Kleinanzeigen profit formula 2026: calculate the deal before buying
Last reviewed: 08/10/2026
Quick answer
Profit = realistic sale proceeds - buy cost - shipping - packaging - promotion - travel - other deal costs.
Kleinanzeigen can appear fee-light, but negotiation, travel and time can turn a strong-looking flip into a weak one.
Use profit and ROI together
The same EUR 20 profit has a very different capital effect on a EUR 20 purchase versus a EUR 200 purchase. At the same time, very high ROI on only EUR 2 absolute profit may not be worth your time.
Practical rule
Set both a minimum profit and minimum margin. If a deal only works under optimistic assumptions, it is not a strong baseline purchase.
