About Calculator Universe

Calculator Universe is a free suite of India-specific calculators by SmartAI Labs. Everything runs on your device — no account, and the numbers you enter are never uploaded.

Calculator Universe is published by SmartAI Labs as a free educational suite. The interactive calculators load in the application panel; the copy on this page explains how we expect the tools to be used.

What Calculator Universe is

Calculator Universe is a free suite of India-specific calculators published by SmartAI Labs. It is the product people open when they have a salary slip, a loan offer or a SIP folio and need the arithmetic before they call a bank or a CA. The lab that publishes it is described at smartailabs.in/about; a longer formula guide lives at smartailabs.in/calculator-universe.

Finance Studio covers SIP and lumpsum investing, XIRR, reducing-balance EMIs and prepayment, new-versus-old income tax, HRA, GST, capital gains after the July 2024 changes, PPF, EPF, Sukanya Samriddhi, NPS, SCSS and brokerage as Indian contract notes itemise it. Health, maths, developer and date tools sit beside that. Astrology pages are cultural / educational, not advice.

How a calculation runs

You pick a tool, type inputs, and the formula encoded for that screen runs in the browser (or on the Android app). There is no account. Favourites and theme stay in local storage on your device. Closing the tab or clearing site data removes them. We cannot read that storage remotely.

Advertising pays for the free web app. The numbers you type are not sent to us and are not the product we sell. See the Privacy Policy for cookies and AdSense / AdMob.
