How to use it
- Gross Annual Rent — independent among the net operating income fields — changing it alone moves the result.
- Vacancy Rate — used once on net operating income, and worth a second glance if the output looks off.
- Operating Expenses — the Finance field that most often arrives from another document; re-check its scale.
- Compare the result from Net Operating Income Calculator with the figures above it; the intermediate values are where a wrong unit usually shows up first.
- Switch one field at a time in Net Operating Income Calculator and note the change each time; that short list of movements is a sensitivity check you can explain.
The formula behind the result
The formula in Net Operating Income Calculator operates on the values exactly as entered; keeping the units shown in each label is what makes the result trustworthy.
Worked example: with gross annual rent of 120,000, vacancy rate of 5, operating expenses of 42,000, this net operating income calculation returns NOI: $72000. The same run reports Effective gross income: $114000 | NOI excludes mortgage payments — that is why cap rates work across differently.
The steps it follows:
- Effective income = $120,000 × (1 − 0.05) = $114000.00
- NOI = $114000 − $42,000 = $72000
- Opex includes taxes, insurance, maintenance, management, and utilities — but not the mortgage
