Buyer Tools & Calculators
Four calculators built for Kolkata buyers, using current 2026 rates and real market inputs. Run the numbers before you sign — because a home is the biggest financial decision most people ever make, and rough estimates are how buyers get burned.
Total Cost Calculator
The developer's quote is only 82–86% of what you actually pay. Add stamp duty, GST, registration, parking, club, maintenance and mutation — see the honest all-in number before signing.
Carpet vs Super Built-Up
When a developer says "1,500 sqft", you typically get 1,050 sqft of walkable space. Convert between all three area types and see the real ₹/sqft on space you actually own.
Rent vs Buy
You're paying rent every month. Should that money be an EMI instead? Runs both scenarios year by year, factors tax benefits and property appreciation, returns your break-even year.
EMI Calculator
The exact monthly EMI, total interest and amortization schedule for a Kolkata home loan — with current 2026 rates from SBI, HDFC, ICICI and LIC HFL.
Why these tools exist
Most calculators online use rates that are two or three years out of date — some still apply the 2% pandemic-era stamp duty rebate (permanently discontinued July 1, 2024) or a women-buyer concession that West Bengal no longer offers. That single mistake can mislead a buyer by ₹2–3 lakhs on a mid-segment home.
These four calculators use rates verified against the West Bengal Directorate of Registration & Stamp Revenue in 2026, and reflect how homes are actually sold in Kolkata today: super built-up loading factors, mutation costs, developer add-ons and all.
