About BASERASTECH India Tools
BASERASTECH India Tools is a free collection of calculators, converters and everyday tools for people in India, published by BASERASTECH (www.baserastech.com). It covers loans and EMIs, savings and investments, income tax and GST, salary and payroll, health, education, dates, unit conversions, text and developer utilities.
We built it because most Indian finance calculators online either hide the method behind a sign-up form or apply rules from another country. Every tool here gives an instant answer and shows how that answer was reached: the formula, a worked example and the assumptions behind it.
What makes these tools different
Indian conventions come first. Amounts are shown in rupees with lakh and crore grouping, EMIs use the reducing-balance method that Indian banks use, fixed deposits compound quarterly the way bank FDs do, and salary tools follow the EPF, gratuity and professional-tax rules that appear on Indian payslips.
Tax rules are kept per financial year. Slabs, rebates, the standard deduction, surcharge, cess and capital-gains rates for each year live in their own rule file, so a calculator never mixes rules from different years and a new Budget can be applied in one place.
Your data stays with you. Every calculation runs inside your browser. What you type is not sent to us, there are no accounts, and nothing asks for your name, phone number or PAN.
How calculations are checked
Each calculator has a separate calculation engine with automated tests that check its results against hand-worked reference cases: for example, that a standard home loan gives the EMI a bank would quote, that a salary of ₹12.75 lakh pays no tax under the new regime, and that HRA exemption is the least of its three limits. More than 600 of these tests run every time the site is rebuilt, so a change that breaks a formula is not published.
Rates and limits come from official sources: the Income Tax Department and CBDT notifications for income tax, CBIC for GST, EPFO for provident fund, and the Ministry of Finance for small-savings rates. Where a figure is announced but not yet final, the tool says so.
In-depth guides on the most used tools, and the articles in the Guides section, show the date they were last reviewed.
Corrections
If you find a result that looks wrong, please tell us through the Contact page with the tool name and the inputs you used. Confirmed errors are fixed and the corrected version is published as soon as it passes the tests.
How the site is funded
Every tool is free to use, without sign-up or paid plans. The site is supported by advertising from Google AdSense. Ads are kept in their own spaces and never placed inside a calculator or its results, and advertisers have no influence over the content.
