A rolling or continuous budget is a type of financial planning that involves continually updating a company's budget on a regular basis rather than creating a single budget that covers a fixed time period. This perpetual budget approach allows a company to be more flexible and responsive to changes in the business environment as it allows the budget to be adjusted as needed to reflect actual performance and new opportunities or challenges. Due to this flexible and vibrant nature a company can rearrange and make the necessary modifications to its financial data and express its recent appearance more accurately.

It can also be referred to as a rolling forecast because this ability of flexible estimation stems from its capability to predict future financial data with the aid of historical data. Also, since it works with continuous updates, it can show a better understanding of the current situation of both the business operations and the economic environment in which it takes place.

‍

A rolling budget or a rolling forecast simply works by erasing the recent period which you have just passed while adding a new one at the end of the forecasted budget. This cycle can also be defined as an add-drop period. When an accounting period ends, a continuous budget drops that one and adds a new one regularly at the end of the budget as a foreseeing.

For instance, in order to give a rolling budget example, think of a company whose accounting period ends at the end of the year, and uses quarters as periods. At the beginning of the year, the firm will have a budget plan which covers four quarters of the year. When the first quarter ends, the company removes that period from the budget plan but adds a new one that takes place at the end of the accounting period, in other words, while dropping the first quarter of that year, adds the first quarter of the next year to the budget planning. Hence, the budget can still be completed by covering an entire accounting period. Therefore, the budget can have a continuous structure and also achieves to have a forecast.

The mechanism of creating a rolling budget involves several vital steps, the lack of which can reduce the benefits of this forecasting approach and may adversely affect the efficiency of the decision-making process. The steps on how to prepare a rolling budget are as follows:

1. Establish the Scope of the Plan: Firstly, a valid definition of both the scope and the horizon of the budget plan must be determined. In this step, the objectives and the time should be established clearly. The main target of this rolling forecast should be carefully chosen because this target will be the starting point of the finalized rolling forecast. Moreover, this target and the base plan of the budget can prevent the plan from early failures due to the wrong goal settings from the beginning by covering financial objectives, proper assumptions, and the established time horizon. This time horizon, in other words, the appropriate accounting period, should be decided based on the organization's financial requirements; thus, it can be indicated as a year, two years, or maybe longer than that. In this part, you may also recognize that the degree of detail will decrease as the time frame of the horizon increases.

2. Monitor and Control the Efficiency of the Budget Plan: Once the scope is established, the period of constant monitoring of actual results in comparison to the budget should begin. The essential contributors and specific details of the baseline budget can be identified to reach the basic target which is defined in the previous step. While regularly analyzing financial statements, spotting discrepancies, and examining the causes of variances between real and projected results, having a dispassionate, objective perception and being critical are crucial to fully benefit from an effective rolling budget plan. Furthermore, deciding which metrics should be used and which factors of that measures should be included is a paramount point of this step.

3. Set up the Rolling Budget: As you compose the rolling forecast, it is important to consider your findings from the previous step. As a result, the continuous budgeting plan should depend on the data which reflects the actual performance and business environment modifications. Also, the variables and different contributors should be considered by making various assumptions and modeling these assumptions to unique scenarios. New trends in the market or whether there is an availability to access new information should be closely followed to keep the forecast up-to-date and to avoid the possibility of information asymmetry. In such cases, backup plans and being prepared for compelling situations with the aid of alternative actions can be very helpful for the correct estimation of both the outcomes and financial circumstances of your business. In this step, checking the input data’s source and validity several times is a must in order to prevent the possibility of creating a misleading rolling forecast.

4. Renew the Previous Steps Routinely: Finally, after the first three steps, your rolling budget is ready. However, success and actual results cannot be reached without systematic repetitions of the process. Therefore, the final step gains a different importance since it aims to develop and remedy the budget plan. By measuring actual performance, comparing them with past data, and making the necessary arrangement regularly, a rolling forecast can be kept updated and continuous as its name suggests.

As a result of their characteristics, rolling budgets are used to predict the future whereas a fixed budget plan can only evaluate the past. Therefore, despite the traditional usage of the fixed budget approach, rolling budgets are rapidly becoming a priority among businesses. For a further assessment of these two budget planning preferences, a detailed evaluation of their differences in their nature can be stated as follows:

1. Horizon: A rolling budget can enable a company to have a flexible and revised budget that covers long time periods thanks to its continuous structure; on the other hand, a static budget can only cover a strict accounting period which usually equals a fiscal year (one-year).

2. Updates: As it is briefly mentioned in the previous point, rolling forecasts help to adapt to reversals in the marketplace easily and quickly, with recent updates, and effectively cope with unexpected changes in revenues and costs. However, a fixed budget cannot be observed as capable as a rolling one due to its lack of flexibility.

3. Elasticity and comparability: In addition to its flexibility, a rolling budget is more forward-thinking, focusing on altering future plans in response to actual performance and changes in the business environment. Although a fixed budget is also concerned with differences and variety between real performance and fixed budget volume, it may not be able to produce such an elastic form as a perpetual budget. Depending on the company’s needs, choosing a rolling or stable budget approach can vary.

