You came from one of our calculator sites

We built the calculator you came from.
What can we build for you?

Pénzkalkulátor (Hungary) and Geldrechner (Austria) are ours: salary, tax, loan and inflation calculators built on the 2026 rules and official statistics. We wrote the data collectors and the sites themselves, and we keep them running. We build websites, online stores, business software and SaaS products the same way — for companies, in English or German.

What we build

Pick what you need

Every project is custom code — no templates, no licence fees. The prices below are starting points; the itemised quote comes by email after we talk.

Custom calculator, data page

Quoted per project

What you see on the calculator sites, built for your own website: a gross-to-net calculator for an accountancy, a loan calculator for a broker, a cost calculator for an estate agent. The price depends on how many calculators and data sources we build in.
