How This Works

Gross Margin = (Revenue - COGS) / Revenue x 100

Net Margin = (Revenue - COGS - Additional Costs) / Revenue x 100

COGS (Cost of Goods Sold) is your direct product cost including manufacturing and sourcing. Additional costs include Amazon referral fees, FBA fees, shipping, PPC advertising costs, and any other per-unit expenses.

The margin comparison table shows how small price adjustments of +/- $2 and $4 impact your margins and monthly profit, helping you find the sweet spot between competitive pricing and profitability.

Monthly profit = Profit per unit x Units sold per month. Annual projection = Monthly profit x 12 (assumes consistent sales volume).

Frequently Asked Questions

Most successful Amazon sellers target a net profit margin of 15-30%. A margin above 25% is considered strong, 15-25% is healthy, and below 15% is risky because it leaves little room for unexpected costs like returns, PPC spend increases, or fee changes. Top-performing private label sellers often achieve 30-40% margins.
Gross margin only subtracts the direct cost of goods (COGS) from revenue, showing how much you earn before other expenses. Net margin subtracts ALL costs including Amazon fees, shipping, PPC advertising, and overhead. Net margin is the true measure of profitability. For example, a product with 70% gross margin might only have 20% net margin after Amazon's fees and advertising costs.
Amazon fees typically consume 30-40% of your selling price. This includes the referral fee (usually 15%), FBA fees ($3-8+ depending on size and weight), and storage fees. These fees are why a product that costs $5 to make and sells for $25 doesn't yield $20 in profit. Always calculate net margin after all Amazon fees to understand your true profitability.
It depends on your margin elasticity. Use the comparison table to see how price changes affect your monthly profit. Sometimes a $2 price reduction can significantly boost unit sales and total profit even with a lower per-unit margin. However, if your net margin is already below 15%, further price reductions may make the product unprofitable. Test price changes carefully and monitor total profit, not just per-unit margin.
Focus on five key areas: (1) Negotiate better supplier pricing or find alternative manufacturers, (2) Optimize your PPC campaigns to lower advertising cost per sale, (3) Reduce returns by improving product quality and listing accuracy, (4) Consider size and packaging optimization to lower FBA fees, (5) Test gradual price increases of $0.50-$1.00 to find the optimal price point where total profit is maximized.
