In this lesson, we will explain the purpose of budget controls and explore several key related concepts including top-down budgeting, bottom-up budgeting, zero-based budgeting and flexible budgeting.

What Is a Budget?

In this lesson, we will explore various types of budget controls used in organizations. In order to understand the various budget controls, let's first define the term 'budget.'

A budget is a financial plan for saving, spending and borrowing money. A budget helps an organization determine whether it can operate based on projected income and expenses for a period of time. A budget is generally prepared for a period of one year but is broken down monthly for various spending and saving purposes. Accurate projection of revenue and expenses is vital for organizational planning for resources like people, materials and money. The purpose of a budget is:

  • To provide a projection of revenues and expenses
  • To forecast an organization's financial future based on the outcomes of organizational plans
  • To measure and compare projected expenses to actual expenses
  • To establish a cost ceiling for operational, or short-term day-to-day expenses, and capital, or long-term expenses for major projects

We now know that a budget is used to project income and expenses for a period of time. But how are budgets used as a management control? Let's visit a few universities to see how budget controls work for them.

Types of Budget Controls

There are several budget controls used in organizations:

  • Top-down budgeting
  • Bottom-up budgeting
  • Zero-based budgeting
  • Flexible budgeting

Top-Down Budgeting

Top-down budgeting starts at the top of an organization and is handed down to lower departments. There are several pros and cons to this type of budget control.

TD University's science department uses top-down budgeting. Top management creates the department's budget based on a combination of forecasting for future revenues and expenses and the previous year's actual budget results and sends the money down the university pipeline.

Top-down budgeting can be a good thing because lower management does not have to take time to prepare the budget. This is a time-saver for lower management, who are more involved in the operational process rather than the overall strategic plan.

However, a budget prepared by those who are not directly involved with the day-to-day operations of a department may not be aware of the particular expenses related to the department. This could be problematic for lower-level managers who may not be able to retain the necessary resources to meet organizational objectives. Once the budget is given to the department, monies can be spent according to what has been allocated. Supplies can be purchased, professors can be paid and student activities can be planned.

Bottom-Up Budgeting

Bottom-up budgeting starts at the bottom of an organization. A budget is decided by lower-level management and then presented to top management for approval. Top management will either approve the proposed budget or send it back down to lower management for review and modification. There are several pros and cons to this type of budget control.

Budget University's art department uses bottom-up budgeting. The dean of the art department decides how much money he needs to run the department. These decisions are based on the same sort of information used in top-down budgeting, like forecasting and the previous year's actual results.

Bottom-up budgeting can be a good thing because lower management plans the budget based on the needs of the specific department. A manager of a department is more familiar with what is required, like supplies, labor and capital, to meet departmental goals.

However, lower management may not have the experience in creating complicated financial documents. Lower management may not be aware of the overall strategic plan of the organization. The budget may not be feasible because of top management plans to allocate resources elsewhere in the organization, like toward capital improvements or a major purchase of equipment.

Rather than the decisions being made by those who are outside of the department, those who are closest to the department make the decisions. Professors and staff in the department provide the dean with a list of their anticipated needs, and he creates a budget around the costs of things like buying clay, brushes and paint. While this method is practical because the dean of the art department knows what he needs to teach aspiring young artists, he is not an expert in accounting. He may not know how to write the document correctly.

Zero-Based Budgeting

Zero-based budgeting starts at a zero balance, and expenses are added as they are deemed necessary and are justified. This type of budget does not rely on a previous year's performance or actual results. Expenses are added on a per-item basis. Each item is analyzed for alternatives that cost less. It is also not compared to a prior year's budget. It does not matter if the new budget exceeds the spending in a prior year as long as the expenses are justified and have been compared for alternatives. There are several pros and cons to this type of budget control.

ZB Public University's culinary department uses zero-based budgeting. The chef instructors review their lesson plans and any special events they may be hosting throughout a period of time. This could be a quarter or a year. Each chef instructor makes a list of things they need for their classrooms and programs. The dean reviews the lists and asks the instructors to look at alternative items that may cost less.

Zero-based budgeting is a good thing because it forces a manager to take a good look at expenses and justify the expenses or look at alternative products and services. It can streamline spending by always looking for new ways to cut costs. However, because zero-based budgeting does not rely on forecasting or past budgets, expenses can fluctuate vastly. Alternatives that existed in the past may not be available in the new period.
