Effective gross revenue (EGR) is a property's potential gross income plus other income, less an allowance for vacancy and credit loss. It represents the realistic total revenue a property is expected to collect in a year before any operating expenses are deducted, and it serves as the top line from which net operating income is calculated.
What effective gross revenue means
Effective gross revenue describes the money a property actually expects to collect, as opposed to the money it could collect in a perfect world. Every building has a theoretical revenue ceiling, the amount it would earn if every space were leased at market rent and every tenant paid in full and on time. Real estate rarely works that way, so EGR adjusts the theoretical figure down for empty space and uncollected rent, then adds the other income a property earns beyond base rent. The result is a grounded, realistic revenue number.
This realism is what makes EGR so useful. A pro forma built on the theoretical maximum will always look better than the property will ever perform, and decisions made on that inflated number tend to disappoint. EGR brings the revenue picture back to earth by acknowledging that some space sits vacant between tenants and that a portion of billed rent is never collected. It then recognizes that parking, signage, fees, and reimbursements are genuine revenue that belongs in the total.
Because EGR sits directly above operating expenses in the income statement, it is the figure that feeds net operating income. Get EGR right and the rest of the analysis rests on solid ground. Overstate it, and every figure built on top, including value, becomes optimistic.
It helps to think of EGR as the bridge between the leasing side of a property and its financial statements. The rent roll, lease terms, and occupancy describe what the building has contracted to earn, while EGR converts that contractual picture into the revenue the property will plausibly realize once normal losses are accounted for. That bridging role is why analysts spend so much effort getting EGR right: it is the first point at which raw leasing data becomes a financial figure that drives valuation, and an error introduced here travels through every calculation that follows.
Why effective gross revenue matters in commercial real estate
EGR matters because it is the realistic revenue base for everything downstream. Net operating income is calculated by subtracting operating expenses from EGR, and value is then derived from NOI. A revenue figure that is too high cascades through the entire analysis, producing an NOI and a valuation that the property cannot actually support. Investors who skip the discipline of a realistic EGR often overpay, while those who build it carefully protect themselves from disappointment.
The figure also reveals the quality of a property's income, not just its quantity. Two buildings might report similar potential gross income, but the one with lower vacancy and stronger collections will show a higher EGR and a healthier operation. By forcing an explicit assumption about vacancy and credit loss, EGR makes the difference between a stable, well-occupied asset and a shakier one visible on a single line. That transparency is valuable to lenders and buyers who want to understand risk, not just headline rent.
For operators, EGR is a target they can influence directly. Reducing vacancy by leasing space faster, tightening collections to lower credit loss, and capturing more other income all raise EGR without changing a single contractual rent. A manager who turns over a vacant suite a month sooner, or who recovers more of the parking and reimbursement income a property is owed, lifts the revenue base in a way that flows straight through to NOI and value. EGR connects those operational wins to the financial outcomes ownership cares about.
Across a portfolio, a consistent EGR definition lets an owner compare assets fairly. Whether the property is an office, a retail center, or an industrial building, the same logic of potential income, less losses, plus other income, applies. That common structure makes EGR a dependable building block for portfolio-level reporting.
The composition of EGR also tells a story about an asset's resilience. A property whose revenue leans heavily on a handful of large tenants carries more concentration risk than one with a diverse rent roll, even if both report the same EGR. A building that earns a meaningful share of its revenue from reliable other income, such as long-term parking contracts or expense reimbursements, may hold up better through a leasing downturn than one dependent almost entirely on base rent. Reading EGR with an eye to where the revenue comes from, not just how large it is, helps an owner judge how steady that revenue is likely to be when conditions tighten.
How effective gross revenue is built
EGR is assembled step by step, starting from the revenue ceiling and adjusting toward reality. Each step has a clear purpose.
1. Start with potential gross income
Begin with the rent the property would collect if fully leased at market rates. This is the theoretical maximum, sometimes called gross potential rent, and it sets the starting point.
2. Subtract vacancy loss
No building stays perfectly full. Subtract an allowance for space expected to be unoccupied during the year, whether from turnover, lease-up, or soft demand.
3. Subtract credit loss
Some tenants pay late or default. Subtract an allowance for rent that is billed but realistically will not be collected, which keeps the figure honest about collections.
4. Add other income
Add revenue earned beyond base rent, such as parking, storage, signage, late fees, and expense reimbursements. Combining these with adjusted rental income produces effective gross revenue.
