What Is Effective Gross Income (EGI)?
Effective Gross Income (EGI) is the realistic, income-producing potential of an income property after accounting for typical income shortfalls. In simple terms:
EGI = Potential Gross Rental Income + Other Income − Vacancy & Credit Losses
EGI is the first “after-realities” line on an investment property’s pro forma. It converts the theoretical maximum income into a usable revenue figure an investor can rely on when determining cash flow, net operating income (NOI), valuation (cap rate), underwriting, and investment decisions.
Why EGI Matters
– Provides a realistic starting point for cash‑flow analysis — not just optimistic maximum rent.
– Feeds directly into NOI and valuation: NOI = EGI − Operating Expenses; Cap rate = NOI / Purchase Price.
– Helps underwriters and lenders evaluate debt service coverage and loan risk.
– Enables scenario planning (best/base/worst) for vacancy, collections, and pricing changes.
Core Components (with practical notes)
1. Gross Potential Rental Income (GPRI)
– Definition: The total rental income if every unit is rented at the full lease/rent amount for the entire period (usually 12 months).
– How to compute: Sum each unit’s full annual rent. For multi-unit: GPRI = (Monthly rent per unit × 12) × number of units (or sum by unit if rents differ).
– Practical note: Use market rent if planning to reprice units at market on acquisition; use current contract rents if evaluating actual cash flow today.
2. Other Income
– What it includes: Recurring ancillary income tied to the property, such as laundry/vending, parking fees, storage rents, pet rents, utility reimbursements, late fees, and application or admin fees (amortized if you want a recurring-year view).
– Practical note: Only include recurring or reliably collectible items. For one‑time fees (e.g., application), consider amortizing them across the year or excluding them from conservative pro formas.
3. Vacancy Costs
– Definition: Expected loss of rent because units go unrented between tenants.
– How to estimate: Use historical property vacancy data if available; otherwise use local market vacancy rates (by property type and submarket) or conservative industry rules of thumb. Express as a percentage of potential income.
– Practical note: Account for turnover time, lease-up timelines for newly renovated units, and seasonality.
4. Credit (Collection) Losses
– Definition: Income lost when tenants fail to pay rent, pay late, or pay only partially.
– How to estimate: Evaluate historical collection rates, industry averages, and the tenant screening/management quality. Often combined with vacancy into a single “vacancy & credit loss” percentage.
– Practical note: Differentiate between short-term late payments (recoverable) and long-term bad debt (write-offs).
EGI Formula — Practical Version
Step 1: Calculate Potential Gross Income (PGI) = Gross Potential Rental Income + Other Income
Step 2: Estimate Vacancy & Credit Losses (as $ or % of PGI)
Step 3: EGI = PGI − Vacancy & Credit Losses
Numeric Example (step‑by‑step)
Scenario: 10-unit building, varying rents, and ancillary income.
1. Gross Potential Rental Income:
– 10 units × $1,200/month × 12 months = $144,000
2. Other Income:
– Laundry + parking + storage = $6,000/year
3. PGI = 144,000 + 6,000 = $150,000
4. Vacancy & Credit Losses:
– Assume combined rate 7% (5% vacancy + 2% credit) → 150,000 × 7% = $10,500
5. EGI = 150,000 − 10,500 = $139,500
How EGI Feeds the Valuation Chain
– Net Operating Income (NOI) = EGI − Operating Expenses (insurance, property taxes, maintenance, management, utilities paid by owner, etc.)
– Cap Rate = NOI / Purchase Price (market valuation metric)
– Debt Service Coverage Ratio (DSCR) = NOI / Annual Debt Service (used by lenders)
Practical Steps to Calculate and Use EGI (Checklist)
1. Gather data
– Current rent roll (unit-level rent, lease start/end), historical collection and vacancy records, and ancillary income statements.
– Local market vacancy rates and comparable rents.
2. Determine GPRI
– Choose whether to use current contract rents or market rents for prospective valuation.
3. List and quantify other income
– Include only reliable, recurring sources; amortize one-time fees if included.
4. Estimate vacancy & credit loss
– Use the higher of historical property loss or comparable market rate; consider adding a premium for renovations or riskier tenant pools.
5. Compute PGI and subtract vacancy & credit loss → EGI
6. Subtract operating expenses → NOI
7. Run scenarios
– Create base, conservative, and aggressive scenarios (e.g., vacancy at 3%, 7%, 12%) to see sensitivity.
