Capital budgeting is the process of evaluating large investments and expenses to obtain the best returns. The objectives are to select profitable projects, control capital expenditures, and find the right funding sources. The process involves identifying opportunities, evaluating proposals, choosing profitable investments, allocating capital, and reviewing performance. Common techniques used are payback period, net present value, accounting rate of return, internal rate of return, and profitability index. Making the right capital budgeting decisions is important for a business's success as wrong choices can negatively impact funds and long-term projects.
