About the project

Meet All Tool Central—ATC.

All Tool Central, shortened to ATC or ATC Calculators, is an independent library of free financial calculators built to make everyday money questions easier to explore. The tools use Indian currency, familiar lakh and crore formatting, and explicit assumptions.

01

Why the site exists

Financial decisions often begin with a simple question: what will this loan cost, how much could regular investing build, or how far will inflation move a future goal? A useful calculator should answer the numerical part without hiding the method.

The site is designed for people who want a quick estimate and also want to understand what produced it. No account is required, and the values entered into calculators are processed in the browser rather than submitted as an application for a financial product.

02

What All Tool Central is—and is not

The calculators are educational planning tools. They do not recommend securities, lenders, savings products or tax positions, and they do not replace advice tailored to an individual’s finances.

All Tool Central is not a bank, broker, mutual fund distributor, investment adviser or government website. Rates, regulations, fees and product rules can change, so important decisions should be checked against current official information.
