About ThriftRupee
India's friendliest personal finance calculator — built for real people, not spreadsheet experts.
Our mission
Financial decisions — buying a home, planning retirement, choosing between old and new tax regime — are among the most important decisions in a person's life. Yet the tools to understand them are either too complex, too generic, or buried behind login walls.
ThriftRupee exists to change that. We build financial calculators that speak the language of Indian personal finance — ₹30L home loans, 8.5% SBI rates, Section 80C deductions, PMAY subsidy — and make them available to everyone, for free, forever.
What we stand for
India-first
Every default, every preset, every example is calibrated for Indian users. No US-centric assumptions.
Completely free
No premium tier. No account required. No ads. All 137 calculators are free — always have been, always will be.
Instant & private
All calculations happen in your browser. We never see your numbers. No data is ever sent to our servers.
Honest
We show you the full picture — including the interest you'll actually pay, the inflation that will erode your corpus, and the true cost of borrowing.
Important disclaimer
ThriftRupee calculators provide estimates based on mathematical formulas and the inputs you provide. They are for informational and planning purposes only and do not constitute financial, tax, or legal advice.
Always verify results with your bank, financial advisor, or chartered accountant before making significant financial decisions. Interest rates, tax slabs, and scheme rules change — we aim to keep our calculators updated but recommend checking official sources for the latest figures.
