About

Free calculators, no sign-up, no catch

Paisarithm exists to answer one question quickly: "what does this actually mean for my money?" Every calculator on this site runs entirely in your browser — your numbers are never sent anywhere or stored.

Why we built this

Most financial calculators online are buried inside banks, brokerages, or apps that want your phone number before showing you a number. We wanted a place where you could check an EMI, a SIP projection, or a tax comparison in a few seconds, with the working shown clearly enough that you could redo it on paper if you wanted to.

How we stay free

This site is supported by advertising and, where relevant, by links to financial products that may pay us a referral fee if you choose to sign up through them. This never affects which result a calculator shows you — the maths is the maths, regardless of how the site is funded.

What this isn't

Paisarithm is an educational tool, not a financial advisor, chartered accountant, or registered investment adviser. Every result is an estimate based on the numbers you enter and standard public formulas. For decisions that matter — a home loan, a tax filing, a big investment — please confirm the numbers with a qualified professional. See our full disclaimer.
