Budgets are an invaluable decision-making tool when tackling challenging business conditions. Static operating budgets are often the standard template for business budgets, but this type of financial modeling can fail to keep pace with changes in your business’s finances, leading to incorrect and misguided financial planning

As an alternative to static budgeting, consider a rolling budget to manage and plan your business’s finances. A rolling budget can bring flexibility and long-term planning to your business by enabling you to measure the actual performance of your business on a regular basis as well as on an annual basis. Let’s take a look at some other aspects and benefits of a rolling budget. 

Here’s what you’ll learn in this guide: :

What is a rolling budget?

Rolling or continuous budgets, also called rolling forecasts, are a dynamic budgeting model that involves adding another period to the end of the budget to replace the previous elapsed period. Once the current accounting period ends, companies create the budget for an incremental term in the future (usually a month or quarter). Because of this, the budget period remains the same.

For example, once the current month (June 2022) ends, your accounting team will create the rolling budget for the period one year in the future (June 2023). In this case, the budget's term is 12 months. Once the current monthly budget ends, an additional new monthly budget is added at the end of the term, maintaining the 12-month or full year’s outlook.

You can create three-month, six-month, and annual rolling budget plans depending on how quickly your financial picture changes. A more flexible budget enables your planning process to cater to long and short-term expenditures.

What are the benefits of a rolling budget?

Here are the advantages of using the rolling budget model:

  • More flexibility: Your budget uses recent financial insights to create realistic spending limits and financial modeling for the next year.
  • More agility: You can expand your budget in line with revenue growth. By having an up-to-date income statement and reports on expenditures, you can take advantage of new opportunities.
  • Better capital allocation: Your CFO can predict cash flow with greater accuracy and inform you of capital allocation choices with better precision.
  • Reduced uncertainty: Thanks to greater agility and flexibility, you can rest assured your financial planning is reacting to market conditions appropriately. With a rolling budget, you can check in on your business’s finances on a regular basis to stay on track.

What are the disadvantages of a rolling budget?

On the other hand, rolling budgets do have a few disadvantages to be aware of, including:

  • Increased resource strain: Every department must shoulder the burden at the end of the month to provide numbers and assist in projections. This strain can lead to a loss of motivation amongst employees and stakeholders. Automation can help relieve this strain and reduce resource expenditure dramatically.
  • Time consuming: The more stakeholders you have, the longer it will take to prepare a budget. 
  • Cultural changes: Companies accustomed to fixed financial planning might find this change too big a hurdle to jump.
  • Increased costs: You must use tools to implement rolling budgets. These tools require additional investment.

Comparing rolling budgets to other methods

How do rolling budgets compare to other types of budgets? Let's take a look.

Rolling versus static budgeting

Static or traditional budgets fix expenses for an accounting period in advance. For instance, if a company earns higher than expected revenues in a quarter, its annual static budget does not change to reflect its increased cash reserves.

In these situations, taking advantage of potentially lucrative capital reinvestment opportunities is challenging. Rolling budgets remove this barrier since the company routinely updates forecasts per business performance.

Static budgeting requires a one-time, significant effort from your company. Most companies dedicate the fourth quarter of a fiscal year to creating their annual budget. In contrast, a rolling budget demands constant attention.

Given the one-time nature of static budgeting, you can execute it manually. However, rolling budgets need software that can automate data collection and reporting.

Rolling versus zero-based budgeting

Here's how zero-based budgeting (ZBB) works:

  • Create a budget from scratch without taking previous financial periods into account. 
  • A manager will consider upcoming expenses based on their department's needs. If they wish to allocate more funds to product development instead of sales, they're free to do so.

Rolling budgets help you account for unexpected costs, something ZBB struggles to handle. ZBB also places outsized importance on a manager's ability to predict trends and profits.

For instance, a manager setting a ZBB budget can predict expenses a month or quarter more accurately than a year in advance. Thus, ZBB is often constrained to shorter terms.

However, ZBB can reorient your focus on profits and uncover hidden inefficiencies. You can quickly eliminate overspending in less than profitable areas thanks to the quick reset that ZBB offers.

Rolling versus incremental budgets

Incremental budgets incorporate some aspects of rolling budgeting. 

  • Accounting teams will add or subtract a percentage from the previous period's budget to derive projections for current periods.
  • For example, if your company spent $500,000 on social media advertising last year, you could increase that amount by 10 percent, giving you a budget limit of $550,000. 

