Quick Answer: Revenue per unit measures the total income a property generates per unit (typically EGI divided by units). NOI per unit measures the operating profit per unit after expenses are deducted. Revenue per unit shows your top line; NOI per unit shows your bottom line at the property level. The spread between them reveals how efficiently the property converts revenue into profit.

What Is Revenue per Unit?
Revenue per unit (also called EGI per unit or income per unit) divides total effective gross income by the number of units. It measures a property's top-line earning capacity on a per-unit basis, enabling comparisons across properties of different sizes.
Example: $3,600,000 EGI ÷ 200 units = $18,000 per unit annually ($1,500/mo)
What Is NOI per Unit?
NOI per unit divides net operating income by total units. It measures the operating profit each unit contributes after all operating expenses are paid, and it is the primary metric for benchmarking property-level profitability across a portfolio.
Example: $2,160,000 NOI ÷ 200 units = $10,800 per unit annually ($900/mo)
Key Differences: NOI per Unit vs Revenue per Unit
| Factor | Revenue per Unit | NOI per Unit |
|---|---|---|
| What it measures | Top-line income per unit | Operating profit per unit |
| Expenses | Not deducted | Deducted |
| Market sensitivity | Primarily rent-driven | Rent and expense-driven |
| Benchmarking use | Revenue potential | Profitability and value |
| Valuation link | Indirect | Direct (NOI/unit × cap rate = value/unit) |
| Controllability | Moderate (market-dependent) | Higher (revenue + expense levers) |
When to Use Each Metric
Use revenue per unit when: Benchmarking rent levels against competitors, evaluating revenue growth trends, comparing top-line performance across properties in different markets, or assessing whether a property is capturing its fair share of market rent plus ancillary income.
Use NOI per unit when: Evaluating profitability across a portfolio, identifying properties with the best and worst operating efficiency, benchmarking against institutional standards, calculating per-unit property values, or making acquisition and disposition decisions.
How They Relate in Practice
Comparing both metrics across a portfolio reveals which properties are revenue leaders versus profit leaders — and they are not always the same. A Class A property may lead in revenue per unit ($22,000/year) but lag in NOI per unit ($11,000/year) because high-end amenities and staffing consume margins. A Class B property generating $16,000/year revenue might deliver $10,400/year NOI per unit with a leaner cost structure.
The ratio of NOI per unit to revenue per unit is the NOI margin in per-unit terms. Tracking this across properties highlights where expense control creates the most value and where revenue growth is being consumed by cost growth. Use our NOI calculator to model per-unit profitability, and see how BubbleGum BI's financial dashboards rank properties by both metrics so you can spot efficiency gaps instantly.
