What is Net Operating Income?

Learn what Net Operating Income (NOI) is, how to calculate it, and which expenses to exclude for accurate business assessments.

KEY TAKEAWAYS

  • Net Operating Income (NOI) measures the profitability of core business operations before interest, taxes, depreciation, and amortization.

  • The formula is NOI = Total Revenue - Operating Expenses, excluding non-operating costs like taxes and debt.

  • Understanding NOI helps creative professionals track their true operational profitability without distractions.

What Is Net Operating Income (NOI)?

Net Operating Income (NOI) is a financial metric that measures the profitability of a business or investment property before accounting for interest, taxes, depreciation, and amortization. For creative professionals, NOI represents the income generated by the core activities of the business, helping you understand the true operational profitability.

Unlike net income, which includes non-operating items, NOI strips away financial noise so you can see how your core business is performing. Whether you're a podcaster selling subscriptions, a photographer booking client projects, or a writer earning royalties, NOI gives you a clear picture of how much your actual work is generating.

Net Operating Income (NOI) Formula & Calculation

The formula is straightforward: NOI = Total Revenue - Operating Expenses.

Total Revenue refers to income from creative work — podcast subscriptions, book sales, project fees, gallery earnings, or any other income directly tied to what you create or produce. Operating Expenses include the costs required to run your business, such as software subscriptions, office supplies, marketing, or travel for gigs.

The result is your NOI — a number that tells you whether your core operations are profitable before factoring in taxes, debt payments, or one-time expenses.

What's Not Included in Net Operating Income

Certain items are deliberately excluded from NOI because they are not considered part of core operational activity:

  • Income Taxes — These are based on net income, not operational performance, so they are excluded to keep NOI focused on operations.

  • Depreciation — A non-cash expense that represents the wear and tear of assets over time, not actual cash outflows from operations.

  • Debt/Interest Expenses — Financing costs are separate from operational performance and depend on how you choose to fund your business.

  • Tenant Improvements & Capital Expenditures — These are long-term investments in assets, not day-to-day operational costs.

By excluding these items, NOI gives you a cleaner, more accurate view of how your core business activities are performing financially.

Example of Net Operating Income (NOI)

Let's look at a practical example. A photographer earns $6,000 in total revenue: $5,000 from client projects and $1,000 from print sales. Their operating expenses total $750: gear rental ($300), editing software ($100), marketing ($200), and travel for gigs ($150).

NOI = $6,000 - $750 = $5,250. This $5,250 represents the photographer's true operational profit before any taxes, loan payments, or equipment depreciation are considered. It shows that the core photography business is healthy and generating strong returns from the actual work being done.

How It Applies to Your Business

When will you actually use this?

Net Operating Income isn't just for real estate investors. It's a powerful tool for anyone who wants to understand the true profitability of their core work. Here's how different creative professionals can apply it:
