Understanding FFO and AFFO

Intermediate Guide • 14 min read • Updated January 2026

When analyzing Real Estate Investment Trusts (REITs), traditional metrics like Net Income and P/E ratio often tell an incomplete story. Heavy depreciation charges on physical properties make Net Income less useful for understanding cash generation. This article explains two essential REIT metrics: FFO (Funds From Operations) and AFFO (Adjusted Funds From Operations).

In this comprehensive guide, we'll explore how FFO and AFFO are calculated, why they matter for dividend analysis, how to use them for valuation, their limitations, and the red flags to watch for when analyzing REITs.

1. Why REITs Need Different Metrics

REITs own physical real estate—buildings depreciate for accounting purposes, but the properties often maintain or increase in value. This creates a mismatch between accounting income and economic reality:

Metric What It Measures Problem for REITs
Net Income GAAP profit after all expenses Depressed by large non-cash depreciation
EPS Net income per share Same issue—artificially low
P/E Ratio Price relative to earnings Misleadingly high or meaningless
FFO Cash-like operating performance Adds back depreciation—more useful
AFFO Sustainable cash available Adjusts for maintenance CapEx

The Depreciation Problem: Example

Line Item Amount Notes
Rental Revenue $100 million
Operating Expenses -$40 million
Interest Expense -$15 million
Depreciation -$35 million Non-cash charge
Net Income $10 million Looks weak
Add back: Depreciation +$35 million
FFO $45 million Better reflects cash generation

šŸ’” Why Depreciation Doesn't Tell the Whole Story

Accounting rules require REITs to depreciate buildings over 27.5-39 years. But a well-maintained apartment building doesn't lose 3-4% of its value every year—it often appreciates. FFO removes this accounting distortion to show operating cash flow more clearly.

2. What is FFO (Funds From Operations)?

FFO is a standardized metric developed by Nareit (National Association of Real Estate Investment Trusts) to measure REIT operating performance. It adds back depreciation and removes gains/losses from property sales.

FFO Formula (Nareit Definition)
FFO = Net Income + Depreciation + Amortization āˆ’ Gains on Property Sales
$10M + $35M + $2M āˆ’ $5M = $42M FFO

FFO Components Explained

Component What It Is Why Adjusted
Net Income Starting point (GAAP earnings) Base for calculation
+ Depreciation Non-cash charge for building wear Added back—buildings don't lose value like equipment
+ Amortization Non-cash charge for intangibles Added back—non-cash expense
āˆ’ Gains on Sales Profit from selling properties Removed—one-time, not recurring
+ Losses on Sales Loss from selling properties Added back—one-time event

3. What is AFFO (Adjusted FFO)?

AFFO goes further than FFO by subtracting recurring capital expenditures (maintenance CapEx) needed to keep properties operating. Many analysts consider AFFO a better measure of sustainable, distributable cash flow.

AFFO Formula (Common Approach)
AFFO = FFO āˆ’ Maintenance CapEx āˆ’ Straight-Line Rent Adjustment āˆ’ Leasing Costs
$42M āˆ’ $6M āˆ’ $2M āˆ’ $1M = $33M AFFO

AFFO Adjustments Explained

Adjustment What It Is Why It Matters
Maintenance CapEx Recurring spending to maintain properties (roofs, HVAC, etc.) Real cash outflow required to sustain business
Straight-Line Rent Accounting smoothing of rent over lease term Removes non-cash revenue recognition
Leasing Costs Commissions, tenant improvements Real costs to maintain occupancy
Stock Compensation Non-cash employee compensation Some REITs adjust for this

āš ļø No Standard AFFO Definition

Unlike FFO (which Nareit standardized), AFFO has no official definition. Each REIT calculates it differently. Some call it "CAD" (Cash Available for Distribution) or "FAD" (Funds Available for Distribution). Always check how a specific REIT calculates its AFFO before comparing across companies.

4. FFO vs. AFFO: Key Differences

šŸ“Š FFO (Funds From Operations)

  • Nareit-standardized definition
  • Adds back depreciation
  • Removes property sale gains/losses
  • Does NOT adjust for maintenance CapEx
  • More comparable across REITs
  • May overstate sustainable cash flow

šŸ’µ AFFO (Adjusted FFO)

  • No standardized definition
  • Subtracts maintenance CapEx
  • Adjusts for straight-line rent
  • Better reflects "true" cash available
  • Harder to compare across REITs
  • Closer to sustainable dividend capacity

FFO vs. AFFO Comparison Example

Metric REIT A REIT B Notes
Net Income $50M $50M Same starting point
+ Depreciation $80M $80M Same
āˆ’ Gains on Sales $10M $5M REIT A sold more properties
FFO $120M $125M REIT B looks slightly better
āˆ’ Maintenance CapEx $15M $40M REIT B has older buildings
āˆ’ Straight-Line Rent $3M $2M
AFFO $102M $83M REIT A actually better!

