Transparent methodology
Every result is calculated from the assumptions entered in your browser. RoomVilla does not store these calculator inputs. The tools provide planning estimates so you can compare options and ask better questions before speaking with a lender, authority, owner or qualified professional.
Principal × monthly rate × (1 + rate)ⁿ ÷ ((1 + rate)ⁿ − 1)
Principal is property value minus down payment; n is the number of monthly instalments.
Annual rent ÷ total property investment × 100
Net yield additionally deducts vacancy loss and annual owner-paid expenses.
Net operating income ÷ property value × 100
The calculation excludes loan payments, tax effects and assumed appreciation.
Property price ÷ applicable area
Carpet, built-up, super built-up and plot area must not be compared as if they are identical.
Rent + CAM + utilities + parking + other costs + applicable tax
The calculator also shows annual, per-person and effective per-square-foot costs.
Workspaces + rooms + support area + growth buffer
Building loading must be added when converting usable space to chargeable area.
Direct answers
EMI is calculated from the loan principal, monthly interest rate and number of monthly instalments. RoomVilla subtracts the entered down payment from the property value and applies the standard reducing-balance EMI formula.
Gross rental yield is annual rent divided by total property investment, multiplied by 100. Net rental yield further subtracts expected vacancy loss and annual owner-paid expenses.
Rental yield compares rent with total investment. Capitalisation rate compares net operating income with the property's value and normally excludes financing costs and appreciation.
The calculator uses the rate entered by the visitor because stamp duty and registration rules vary by state, buyer profile, property type and valuation basis. The applicable rate should be confirmed with the registration authority or a qualified professional.
There is no universal figure. The RoomVilla estimator starts with the area entered per person, then adds cabins, meeting rooms, support spaces and a growth buffer. Building loading or efficiency must be considered separately.
No. Results are planning estimates based only on the visitor's assumptions. Lending, taxation, title, measurement and transaction terms must be independently verified.
Editorial and calculation standard
Formula logic and explanatory content were reviewed by RoomVilla on 21 September 2026. State-specific duties, taxes, traditional area units, lending decisions and professional conclusions are intentionally left as visitor-controlled assumptions or marked for independent verification.