However, this method is inflexible compared to rolling budgets.

Rolling forecasts help you account for business changes faster than incremental methods. Ultimately, incremental methods bring some flexibility to static budgets but do little else.

Rolling versus activity-based budgets

Activity-based budgeting (ABB) is a technique rather than a budgeting model.

  • Managers determine the activities that lead to profits and reduce their associated costs as much as possible.
  • For example, if your company relies on PPC ads to drive sales, optimizing PPC ads by trimming budgets will boost your net margins significantly.

You can implement ABB within your rolling forecasts. For example, you can trim costs within every profit-driving process at the end of the month to preserve your rolling 12-month forecast.

ABB can minimize the importance of cost-centers in your business. For instance, human resources and accounts payable are cost-centers essential to your business. 

Quantifying these departments' impact on profits is tough, making it challenging for you to implement ABB when defining their budgets.

When should you use a rolling budget?

Here are a few guidelines that will help you decide if rolling budgets are the best budgeting method for you:

  • Operating in a dynamic market: Is your sector changing rapidly? Rolling budgets bring much-needed agility and flexibility.
  • The current budgeting process stifles growth: If you routinely view your static budget as a hurdle to growth, it might be time to switch to a rolling method.
  • Lack of connection between budget and sales: Are your expense limits out of sync with sales trends? Rolling budgets can help you align your expense ratio with your profit margin.
  • Constantly missing forecasts: Do you routinely exceed budget limits due to unrealistic forecasts? Rolling budgets can increase flexibility and align limits to a business’ reality.
  • Lack of connection between goals and budget: Are you spending money in the wrong areas? Rolling budgets combined with ABB can help you align goals to budgets.
  • Budgeting ROI is low: If you're spending significant resources on budgeting but cannot see the purpose, switching to a rolling budget might be the right move.

How to implement a rolling budget

Here is a simple process to help you adopt rolling budgets.

Understand resource needs

Mapping resource needs before adopting rolling budgets will help your team adjust to new standards fast. For instance, department heads must prepare numbers and projections in advance since those roles will play a role in budget creation.

You must also test new software that will help you automate and implement rolling budgets. Check whether these increased costs will deliver the ROI you need.

Create monthly budgeting workflows

Define budgeting workflows, along with designating all relevant stakeholders. Your employees will have to collaborate to produce an accurate budget, so run plenty of test scenarios before implementing rolling budgets.

Check with stakeholders to make sure these processes are in line with business goals and expectations.

Adjust budgets for the incremental period

Adjust your budget according to the changes revealed in your budget variance analysis at month end. You might find it challenging to connect every business trend to your budget. For instance, if the cost of raw materials increased by five percent, what does this mean for your operating expenses?

Change what makes sense and move forward. Over time, you'll figure out how different elements relate.


Monitor your business results after adopting a rolling budget. If you're not earning higher margins, or achieving your goals, consider moving back to your previous budget method. 

Conduct a thorough audit of your budget processes to make sure you're giving rolling budgets the best shot to improve your business.

Best practices when using a rolling budget

Here are a few best practices to guide you when implementing a rolling budget:

  • Always determine resource needs before implementing a rolling budget.
  • Use budgeting software to automate and gather financial data during the month-end. You'll save time and reduce employee burden. Spreadsheets will slow you down.
  • Automate your reporting with dynamic, real-time data to offer immediate insights. Excel-based processes will struggle to keep pace with rolling budget demands.
  • Review your budget’s connection to business goals.

What is the difference between a rolling budget and a rolling forecast?

Rolling budgets are often called rolling forecasts. Some forecasts might add revenue-related projections, differentiating them from budgets. However, the process of creating both is the same.

When should a rolling budget be used?

Use a rolling budget if you are experiencing the following:

  • You operate in a dynamic market. 
  • Your current budgeting process stifles growth.
  • A lack of connection between budget and sales.
  • You constantly miss forecasts.
  • A lack of connection between goals and budget.
  • Budgeting ROI is low.

Is a rolling budget the same as a flexible budget?

A rolling budget is not the same as a flexible budget. A rolling budget actually has more flexibility because you can make changes to the financial period, whereas with a flexible budget, this feature is limited to the current period.

Is a rolling budget and a continuous budget the same?

Yes, rolling and continuous budgets are the same. Rolling budgets and continuous budgets are created to be able to continuously be updated throughout the fiscal year. This gives you a lot more flexibility and accurate insights into your business’ finances.
