Inventory Aging Report: What is it and How to Calculate It

Unsold stock piling up in your warehouse can quietly drain your business’s money. This often overlooked problem not only ties up cash but can also lead to outdated inventory that is harder to sell.

An inventory aging report is a helpful solution that shows the age of your stock, helping companies manage their inventory better. By pointing out slow-moving items, businesses can take action before these items become a bigger issue.

This article will explain what an inventory aging report is and its benefits. We will explore how using this tool can help with better inventory planning, making sure your business stays profitable and efficient.

What is Inventory Aging Report?

An inventory aging report shows how long items have been in stock. It works by categorizing inventory into different age groups, helping businesses identify which items are slow-moving inventory.

This report breaks down inventory into time frames, such as 30 days, 60 days, and 90 days. Each group shows how long products have been sitting in your warehouse, giving a clear picture of stock age.

Using this report, businesses can see which items need to be sold quickly and which ones are moving well. This helps in making better decisions on purchasing and sales strategies.

With regular use, an inventory aging report can improve cash flow and reduce wasted stock. It is an important tool for maintaining a healthy inventory and ensuring your business runs smoothly.

One of the tips to maintain effective inventory management is by using an inventory system. This system can automatically generate report with high accuracy, helping inventory management to stay efficient.

Why You Need Inventory Aging Reports for Your Business

Inventory aging reports offer several benefits that can significantly improve your business operations. By understanding the age and movement of your stock, you can make informed decisions that enhance efficiency and profitability.

Here are the key benefits of using inventory aging reports:

1. Identify slow-moving inventory: This report helps identify slow-moving inventory. By spotting items that are not selling well, you can take action to discount or promote these products before they become obsolete.
2. Disconnect between sales and inventory: These aging inventory reports reveal the disconnect between sales and inventory. If sales data doesn’t match up with what’s in stock, it highlights inefficiencies and areas that need attention.
3. Dead inventory strategy: An inventory aging report aids in developing a strategy for dead inventory. Items stuck in stock for too long can be labeled as dead stock and managed through offers like bundling, clearance sales, or special promotions. In the food industry, goods that go beyond a few weeks can be marked as dead or expired and require immediate action.
4. Carrying, overhead costs, and opportunity costs: These aging inventory reports help manage carrying, overhead, and opportunity costs. By reducing excess stock, you lower storage costs and free up capital for other business opportunities.
5. Reduced liquidity & margins: They assist in identifying reduced liquidity and margins. Old inventory ties up funds that could be better used elsewhere, impacting your business’s financial health.
6. Waste and environmental impact: Inventory aging reports can reduce waste and environmental impact. By managing stock more efficiently, you minimize the risk of disposing of unsold goods, contributing to a more sustainable business practice.

How to Calculate Inventory Aging

Calculating an aging inventory report involves several key formulas that provide valuable insights into your inventory management. By understanding these calculations, you can better manage your stock and improve your business efficiency.

Here are the essential calculations you need to know, also with inventory aging report formula:

1. Average Inventory Cost

The average inventory cost shows the value of your stock over a certain period. It helps balance out the ups and downs in inventory due to seasonal changes or different shipping schedules, giving a clear view of your overall inventory value.

To calculate average inventory cost, use this formula: Average inventory cost = annual COGS / total ending inventory

2. Cost of Goods Sold (COGS)

COGS represents the total cost of producing the goods sold by a business. This includes direct costs like materials and labor, as well as indirect costs such as overhead.

To calculate COGS, use this formula: COGS = (beginning inventory + purchases) – ending inventory

The beginning inventory is the stock you have at the start of the period, and the ending inventory is what remains unsold at the end.

3. Inventory Turnover Ratio (ITR)

The ITR shows how often a business sells and replaces its inventory within a certain period, usually a year. This ratio helps businesses decide on pricing, marketing, and restocking strategies.

To calculate ITR, use the following inventory aging report formula: ITR = COGS / average inventory value

A lower ITR might mean you have too much stock or weak sales, while a higher ITR could indicate strong sales or not enough inventory.

4. Average Inventory Age

Average inventory age measures how long it takes, on average, to sell your inventory. This metric, also known as days sales in inventory (DSI), helps you understand your stock turnover rate.

To calculate average inventory age, use this formula: Average inventory age = (average inventory cost / COGS) x 365 days

Inventory Aging Report Example

Let’s illustrate the aging inventory report example. Suppose your electronics store has an average inventory cost of $200,000, and your COGS is $600,000. Using the formula, your average inventory age would be calculated as follows:

Average inventory age = ($200,000 / $600,000) x 365 days

Average inventory age = approximately 122 days

A higher average inventory age means products are taking longer to sell, leading to higher holding costs. Conversely, a lower average inventory age indicates strong customer demand, requiring timely reordering to maintain stock levels.

Typically, a good average inventory age ranges between 60 and 90 days. However, if an item remains unsold for 180 days or more, it is often considered dead stock.

5 KPIs for Inventory Aging

Tracking the right key performance indicators (KPIs) is crucial for managing inventory efficiently. Here are five essential KPIs that can help you gauge the health of your inventory aging:

1. Inventory Turnover Ratio

This KPI measures how often your inventory is sold and replaced over a period. A higher turnover ratio indicates efficient inventory management, showing that items are sold quickly and restocked efficiently.

2. Percentage of Inventory Aging

This metric shows the percentage of your inventory that has been in stock for a long period. It helps identify products that are at risk of becoming obsolete, enabling proactive management decisions.

3. Carrying Costs

These are the total costs associated with holding inventory, including storage, insurance, and employee costs. Monitoring these costs is vital to ensure they do not eat into your profit margins excessively.

4. Percentage of Slow-Moving Inventory

This indicates the proportion of inventory that moves slower than expected. It is calculated with the formula: (Value of Slow-Moving Inventory / Total Inventory Value) x 100

5. Inventory Carrying Cost as a Percentage of Revenue

This KPI helps understand how much of your revenue is being spent on carrying inventory. It is especially important for assessing whether the cost of holding stock is aligned with your business revenues. Formula: (Inventory Carrying Cost / Total Revenue) x 100

Need to Know

In Singapore, inventory aging analysis shows that approximately 40% of retail businesses experience overstock issues, which results in products remaining unsold beyond the ideal 90-day threshold, directly impacting their liquidity and space management.

Tips for Reducing Aging Inventory

Reducing aging inventory is crucial for maintaining operational efficiency and profitability. By implementing strategic practices, businesses can minimize the financial impact of unsold stock. Here are effective tips to help manage and reduce aging inventory:

1. Generate Accurate Demand Forecasts: Use historical sales data, market trends, and seasonal fluctuations to predict future product demand accurately. This helps in maintaining optimal stock levels and reducing excess inventory.
2. Master Strategic Inventory Planning: Develop a robust inventory plan that aligns with your sales goals and market demand. This involves scheduling purchases wisely and considering lead times to prevent overstocking.
3. Optimize Retail Prices: Regularly review and adjust your pricing strategy based on inventory age and market demand. Promotional pricing or discounts can help move older stock faster and free up warehouse space.
4. Optimize Warehouse Management: Enhance your warehouse layout and organization to facilitate easy access and movement of older stock. This includes better shelf labeling, improved inventory grouping, and regular audits to identify slow-moving items.
5. Invest in Inventory Automation Tools: Implement advanced inventory management system to gain real-time insights into your inventory levels. This technology helps in making informed decisions and improves overall inventory turnover. Download the price scheme of the best inventory software in Singapore below.
