Run the numbers before the meeting.
Four calculators that turn a builder's pitch into figures you can check and defend. Nothing is stored — everything runs in your browser.
Rent Compensation Estimator
Work out the monthly rent the builder should pay while you're out, and the total across the whole construction period — including the yearly step-up most agreements include.
Indicative only. Builders typically pay a fixed first-year rent with a yearly step-up — negotiate the escalation, not just the headline number.
Corpus Fund Calculator
A larger building costs more to run. Derive a corpus that genuinely covers your future maintenance, instead of accepting a round number the builder offers.
A defensible corpus covers the higher maintenance of a larger, lift-and- amenity building for a fixed horizon — derive it, don't accept a round number from the builder.
Carpet Area Gain Calculator
Turn a builder's headline percentage into the actual new carpet area of your flat — measured on RERA carpet, the only number that matters.
Always compare on RERA carpet, never built-up or super built-up. A 30% offer on carpet is a very different flat from 30% on built-up.
Redevelopment Timeline Planner
See a realistic month-by-month timeline for the whole project, with an honest buffer for the delays that almost always happen.
Base durations are typical Maharashtra ranges. The buffer is the honest bit - projects with a 0% buffer are the ones that overrun.
Editorial, not legal or financial advice. Consult your own advisors before deciding. Calculators are indicative and use simplifying assumptions; confirm specifics for your project with your PMC and advisors.
