Calculating Projected Sales: FP&A Leaders’ Guide

This concise guide will help FP&A executives become skilled at estimating projected sales. This is incredibly important because it drives business growth and maximizes earnings. By using this guide, you can improve your ability to predict future outcomes, strengthen strategic planning, and play a key role in the overall success of your enterprise.

The Sequential Unfolding of Sales Projections

Consider this: as sales forecasts guide management in setting sales quotas, the HR department can leverage these quotas to ascertain the required number of new hires. This phenomenon sets off a chain reaction, and it all originates from the core of sales projections.

Equally crucial is the role of revenue forecasting in budget formulation. With an estimate of the company’s prospective sales, the finance team can determine the necessary allocation of funds for aspects like production, storage, and transportation expenses.

Crucial Elements Shaping Sales Forecasting

While we have control over certain aspects like pricing and marketing, there are many other factors that we cannot control, such as the state of the economy and changes in the industry. To accurately predict future revenue, we need to consider all these different factors together.

Paramount Considerations for FP&A

1. Past Sales Data

Crafting a precise projection is greatly enhanced through an analysis of past sales. By digging into historical sales data, you can scrutinize the impact of specific variables—such as pricing or seasonality—on previous sales patterns.

It’s reasonable to anticipate the persistence of these trends (though upcoming sales revenue might be influenced by varying factors).

2. Market Trends

Should there be a decline, identifying the reasons can aid in capturing a more substantial portion of the market share. Conversely, if there’s an upward trend, it’s reasonable to infer that your competitors are also expanding. How exactly are they addressing the rising demand?

3. Competitive Landscape

For an accurate sales projection, enterprises must engage in a comprehensive assessment of their competitors. It’s important to pinpoint the intersections between your business and others regarding customers and communication strategies.

4. Understanding Customer Behavior and Preferences

Understanding your target audience is a crucial step in understanding sales. This information is extremely valuable when creating advertisements. By evaluating the effectiveness of these ads, you can make more accurate sales projections.

5. Economic Factors

Certainly, the economic terrain will significantly shape revenue forecasts. It’s imperative to establish a distinct correlation between metrics such as GDP, inflation, and the performance of your product.

Collecting Information for Sales Forecasting

After evaluating the elements that could influence forthcoming sales, the next step involves collecting the data to be incorporated into your sales projections. This data should be acquired from both internal and external sources for a comprehensive approach.

  • Internal Data

To start with sales forecasting, it’s helpful to analyze previous sales data. This data gives valuable insights and forms the foundation for most forecasting methods. For example, by looking at how many units were sold during a specific time last year, we can estimate sales for the coming year.

Additionally, qualitative customer data is crucial. It’s important to engage with customer representatives and sales teams to gain a deeper understanding of customer perspectives and what influences their buying decisions. We’ll discuss this in more detail later.

  • External Data

Pay attention to economic signals like the consumer price index (CPI), which shows how the prices of household items change on average (a measure of inflation).

It’s also important to keep a close eye on industry benchmarks and comparisons. This will ensure that you’re not falling behind your competitors and will validate the accuracy of your revenue predictions.

Lastly, thorough market research reports provide a detailed analysis of your industry. Going through these reports is one of the best ways to gather data for your sales forecasts.

Sales Forecast Methods

Sales forecasts can be categorized into two primary forms: quantitative and qualitative approaches.

Quantitative approaches rely on—you’ve got it—numerical data! This data might encompass historical records, macroeconomic measures, and sector-specific cues, among various others.

Conversely, qualitative methods center on the viewpoints of those intimately engaged in sales operations or the overall company/industry. While quantitative methods are objective, qualitative methods adopt a subjective stance.

Quantitative Methods

1. Time-Series Analysis

Sales projections are derived from historical data through time-series analysis. A time series comprises regularly recorded data points over time, often on a monthly or quarterly basis. These data points can be visualized using a line chart. Subsequently, the analysis process commences.

Numerous forms of time-series analyses exist, with the most fundamental being the naive method. This technique projects forthcoming values by extending the present trend line, disregarding any other factors or alterations in the data.

2. Statistical Models

In sales forecasting, various primary statistical models are commonly utilized. This method examines a designated window of past data, such as the preceding three months. For instance, when determining the sales value for the 25th month, the average of sales from months 22, 23, and 24 would be computed.

