Historical company performance, industry growth rates, and economic indicators heavily influence top-down forecasting. The charm of top-down forecasting lies in its knack for weaving a cohesive narrative of a company’s financial future, grounded in its strategic goals and aspirations. Once the overall projections are established, they’re divvied up among individual departments, teams, or product lines. These projections shape detailed sales budgets and production capacity plans.

Top-Down Forecasting Strengths: When It Shines

Human analysts interpret this data, making adjustments that automated systems might miss. Predictive analytics can further improve forecast accuracy by considering historical data and market conditions. We will also discuss the importance of market research and historical data in forecasting demand. Regularly measuring and refining your approach is crucial for staying on target and adapting to market changes. This involves tracking key performance indicators (KPIs) and iteratively adjusting your forecasting strategy.

Top-Down vs Bottom-Up Forecasting: Understanding the Fundamentals

Their insights can be invaluable in identifying potential opportunities and challenges that might not be apparent from the data alone. By leveraging detailed data from individual units, your financial models can offer a more precise and realistic forecast. This level of analysis provides a more nuanced and accurate forecast, enabling your business to make more informed decisions. While bottom-up forecasting offers significant advantages, it also presents challenges. The detailed nature of this method requires substantial time and resources. Gathering data from individual sales representatives or teams can be labor-intensive, especially for larger organizations.

• If you are also forecasting at the customer level, then the levels of aggregation multiply by the customer dimension.
• But, by understanding these hurdles, you can take steps to mitigate them and improve the accuracy of your forecasts.
• That being said, using a hybrid approach of both top-down and bottom-up forecasting has proven to be successful for many businesses.

All of which, are informed by their knowledge of the market, customer demands, and in-house capabilities. Once these customized forecasts are wrapped up, they’re woven together to form a comprehensive financial tapestry for the entire organization. We can explain the methodology to model financial statements based on bottom up approach using a hypothetical example of a retail company named Maxmart Ltd. We first need to identify the key revenue drivers from the financial statements or annual report of the company. In the retail company the common revenue drivers are Revenue per square foot, Order frequency and average order value. You can download the template of a bottom-up forecasting financial model for you to be able to practice on your own as well.

These include industry reports, government data, or data from third-party sources. While top-down forecasting does have some advantages, it does offer a few disadvantages that you must take into consideration. We have talked immensely about bottom-up forecasting, its importance, uses, and benefits.

In doing so, you can help your sales reps become more confident in their work and boost their sales productivity. They must look at all their sales channels to analyze the number of expected orders coming from each. With products or services at different price points, they’ll need to determine the average cost, considering things like discounts or promotions. However, they may add other variables into their model, like returns, refunds, and exchanges. Every organization is unique and requires the right inputs for an accurate forecast.

The forecasted results are then added together to generate a total forecast. Bottoms-up forecasting isn’t just a number-crunching exercise—it’s your roadmap to better decisions and smarter business growth. By starting from the ground up, this method gives you a tailored, actionable plan that reflects your actual operations, not just high-level guesses. By focusing on detailed data, bottoms-up forecasting directly informs revenue generation and business growth.

• For businesses dealing with high volumes of data, a platform like HubiFi can streamline this process, ensuring you have the right data at your fingertips.
• Set a regular cadence for review, whether it’s monthly, quarterly, or annually, to stay on top of changes and maintain the accuracy of your projections.
• Bottom-up sales forecasting involves analyzing detailed data at the ground level.
• Similarly, a bottom-up approach helps leaders examine various aspects of their organization compared to their competitors.

Since this method relies on input from various units within the organization, fostering a culture of open communication and data sharing is essential. For instance, sales teams can provide insights into customer behavior, while production units can offer data on manufacturing capabilities. This collaborative approach ensures that the forecast is grounded in the realities of each department, leading to more accurate and actionable predictions.

Top-down forecasting cons:

This article on revenue forecasting offers a helpful comparison of these two methods. For SaaS companies, top-down sales forecasting typically begins with analyzing the total addressable market (TAM) for their software category. This approach works particularly well for new product launches or market expansions where historical sales data may be limited. Artificial intelligence (AI) and machine learning (ML) are also playing an increasingly important role in forecasting. These technologies can analyze complex datasets to identify patterns and trends that might be missed by traditional methods.

Wall Street Prep describes the top-down approach as estimating “future sales by applying an implied market share percentage to a total market size estimate.” (see formula image below). The retail company in our example also generates e-commerce revenue and revenue from other sources. Instead of Bottom up approach we have forecasted the future e-commerce and other revenue at an average growth rate of last 5 years’ e-commerce and other revenue. Year-over-Year analysis is the simplest method of forecasting where an analyst will look at historical growth rates and apply a growth rate percentage to historical revenue.

Step #1 – Your Company’s Financial History

Put another way, bottom-up forecasting is like looking at the health of a complex system, like a vehicle, by looking first at its most basic parts, like its engine components. You can change your settings at any time, including withdrawing your consent, by using the toggles on the Cookie Policy, or by clicking on the manage consent button at the bottoms up forecast bottom of the screen. Investors, board members, or even your own boss questioning every single assumption. If your forecast feels more like a court case than a planning tool, you’re not alone. Using incomplete, outdated, or flat-out wrong inputs can sabotage your projections before they even leave the ground. Armed with a rock-solid bottoms-up forecast, the company made bold but calculated moves.

To wrap up the revenue projection assumption linkages, we now grow the total number of orders using XLOOKUP again. The ASP of an individual product comes out to about $100 in 2018, which grows to around $105 in 2020. We’ll now move on to a modeling exercise, which you can access by filling out the form below. Another potential drawback is that the approach increases the probability of receiving scrutiny from outside parties like investors.

Combining Bottom-Up with Other Forecasting Methods

Multiply your quantity projections by pricing to determine your gross revenue. For the Equity we are assuming that the common stock amount remains constant as the company does not raise any further capital through issue of shares. Long-term debt for the forecasted period of 5 years is assumed to be constant as the closing long-term debt balance at the end of year 2023. Hence, we are assuming that the company is not raising any new debt and not paying off the existing debt. Other current assets and liabilities are assumed to be similar to the last historical year. With the refund forecast filled out, we can move on to calculating net revenue, which accounts for the refunds and avoids double-counting.

The Advantages of Middle-Out Forecasting

You’ll get a lot of valuable insights to develop effective marketing campaigns. Bottoms-up forecasting is a forecasting method that starts with the lowest level of detail (e.g., individual salespeople) and works toward the top (e.g., total sales). With this method, you first break down the total sales target into the smallest individual units and then do a forecast for each unit.