šŸ“Š The Lesson

FFO alone can be misleading. REIT B looked better on FFO, but its high maintenance CapEx (older properties) means less cash is actually available for dividends. AFFO reveals the true picture.

5. Calculating FFO and AFFO

Here's a step-by-step example using hypothetical numbers:

Step-by-Step FFO Calculation

Step Item Amount
1 Start with Net Income $200 million
2 Add: Real Estate Depreciation +$350 million
3 Add: Amortization of Intangibles +$25 million
4 Subtract: Gains on Property Sales -$75 million
FFO $500 million
Shares Outstanding 250 million
FFO per Share $2.00

Step-by-Step AFFO Calculation

Step Item Amount
1 Start with FFO $500 million
2 Subtract: Recurring CapEx -$75 million
3 Subtract: Straight-Line Rent Adjustment -$15 million
4 Subtract: Leasing Commissions -$10 million
AFFO $400 million
Shares Outstanding 250 million
AFFO per Share $1.60

6. Payout Ratios and Dividend Coverage

REITs must distribute at least 90% of taxable income as dividends. Payout ratios help assess dividend sustainability:

Payout Ratio Formulas
FFO Payout Ratio = Annual Dividend Ć· FFO per Share
AFFO Payout Ratio = Annual Dividend Ć· AFFO per Share
$1.50 dividend Ć· $2.00 FFO = 75% FFO payout | $1.50 Ć· $1.60 AFFO = 94% AFFO payout

Payout Ratio Interpretation

AFFO Payout Ratio Interpretation Dividend Safety
< 75% Strong coverage; room for dividend growth Generally safe
75% - 85% Healthy coverage; typical for stable REITs Adequate
85% - 95% High payout; limited cushion Moderate concern
> 95% Very tight; dividend at risk if earnings dip Elevated risk
> 100% Paying more than earning; unsustainable High risk of cut

Payout Ratio Example

REIT AFFO/Share Dividend/Share Payout Ratio Assessment
REIT A $3.50 $2.50 71% Well covered
REIT B $2.00 $1.70 85% Adequate
REIT C $1.20 $1.15 96% Very tight
REIT D $0.80 $1.00 125% Unsustainable—cut likely

āš ļø Payout Ratio Isn't Everything

A low payout ratio doesn't guarantee dividend safety. Other factors matter: debt levels, interest rate exposure, tenant concentration, lease expirations, and management quality. A REIT with 70% payout but heavy debt maturities may be riskier than one with 85% payout and conservative leverage.

7. P/FFO Valuation

P/FFO (Price to FFO) is to REITs what P/E is to regular stocks. It shows how much investors pay for each dollar of FFO:

P/FFO Formula
P/FFO = Stock Price Ć· FFO per Share
$50 stock price Ć· $2.50 FFO = 20x P/FFO

P/FFO by REIT Sector

REIT Sector Typical P/FFO Range Why
Industrial 20-30x Strong growth; e-commerce tailwinds
Data Centers 18-25x AI/cloud growth; high demand
Cell Towers 20-28x Recurring revenue; 5G expansion
Residential (Apartments) 15-22x Stable demand; inflation hedge
Healthcare 12-18x Aging demographics; operator risk
Retail (Strip Centers) 10-15x Grocery-anchored; stable
Office 8-14x Remote work headwinds; uncertainty
Malls 6-12x E-commerce disruption; declining traffic

*Ranges are approximate and vary by market conditions, individual REIT quality, and growth prospects.

8. AFFO by REIT Sector

Different REIT types have different CapEx requirements, affecting the gap between FFO and AFFO:

REIT Sector Typical FFO-to-AFFO Gap Why
Triple-Net (NNN) Small (5-10%) Tenants pay maintenance; minimal landlord CapEx
Cell Towers Small (5-10%) Low maintenance requirements
Industrial Moderate (10-15%) Simple buildings; lower CapEx needs
Self-Storage Moderate (10-15%) Low-maintenance structures
Apartments Moderate (15-20%) Regular unit turnover and updates
Office Large (20-30%) Tenant improvements; leasing costs
Malls Large (25-35%) Heavy CapEx to attract tenants
Hotels Large (25-40%) Constant room renovations needed

šŸ’” Why Triple-Net REITs Are Popular

In triple-net (NNN) leases, tenants pay property taxes, insurance, AND maintenance. This minimizes landlord CapEx, making FFO and AFFO nearly identical. Examples include Realty Income (O), National Retail Properties (NNN), and STORE Capital. The predictable cash flows make dividend analysis more straightforward.

