Capital budgeting is the process of identifying, analyzing, and selecting long-term investment projects. The capital budgeting process involves generating proposals aligned with strategic objectives, evaluating incremental cash flows, and selecting projects using techniques like net present value. Cash flows must be estimated after-tax and incremental for the initial investment, each period, and the terminal year. Depreciation is a non-cash expense that lowers taxes and must be considered along with capital gains/losses when assets are sold.
