Rolling Forecasts for Small and Medium Sized Businesses: A Definitive Guide

The purpose of any forecast is to provide the closest possible snapshot of the future for business teams to plan and budget their activities. A good forecast is determined by its flexibility to evolve with changing conditions instead of sticking to the same initial projections across the financial period. As such, rolling forecasts are a solid first step toward agile planning and budgeting for organizations looking to become more reactive and adaptive to change. 

The rolling forecasts approach helps businesses to project future performance more accurately by adjusting ‌forecasts based on ongoing internal or external conditions. However, many companies aren’t taking advantage, with only 19% to 25% using 12-month rolling forecasts in 2021, according to FSN research.

Learn more about what rolling forecasts are, why even small and medium sized businesses need them and why they’re better than traditional budgeting. You’ll also learn about best practices for implementing rolling forecasts in your organization and how a unified xP&A platform can simplify and streamline the process.

What Is a Rolling Forecast?

A rolling forecast is a financial management approach that enables businesses to continuously plan, forecast and reforecast for a predefined period, e.g., for the next 6 or 12 months. It empowers decision-makers and finance professionals to make effective short-term decisions, predict multiple scenarios for the future of the business more accurately and re-allocate resources to ensure the business delivers the forecasted results.

The starting point for rolling forecasts is a baseline forecast for the upcoming fiscal period based on ‌historical data related to critical KPIs. Once done, it’s used to create projections for the next 9 or 12 months ahead so that the business has a consistent snapshot of the future.

Rolling financial forecasts have three important traits:

  • Methodical: They follow a series of steps to develop and implement.
  • Iterative: They’re reevaluated and perfected over multiple instances of those systematic steps.
  • Adjustable: They can be adjusted or revised based on the circumstances.

The beauty of rolling forecasts is that instead of being a fixed point in time, they’re constantly evolving and adding a fresh perspective to the time horizon based on current scenarios.

Why Do Small and Medium Sized Businesses Need a Rolling Forecast?

Rolling forecasts can help financial planning and analysis (FP&A) teams by providing them with a more accurate view of future performance. By using past data to create projections for the coming period, rolling forecasts can help identify trend patterns and possible issues that may impact future results. This allows FP&A teams to plan accordingly and make the necessary adjustments to ensure that they meet their goals. 

Additionally, this approach facilitates driver-based planning, where you can base your forecasts on key metrics, like human capital, sales, market share and production rates, instead of past results.

Perhaps the biggest incentive for using rolling forecasts is the sense of accountability it provides to stakeholders. It helps answer the critical questions, such as whether you underperformed, exceeded expected results or achieved the set targets. Once you evaluate the numbers, you can find the reason behind the outcomes, determine whether to stop, scale or repeat the actions and tweak your plans and budgets accordingly.

In other words, rolling financial forecasts allow you to understand the “why” behind the numbers and help turn insights into real-world actions.

Traditional Budgeting vs. Rolling Forecast

For decades, annual budgets have been how small and medium sized businesses plan ‌preliminary financial and operational targets and allocate resources to various departments accordingly. That’s primarily because teams from across the organization dedicate resources and spend months preparing a highly detailed document that measures actual-vs-forecasted results of the current year and use them as a reference to prepare plans, budgets and projections for the upcoming fiscal year.

But the problem with an annual budget is its static nature because it isn’t updated for the whole 12 months. And in today’s hyper-competitive and constantly fluctuating business landscape, a lot can happen in this amount of time. The entire process is also very labor-intensive and time-consuming and can take up to two to four months to complete. In that duration, the data used to prepare the annual budget will likely become stale when it reaches final review and is stamped “okay” for implementation.

To understand the value rolling forecasts add to the financial planning process, you need to look at the core objectives you want to achieve. Ideally, a business uses forecasting techniques to:

  • Get an accurate picture of the business’s performance in the upcoming quarters or years so that the right decisions can be made
  • Perform an impact analysis of those decisions before they are made
  • Curate alternate plans and budgets based on possible scenarios that are likely to occur under certain predicted conditions


This high level of flexibility and reactivity is what makes rolling forecasts a better approach than a static budget. You no longer have to wait until ‌year’s end to see what went wrong in the first or second quarters, hoping not to repeat those mistakes. Instead, with monthly or quarterly reviews, department leaders can see variances and deduce possible explanations for differences from the original predictions. Then use those analyses as a baseline to adjust in the plans for the upcoming quarters or months.

Rolling Forecast vs. Traditional Forecasts

A rolling forecast is constantly updated as new data becomes available. This means that the forecast changes to reflect the most recent data, rather than using a single point in time to make a prediction.

A normal or traditional forecast is created once but not updated as new data becomes available. It uses a single point in time to make a prediction, which may become inaccurate depending on how conditions or data change after the forecast is finalized.

4 Key Benefits of Rolling Forecasts

Improved Risk Analysis

Due to the high market volatility, the influence of economic and political situations and new government policies, there’s always a risk involved that can impact business performance. With rolling forecasts, you’re continually evaluating the changing conditions and using them to update your action plans and budget allocations, allowing you to stay on track to achieve your goals.

Higher Forecast Accuracy

Organizations factor in many internal and external business variables during the FP&A forecasting process and predict their impact on future performance. For example, an increase in the electricity tariff or a new government policy that impacts the market you operate in will mandate fine-tuning your planned financials and resource allocations to reflect the imminent changes. Rolling forecasts give you the ability to make your plans and budgets more reactive, accurate and reliable to ensure you have accounted for such changes and brace for their impact.

