About

Who built this

My name is Gianni V.S., a developer based in Belgium with a strong interest in self-directed investing. I built Investment Calculator because I couldn't find a free, reliable calculator that combined accurate financial math with clear educational content. The site launched in 2025 and now offers more than 20 free calculators and guides.

Editorial approach

• All calculator formulas are based on standard financial mathematics, using the same methods as textbooks and professional tools.
• External data (inflation rates, index returns, metal prices, crypto prices) is sourced from public datasets and refreshed regularly.
• Content is written to be factual and educational. It does not constitute financial advice.
• Pages are reviewed and updated whenever underlying data or methodology changes.
