Why it exists

While filing his own income tax return, Ankit wanted a simple income tax calculator and a FIRE calculator that showed the working instead of just a final number. He could not find one he trusted, so he built it. The site grew from there, one calculator at a time.

Who builds it

Ankit Bansal is a software engineer who has been building backend and fintech systems since 2015.

• Product Engineer at Peerlist (since June 2023), where he built the Autosend email delivery platform from the ground up.
• Senior Software Engineer at GoJek (2021–2023), where he built merchant-lending integrations, KYC verification flows and real-time credit-eligibility checks for more than a million active users.
• Earlier roles at Antbrains, Clairvoyant India and Persistent Systems (for Cisco), building enterprise APIs and data-processing systems.

Bachelor of Engineering in Computer Science, University of Pune (2015).

How the numbers are checked

• Tax slabs, rebates, surcharge and cess come from one shared tax engine that follows the Finance Act for the year shown. No calculator keeps its own copy of the slabs.
• Automated tests run the formulas on every build, including independent cross-checks and identities such as total paid minus total interest equalling the loan amount, to the rupee.
• Every calculator lists its primary sources — the Income Tax Department, RBI, SEBI, AMFI and the official scheme notifications.
• Pages are re-checked when the numbers change: the Union Budget, the quarterly small-savings rate notifications and the EPFO interest rate.
