About Gainly

Gainly makes free calculators for the money decisions people in India face every year: how much to invest, which loan to take, which tax regime to pick and what a deposit will pay.

How we build our calculators

• Every calculator follows the method banks, India Post and the Income Tax Department use, and shows the formula with a worked example.
• Rates and rules (tax slabs, PPF and small savings rates, GST slabs) are checked against official notifications and updated when they change.
• Calculations run on our server and in our apps the same way, so you get the same answer everywhere.

What our numbers are not

Results are estimates for planning. They are not an offer from any bank, and not financial, tax or investment advice. For decisions with large amounts or complex tax situations, speak to a qualified adviser. See our disclaimer.

How the site is funded

Gainly is free to use and is supported by advertising. Ads are served by Google and are clearly marked. Advertisers have no say in our calculations or content.