8. Use EGI-based metrics for decisions
– Compare NOI and cap rate to market comps, calculate DSCR for potential financing, and evaluate cash-on-cash returns.
Tips to Improve or Protect EGI
– Reduce vacancy: proactive marketing, competitive rents, quick turnover repairs, lease renewal incentives.
– Increase other income: add paid parking, storage, upgraded laundry, pet fees, or utility pass-throughs.
– Improve collections: require electronic payments, implement clear late-fee policies, screen tenants, require security deposits.
– Upgrade units to command higher market rents (value-add renovations).
– Manage seasonality: time advertising and lease expirations to reduce vacancy risk.
Common Pitfalls and Limitations
– Overreliance on GPRI: using full-market potential rent without realistic vacancy or collection expectations inflates revenue.
– Ignoring one-time or non-recurring income: these can skew a single-year EGI upward and give a false sense of sustainable revenue.
– Applying inconsistent bases: ensure vacancy & credit loss percentages are applied to the same PGI basis used for other items.
– Not stress-testing assumptions: small changes in vacancy or rent growth materially affect NOI and valuation.
Quick Templates (what your calculation should include)
– Column list for a simple spreadsheet: Unit ID | Current Rent | Market Rent | Annual Rent | Other Income (per unit or property) | Total PGI | Vacancy & Credit % | Vacancy $ | EGI
– Follow-on columns: Operating Expenses (line items) | NOI | Purchase Price | Cap Rate | Annual Debt Service | DSCR
Final Notes
Effective Gross Income is a practical, investor‑oriented figure that takes a property’s theoretical income and adjusts it for the real-world frictions of vacancies and unpaid rent. It’s a critical early step in underwriting, valuation, and operational planning. Use historical performance where possible, default to local market data when not, and always model multiple scenarios to understand upside and downside risk.

Why EGI Matters for Valuation and Cash Flow Analysis
– EGI is the starting point for most income-based property valuation methods. After you calculate EGI, you subtract operating expenses (taxes, insurance, maintenance, management fees, utilities, etc.) to get Net Operating Income (NOI). Lenders and investors use NOI to assess debt service coverage, and appraisers use NOI together with a capitalization rate (cap rate) to estimate market value.
– Simple chain: Potential Gross Income (PGI) → add Other Income → subtract Vacancy & Collection Losses = Effective Gross Income (EGI). Then EGI − Operating Expenses = NOI. NOI ÷ Cap Rate ≈ Market Value.
EGI Formula (recap)
– EGI = Potential Gross Income (PGI) + Other Income − Vacancy & Collection Losses (vacancy + credit losses)
– Notes:
– Vacancy & collection losses are often expressed as a percentage of PGI (or PGI + other income). Be consistent in your convention and document which base you use.
– “Other income” includes recurring income sources (parking, laundry, late fees) and sometimes one-time but predictable sources (storage rentals, vending commissions).
Step-by-step Practical Guide to Calculating EGI
1. Determine the Property’s PGI
– Multiply each unit’s market rent by the number of months it is expected to be rented (usually 12 months for annual PGI), then sum across units.
– Example: 4 units × $1,000/month × 12 months = $48,000 PGI.
2. Add Other Income
– List all recurring ancillary income and estimate annual amounts.
– Example: Laundry $1,200 + Parking $600 + Storage $400 = $2,200 Other Income.
3. Estimate Vacancy & Collection Losses
– Use historical occupancy, local market statistics, or benchmarking services to pick a realistic vacancy rate.
– Separate credit (collection) loss if you track it independently; otherwise combine as one vacancy & collection loss percentage.
– Example: Choose 5% vacancy & collection loss on PGI: 5% × $48,000 = $2,400.
4. Compute EGI
– EGI = PGI + Other Income − Vacancy & Collection Losses
– Using the example above: EGI = $48,000 + $2,200 − $2,400 = $47,800.
5. Proceed to NOI
– Subtract operating expenses from EGI to get NOI. This is used for valuation and underwriting.