Stated simply, EGR equals potential gross income, less vacancy and credit loss, plus other income. The judgment lies in setting realistic loss allowances and counting the right sources of other income.
Key takeaways
- EGR equals potential gross income, less vacancy and credit loss, plus other income.
- It is the realistic revenue base from which operating expenses are subtracted to reach net operating income.
- Reducing vacancy, tightening collections, and capturing other income all raise EGR without changing contractual rent.
What goes into effective gross revenue
EGR draws on a few distinct categories, and classifying each one correctly keeps the figure reliable.
Base rental income is the contractual rent tenants owe under their leases and forms the largest component for most properties. Other income covers the many smaller streams a property earns, and getting it right often separates a thorough analysis from a sloppy one. Vacancy and credit loss are the offsetting deductions that turn potential income into realistic income.
Typical sources of other income that belong in EGR include:
- Parking and storage, from monthly permits, hourly fees, or reserved spaces.
- Expense reimbursements, such as recoveries for common area maintenance, taxes, and insurance.
- Signage and antenna income, from rooftop or facade licenses.
- Service and amenity fees, including conference rooms, after-hours HVAC, or amenity access.
- Late fees and miscellaneous charges, which recur in normal operations.
Counting these sources accurately, while applying realistic vacancy and credit allowances, is what makes one property's EGR genuinely comparable to another's.
A worked example
The table below shows an illustrative one-year EGR calculation for a midsize multi-tenant building. The figures are hypothetical and rounded to make the structure clear rather than to model any specific market.
| Line item | Illustrative amount |
|---|---|
| Potential gross income (rent at full occupancy) | 3,000,000 |
| Less vacancy loss | (210,000) |
| Less credit loss | (60,000) |
| Plus parking and amenity income | 180,000 |
| Plus expense reimbursements | 240,000 |
| Effective gross revenue | 3,150,000 |
In this example, the property starts from a 3,000,000 dollar revenue ceiling, gives up 270,000 dollars to vacancy and credit loss, and adds 420,000 dollars of other income, arriving at an effective gross revenue of 3,150,000 dollars. That figure becomes the top line of the income statement. Subtracting operating expenses from it would produce net operating income, which is why a realistic EGR is so important to every figure that follows.
Best practices for working with EGR
Teams that produce reliable EGR ground their vacancy and credit assumptions in evidence rather than optimism. They look at the property's own history, current lease expirations, and local market conditions to set loss allowances they can defend, instead of plugging in a hopeful number to make a deal pencil. They also capture every legitimate source of other income, since revenue that is owed but never billed quietly suppresses both EGR and NOI.
Strong operators treat EGR as a figure to manage, not just report. They monitor vacancy and collections through the year so the actual result tracks the assumption, and they investigate gaps between billed and collected revenue before credit loss accumulates. Reviewing EGR alongside the rent roll and other income detail keeps the components honest, and it gives ownership confidence that the realistic revenue base, and the NOI built on it, rests on sound and repeatable inputs.
One pitfall deserves particular attention: the gap between billed and collected revenue. A property can show strong billings while quietly accumulating receivables that may never be paid, and if credit loss is not recognized honestly, EGR overstates the revenue the property will actually realize. Disciplined teams reconcile billed rent against cash received on a regular cadence, age their receivables, and adjust the credit loss assumption when the evidence calls for it. This habit keeps EGR aligned with the money that genuinely arrives, which is the only revenue that ultimately supports value, debt service, and distributions to ownership.
Frequently asked questions
What is the formula for effective gross revenue?
Effective gross revenue equals potential gross income plus other income, less an allowance for vacancy and credit loss. It captures the realistic total revenue a property collects before operating expenses are subtracted.
What is the difference between potential gross income and effective gross revenue?
Potential gross income assumes full occupancy and complete collection at market rent. Effective gross revenue adjusts that figure for real-world losses from vacancy and uncollected rent, then adds other income, producing a realistic revenue base.
Is effective gross revenue the same as effective gross income?
In most contexts the two terms are used interchangeably. Both describe potential gross income plus other income, less vacancy and credit loss, and both serve as the revenue line from which operating expenses are deducted to reach net operating income.
Why does effective gross revenue matter?
Effective gross revenue is the realistic revenue base for a property. Net operating income is calculated by subtracting operating expenses from it, so an accurate EGR is essential for valuing and underwriting commercial real estate.
