Commercial lease calculator: escalation, CAM, total occupancy cost

Commercial leases in Noida and Greater Noida quote rent per sq ft per month with escalation every year or every three years, plus common area maintenance billed separately and 18% GST on both. Over a 9-year lease the escalations and CAM can exceed the headline rent. This tool totals the real occupancy cost.

How it is calculated

Rent steps up by the escalation percentage at the start of each escalation period; CAM is held flat (adjust if your CAM escalates too). Yearly cost = (rent + CAM) × area × 12, plus GST at 18% where the landlord is registered. Total occupancy cost adds the fit-out; the security deposit is shown separately because it is refundable.

Worked example

2,000 sq ft office at ₹60 + ₹12 CAM, 15% every 3 years, 9-year lease, 18% GST, ₹15 lakh fit-out: month-1 outflow ₹1.7 lakh; rent reaches ₹79 per sq ft in years 7–9; total occupancy cost about ₹2.23 crore including ₹31.7 lakh of GST, averaging ₹103 per sq ft per month all-in.
