What does the page calculator do?
NOI Calculator works out the noi from the Gross Rental Income, Vacancy & Losses, and Operating Expenses, following standard Finance conventions — the page defaults produce a noi of $60,000/yr.
- Inputs: Gross Rental Income, Vacancy & Losses, and Operating Expenses.
- Output: the noi, plus the intermediate steps behind it.
- Method: the standard Finance formula, evaluated entirely in your browser.
Quick answer
With the default inputs (gross rental income of 100,000, vacancy & losses of 5, operating expenses of 35,000), noi calculator returns a noi of $60,000/yr. Assumptions and limits are summarized below.
How does it work?
NOI Calculator computes the noi directly from your inputs — the Gross Rental Income, Vacancy & Losses, and Operating Expenses feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
How it works
This page is a working noi calculator: enter your values, read the figure, and follow the step list to see exactly how the answer was derived.
How to use it
- Gross Rental Income — one of the values the calculation builds from; the result reflects exactly what you type here.
- Vacancy & Losses — used in the first stage of the calculation, so entering it accurately matters more than any later refinement.
- Operating Expenses — a core input the formula applies directly — keep the units consistent with the label.
- The output panel in noi calculator leads with the headline result and follows with the steps behind it, so the value can be checked rather than assumed.
- Adjust and re-run. Change one input at a time to see how sensitive the noi is to it — the fastest way to understand what the calculation is doing.
The formula behind the result
The calculation in NOI Calculator applies the standard Finance method, keeping full precision internally and rounding only the final display.
Worked example: with gross rental income of 100,000, vacancy & losses of 5, operating expenses of 35,000, this noi calculation returns NOI: $60,000/yr. The same run reports Effective gross income: $95,000 | Cap rate at 8% value: 750,000.
The steps it follows:
- Formula: NOI = Gross Rent × (1 − vacancy) − Operating Expenses
- Effective gross = $100,000 × 0.95 = $95,000
- NOI = $95,000 − $35,000
- NOI = $60,000
Substitute your own values and the same steps produce your answer — that is the point of a calculator that shows its working.
Understanding the result
The noi is the headline answer; the supporting figures beneath it and the step list give the surrounding context needed to judge it.
Where it helps
NOI Calculator fits planning and checking: short-term planning, comparing scenarios side by side, and double-checking a figure before acting on it, or any moment when the result needs to be right the first time.
Common mistakes
The most common error with NOI Calculator is a unit mismatch — one value entered in different units than its label assumes quietly skews the noi. Check each label before typing.
Tip: Run NOI Calculator twice with deliberately low and high inputs; the spread tells you how sensitive the output is, which a single run never shows.
Assumptions and limitations
NOI Calculator assumes the units shown in each label — entering values in different units will skew the noi proportionally.
Why use this calculator
Because it is fast and private — NOI Calculator runs entirely in your browser, nothing is uploaded, and no account is needed.

Frequently Asked Questions
What does the tool calculate?
NOI Calculator turns the values you enter into a verified noi — the formula, every intermediate step, and the assumptions sit beside the result instead of hidden behind it. Because the page doubles as documentation: NOI Calculator puts the formula, a worked example, and the assumptions right beside the calculator.
How is the result calculated?
The first steps are formula: noi = gross rent × (1 − vacancy) − operating expenses, then effective gross = $100,000 × 0.95 = $95,000. NOI Calculator substitutes the Gross Rental Income, Vacancy & Losses, and Operating Expenses into the formula, evaluates it in the order shown in the steps panel, and reports the figure rounded for readability.
What do I need to use the NOI Calculator?
The Gross Rental Income, Vacancy & Losses, and Operating Expenses it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the noi instantly.
What does the result from the tool mean?
The main number the noi calculator returns is the noi for your exact inputs, and the supporting figures and step list give it context. The model behind NOI Calculator covers the standard case; special cases, edge values, or jurisdiction-specific rules may need manual adjustment.
When is the page most useful?
Typical uses for NOI Calculator include short-term planning, comparing scenarios side by side, and double-checking a figure before acting on it — anywhere the figure needs to be defensible rather than guessed. Run NOI Calculator twice with deliberately low and high inputs; the spread tells you how sensitive the result is, which a single run never shows.
