What Are the Types of Budgeting Models? (Explained)

Companies use financial forecasting to create budgets and understand their revenue streams. This process helps create an expectation for companies to use as a reference in the future. On top of that, it also allows companies to control actual performance against the set benchmark. For companies, these tools are crucial in helping save costs and increase profits. In the absence of these budgets, companies cannot function efficiently.

Companies can prepare various types of budgets for the different operation areas. Usually, these budgets fall under operating budgets. Combined with other forecasts, these budgets constitute a company’s master budget.

Therefore, all of these contribute to the final figures that become a part of that budget. Each component is crucial in providing an accurate and reliable budget for actual use.

Companies use budgeting models to help in the preparation of their budgets. These models differ from one company to another based on historical usage. On top of that, each type may have its advantages and drawbacks.

Usually, companies can choose from different types of budgeting models for planning purposes. Before discussing those types, it is crucial to understand what budgeting models are.

What is a Budgeting Model?

A budgeting model is a tool that companies use to prepare their budgets. These models fall under the budget modeling process. Under this process, companies constitute budgets to align their current performance and financial goals. Usually, it involves estimating or predicting the performance in various areas. For example, companies may prepare sales, expenses, cash flow, asset, equity, and liability budgets.

Budgeting models help provide a base for companies to use when preparing budgets. Based on those models, companies can follow steps to create realistic budgets. Once companies use a budgeting model, they continue with it for a long time. Unless the budgeting model provides an unsatisfactory result, companies do not change it. However, each type of budgeting model may result in a different budget.

The choice of budgeting models depends on several factors. Usually, companies must evaluate their needs and assess the model that suits them. Furthermore, the historical usage of these models also plays a crucial role in which one a company will use. Sometimes, companies may alternate between different types of budget models. This way, they can identify any shortcomings and eliminate those during the process.

Static budget

A static budget remains fixed throughout the budget period. Irrespective of the activity level, this budget does not change.

Flexible budget

A flexible budget is the opposite of a static budget. It allows companies to adjust their existing budget for operations.

Incremental budget

An incremental budget takes an existing budget and adjusts it for various factors. Usually, these factors include inflation or changes in activity levels. Companies must use many assumptions for these factors. These budgets are easier to prepare and use by many companies. However, some experts may consider them a conservative approach to budgeting.


Incremental budgets can have various advantages, some of which are below.

Zero-based budget

When companies start budgeting initially, they use a zero-based budgeting model. This model starts from scratch and allows companies to estimate everything from zero. With these budgets, companies can prepare expectations from the ground up.

A zero-based budget can have many advantages, including the following.

Rolling budget

A rolling budget requires companies to update continuously to add a new budget period. This budgeting model involves the same principle as incremental budgeting. However, it is an extension of the existing budget. It rolls the budget over for a shorter amount of time rather than doing so annually. Most companies use the rolling budgeting model since it is more consistent.


Rolling budgets can have the following advantages.

  • It helps companies assess their strength and weaknesses.


Rolling budgets may involve the following disadvantages.
