Free calculators, built for India

Three decisions that cost Indian professionals real money, worked out properly — with every line of the arithmetic shown, so you can check it rather than trust it.

  • Marginal relief just above ₹12 lakh
  • Senior and super-senior slabs
  • Full line-by-line working

Freelance Rate Calculator

  • Accounts for unpaid hours and leave
  • Compares you to real 2026 Indian rate bands

Buy a Flat, or Rent and Invest?

The comparison done honestly: stamp duty, maintenance, rising rent, the EMI split between interest and principal, and the year at which buying finally overtakes investing.

  • Month-by-month loan amortisation
  • Rent inflation and SIP compounding
  • Tells you the crossover year
  • Names what the model does not price

Why these are free, and what the catch is

There isn't one. There is no sign-up wall, no "enter your email to see the result", and nothing you type is sent anywhere — the arithmetic runs inside your own browser, which you can verify by switching off your internet and watching the numbers still work.

What we ask instead: if a calculator saves you money, read the article behind it. Each one is built on a long-form guide that explains where the numbers come from and where they break down. That is the whole business model — useful things, honestly made, and some of you will eventually want writing or spreadsheet work done.

What these are not. They are decision aids, not filings, forecasts or advice. Tax figures should be confirmed on the Income Tax Department portal and with a chartered accountant. Investment assumptions are assumptions — Indian equity returns are volatile and past performance predicts nothing. Every calculator states its own limits at the bottom, in plain language, including the things it deliberately does not price.

Need a calculator like these for your own business?

I build financial and reporting models in Excel — amortisation schedules, pricing models, scenario tables and dashboards — formula-driven and documented, so you can change an assumption without breaking the sheet. Also SEO articles, technical explainers and business reports.
