Master Amazon Inventory Forecasting: Avoid Stockouts & Save on Storage Fees

July 15, 2026 · Seller AI

Effective inventory forecasting is crucial for Amazon sellers aiming to avoid stockouts and minimize long-term storage fees. Discover actionable strategies to optimize your stock levels and reduce costs.

Inventory management is one of the most challenging aspects of running an Amazon business. Striking the right balance between having enough stock to meet demand and avoiding overstocking, which leads to long-term storage fees, is a delicate dance. Here are some practical strategies to master inventory forecasting on Amazon.

Understanding Amazon Storage Fees

Amazon charges long-term storage fees for inventory that has been in a fulfillment center for more than 365 days. These fees can add up quickly, so it's essential to understand them and plan accordingly. For standard-sized items, the fee is $11.25 per cubic foot, while for oversize items, it's even higher at $22.50 per cubic foot. By forecasting demand accurately, you can reduce the risk of incurring these fees.

Using Amazon's Inventory Performance Dashboard

Amazon provides a tool called the Inventory Performance Dashboard that gives sellers insights into their inventory health. It shows you the performance of your products in terms of sales velocity, excess inventory, and storage fees. Use this tool to identify products that are at risk of being charged long-term storage fees and adjust your inventory accordingly.

Implementing Inventory Forecasting Techniques

There are several forecasting techniques you can use to predict demand more accurately:

• Moving Average: This simple method averages the sales data over a period to predict future demand.
• Exponential Smoothing: This method gives more weight to recent sales data, making it more responsive to changes in demand.
• Seasonal Adjustment: For products with seasonal demand, this method adjusts the forecast to account for seasonal fluctuations.

Choose the method that best fits your product's sales pattern and update your forecast regularly to keep it current.

Adjusting for Promotions and Trends

Promotion periods, such as Black Friday or Prime Day, can significantly impact your sales. Make sure to adjust your forecasts to account for these spikes in demand. Also, be aware of market trends that might affect your product's demand. For example, if a popular product is being discontinued, you might see increased demand for similar items.

Using AI for Inventory Forecasting

AI-powered tools can help automate and improve the accuracy of your inventory forecasting. These tools can analyze vast amounts of data, including historical sales, seasonal trends, and market conditions, to provide a more accurate forecast. By integrating AI into your inventory management, you can reduce the risk of stockouts and overstocking.

For example, Amazon's own AI service, Inventory Labs, helps sellers optimize their inventory levels. It takes into account factors like sales velocity, storage fees, and upcoming promotions to predict optimal inventory levels and avoid stockouts or excess inventory.

Another AI solution is Seller AI, which offers a suite of AI agents designed specifically for Amazon sellers. These agents can automatically adjust your inventory according to predicted demand, helping you avoid stockouts and reduce storage fees. With Seller AI, you can focus more on growing your business while letting the AI handle the inventory forecasting.
