CarTax.gr revenue: €415 in 13 days from a car-import cost calculator

CarTax.gr estimates the cost of importing a used car into Greece from a marketplace listing. Its solo founder reported €415 in revenue and 60 paying users in the first 13 days.

A narrow tool for an expensive purchase

CarTax.gr lets a buyer paste a German used-car listing and receive a report estimating Greek registration tax and the landed cost. The public website shows example reports, the calculation method, and paid report packages.

The product focuses on a specific decision: whether a particular imported vehicle still looks attractive after extra costs. Its website identifies the output as an informational estimate, with the final assessment left to customs.

CarTax.gr revenue: €415 in its first 13 days

In an October 13, 2026 Reddit update, the founder reported about €415 total revenue from 60 paying users and 86 transactions. Launch traffic included roughly 11,700 sessions and 1,200 signups. This is cumulative launch revenue rather than MRR.

Organic TikTok and branded Google searches contributed traffic. A paid TikTok test brought visits but no sales. Revenue slowed in the second week, while repeat report purchases suggested that dealers or importers might be a useful audience to investigate.

Why the repeat buyers matter

The interesting business question is how often the same customer needs the report. An individual checking one prospective purchase and a dealer comparing inventory have different needs. The founder’s early data offers a concrete reason to explore both audiences before deciding how to package the product.
