Definition
Potential Gross Income (PGI) is the maximum possible income that a rental property could generate if it were fully occupied without any vacancies or collection losses. It assumes that all rental units are leased at prevailing market rates and that no tenants default on their rent.
Description
PGI does not account for operational expenses, vacancies, concessions, bad debt losses, or any other factors that might reduce the rental income collected by a property owner. It represents a best-case scenario for generating rental income and serves as a baseline for further financial analysis and projections.
Example
Consider a rental property with 10,000 square feet of rental space. If the average market rent is $24 per square foot:
10,000 square feet * $24 per square foot = $240,000 per year
In this scenario, the Property’s Potential Gross Income (PGI) is $240,000 annually. Note that:
- Concessional revenue such as an additional $5,000 from a ground floor shop is not included.
- A vacancy and collection allowance—say 5%—is not relevant to PGI.
Therefore, the PGI for the building in this example remains at $240,000 per year.
Frequently Asked Questions
What is the purpose of calculating PGI?
PGI helps property owners, investors, and analysts estimate the maximum income potential of a property. It serves as a base for deriving more realistic income projections accounting for potential losses and expenses.
How does PGI differ from Net Operating Income (NOI)?
While PGI measures the maximum potential income, NOI accounts for actual revenues received after subtracting vacancy allowances, operating expenses, and other deductions.
How can PGI affect property valuations?
A higher PGI can positively influence property valuations as it signals the gross income potential to investors and lenders, even though the actual future returns might involve adjusted projections considering operational realities.
Is PGI relevant for properties with mixed-use functionality?
Yes, PGI can be calculated separately for each income type (e.g., residential, retail, office) and then consolidated to reflect the total potential gross income for the mixed-use property.
Should property owners include additional income sources within PGI?
No, PGI should only reflect rental income at market rates under full occupancy conditions. Miscellaneous income such as leases for parking, signage, and other services are excluded.
- Net Operating Income (NOI): The income remaining after deducting operating expenses, vacancies, and collection losses from gross income.
- Effective Gross Income (EGI): PGI adjusted for estimated vacancy rates and collection losses, plus any additional income.
- Gross Scheduled Income (GSI): Similar to PGI, it represents anticipated rent revenue if the property were 100% occupied.
- Cap Rate: The capitalization rate representing the rate of return expected on a real estate investment property.

Real Estate Basics: Potential Gross Income Fundamentals Quiz
### What does Potential Gross Income (PGI) indicate about a property?
- [ ] The actual income received by the owner.
- [x] The maximum possible rental income assuming full occupancy.
- [ ] The adjusted rental income after accounting for vacancies.
- [ ] The amount after deducting all operational costs.
> **Explanation:** PGI represents the maximum rental income a property could achieve if it were fully occupied without any deductions for vacancies, rental concessions, or collection losses.
### When calculating PGI, should you include additional revenues like ground floor concession rents?
- [x] No, only rental income at market rates should be included.
- [ ] Yes, all forms of income should be included.
- [ ] Only if the concession rent exceeds certain thresholds.
- [ ] Sometimes, depending on local real estate regulations.
> **Explanation:** PGI focuses only on potential rental income from leasing property spaces at market rates; incidental revenues are excluded.
### What major factor is not accounted for in PGI calculations?
- [ ] Location
- [ ] Tenant quality
- [x] Vacancy
- [ ] Market rent
> **Explanation:** PGI assumes that there are no vacancies or collection losses and does not adjust for these factors.
### How does PGI differ from Effective Gross Income (EGI)?
- [ ] PGI includes vacancy, while EGI does not.
- [ ] EGI excludes miscellaneous income, while PGI includes it.
- [x] PGI is the total potential income from rents, whereas EGI reflects actual expected cash flow after adjusting for vacancies and losses.
- [ ] Both terms refer to the same income measure on the balance sheet.
> **Explanation:** PGI is the theoretical maximum rental income, while EGI includes adjustments for vacancies, losses, and additional income sources.
### Who is most likely to use PGI calculations in real estate?
- [x] Property investors and analysts
- [ ] Municipal corporations
- [ ] Lawyers
- [ ] Event planners
> **Explanation:** Property investors, owners, and analysts use PGI to evaluate income potential and assess the profitability of a property.
### How can calculating PGI help in determining property value?
- [ ] By exaggerating the operational expenditures.
- [x] By providing a base income estimate for comparing with actual performance and computing investment returns.
- [ ] By ensuring accurate tenant history records.
- [ ] By outlining the current property tax rates.
> **Explanation:** PGI offers a primary guideline income figure that helps in projecting potential returns, influencing decision-making and property valuation.
### Why does PGI not account for collection losses?
- [x] It is purely a theoretical measure of potential revenue.
- [ ] Collection losses can vary widely and thus impact PGI.
- [ ] It always includes collection losses inherently.
- [ ] PGI is meant to project exact net revenue.
> **Explanation:** Because PGI is an idealistic representation of income, it does not consider collection losses or any operational inefficiencies.
### Which is a more realistic measure of a property’s income than PGI?
- [x] Net Operating Income (NOI)
- [ ] Potential Gross Rent (PGR)
- [ ] Property Valuation Assessment (PVA)
- [ ] Immediate Income Total (IIT)
> **Explanation:** NOI provides a realistic measure as it takes operating expenses, vacancies, and other necessary deductions into account.
### If a property has a high PGI but experiences significant vacancies and collection issues, what real estate term reflects this adjusted scenario?
- [ ] Further Potential Gross Income
- [x] Effective Gross Income (EGI)
- [ ] Unadjusted Gross Income
- [ ] Raw Rental Output
> **Explanation:** EGI adjusts PGI by accounting for actual vacancies, losses, and additional income sources, presenting a clearer picture of expected cash flow.
### How does a vacancy rate impact PGI?
- [ ] It increases PGI as more units remain open.
- [x] It does not directly impact PGI calculations.
- [ ] It is added to PGI for better estimates.
- [ ] It exacts monthly adjustments on PGI.
> **Explanation:** PGI assumes full occupancy and thus does not regard vacancy rates; it reflects a property’s potential income in an ideal condition.
