Calculation method
Calculation method
Collected rent = potential rent × (1 − vacancy rate); NOI = collected rent + other income − operating expenses; cash flow = NOI − debt service.
Entered fixed decimals use exact rational arithmetic except the explicitly approximate IRR root. Money rounds only for display and supported nonzero amounts remain visible.
Worked example
Worked example
A 500,000 property with 60,000 rent, 5% vacancy, 3,000 other income, 20,000 expenses, and 25,000 debt service produces 15,000 cash flow.
Collected rent = potential rent × (1 − vacancy rate); NOI = collected rent + other income − operating expenses; cash flow = NOI − debt service.
Supported inputs
