Meet Our Founders
Two passionate developers from Croatia dedicated to improving access to high-quality financial tools.
Jurica is a Croatian entrepreneur who became the youngest registered company director in Croatia at 18. He decides which calculators we build and what each one has to answer before it ships.
His method is simple: find the question people are actually typing into a search box, then build the smallest tool that answers it properly. He runs the same playbook across our other sites, including egamer.hr and MyCarCalc.
Product Direction
Decides which calculators get built and what question each one must answer.
Source Research
Tracks IRS limits, contribution caps and rate data so the numbers stay current.
Marko holds a B.Sc. in Computer Science from FOI, University of Zagreb. He writes the code, implements the formulas, and is responsible for the platform staying fast and correct.
Every calculator here is hand-built rather than generated from a template — amortization schedules, progressive tax brackets and compounding are each implemented and checked against published sources before the page goes live.
Calculator Engineering
Implements the math — amortization, tax brackets, compounding — and the tests behind it.
Privacy & Performance
Keeps every calculation in your browser — no inputs are sent to a server.
Our Impact
Building the most comprehensive collection of free finance calculators online
