Bank-standard EMI, FD and RD maths and the latest tax slabs.
A clean experience on phone, tablet and desktop, with dark mode.
QuickKit brings the everyday tools you search for into one fast, clean website. Plan a home or car loan with the EMI calculator, compare tax regimes with the income tax calculator, project your investments with the SIP and FD calculators, check a bill with the GST calculator, or debug code with the JSON formatter and JavaScript validator.
Every tool works on desktop and mobile, supports dark mode, and processes your data locally — nothing you type is sent to a server.
