What Is ABC Analysis?

ABC analysis is a proven inventory management technique that classifies items into A, B, and C categories based on their annual consumption value (ACV)—a calculation of price multiplied by annual usage.

A items: High-value products that contribute roughly 70–80% of total inventory value but make up only a small portion of total stock.
B items: Moderate-value products that account for the next 15–20% of value.
C items: Low-value products that represent the remaining 5–10% of value but are often the most numerous.

This ABC inventory management calculation helps businesses focus resources where they matter most. It’s a cornerstone of supply chain management and procurement planning, enabling better purchasing decisions, tighter stock control, and improved cash flow.cy.

Q: What is ABC Analysis?

ABC Analysis is an inventory management technique used to categorize items based on their value to the business. It divides inventory into three categories: A items : High-value items that contribute to around 80% of total inventory value but are smaller in number. B items : Moderate-value items that account for about 15% of inventory value. C items : Low-value items that make up only 5% of the inventory value but typically represent the majority of items in stock. This classification helps businesses prioritize their focus, ensuring they manage high-value items more closely and efficiently.

Q: How to Perform ABC Analysis?

Gather Data : Collect data on each item, including its price and quantity sold. Calculate Annual Consumption Value (ACV) : Multiply the price of each item by the quantity sold over a specific period (e.g., annually). ACV = Price * Qty Sold Sort Items by ACV : Arrange items in descending order based on their ACV. Cumulative ACV : Calculate the cumulative percentage of total ACV for each item. Categorize : A items : Top 80% of cumulative value. B items : Next 15%. C items : Remaining 5%. By performing this analysis, you can identify which items require more attention and resources for effective inventory management.

Q: Why is ABC Analysis Important for Inventory Management?

ABC Analysis is critical because it helps you: 1) Optimize your resources . Not all inventory items are equally important. By focusing on the A items , you can: 2)Reduce stockouts : Ensure high-value items are always available. 3)Lower carrying costs : Avoid overstocking lower-value C items . 4)Improve decision-making : It provides data-driven insights on how to allocate time, effort, and resources, improving overall inventory efficiency and profitability. Effective ABC Analysis can also lead to better demand forecasting and supplier negotiations for critical items.

Q: What are Common Mistakes in ABC Analysis?

For More Detailed understanding Check out our Blog on " Top ABC Analysis Mistakes to Avoid in Inventory Standardization " Relying Solely on Value : Some businesses focus only on the financial value of items and ignore turnover or demand, leading to misclassification. Infrequent Updates : Inventory data is dynamic. Performing ABC Analysis only once a year might overlook changes in demand patterns. Overstocking C Items : It’s tempting to overstock C items because they are inexpensive, but this increases holding costs and clutters the warehouse. Neglecting B Items : While A items are the primary focus, B items also contribute significantly to sales. Ignoring them can lead to missed opportunities.

Compact table view

How to Interpret:

A Items (Top ~80% value): High-value, low-qty. Tight control.
B Items (Next up to ~95%): Medium value. Monitor regularly.
C Items (Remaining): Low value. Simple controls.

Prioritize effort by value contribution, not count.

ABC Analysis Formula

The ABC analysis formula is the calculation used to determine each item’s annual consumption value (ACV) and assign it to category A, B, or C.

Formula:

ACV = Unit Price × Annual Quantity Used

How it works:

Calculate the ACV for each product.
Sort products in descending order of ACV.
Calculate the cumulative ACV percentage.
Classify:
- A items: Top ~80% of total value.
- B items: Next ~15% of total value.
- C items: Remaining ~5% of total value.

This calculation is the foundation of ABC inventory management calculation. It’s used in supply chain management and procurement to focus attention and resources on the most valuable stock items. With our ABC analysis calculator online, the formula is applied instantly, so you don’t have to do the math manually.

ABC Inventory Classification Explained:

ABC Analysis segments your inventory based on its contribution to annual consumption value. By classifying items into categories A, B, and C, businesses can prioritize their inventory management efforts more effectively. This strategic approach helps ensure that high-value items are closely monitored, while lower-value items are managed more efficiently—ultimately improving overall stock control and resource allocation.

A Items – High Priority

These are the most valuable items in your inventory.

Typically represent 10–20% of total items
Contribute around 70–80% of total inventory value
Require strict control, accurate forecasting, and frequent reordering
Best suited for continuous tracking and real-time decision-making

Focus on avoiding stockouts and ensuring high availability.

B Items – Medium Priority

B items strike a balance between volume and value.

Usually make up 20–30% of items
Account for about 15–25% of inventory value
Require moderate control with monthly or quarterly review cycles
Ideal for semi-automated inventory systems or rule-based replenishment

Focus on controlling costs without compromising availability.

C Items – Low Priority

These are low-value items present in large quantities.

Comprise 50–60% of total inventory
Contribute only 5–10% of overall value
Require basic control and infrequent reordering
Best managed in bulk with minimal administrative effort

Focus on minimizing time and resources spent on low-impact stock.

ABC Analysis in Supply Chain Management

In supply chain management, ABC analysis is more than just an inventory control technique—it’s a decision-making tool that drives efficiency across procurement, warehousing, and distribution.

Here’s how it adds value:

Inventory prioritization: Focus attention on A items, ensuring high availability and minimizing stockouts.
Optimized resource allocation: Assign manpower, budget, and storage space based on item category.
Better purchasing strategy: Place frequent, smaller orders for A items; bulk or less frequent orders for C items.
Improved demand forecasting: Understanding category patterns helps align supply with demand.

Businesses use ABC inventory management calculation to reduce carrying costs, improve turnover rates, and maintain service levels without overstocking. In competitive supply chains, knowing exactly which products have the greatest financial impact can be the difference between profit and loss.

History of ABC Analysis

The concept behind ABC Analysis originates from the Pareto Principle, first introduced by Italian economist Vilfredo Pareto in 1896. He observed that approximately 80% of outcomes arise from just 20% of causes—a phenomenon that has since been found to hold true across various fields, including economics, business operations, and inventory management.

Building on this insight, Dr. V. F. Ridgeway formalized the concept into what we now know as ABC Analysis during the 1950s. By classifying inventory based on annual consumption value, this method enables businesses to prioritize their efforts, ensuring that the most valuable items (typically the A-class) receive the most attention, while less critical items (B and C classes) are managed with proportionate resources.
