The Importance of Demand Forecasting

What is Demand Forecasting? The Details You Need to Know

Countless variables can affect how much product you will sell in a given period. 

While it’s impossible to predict all of the aspects that could impact sales performance, businesses using demand forecasting have been able to make informed and accurate decisions about the future, as well as their current inventory needs. 

But what is demand forecasting? And how should you forecast demand for your business? 

We answer these and other questions in this blog post. First, let’s look at the meaning of demand forecasting. 

What Does Demand Forecasting Mean? 

As the name implies, demand forecasting is the process of forecasting the future consumer interest in your product and/or services. 

The demand planning and forecasting methodology uses your historical sales performance, seasonal trends, and other relevant data to make educated guesses about what your sales might look like in both the near and the long-term future.

The ability to plan warehousing, inventory, and budgeting decisions for fulfillment services is a massive advantage. It allows companies to maintain stock products while also not overspending on overhead costs associated with having too much product inventory that can’t move quickly.

While forecasting demands with complete accuracy may not be possible, today’s demand forecasting techniques and best practices have allowed businesses to create more precise forecasts than ever. 

The best perk of using the process is that, with every year of applying demand forecast models and methods, companies can accumulate more data, adjusting for past discrepancies and continually improving performance within their forecasting and demand management operations. 

Importance of Demand Forecasting

Demand drives all businesses. Therefore, it’s not surprising that the ability to have accurate demand planning and forecasts can have a massive impact on your business as well. 

But why is demand planning and forecasting important? Let’s examine a few demand forecasting examples. These will highlight how this practice impacts your business decisions.


Setting prices is an integral part of running a business. You need to figure out the right markup in your situation, considering the current market activity and the demand for your product. 

With the help of demand forecasting, you can accurately estimate when your products will be the most popular, make adjustments to your price, and make the most of opportunities when demand is high and supply in the market is low. 

At the same time, when you know a dip in demand is coming, you can lower your pricing and sell off some of your inventory.  This can provide you with more cash flow and reduce your overhead costs for that period. 


Another reason demand planning is so important is due to the vital part it plays in planning a budget. For businesses, ensuring consistent cash flow and efficient resource allocation is always a top priority.

Sound forecasting and demand management can be the difference between taking advantage of growth opportunities and facing serious issues. This is especially true when demand is low, and you need to have resources allocated to survive the downturn in revenue. 

Optimizing Inventory

A final demand forecasting example includes how to use it for optimizing inventory. A good grasp of your inventory needs is one of the best ways to maximize how you use the available resources.

On the one hand, you want to keep your inventory costs low and only stock up as much as necessary. But at the same time, you must be able to handle demand surges. Running out of stock in the middle of a buying frenzy can seriously damage not just your bottom line but your reputation as well. 

Demand Forecasting Models

To make the most of what supply and demand planning can offer, it’s essential to understand the different types and uses of demand forecasting that can be applied in different situations.

Passive & Active

Passive demand forecasting is ideal for businesses that don’t plan for rapid expansion, using historical data in a limited scope. Meanwhile, active demand forecasting considers more factors, such as external conditions and changes and even the economy. 

Micro & Macro

At the macro level, demand forecasting looks at the entire market and analyzes the shifts and trends occurring. Micro-level demand forecasting in supply chain looks at the business itself, examines its processes, and uses that data to predict future patterns. 

Short & Long Term

Finally, you can use supply and demand planning to look at different time periods. With short-term demand forecasting, you look at the upcoming months, while long-term forecasting covers multiple years.

What are the Demand Forecasting Techniques? 

There are two main demand planning and forecasting approaches that can help you determine how to forecast demand more accurately. Depending on your business situation, size, and the sample size of historical data, you may find that some methods are more suitable for your business than others.

First are quantitative methods, which are based on historical or current data. This involves looking at the data from the past few years, or even the existing data, and interpreting it to provide you with demand forecasts about likely future performance with your fulfillment services. 

Quantitative demand forecasting uses advanced models such as the autoregressive integrated moving-average, fine-tuning the equation to account for the historical representation. Then, inserting the specific numbers to produce a forecast. 

Another approach is the qualitative demand forecasting method, which relies on opinions from experts either outside or within the company to generate multiple forecasts and then synthesize them to produce a final result.

Quantitative forecasting can also employ surveys of the target audience, which can provide insights that might be missed by people within the forecasting and demand management organization. However, one of the more significant demand planning constraints with this approach is the difficulty of ensuring the survey is an accurate representation of your audience.
