Price/AFFO: The Distributable Cash Multiple for REITs

Key Takeaways

• Price/AFFO equals share price divided by AFFO per share, the cleanest REIT cash multiple.
• AFFO subtracts recurring capex and straight-line rent from FFO, addressing FFO's main weaknesses.
• Nareit does not standardize AFFO; each REIT defines it slightly differently in supplemental disclosures.
• AFFO multiples typically run several turns above FFO multiples and a few turns below P/E.

What It Is

The AFFO multiple REIT measure is calculated as share price divided by adjusted funds from operations per share. AFFO begins with Nareit FFO and then deducts the recurring real estate spending needed to keep properties leased and competitive. Nareit explicitly notes that there is no industry-standard AFFO definition, so each firm discloses its own calculation in its supplemental reporting.

The result is the closest publicly reported equivalent of free cash flow to equity for a REIT. AFFO supports the dividend, supports any meaningful free cash flow yield discussion, and is the multiple most often quoted in institutional REIT research.

The Intuition

FFO fixes the depreciation problem in GAAP earnings, but it ignores two real cash costs. First, REITs spend on tenant improvement allowances, leasing commissions, and recurring capex such as roof replacements, HVAC, and parking lots, none of which are growth investments. Second, GAAP requires straight-line rent recognition, which records cash you have not yet received, inflating both revenue and FFO.

AFFO strips both out. What is left is a figure that, if held constant, the REIT could distribute year after year without underinvesting in its asset base. That is exactly the figure a dividend-focused investor wants to multiple-up against a share price.

How It Works

The Nareit-style AFFO formula is:

AFFO = FFO
     - Recurring Maintenance Capex
     - Leasing Commissions and Tenant Improvement Allowances
     - Straight-Line Rent Adjustment
     +/- Other Recurring Non-Cash Items

The multiple is:

Price/AFFO = Share Price / AFFO per Share

Recurring capex is the biggest swing item. Property-heavy REITs such as office and retail typically run recurring capex at 15 to 25 percent of NOI, while triple-net retail or self-storage REITs can run below 10 percent because tenants cover most upkeep. CFA Institute curriculum on REIT valuation emphasizes this property-type variation when interpreting AFFO multiples across the sector.

A second common adjustment is stock-based compensation. The Nareit white paper and most SEC supplemental filings include SBC as a real expense in AFFO, which differs from how some technology companies present FCF. The result is that AFFO is harder to flatter than tech-style "free cash flow" disclosures.

Worked Example

A net-lease retail REIT reports:

• FFO per share = $4.00
• Recurring maintenance capex per share = $0.30
• Leasing commissions and tenant improvements per share = $0.20
• Straight-line rent per share = $0.10 (cash collected later)
• Share price = $60

Compute AFFO and the multiple:

• AFFO per share = 4.00 - 0.30 - 0.20 - 0.10 = $3.40
• Price/AFFO = 60 / 3.40 = 17.6 times
• Price/FFO = 60 / 4.00 = 15.0 times

Now compare to an industrial REIT with FFO per share of $3.00, recurring capex of $0.10, leasing of $0.05, and straight-line rent of $0.05, trading at $50:

• Industrial AFFO per share = 3.00 - 0.10 - 0.05 - 0.05 = $2.80
• Industrial Price/AFFO = 50 / 2.80 = 17.9 times
• Industrial Price/FFO = 50 / 3.00 = 16.7 times

The two REITs trade at almost identical Price/AFFO multiples even though the net-lease REIT looked cheaper on FFO. AFFO neutralizes the leasing intensity difference and produces a fairer cash-yield comparison.

Common Mistakes

1. Treating AFFO as standardized. Each REIT defines AFFO its own way. Use the firm's own definition or a research-house standardized version, and stick to one approach across peers.
2. Ignoring property type. Triple-net and self-storage portfolios carry much lower recurring capex than office or industrial. AFFO multiples that look identical can hide very different reinvestment needs.
3. Using EBITDA-based comparisons. REIT EBITDA does not adjust for maintenance capex or straight-line rent either. Pair EBITDA multiples with AFFO multiples, not with each other.
4. Forgetting payout ratios. AFFO payout ratios above 100 percent are unsustainable. Always check the AFFO payout ratio when AFFO multiples look unusually low.
5. Confusing AFFO with FAD or CAD. Funds available for distribution and cash available for distribution are firm-specific variants. They are close to AFFO but not identical, and the labels matter when reading disclosures.

Frequently Asked Questions

What is the AFFO multiple REIT analysts use in simple terms? It is the share price of a REIT divided by its adjusted funds from operations per share. AFFO is FFO minus recurring capex and straight-line rent, so the multiple compares price to cash a REIT could realistically distribute.

How does the AFFO multiple REIT measure affect investment decisions? Income-focused investors rank REITs by AFFO yield (1 divided by Price/AFFO) and check the AFFO payout ratio. A high AFFO yield with a payout ratio comfortably below 100 percent signals supportable dividends with room for growth.

What is a real-world example of the AFFO multiple REIT measure? US net-lease retail REITs have historically traded at Price/AFFO multiples in the high teens to low twenties, while office REITs have traded in the low double digits during periods of leasing stress.

How can investors use the AFFO multiple REIT effectively? Read each REIT's supplemental disclosures to understand its specific AFFO definition, prefer a multi-year average for recurring capex, and pair the multiple with same-property NOI growth and AFFO payout ratio.

How is the AFFO multiple REIT measure different from Price/FFO? FFO adds back real estate depreciation but ignores recurring capex and straight-line rent. AFFO deducts both. Price/AFFO is therefore usually higher than Price/FFO and more closely matches a free cash flow multiple.