Continuously Monitor Cash Flow

Finance pros can regularly review their company’s cash flow performance with a rolling forecast. It helps analyze cash inflow and outflow patterns and dramatically improves overall cash management, allowing the finance people to optimize its flow across the value chain proactively.

Track Operational and Financial Performance

Rolling forecasts enable businesses to continuously monitor and factor in critical performance drivers, such as production rates, sales, human resources, consumer trends and more. They give you a great reason to revisit the performance numbers and compare your projections to your actuals. You can easily identify any variances and take prompt actions based on what caused the discrepancy and how it’ll affect future decisions. This allows your FP&A team to align resources and costs and build flexible strategic plans to achieve business objectives more efficiently.

Rolling Forecast Best Practices for FP&A Teams

The benefits of implementing rolling forecasts are plenty, but the approach is often underutilized. Some organizations have completely replaced their annual budgeting practice with rolling forecasts, while others are using a hybrid model with both rolling forecasts and the annual budget. That’s mainly because the annual budget acts as a failsafe for organizations that might fail to implement a rolling forecast framework due to its complex, dynamic nature.

Nevertheless, we have laid out a few rolling forecast best practices to help organizations implement its approach and reap its benefits.

Let Go of Excel-Based Processes

Microsoft Excel, though extremely popular in the finance community, is not designed to be a dynamic financial planning and forecasting solution.

Sure, some small and even midsized organizations have their entire financial planning life cycle built on spreadsheets. However, the amount of manual work that goes into preparing and updating reports, along with the high risk of errors and complexity of data manipulation, make it an unsuitable solution.

The result? By the time you complete a baseline forecast, you’re likely to be working with outdated data to work on the series of rolling forecasts and analyses.

Unless you opt for an add-in that extends Excel’s capabilities and provides a centralized server with reporting automation capabilities, your best bet is to go for modern XP&A solutions. They automate the data collection process and bring siloed data from various financial and non-financial sources into a single data model.

From there, it becomes much easier for users to perform scenario and variance analysis, include different business drivers, and understand the impact of modifications in the plan and budget. It also helps create reports and populate dashboards based on multidimensional datasets with ease. These platforms allow comparing actuals with forecasted data and scenario planning without switching between files and applications.

All of this spikes up the productivity of all teams involved in the rolling forecast power BI process and provides more time to identify, report and analyze market conditions to factor in the possibility of acquiring new opportunities and revenue streams. Solutions like Acterys unlock the financial planning capabilities of Power BI, giving users the ability to build, analyze, visualize and adjust rolling financial forecasts with ease and speed.

Specify the Rolling Forecast Time Horizon


At the beginning, it’s essential to work out the timeframe for a rolling forecast and its frequency. The general trend is forecasting for 12 months ahead in time, but in some situations, the rolling forecast time frame is 15, 18 or 24 months. Factors that impact the rolling financial forecast duration include the nature of the business, industry fluctuations, economic stability and business growth rates, among others.

12 Month Rolling Forecast Time Horizon

Next, you need to determine the rollover period or the frequency of the forecasts. Generally, it is the month-to-month rollover period, e.g., on 30th June 2024, you’ll add a new forecast for the month of June 2025 at the end. The same rule applies to quarter-to-quarter and week-to-week (rarely used) rollover periods.

You must ensure that the entire exercise aligns with your business cycle to achieve short and strategic goals.

Determine the Objectives and Value Drivers

Before working on the rolling financial forecast model, it’s critical to determine the goals of your projections, who’ll be using them and for what purpose. With clearly defined objectives, the process becomes streamlined, allowing your team to spend the time and energy creating forecasts with the right focus.

The next step is to pinpoint all the value drivers (both internal and external) that have the most impact on your business performance. Internal drivers may include labor costs, orders, production rates, commodity prices, web traffic and lead conversion rates. External drivers can be supplier availability, government policies, political changes, currency exchange rates and many others.

Identifying key value drivers specific to your business allows business leaders and managers to focus on what’s important. Using the right drivers won’t only save time and make rolling forecasting a doable task but also facilitate evidence-based financial modeling, improve analysis and help develop alternative scenarios more accurately.

Rolling Forecast: Value Drivers That Impact Business Performance

Perform Comparison Among Different Forecast Periods

Determining whether your rolling forecasts are hitting the mark or how far off they are for the intended results. And what better way to do it than performing variance analysis to compare actuals vs. forecasts for multiple periods across the time horizon. This involves comparing rolling forecasts for each period instead of the entire fiscal year. Meaning you must take data from the 1st month to the last month of your rolling forecast period and factor in the data for each updated period within it.

Performing these comparative analyses will enable your team to quickly make changes to your existing plans and budgets and help refine your process for the future rolling forecasts.

Go With a Phased Approach

In most situations, change brought on abruptly isn’t well-received and creates chaos on all levels. It’s best to start small with a few departments and gradually involve more participants to improve your methods while making them more refined and efficient. Doing so will enable you to create a tried-and-tested method for achieving better results through rolling forecasts and hence demonstrate the value of implementing this new approach to key stakeholders.

Each iteration must involve continuous improvement so that effective SOPs can be developed and changes in the process can be introduced if the need arises. The goal is to learn and improve from what happened and why it happened and determine what can be done to create more accurate forecasts.
