Internal Rate of Return (IRR)
A metric for assessing profitability over time. IRR is the discount rate at which the net present value (NPV) of all future cash flows (positive and negative) from an investment equals zero — including both periodic cash flow (such as rent) and a projected sale at the end of the holding period. It represents the expected annualized return, accounting for income, expenses, and the recovery of capital through a future sale.
