1. Understand the 3 Stages of Tech Depreciation

Unlike furniture or classic cars, consumer technology depreciates rapidly. On average, flagship smartphones lose 30% to 40% of their retail value within the first 12 months, and another 15% to 20% in year two. Budget laptops and generic accessories drop even faster.

2. The Decisive Factor: Battery Health

For modern smartphones, tablets, and laptops, battery capacity is the single most scrutinized specification. A phone with 95%+ maximum capacity easily commands a $40 to $70 premium over an identical model sitting at 81% that will soon require battery replacement.

3. Factor in the Original Box and Accessories

Original packaging, genuine charging bricks, and cables reassure cautious buyers that the device was well-cared for and not acquired illicitly. Having the complete original box typically increases sale speed by 50% and adds 5% to 10% to your realized price.

4. Research Completed Sales, Not Asking Prices

A common mistake is searching current classifieds listings to set prices. Many of those listings are overpriced items that have failed to sell. Instead, search completed and sold transactions to discover what real buyers actually paid in the last 14 days.

1. Platform Commissions

Most commercial marketplaces assess a 10% to 15% final value fee on the entire transaction amount, including shipping charges. On a $100 sale, that represents $13 to $15 immediately deducted.

2. Payment Processing Surcharges

Credit card and digital wallet processors levy 2.9% to 3.5% plus a fixed $0.30 to $0.40 transaction fee. On low-ticket items under $15, fixed fees eat a disproportionate share of margin.

3. Boxes, Bubble Wrap, and Labels

Packaging materials are rarely free. Quality corrugated boxes, bubble wrap, packing tape, and thermal shipping labels average $2.50 to $4.50 per shipment. Factor packaging into your item cost before setting list prices.
