AFFO Calculator — Adjusted Funds From Operations

Calculating AFFO is a two-step process that starts with standard net income and transitions through Funds From Operations (FFO) before arriving at the final adjusted figure. First, FFO is derived by taking net income, adding back depreciation and amortization (D&A) and any losses on asset sales, while subtracting gains on asset sales and interest income: ffo = net_income + d_and_a + loss - gains - int_inc. Next, AFFO refines FFO by factoring in straight-line rent adjustments, routine maintenance capital expenditures, and recurring capital outlays required to keep properties operational: affo = ffo + rent_inc - capex - rout_maint.

Imagine evaluating a commercial retail REIT over the fiscal quarter. The company reports a net income of $2,000,000. During the period, depreciation and amortization total $800,000, and the firm records a loss on asset sales of $50,000. There are no gains or interest income to subtract, resulting in an initial FFO of $2,850,000 ($2,000,000 + $800,000 + $50,000). To find the AFFO, we adjust for straight-line rent increments of $100,000, subtract $400,000 for routine maintenance, and deduct $300,000 for standard tenant improvements and capital expenditures. Applying the formula, the final AFFO is $2,250,000 ($2,850,000 + $100,000 - $400,000 - $300,000), giving investors a realistic picture of distributable cash flow.

When analyzing REIT performance, always distinguish between routine maintenance capital expenditures and growth-driven capital expenditures, as only the former should reduce AFFO. Furthermore, examine multi-year trends rather than single-quarter figures to smooth out seasonal volatility in maintenance costs. Finally, compare a REIT's AFFO payout ratio alongside its traditional FFO payout ratio to determine if dividend payments are genuinely covered by recurring operational cash flows.