Two Examples (worked)
Example A — Single-Family Rental
– PGI: $2,000/month = $24,000/year
– Other Income: $0 (no ancillary income)
– Vacancy & Collection Losses: 7% (market has higher turnover) → 7% × $24,000 = $1,680
– EGI = $24,000 − $1,680 = $22,320
– If operating expenses total $8,320/year → NOI = $22,320 − $8,320 = $14,000
Example B — Small 4-Unit Apartment
– Unit rents: 2 × $900, 1 × $1,100, 1 × $950 → monthly total $3,850 → PGI = $3,850 × 12 = $46,200
– Other Income: Laundry $1,000 + Parking $800 = $1,800
– Vacancy & Collection Losses: Historical vacancy 4% on PGI → 0.04 × $46,200 = $1,848
– EGI = $46,200 + $1,800 − $1,848 = $46,152
– If operating expenses = $18,152 → NOI = $28,000
– If local market cap rate = 6% → Implied value ≈ NOI ÷ cap rate = $28,000 ÷ 0.06 = $466,667
How to Estimate Vacancy & Collection Losses Realistically
– Use your property’s historical occupancy and collection data if available.
– Benchmark against local market vacancy rates from sources such as local MLS, brokers, or market research reports.
– Adjust for property type, location, seasonality, and lease terms (short-term/stabilized vs. new or renovated properties).
– For conservative underwriting, use slightly higher loss assumptions than historical to allow a buffer.
How Lenders and Investors Use EGI
– Lenders typically start with EGI to determine Debt Service Coverage Ratio (DSCR): NOI ÷ Annual Debt Service. If NOI (derived from EGI) is too low relative to debt service, loan terms will be limited.
– Investors use EGI to model cash flow, stress-test vacancy scenarios, and compare competing investments on a cash-on-cash or cap-rate basis.
– Appraisers may adjust vacancy allowances to reflect market norms when reconciling an income approach.
Practical Steps to Improve EGI (Actionable Tips)
– Increase PGI: Raise rents to market levels at lease turnover; add value through renovations that justify higher rents.
– Add Other Income Streams: Install coinless laundry, rent storage, add covered parking spaces, charge pet or amenity fees (in compliance with laws).
– Reduce Vacancy: Offer lease incentives that reduce turnover time (e.g., pre-marketing available units), improve tenant retention with responsive management, provide flexible lease terms that attract stable tenants.
– Reduce Collection Losses: Implement thorough tenant screening, use automated rent collection tools, apply late fees consistently, and enforce lease terms while balancing tenant relations.
– Monitor and Adjust: Regularly review actuals vs. forecasts and update vacancy/collection assumptions based on recent performance.
Common Mistakes and Pitfalls
– Overestimating occupancy or PGI: Using rents above market or assuming full-year occupancy without evidence.
– Ignoring seasonal factors or local market cycles that affect vacancy.
– Applying the vacancy rate to the wrong base (e.g., applying it only to PGI when other income is significant).
– Forgetting non-rental recurring income or one-time known items when projecting income.
– Using a single static scenario—always run sensitivity analyses (best, expected, worst cases).
Sensitivity Analysis — Quick Example
– Baseline EGI from Example B = $46,152
– If vacancy rises to 8% instead of 4%: Vacancy loss = 0.08 × $46,200 = $3,696 → EGI = $46,200 + $1,800 − $3,696 = $44,304 (drop of $1,848)
– Impact on NOI and valuation can be significant—always examine multiple vacancy scenarios.
Regulatory and Accounting Notes
– For financial reporting and underwriting, be transparent about what constitutes “other income” and whether vacancy losses are projected on PGI or PGI + other income.
– Taxable income reporting follows tax code rules; EGI is an analytical metric for investors and appraisers and not a tax filing line item.
FAQ (brief)
– Q: Should I include nonrecurring income (e.g., one-time repair reimbursements) in Other Income?
– A: Generally no. Include only predictable, recurring income sources. One-off items are better treated separately or excluded from forward-looking EGI.
– Q: Is EGI the same as revenue on the income statement?
– A: EGI is an analytical measure of expected gross rental receipts after realistic vacancy/collection adjustments. Revenue reported for tax or accounting purposes may differ due to timing, recognition rules, and one-time items.
Concluding Summary
Effective Gross Income (EGI) is a foundational metric for rental property investors, acting as the bridge between theoretical maximum rents (PGI) and realistic income expectations after accounting for vacancy and collection losses and including ancillary income. Calculating EGI carefully—and basing vacancy and collection assumptions on historical performance and market benchmarks—gives investors and lenders a clearer picture of potential cash flow. From EGI you derive NOI, evaluate loan capacity and cap-rate-based valuations, and run sensitivity analyses to understand downside scenarios. Regularly update assumptions, pursue practical ways to raise PGI and other income, and manage vacancy and collection risk to strengthen EGI and the overall investment case.
