A short-term rental calculator helps investors estimate the income and profitability of properties listed on platforms like Airbnb and VRBO. By factoring in nightly rates, occupancy levels, cleaning fees, operating expenses, and mortgage payments, it provides a clear picture of monthly revenue, net operating income (NOI), and cash flow. This tool is essential for evaluating whether a property can produce strong returns, support financing, and outperform traditional long-term rentals. It enables investors to make informed decisions, compare properties, and understand the true earning potential of a short-term rental investment.
