Monthly rent × 12
Annual Rent × Vacancy Rate% (income lost to expected vacant periods)
Sum of annual maintenance, property tax, insurance, and other recurring costs
Original property acquisition cost
Gross rental yield gives a quick headline return relative to purchase price, but ignores costs. Net rental yield deducts expected vacancy losses and all recurring ownership expenses (maintenance, tax, insurance) to reveal the real cash yield a landlord actually earns — the standard, more reliable metric for judging whether a rental property is a good income investment.
Below 2% is considered low, 2-4% average, 4-6% good, and above 6% is considered excellent for Indian residential rental properties — commercial properties typically yield higher.
Net yield subtracts real recurring costs (vacancy, maintenance, tax, insurance) that gross yield ignores entirely, so net yield always gives a more conservative and realistic picture of actual returns.
