Calxo is built and written by me, Vignesh Sampath Kumar. I’m an SEO Lead at PipeRocket Digital in Chennai. Before Calxo I built EVBlogs.in, an electric vehicle news and review site for Indian buyers.

I started Calxo because most Indian calculator sites are either generic global tools that use dollars and US tax rules, or they’re built by a lender or AMC whose only goal is capturing your phone number. Neither is useful when you just want to run a quick EMI check or figure out whether the old or new tax regime saves you money this year.

Every calculator on Calxo is built from the actual statute: RBI Master Directions, the Income Tax Act, EPFO circulars, GST Council notifications. The math is cross-checked against CBDT, EPFO, and published bank rate cards before going live. The methodology page has the full process.

I am not a Chartered Accountant or a SEBI-registered advisor. What I am is someone who has spent too many hours arguing with EMI quotes, tax projections, and “is this a good investment” questions from family. Calxo is the calculator I wished existed when I was figuring this out myself.

If a formula looks wrong, or a rate is out of date, email me directly at avmedianews321@gmail.com. Corrections are usually live within 48 hours.
