How to check an item's resale value before you buy it

1. Pin down the exact model

Price differences between variants are often bigger than between conditions. Read the model number on the label, the box or the settings screen. Check storage size, model generation, colour where it matters, and for lenses the mount. "Sony headphones" is not a price; "Sony WH-1000XM4" is.

2. Look at comparable listings, not the first result

Search the exact model on eBay and filter out what does not compare: other generations, accessories sold alone, bundles with games or extra lenses, "for parts" items and listings from far away with expensive shipping. Look at several countries: the same item can sell for noticeably different prices in Germany, France or Italy.

3. Correct for asking price and condition

Most listings show asking prices, and items usually sell for less. Take the middle of the realistic range, not the highest listing, and adjust for condition: a "good" item does not fetch a "like new" price. If only a handful of comparable listings exist, treat any estimate with caution.

4. Subtract fees and shipping

What you keep is the sale price minus marketplace fees and the shipping you pay. On eBay.de private sellers pay no selling fees within Germany, business sellers do; on Vinted the buyer pays the fees. See eBay.de fees for private and business sellers and where to sell used electronics in Europe.

5. Work out your maximum price

Decide the return you want, then divide what you keep by 1 plus that return. Example: a Nintendo Switch OLED expected to sell for €176, no selling fee, €6 shipping, so you keep €170. For a 40% return the most you should pay is €170 ÷ 1.4 = €121. Anything below is a buy; above it, negotiate or walk away.
