Capital Rationing – Its Assumptions, Advantages and Disadvantages

Capital rationing is a common practice in most of the companies as they have more profitable projects available for investment as compared to the capital available. In theory, there is no place for capital rationing as companies should invest in all the profitable projects. However, a majority of companies follow capital rationing as a way to isolate and pick up the best projects under the existing capital restrictions.

Definition of Capital Rationing

Capital rationing is the process of putting restrictions on the projects that can be undertaken by the company or the capital that can be invested by the company. This aims in choosing only the most profitable investments for the capital investment decision. This can be accomplished by putting restrictive limits on the budget or selecting a higher cost of capital as the hurdle rate for all the projects under consideration. Capital rationing can be either hard or soft.

Assumptions of Capital Rationing

The primary assumption of capital rationing is that there are restrictions on capital expenditures either by way of ‘all internal financing’ or ‘investment budget restrictions’. Firms do not have unlimited funds available to invest in all the projects. It also assumes that capital rationing can come out with an optimal return on investment for the company whether by normal trial and error process or by implementing mathematical techniques like integer, linear or goal programming.

Capital RationingAdvantages of Capital Rationing

Capital rationing is a very prevalent situation in companies. There are few advantages of practicing capital rationing:


The first and an important advantage are that capital rationing introduces a sense of strict budgeting of corporate resources of a company. Whenever there is an injunction of capital in the form of more borrowings or stock issuance capital, the resources are properly handled and invested in profitable projects. 

No Wastage

Capital rationing prevents wastage of resources by not investing in each and every new project available for investment.

Fewer Projects

Capital rationing ensures that less number of projects are selected by imposing capital restrictions. This helps in keeping the number of active projects to a minimum and thus manage them well.

Higher Returns

Through capital rationing, companies invest only in projects where the expected return is high, thus eliminating projects with lower returns on capital.

More Stability

As the company is not investing in every project, the finances are not over-extended. This helps in having adequate finances for tough times and ensures more stability and increase in the stock price of the company.

Disadvantages of Capital Rationing

Capital rationing comes with its own set of disadvantages as well. Let us describe the problems that rationing can lead to:

Efficient Capital Markets

Under efficient capital markets theory, all the projects that add to company’s value and increase shareholders’ wealth should be invested in. However, by following capital rationing and investing in only certain projects, this theory is violated.

The cost of Capital

In addition to limits on budget, capital rationing also places selective criteria on the cost of capital of shortlisted projects. However, in order to follow this restriction, a firm has to be very accurate in calculating the cost of capital. Any miscalculation could result in selecting a less profitable project.

Un-Maximising Value

Capital rationing does not allow for maximising the maximum value creation as all profitable projects are not accepted and thus, the NPV is not maximized.

Small Projects

Capital rationing may lead to the selection of small projects rather than larger scale investments.

Intermediate Cash Flows

Capital rationing does not add intermediate cash flows from a project while evaluating the projects. It bases its decision only the final returns from the project. Intermediate cash flows should be considered in keeping the time value of money in mind.

Though capital rationing has few disadvantages, it is still followed widely in selecting investment projects. A company should decide on following capital rationing after studying the implications in details.
