Managing money in India means juggling a particular set of rules: GST on what you sell, TDS on what you earn, 80C deductions to chase before March, and a row of savings schemes (PPF, EPF, NPS, SSY) each with its own rate and lock-in. This page gathers the CrispToolHub tools built specifically for that world, so you can run the numbers yourself instead of guessing or waiting on someone else.

Start with the income tax calculator to compare the new and old regimes for FY 2025-26, then use the HRA exemption calculator and the 80C planners around PPF, EPF and NPS to see which deductions actually cut your bill. If you are saving for a goal, the SIP and investment calculator and the step-up SIP calculator show how regular contributions compound over time.

For business owners and freelancers, the GST calculator, GST late fee calculator and freelance tax calculator cover the day-to-day, while the invoice generator turns out a proper GST invoice as a PDF in seconds. Buying a home? Pair the loan eligibility calculator with the property registration cost and rent vs buy tools to see the full picture before you commit.

Beyond money, students lean on the CGPA calculator and attendance calculator, families use the BMI and pregnancy tools, and there is a lighter side too with the Am I Rich? income-percentile tool. Every one of them is free, works on your phone, and keeps your data on your device. The rates shown are verified against official Indian sources, but they do change, so treat results as estimates and confirm anything important before you act.

FAQ

Frequently asked questions

Are these tools free for people in India?

Yes, every tool is free with no sign-up, no daily limit and no payment. The financial calculators use current Indian rates: PPF at 7.1%, EPF at 8.25%, SSY at 8.2% and GST 2.0 slabs. Everything runs in your browser, so your salary, savings and tax figures never leave your device.

Which tools are most useful at tax time in India?

During filing season the income tax calculator (new vs old regime), the HRA exemption calculator, the capital gains calculator and the 80C planners around PPF, EPF and NPS see the most use. Together they help you estimate your liability, pick the cheaper regime and plan deductions before the year ends.

Do the GST tools follow GST 2.0?

Yes. The GST calculator uses the GST 2.0 slabs (0%, 5%, 18% and 40%) effective from September 2025, and splits tax into CGST plus SGST for intra-state or IGST for inter-state supply. The GST late fee calculator works out the GSTR-3B daily penalty and the cap by turnover.

Can I generate a GST invoice for my business?

Yes. The invoice generator creates a clean GST invoice you can download as a PDF, with your GSTIN, line items, tax split and totals. There are also receipt and quotation generators for the rest of your billing. Nothing is uploaded; the PDF is built in your browser.

Are the financial figures kept up to date?

We verify rates against official sources such as the Income Tax Department, EPFO and India Post, and refresh them when they change. Rates and rules do change, though, so treat the results as planning estimates and confirm anything important with the relevant authority or a qualified adviser.
