Transparent tools for short-term rental deal math.
Model cash flow, returns, financing, and operating costs with assumptions you can inspect and change.
How the Tools Work
STR Numbers organizes common short-term rental underwriting inputs: purchase and financing terms, nightly rate, occupancy, platform fees, operating expenses, and upfront cash.
The calculators apply visible formulas to the assumptions you enter, then show outputs such as cash flow, cap rate, cash-on-cash return, and break-even occupancy. City averages are starting assumptions, not live market forecasts, and should be replaced with property-specific research.
Results are educational estimates rather than investment, tax, lending, or legal advice. A useful analysis checks a conservative case, includes the full cost stack, and confirms local rules before a decision.
