What is AFFO?

Adjusted Funds From Operations (AFFO) is a metric used to evaluate Real Estate Investment Trusts (REITs). It refines Funds From Operations (FFO) by subtracting recurring capital expenditures needed to maintain properties, along with straight-line rent adjustments and leasing costs, to give a clearer picture of sustainable cash flow available for distribution.

The formula

AFFO = FFO − Recurring Capital Expenditures − Straight-Line Rent Adjustments − Leasing Commissions/Costs. Dividing AFFO by shares outstanding gives AFFO per share, often used to assess dividend sustainability.

This calculator is for general financial education. Actual REIT reporting practices for AFFO vary by company since it is a non-GAAP measure.
