Who maintains this site

A founder-led calculator platform focused on clarity.

The site started with percentage calculators and now includes finance, fitness, math, and everyday tools. The goal is simple: give people a fast place to check a number without hiding the formula behind clutter.

Krishnansh Tiwari founded the website to make common calculations transparent, privacy-first, and easy to verify. He independently maintains the calculator library, educational content, formula explanations, and trust pages.

Why this website exists

People need quick calculations for shopping, school, finance, health planning, construction, and everyday decisions. This site brings those tools into one privacy-first place with clear explanations and responsible disclaimers.

What users get

  • Percentage tools for school, shopping, tips, taxes, and comparisons.
  • Finance calculators for loans, mortgages, interest, taxes, salary, and investments.
  • Health and fitness calculators for BMI, calories, BMR, body fat, pace, and pregnancy estimates.
  • Everyday calculators for dates, times, grades, GPA, subnetting, passwords, and conversions.

Commitment to accuracy

Calculator formulas are kept separate from presentation updates. When a calculator gives an estimate, the page describes the inputs and assumptions so the result can be used as a planning aid rather than mistaken for an official quote.