9. Limitations and Red Flags

Limitation Description What to Do
Non-GAAP FFO/AFFO are not standardized (especially AFFO) Read the company's definitions
Backward-Looking Historical metrics don't predict future Consider forward guidance
Manipulation Risk Companies can classify expenses favorably Compare to peers; look at trends
Ignores Debt FFO/AFFO don't show leverage risk Check debt ratios separately
One Metric Isn't Enough Need full picture of REIT health Use multiple metrics together

Red Flags to Watch

Red Flag What It Suggests
AFFO payout ratio > 100% Dividend may not be sustainable
FFO declining year-over-year Operational deterioration
Large gap between FFO and AFFO High maintenance burden; older properties
Company changes AFFO definition frequently May be managing optics rather than operations
FFO/AFFO growing only through acquisitions Organic growth may be lacking
Stock-based compensation excluded from AFFO Real cost being ignored

10. FAQ: Frequently Asked Questions

Why can't I just use P/E ratio for REITs?
P/E ratios are often misleading for REITs because Net Income includes large non-cash depreciation charges. A REIT might show low or even negative EPS while generating substantial cash flow. For example, a REIT with $1.00 EPS and $3.00 FFO would have very different P/E (high) vs. P/FFO (lower) multiples. P/FFO gives a clearer picture of valuation relative to cash-generating ability.
Is FFO or AFFO more important?
Both have value. FFO is standardized and better for comparing across REITs. AFFO better reflects sustainable distributable cash but varies by company definition. For dividend safety analysis, AFFO is generally more useful because it accounts for maintenance CapEx. For peer comparison, FFO may be more reliable. Many analysts look at both.
What's a "good" FFO growth rate?
It depends on the REIT sector. High-growth sectors (industrial, data centers) might show 5-10%+ annual FFO growth. Stable sectors (triple-net retail) might target 3-5%. Anything consistently above 3% generally supports dividend growth. Negative FFO growth is a warning sign unless there's a clear temporary reason (like a large tenant bankruptcy).
Why do some REITs use "Core FFO" or "Normalized FFO"?
Companies often report "Core FFO" or "Normalized FFO" to exclude items they consider one-time or unusual—like acquisition costs, severance, or legal settlements. This can be legitimate (removing true one-time items) or aggressive (excluding recurring "one-time" costs every year). Check what's being excluded and whether it's consistent year-to-year.
Can a REIT with >100% payout ratio be safe?
Temporarily, yes—if it's due to a one-time event or timing issue. But sustained payout ratios above 100% mean the REIT is paying out more than it earns, which requires either selling assets, taking on debt, or cutting the dividend. Some high-yield REITs operate this way for extended periods before eventually cutting. It's a significant warning sign.
How do interest rates affect FFO?
Rising interest rates increase borrowing costs, reducing FFO for REITs with variable-rate debt or upcoming debt maturities. If a REIT has to refinance debt at higher rates, interest expense rises and FFO falls—even if operations are unchanged. Check debt maturity schedules and fixed vs. variable rate mix. Higher rates also make REIT dividends relatively less attractive vs. bonds, potentially pressuring stock prices.
Where can I find FFO and AFFO data?
REITs report FFO in their quarterly and annual earnings releases and SEC filings (10-Q, 10-K). Look in the "Supplemental" or "Financial Highlights" sections. AFFO may be called FAD (Funds Available for Distribution) or CAD (Cash Available for Distribution). Financial sites like Seeking Alpha, REIT.com, and company investor relations pages typically provide these metrics. Always verify the company's specific calculation methodology.

Conclusion

FFO and AFFO are essential tools for analyzing REITs, providing better insight into cash-generating ability than traditional metrics like Net Income or EPS. FFO removes the distortion of depreciation accounting, while AFFO goes further to show cash actually available for dividends after maintenance spending.

Key takeaways:

Understanding these metrics helps you read REIT financials more effectively, but remember: no single metric guarantees investment success. REITs face real risks including interest rate sensitivity, tenant credit issues, and sector disruption. Use FFO and AFFO as part of comprehensive analysis, not as standalone decision tools.
