Property maths, made simple and free
PropertyTools India exists because buying, building or selling property in India involves a dozen calculations that nobody explains clearly — and most of the tools that do exist want your email first.
Our mission
To give every Indian property owner, buyer and self-builder free access to accurate, well-explained calculations — without a paywall, a sign-up form, or a wall of advertising between them and the answer.
Property is the largest financial decision most Indian families ever make. The arithmetic behind it should not be a mystery, and it should not cost anything to check.
Our vision
A single, trustworthy place where anyone can work out what a property decision actually costs — in Indian units, with Indian rates, and with the assumptions stated openly on the page.
We would rather be the site people bookmark and come back to than the one that ranks for everything and helps with nothing.
Why we built this
Ask most first-time buyers what stamp duty will cost them and they will not know. Ask a self-builder how many cement bags a slab needs and they will call the contractor and take his word for it. Ask someone selling a flat whether their gain is short-term or long-term and you will usually get a shrug.
None of these are hard calculations. They are just poorly explained, scattered across a dozen sites, buried in PDFs, or locked behind a lead-capture form. We put the seven that matter most in one place, showed the working, and made them free.
Who these tools are for
- First-time home buyers working out what an EMI really costs over twenty years, and what to keep aside for stamp duty and registration.
- Self-builders budgeting a house before appointing a contractor, and cross-checking material quantities against a quotation.
- Land owners and farmers translating between bigha, marla, kanal, cent, gaj and the hectares written in the revenue record.
- Property investors checking whether a sale falls on the right side of the 24-month long-term line.
- Brokers, contractors and site engineers who want a quick, reliable second opinion on their phone.
Why everything is free
Three reasons. First, the calculations cost us nothing to serve — they run in your browser, not on our server, so there is no per-user cost to recover. Second, charging for arithmetic that banks and revenue departments publish openly would be hard to justify. Third, a paywall would exclude exactly the people who benefit most: first-time buyers and small self-builders working to a tight budget.
There is no premium tier, no usage limit, and no feature deliberately held back.
What you get from using them
- Privacy. Nothing you type is transmitted, logged or stored. Every calculation happens locally.
- Speed. No frameworks, no trackers, no chart libraries. Pages load fast even on a weak mobile connection.
- Transparency. Every rate, factor and assumption is printed on the page and kept in clearly commented code.
- Context. Each tool explains its own formula, gives a worked example, and answers the questions people actually ask.
- Portability. Copy, download, print or share any result.
How we keep the tools honest
Rates change. State budgets revise stamp duty, the Union Budget revises capital gains rules, and material prices move constantly. Rather than pretend otherwise, we do three things: store every rate in one clearly labelled place so it can be updated quickly, print the assumptions on screen next to the result, and say plainly when a figure is indicative rather than final.
Where a calculation touches tax or law, we point you to a professional. A calculator is a starting point, not a substitute for advice.
Roadmap
We add tools rarely and carefully. Ideas currently under consideration:
- A rent versus buy comparison for Indian cities
- A home loan eligibility estimator based on income and existing obligations
- A loan prepayment and part-payment impact calculator
- A property registration document checklist by state
- A steel and TMT bar quantity estimator to sit alongside the cement calculator
- Hindi and regional language versions of the existing seven
If one of these would help you — or if something more useful is missing — tell us. Suggestions from people actually using the tools shape what gets built next.
