About Calculator Hub
Calculator Hub is built and maintained by Abishek, an independent developer in India. The goal is simple: accurate, fast, genuinely free financial tools with no signup walls and no lead harvesting.
Methodology
Every calculator shows its exact formula and a worked example on the page. Tax calculators are verified against the Income Tax Department (incometax.gov.in) and updated after every Union Budget — currently verified for FY 2026-27. Deposit and loan mathematics follow standard banking conventions (quarterly compounding for FDs, reducing-balance EMIs).
Privacy
All calculations run in your browser. Your inputs are never sent to a server, stored, or shared. There are no accounts.
Corrections
Found an error? It will be fixed fast — every page links its sources so you can check the maths yourself.
