How Product Feasibility Is Calculated

The feasibility score combines profitability and competition metrics to help you quickly assess if a product is worth pursuing on eBay.

Feasibility Score = (Profitability Score × 0.6) + (Competition Score × 0.4)

  • Profitability Score: Based on net profit margin (10% margin = 100 points)
  • Competition Score: Sales density = monthly sales / competing listings (higher = better)
  • Weighting: Profitability is weighted 60%, competition 40%

Real Example: Analyzing a $45 Product

Let's evaluate a typical eBay product to see how the research tool works:

  • Average Selling Price: $45.00, Product Cost: $15.00
  • Monthly Sales: 120 units, Competing Listings: 85
  • Final Value Fee: 13.25%, Shipping Cost: $6.00

Step 1: Gross Margin = ($45 - $15) / $45 × 100% = 66.7%
Step 2: eBay Fees = $45 × 13.25% + $0.30 = $6.26
Step 3: Net Profit = $45 - $15 - $6.26 - $6 = $17.74
Step 4: Sales Density = 120 / 85 = 1.41
Step 5: Feasibility Score = (77 × 0.6) + (70 × 0.4) = 74.2

Key Factors That Impact Your Research

Several variables determine whether a product will be profitable on eBay:

  • Selling Price (High): Higher prices typically mean higher per-unit profits, but may reduce sales volume
  • Sales Density (High): More sales relative to competitors indicates strong demand with manageable competition
  • Product Cost (High): Lower costs directly improve margins, but quality and sourcing reliability matter
  • Category Fees (Medium): Different eBay categories have different final value fee rates

What This Tool Doesn't Include

This tool provides a starting point for your research. You should also consider:

  • Listing Quality: Well-optimized listings with good photos convert better
  • Seller Reputation: Established sellers with high feedback scores get better placement
  • Seasonality: Many products have peak demand periods
  • Promoted Listings: Ad spend can boost sales but reduces net profit

FAQ About eBay Product Research

What is a good feasibility score on eBay?
A score above 70 indicates a strong opportunity. Scores between 50-70 are worth investigating further, while scores below 50 suggest high competition or low margins. Always verify with actual eBay sales data.
How do I find monthly sales data for eBay products?
Use eBay's "Sold Items" filter to see recent completed listings. Multiply the average daily sales by 30 to estimate monthly volume. Some third-party tools like Terapeak or Algopix provide this data directly.
Should I avoid highly competitive categories on eBay?
Not necessarily. High competition often means high demand. Focus on products where you can differentiate—better quality, faster shipping, or better customer service. Look for "niches within niches" that larger sellers overlook.
How important is sales density in product selection?
Sales density is critical—it tells you how many sales each listing gets on average. A density of 1.0 means each listing sells once per month. Aim for density above 1.5 for products with strong demand relative to supply.
What price range works best for eBay beginners?
Beginner sellers often find success with products in the $25-$75 range. This price point balances profit margins with reasonable competition. Avoid ultra-low priced items (under $10) unless you have very low sourcing costs.