4. Forecasting precision: Since its proficiency in complying with business and economic environments is visibly higher than fixed budgets, continuous budgets’ forecasting accuracy is also high accordingly.

5. Specification: For a short time period, a fixed budget typically gives a high level of detail, but a rolling forecast may not provide related specifications since it targets a longer accounting period, and it has been observed that the longer the horizon, the lower the level of detail. Moreover, even such details could rapidly alter depending on actual performance and modifications to the business environment

One key benefit of a rolling budget is that it helps a company stay up-to-date with its financial situation. By continually updating the budget, a company can get a more accurate picture of its current financial position and make any necessary adjustments in a timely manner. This can be especially useful for companies that operate in rapidly changing or highly competitive markets, as it allows them to quickly respond to shifts in demand or market conditions. Due to this accuracy, flexibility, and improvements, continuous budgets can be beneficial in the decision-making process of financial managers by adding more value and reality to the mechanism. In addition, organizations can actively manage risks and avert future financial deficits by changing the budget on a regular basis based on the comparison between estimated and planned performance and shifts in the business environment.

‍Another advantage of a rolling forecast is that it allows a company to be more proactive in its financial planning. Rather than waiting for a fixed budget period to end the correction process before making changes, a company can continuously company’s monitor its performance and make adjustments as needed. Therefore, random speculations can be avoided, and the budget becomes more controllable. This can help to ensure that the company is always aligned with its financial goals and can take advantage of new opportunities as they arise.

The third benefit of a rolling budget stems from its requirement for routine data checks. Because reviewing your financial statements again and again, and the regular c of your budget has a significant impact on the performance of the rolling budget, having a broad perspective and developed understanding of the budget occurs unconsciously for the ones who create the plan. Thus, the possibility of losing control over the budget decreases and your proficiency in your financial planning expands. Moreover, having an automated and scheduled analysis period of your budget encourages a culture of financial responsibility and accountability and assists in identifying areas of the company that may require additional support or resources.

Taking everything into consideration, rolling budget plans promote cooperation and communication within the company since it necessitates frequent and continuous revisions which are combined with various perceptions of different departments and individuals. Consequently, this situation ensures that everyone is on the same page regarding their financial priorities and aspirations.

One potential disadvantage of a rolling forecast is that it can be more time-consuming and resource-intensive to maintain. Because the budget is continually being updated, it requires more frequent monitoring and analysis, which can be labor-intensive. Accordingly, the financial resources and staff of an organization may be put under pressure because of not having the tools or knowledge necessary to adequately manage rolling budgets. Furthermore, as it makes sure that everyone who participated in the budget plan process has similar financial objectives and aspirations, it becomes difficult to establish higher levels of organization-wide cooperation and communication.

The possibility of budget creep is another drawback of continuous budgets. They are frequently updated, so there is a chance that budget owners will ask for more money or resources which may cause possible budget overruns or creeps. In order to deal with such an overrun and reduce the risk, a company can manage budget demands by having clear procedures and safeguards in place.

Despite these challenges, a rolling budget can be an effective tool for companies that want to stay agile and responsive to changes in the business environment. By continually monitoring and adjusting their financial plans, companies can stay on track to achieve their financial goals and stay competitive in an increasingly dynamic market. Overall, a rolling budget is a flexible and proactive approach to financial planning that can help companies to achieve long-term success.

Certain companies might not be suitable to use rolling budgets, especially the ones that operate in a stable and predictable financial environment and have a strong background and history in the market it operates. They may benefit from a fixed budget more effectively than a rolling one and may cut their budget planning costs. However, these continuous forecasts can be very appropriate for businesses that take place in dynamic and rapidly evolving environments – such as a startup environment.

In contrast to its add-drop approach, a rolling forecast still contains a full accounting period but does not require to begin forming a budget from scratch. Therefore, a start-up will not have to search for excess funds and investments to create a fixed budget but can arrange a rolling budget depending on the availability of existing resources and their own financial needs. As it is important for startups to set limitations on both their budget and cash flow statements, such a budget plan can allow startups to create effective control mechanisms.

As it is mentioned before, the capacity to increase financial forecasting accuracy is one of the prior advantages of rolling forecasts which is a key benefit for startups. Due to the characteristics of a typical startup operations market that is hurried and changing quickly, it can be challenging to correctly forecast future financial success for them. By evaluating their financial input data repeatedly and updating budget plans regularly to catch up with the business and market alterations, startups can have a more informed decision-making process about resource allocation and capital investments. Also, this routine monitoring creates a truthful and realistic perspective for the startup and prevents the formation of a corrupted culture from the beginning. As a result, startups can stay away from financial shortfalls with the aid of rolling budgets.

Although it can be hard to effectively evaluate and initiate a budget plan which looks forward from such an early stage, and the tools and expertise of a rolling budget may be costly for a startup, in order to efficiently manage their financial resources and prepare for future growth, a rolling forecast can still be a useful suggestion.

To conclude, regardless of their minor inefficiencies, rolling budgets are on their way to becoming a budget plan that can take a leading position in the market by making a striking impression against fixed, traditional budget plans with their vital benefits, an active structure that includes adding and dropping the parts of an accounting period, and their successful usage in a startup environment.
