About this calculator
The Vacancy Impact on Income calculator estimates effective income from property or real estate investment funds (REITs) by applying a vacancy rate. The formula used is (1 - v) × potential income, where 'v' is the vacancy rate. For example, a 20% vacancy rate would result in 80% of the expected income. This tool is useful for assessing income risk in real estate investments.
The vacancy rate represents the period a property remains unoccupied, directly affecting financial returns. This calculator considers only the relationship between vacancy and income, excluding operational costs. It is ideal for initial simulations, but combining it with metrics like maintenance costs and interest rates provides a more realistic analysis.
Use this calculator before investing in REITs or residential/commercial properties. It helps predict scenarios where occupancy is less than 100%, such as during economic crises or seasonal fluctuations. It is also helpful for portfolio managers comparing properties with different vacancy rates.
Note: the formula does not account for factors like property depreciation, marketing costs to rent out, or late fees. For deeper analysis, consult finance and real estate specialists.
