About Bikash Roy

Bikash Roy is the founder of Free Live Calculators and an online research specialist with a deep focus on building accurate, accessible digital tools. His work centers on transforming complex formulas and official standards into tools that anyone can use — from a student to a professional.

Expertise & Background

Bikash Roy brings expertise in:

• Online research methodology — cross-referencing official standards (WHO, NIH, government data) to verify every calculator on this site
• Health & wellness tools — BMI, calorie, fitness, and clinical calculators built against WHO and medical standards
• Financial calculators — mortgage, loan, and investment tools verified against standard financial formulas
• Web accessibility — WCAG AA compliance, keyboard navigation, inclusive design
• SEO content strategy — building content clusters that rank and serve real user needs
• Client-side web development — all calculators run in-browser, no data sent to any server

Why Free Live Calculators?

Bikash Roy launched Free Live Calculators after repeatedly encountering calculator sites that were inaccurate, inaccessible, cluttered with ads, or missing the educational context users need to actually understand their results.

The goal: build every calculator the right way — verified formula, official reference data, plain-English explanation, accessibility features, and full supporting documentation. Every time.

Verification Commitment

Every calculator on this site is personally reviewed by Bikash Roy before publication. Reference data tables are verified against primary sources. Worked examples are manually calculated and confirmed. When standards change (e.g., updated WHO guidelines), calculators are updated accordingly.
