Capital budgeting is the process of evaluating potential major projects or investments. There are traditional and discounted cash flow methods used for capital budgeting. Traditional methods include payback period and accounting rate of return. Discounted cash flow methods include net present value, profitability index, and internal rate of return. Net present value is considered the best method as it takes into account the time value of money by discounting future cash flows. A project is accepted if it has a positive net present value or a profitability index greater than one.
