About Calc Labz

Calc Labz is a free, open-access calculator platform built by a small team of engineers and finance professionals in India. We believe everyone deserves access to accurate, trustworthy calculation tools — without paywalls, signups, or data collection.

Our Mission

We started Calc Labz with a simple observation: most online calculators are either buried behind ads and popups, or they give results without showing the methodology. We wanted to build something different — a platform where every calculation is transparent, every formula is documented, and every result can be verified.

Today, Calc Labz offers over 300 calculators spanning finance, health & fitness, mathematics, education, engineering, and everyday decision-making. Each tool is designed to give you clear, actionable results with full transparency into how the numbers are computed.

Who We Are

Calc Labz is maintained by Sagar Sahni and a small editorial team based in India. Our team includes contributors with backgrounds in:

  • Software Engineering — Building reliable, accessible web applications
  • Personal Finance — Understanding Indian tax laws, investment instruments, and banking products
  • Data Analysis — Ensuring our formulas and methodologies are accurate and well-sourced

We are not a financial advisory firm, a medical practice, or a licensed professional services company. We build tools that help you understand numbers — always consult qualified professionals for decisions about your money, health, or legal matters.

How We Ensure Accuracy

Every calculator on Calc Labz follows our editorial policy. In short:

  • Formulas are sourced from established textbooks, government publications, or industry-standard references
  • Financial calculators reference current tax slabs from the Income Tax Department of India, RBI circulars, and SEBI guidelines where applicable
  • Health calculators use clinically validated formulas (e.g., Mifflin-St Jeor for BMR, Devine formula for ideal weight)
  • All calculators include a methodology note explaining the formula used
  • We display "last updated" dates so you know when formulas were last verified

Privacy & Data

Calc Labz does not collect personal data. All calculations happen in your browser — no data is sent to any server. We do not require signups, accounts, or email addresses to use any calculator. Read our full Privacy Policy for details.
