How to use this calculator

Enter selling price, product cost, Amazon fees, and combined ads plus shipping cost. The calculator estimates profit per unit and net margin.

What the result means

Net margin shows whether the product can survive fee increases, PPC volatility, discounts, and returns. Very low margins are risky even when sales volume looks strong.

Net margin = (Selling price − Product cost − Amazon fees − Ads and shipping) ÷ Selling price × 100.

Use exact SKU-level cost data when available. Account-level averages can hide weak-margin products.

Example calculation

A $65 product with $24 cost, $12 Amazon fees, and $8 ads plus shipping has $21 profit and 32.3% net margin.

Tips for better results

  • Break down margin by SKU, not only account total.
  • Reduce PPC waste before cutting price.
  • Negotiate product cost or MOQ terms.
  • Avoid coupons that erase contribution margin.
  • Compare gross margin and net margin separately.

FAQ

What is a good Amazon profit margin?

A strong Amazon net margin is often 20% to 30% or higher after fees, fulfillment, advertising, shipping, and expected returns.

How do I calculate Amazon net margin?

Subtract product cost, Amazon fees, ads, shipping, storage, and return costs from selling price, then divide profit by selling price.

How can I improve Amazon product margins?

Improve sourcing, raise perceived value, reduce PPC waste, optimize packaging, lower returns, and avoid excessive discounts.

What costs reduce Amazon margins the most?

Common margin reducers include referral fees, FBA fulfillment fees, PPC spend, shipping, storage, returns, and coupon discounts.

Is a 30% Amazon margin realistic?

A 30% net margin is realistic for differentiated products with controlled ad costs and strong sourcing, but difficult in highly competitive commodity categories.
