Why It Matters
FFO tells you how much operating cash a REIT generates from its properties, stripped of accounting distortions. Net income is misleading for real estate companies because GAAP requires them to depreciate buildings even as property values rise. FFO corrects for this, making it the go-to metric for comparing REIT performance and evaluating whether distributions are sustainable.
At a Glance
- Standard profitability metric for REITs, defined by NAREIT
- Formula: FFO = Net Income + Depreciation + Amortization − Gains on Property Sales
- More reliable than net income for real estate operating performance
- Reported per share (FFO per share) for easy comparison
- Used to assess dividend sustainability and REIT valuation
- Basis for the more refined AFFO metric
FFO = Net Income + Depreciation + Amortization − Gains on Property Sales
How It Works
GAAP accounting requires companies to depreciate buildings over time—typically 27.5 years for residential real estate and 39 years for commercial. For most businesses, depreciation reflects real economic wear-and-tear. For real estate, though, buildings often appreciate in value while GAAP shows them shrinking on paper. This creates a gap between reported net income and actual cash performance.
FFO was created by NAREIT (the National Association of Real Estate Investment Trusts) to bridge that gap. The calculation starts with net income, then adds back depreciation and amortization since those charges don't represent actual cash leaving the business. It also removes gains from property sales, because selling a building is a one-time event—not a sign of ongoing operational strength.
The formula is straightforward:
FFO = Net Income + Depreciation + Amortization − Gains on Property Sales
REITs report FFO per share alongside traditional earnings-per-share figures. Analysts and investors use the FFO payout ratio—distributions divided by FFO—to judge whether a REIT can maintain its dividends. A payout ratio under 80% is generally considered healthy; anything above 100% signals the REIT is paying out more than it earns from operations.
For a deeper look at distributable income, investors often turn to AFFO (Adjusted FFO), which takes FFO a step further by subtracting recurring capital expenditures and straight-line rent adjustments. AFFO is considered an even closer proxy for true free cash flow.
FFO is also a key input in NAV (Net Asset Value) analysis, where analysts capitalize FFO at market rates to estimate the intrinsic value of a REIT's portfolio. When evaluating a REIT's income yield, it's worth comparing how REIT dividends stack up against FFO per share to gauge distribution health.
Real-World Example
Marcus is evaluating two apartment REITs with similar dividend yields. REIT A reports net income of $1.20 per share; REIT B reports $0.80. At first glance, REIT A looks more profitable.
But Marcus checks the FFO figures. REIT A has high depreciation charges on older properties and recently sold a building at a large gain, boosting net income significantly. After the FFO adjustment—adding back $1.40 in depreciation and subtracting $0.90 in gains—REIT A's FFO per share drops to $1.70. REIT B, which owns newer properties with lower depreciation and no asset sales, adjusts to $1.85 per share.
The FFO picture flips the comparison. REIT B generates more recurring operating cash per share despite the lower net income headline. Marcus also checks that REIT B's dividend is $1.40 per share—a 76% FFO payout ratio—well within sustainable territory. He now has a much clearer basis for his investment decision.
Investors exploring similar income-oriented strategies sometimes look at instruments like real estate notes or properties in a qualified opportunity zone as complements to REIT holdings.
Pros & Cons
- Removes the distorting effect of non-cash depreciation, giving a more accurate view of operating performance
- Standardized by NAREIT, making it consistent and comparable across all publicly traded REITs
- Readily available in quarterly and annual REIT earnings reports
- FFO payout ratio provides a reliable signal for dividend sustainability
- Widely accepted by analysts, institutional investors, and rating agencies
- Does not account for recurring capital expenditures needed to maintain properties, which AFFO addresses
- NAREIT's definition allows some variation in how individual REITs calculate FFO, reducing strict comparability
- Excludes interest expense effects that can significantly impact financial health
- Not a GAAP metric, so it isn't audited to the same standard as net income
- Can be manipulated by timing of depreciation elections or property dispositions
Watch Out
FFO is not free cash flow. A REIT with strong FFO can still face cash shortfalls if it needs heavy capital spending to keep aging buildings competitive. Always check AFFO—or at minimum, review the capital expenditure line—before assuming FFO translates directly into distributable cash.
Also watch for "Core FFO" or "Adjusted FFO" figures that REITs sometimes report alongside standard FFO. These may exclude additional items the management team deems non-recurring, but the methodology varies by company and isn't standardized. When comparing REITs, stick to NAREIT-defined FFO for apples-to-apples analysis.
Finally, a high FFO growth rate means little if it's driven entirely by acquisitions funded with debt. Check the balance sheet alongside FFO trends.
The Takeaway
FFO is the foundational performance metric for REIT investors. It cuts through GAAP accounting noise to show what a REIT actually earns from running its properties quarter after quarter. Use FFO per share to compare REITs, the FFO payout ratio to assess dividend safety, and AFFO when you want an even tighter measure of free cash flow. Any serious REIT analysis starts here.
