How to use this calculator

Enter the item selling price, sourcing cost, total eBay/payment fees, and shipping plus advertising cost. The result shows net profit, margin, cost pressure, and a health score for the listing.

What the result means

A higher margin means the listing can absorb fee changes, returns, discounts, and promoted listing costs. A low margin means small cost increases can turn the item unprofitable.

Net Profit = Selling Price - Product Cost - Fees - Shipping and Ads. Net Margin = Net Profit / Selling Price × 100.

Benchmark guide: 30%+ is strong, 15% to 30% is workable, and below 15% needs cost or price action.

Example calculation

If a product sells for $60 with $25 cost, $8 fees, and $10 shipping plus ads, net profit is $17 and net margin is 28.3%.

Tips for better results

  • Raise price before increasing ad spend.
  • Reduce packaging and fulfillment cost first.
  • Avoid discounts when margin is already below 15%.

FAQ

How much profit margin should I make on eBay items?

Many eBay sellers target at least 20% to 30% net margin after fees, shipping, ads, and packaging. Lower margins can work only with high volume and low return risk.

How do I calculate eBay profit after final value fees?

Subtract product cost, eBay fees, payment fees, shipping, packaging, and advertising from the selling price, then divide net profit by selling price for margin.

Is a 15 percent margin good for eBay reselling?

A 15% net margin is usually average. It may be acceptable for fast-moving inventory, but it leaves limited room for returns, fee changes, or promoted listings.

How much should I mark up products for eBay?

Your markup should cover product cost, fees, shipping, ads, returns, and target profit. The correct markup depends on category, demand, and fulfillment cost.

Why is my eBay profit lower than expected?

Common causes include underestimated shipping, promoted listing fees, payment fees, packaging costs, returns, and pricing too close to cost.