Subsequently, there is exponential smoothing. Exponential smoothing places greater emphasis on recent sales figures under the assumption that they are the most pertinent to the current market conditions.

Lastly, there is ARIMA combines both autoregressive and moving average components, enabling it to capture and analyze the underlying patterns and oscillations present in time-series data affected by seasonal changes.

3. Regression Forecasting

Regression forecasting involves the exploration of the connection between sales and particular variables, such as price or customer behavior. Within this computation, sales represent the dependent variable, whereas the elements influencing sales constitute the independent variables.

4. Market Share Method

The market share method employs a top-down strategy for sales forecasting, commencing with the overall size of the (reachable) market that holds potential interest in your product.

To compute the total market demand, the quantity of purchasers is multiplied by their typical consumption within your industry. Subsequently, your own market share is approximated.

Market share is influenced by a myriad of factors, encompassing competition, pricing, product distinctiveness, marketing endeavors, and customer preferences, all of which can be challenging to predict with certainty.

Qualitative Methods

1. Intuitive Method

Your sales team possesses unparalleled insight into your sales cycle.

On occasion, soliciting the sales team’s input regarding the probability of specific deals reaching fruition can assist in approximating anticipated sales.

Nonetheless, there exists the possibility that their optimism might be excessive, underscoring that the intuitive approach shouldn’t be the sole foundation on which you place your reliance.

2. Jury of Executive Opinions

Managers usually have a good understanding of what happens in their departments. The “jury of executive opinions” method involves managers from different departments, like sales, marketing, finance, and production, coming together to discuss sales-related matters. They then work together to reach a collective agreement, considering each department’s contribution to the overall sales process.

3. Delphi Method

The Delphi method encompasses engaging external industry experts in consultation. Initially, each individual formulates their independent projection of future sales.

The value of expert perspectives lies in their ability to shed light on variables that are intricately challenging to quantify, such as impending technological advancements, dynamic shifts in consumer preferences, and evolving behaviors.

Optimal Approaches for Forecasting Sales Revenue

Discover these strategies to improve your ability to predict future sales, make better decisions, and achieve better outcomes for your business. By using these proven approaches, you can gain a better understanding of sales trends, make smarter choices, and achieve more success in your business.

  • Utilize a variety of forecasting approaches

Opting for a single forecasting technique is not mandatory. Instead, it is advisable to employ a minimum of two methods to attain a more comprehensive understanding of your circumstances.

  • Utilize your typical monthly sales pace as a reference point

Compute your standard monthly sales pace, a valuable yardstick for appraising sales achievements and monitoring advancement as time passes. By deriving the mean monthly sales pace, you can contrast it with existing sales figures to determine if you are achieving, surpassing, or lagging behind your established starting point.

  • Segment by product category or unit

Segmenting by product category will be a lot easier than attempting to forecast your entire company. You should also consider making forecasts based on units rather than monetary values (such as dollars, pounds, yuan, etc.). This approach offers greater granularity and assists in refining your focus on specific factors like product demand, pricing tactics, customer preferences, and market saturation.

  • Dividing based on product category or individual units

Opting for segmentation by product category offers a simpler approach compared to trying to predict the overall company performance. This approach offers greater granularity and enables you to focus on precise factors like product demand, pricing tactics, customer inclinations, and market saturation.

  • Consider external trends and seasonality

Remember that there’s so much more to forecasting sales than your own capacity. For instance, alterations in consumer inclinations, advancements in technology, or changes in the competitive environment can directly influence sales outcomes. By staying informed about these external trends, you can adjust your forecast accordingly.

  • Make Adjustments Based on Predicted and Actual Results

While achieving complete precision in sales projections is unlikely, you can enhance the reliability of your sales forecasts by examining the disparities between projections and actual outcomes. Evaluate the underlying reasons for any discrepancies and apply essential modifications accordingly.

  • Adjust Forecast to Match Actual Results and Changes

Ensure that your forecasts remain precise by adapting them to match actual outcomes. Remember to also incorporate adjustments into your projections for any intended alterations, such as price adjustments, workforce expansion, or heightened marketing endeavors.


A sales forecast plays a crucial role in influencing investment choices and strategizing territory allocation. When you can reasonably anticipate that a specific sales endeavor in a particular region will yield significantly better returns than other options, you’ll be inclined to prioritize it. Adhering to these steps offers a reliable method to enhance your forecasting accuracy. Nevertheless, for optimal efficiency, it’s advisable to harness appropriate technology.
