About FinTools
FinTools was born from the combination of two passions: programming and personal finance. Created by a developer with a postgraduate degree in Computer Science and a genuine interest in investments and financial planning, the project aims to simplify calculations that often seem too complex.
Our Story
It all started when, while researching investments, I noticed that many online calculators were confusing, full of intrusive ads, or simply didn't explain what they were calculating. As a developer, I thought: I can do something better.
The first tool was a simple compound interest calculator. But what set it apart was the educational explanation alongside the results, clear charts, and the absence of distractions. The positive feedback motivated me to expand the project.
Today, FinTools offers over 20 financial calculators, from investment simulators to Brazilian tax calculators. Each tool is developed with the same care: precision in calculations, clean interface, and educational content.
