Use this calculator to assess a residential or commercial property before you commit. It separates headline rental yield from income after vacancy, service charges, maintenance, management costs and financing.
Enter your own figures. The prefilled values are illustrative assumptions, not asking prices, achieved rents or market forecasts for any specific Dubai community.

Scenario testing
These are mechanical sensitivities, not market forecasts. Conservative assumes rent -10%, vacancy +3 points, expenses +10% and appreciation -1 point. Upside assumes rent +10%, vacancy -2 points, expenses -5% and appreciation +1 point. You can change the underlying deal assumptions above.

Important: Results are educational estimates based entirely on the inputs you provide. They are not verified market prices or rents and cannot guarantee occupancy, financing, appreciation or resale. Mortgage payments assume a fully amortising loan with equal monthly payments. Taxes and fees not entered are excluded. This tool is not investment advice.
Results update automatically. Your inputs are not saved or sent to the server.
Enter a purchase price and rent above zero, and check vacancy, LTV and interest-rate ranges.
What the calculator measures
- Gross rental yield: potential annual rent divided by the purchase price, before vacancy and expenses.
- Effective yield: rent remaining after the vacancy allowance, divided by the purchase price.
- Net operating yield: net operating income after vacancy and entered operating costs, divided by total acquisition cost.
- Cash-on-cash return: annual cash flow after estimated mortgage payments, divided by the initial cash equity.
- Exit analysis: an illustrative sale value, selling costs and remaining loan balance at the end of the selected holding period.
How to use it properly
Start with a realistic rent supported by comparable, achieved leases rather than asking rents. Enter the actual service charge and a vacancy allowance that reflects the building, unit type and tenant market. Add maintenance, insurance, management and transaction costs. Only enable the mortgage option when you have a credible financing assumption.
The Conservative, Base and Upside cases are sensitivity tests. They change selected assumptions to show how exposed a deal may be; they are not forecasts. A result is only as reliable as the inputs behind it.
Important limitations
The calculator runs in your browser. It does not save or transmit your inputs. It does not retrieve live DLD transactions, current market rents, mortgage offers, tax advice or project-specific service charges. Financing is estimated using a standard amortising-loan formula. Taxes, legal costs and other items are excluded unless entered manually. Use transaction documents and independent professional advice before making an investment decision.
