Meet Our Founders

Two Croatian developers who got tired of scattered, ad-heavy calculator sites. So we built a clean, free set of tools for everyday car buyers and owners.

Entrepreneurial Vision

Jurica is a Croatian entrepreneur who became the youngest registered company director in Croatia at just 18 years old. He has a knack for spotting what people actually need online and building simple tools to help them out.

Building User-Centric Platforms

While still a high school student at Varaždin's Electromechanical School, Jurica identified market gaps and founded Kupi Key d.o.o. in March 2012. By 2014, the company had cleared over HRK 1 million in net profit, serving over 300,000 customers worldwide.

"We wanted to build the kind of calculator site we'd actually want to use ourselves — no clutter, no sign-ups, just quick answers."

Technical Excellence

Marko is a Croatian developer who enjoys building useful web tools. He handles the code, the formulas, and the overall platform — making sure every calculator works the way you'd expect it to.

Academic Foundation

B.Sc. Computer Science from Faculty of Organization & Informatics (FOI), University of Zagreb. He's been building web projects since university and brings that experience to making MyCarCalc reliable and easy to use.

"I double-check the math behind every calculator we ship. These are estimation tools — not professional advice — but we make sure the estimates are solid."

Why We Built This

We wanted a single place where you can quickly estimate car-related costs without wading through sign-up forms or paywalls. That's it — simple tools, free to use, no strings attached.

Free & Simple

No accounts, no paywalls. Just open a calculator and go.

Honest Estimates

We use standard formulas and tell you what goes into each calculation.

Not Professional Advice

Our tools give estimates to help you plan. For big decisions, talk to a professional.
