Investment Decision Analysis (Capital Budgeting) is the process firms use to evaluate, rank, and select long-term capital expenditure projects that require major cash outflows.

Core Mechanics

• Net Present Value (NPV) Supremacy: The gold standard decision tool. If a project’s NPV is greater than zero, it is expected to create firm value and should be accepted.
• Internal Rate of Return (IRR): The specific discount rate that drives a project’s NPV to exactly zero. A project is accepted if its IRR exceeds the firm’s minimum required hurdle rate.
• Payback Metrics: Simple calculations determining how many years are needed to recover the initial cash investment. It is useful for liquidity screening but fails to account for the time value of money or cash flows generated late in a project’s life.
