About Kulkalotar

Kulkalotar is a free calculator hub built to answer the questions people actually ask every day — from mortgage payments and BMI to GPA and square footage. Every calculator on this site is hand-written, runs entirely in your browser, and shows you the formula and a worked example so you understand the result, not just the number.

Who builds this

Kulkalotar is a small independent project. We do not sell user data and we do not run ads above the calculator itself — ads only appear below the tool so they never get in your way. The site is open about its sources: every calculator that touches money, health, or other consequential decisions links to the authoritative source (IRS, WHO, ECB, NASA, etc.) used for its formulas.

What we don't do

We do not give personalized financial, medical, or legal advice. The site is informational. If you're making a real decision involving money or health, please talk to a qualified professional.
