Our Valuation Methodology

1. Data Sources and Engine

The SmartphoneWorth valuation engine utilizes a proprietary Machine Learning (ML) model trained on millions of historical and real-time data points, including:

• Historical Transaction Data: Past sales prices from major resellers and trade-in platforms.
• Current Market Listings: Real-time scraped data from high-volume marketplaces (e.g., eBay, Swappa) and retailers.
• Manufacturer and Carrier Programs: Published trade-in guidelines and device retention offers.
• Economic and Tech Trends: Inflation data, new device announcement dates, and supply chain reports.

2. Key Factors Affecting the Price

Our algorithm dynamically weights the following variables to calculate the final worth range:

3. Interpreting the Valuation Range

• The High End (Maximum Value)

  This represents the potential price when selling a device in pristine, 'like new' condition via a private marketplace (like eBay or Facebook Marketplace). This route maximizes profit but requires more effort (listing, shipping, dealing with buyers).

• The Low End (Minimum Value)

  This typically reflects the guaranteed price from an instant buyback company or a carrier trade-in program for a device in good-to-fair condition. This method offers speed and convenience but generally lower cash value.
