Limitations of Capital Budgeting
Companies looking to expand or introduce new product lines use capital budgeting as a way to determine potential profits and losses associated with particular projects. When deciding between different project options, companies must determine which option will provide the best return on investment. As the value of money may change with time, capital budgeting methods have certain limitations in terms of anticipating the effects of future economic conditions.

Capital Budgeting
-
Capital budgeting centers around capital expenditures, which involve large outlays of money to finance potential projects. These types of projects --- such as building expansions, advertising campaigns or research and development plans --- typically last for more than a year and involve a range of different variables within the planning process. As the number of variables increases, the risk of miscalculations and lost revenues increases accordingly. In effect, capital budgeting limitations become more pronounced as the number of projects under consideration increases. Maximizing return on investment requires companies to calculate current net profits and losses based on future projections that may or may not play out.
Budgeting Methods
-
Companies may choose between different methods of capital budgeting based on the types of criteria used to determine projected profits and costs. Capital budgeting methods vary according to the type of criteria a company uses to gauge profits and losses. One method, known as the payback period, bases project selections on the length of time it takes a company to recover its initial investment. Another method, known as the internal rate of return, bases project selections on the actual rate of return investors can expect to receive. The net present value method calculates a project's current value based on the net result from anticipated profits and losses.
With each method, companies must consider the cost outlay, time investment and profit earnings based on the time investment for each individual project. As types of projects require different types of resources --- such as equipment and supplies for new product lines versus manpower for advertising campaigns --- companies must determine which budget method will provide the most effective or accurate calculations when selecting among different projects.

Discounted Cash Flows
-
As economic markets change over time, capital budgeting decisions must incorporate the effects of market changes to realize the real value of the projects under consideration. Capital budgeting processes use discounted cash-flow calculations to assess each project's present-day value. To do this, managers must adjust a project's future cash-flow values in present-day cash-value terms. In effect, managers discount future cash values based on anticipated inflation effects and opportunity losses in terms of investing available capital now versus letting the money earn interest on its own. This focus on present-day values may place limitations on a company's ability to choose the most cost-effective project in cases where miscalculations in expected profit or cost margins occur.
Time Value of Money
-
Supply and demand levels within an economic market determine the time value of money as interest rates rise and fall. High interest rates result in value increases, while low interest rates lead to decreases in money value. Capital budgeting calculations can't anticipate the changes that occur within economic markets or the conditions that trigger these changes. As a result, calculations used to determine future profits and costs can only estimate money values within different points in times. In effect, miscalculations in predicted values skew capital expenditure amounts for the projects under consideration. As economic markets consist of different areas or sectors, different types of projects may also encounter varying market conditions over time.
