now you can decide if that 19% justifies the risk, or if you need to negotiate a better price with your supplier.

Avoided a $15,000 Mistake

Andrea was about to order her first inventory: 500 units for $6,000. Her 'quick calculation' showed 35% margin. Before confirming the order, she asked Margin. Margin showed her that with all real costs, her margin was 12%. Worse yet, she'd need to sell 320 units just to recover her initial investment. Andrea negotiated a better price with her supplier, reduced her first order to 200 units, and launched with 28% margins. Margin saved her from a mistake that would have killed her business before it started.

Numbers Don't Lie

You can ignore the numbers, but the numbers won't ignore you. Margin gives you the financial truth of your business, no filters, no unjustified optimism. Knowing your real numbers is the difference between building a sustainable business and burning money hoping things 'work out'. Do you know your real numbers?
