What is Economic Order Quantity (EOQ)?
Economic Order Quantity represents the ideal order size that minimizes total inventory costs by balancing ordering and holding expenses. Developed by Ford W. Harris in 1913, EOQ remains a cornerstone of inventory management for businesses worldwide. For CMA students, mastering EOQ is crucial as it appears frequently in Cost Accounting papers, helping optimize procurement strategies.
Companies like Walmart and Amazon apply EOQ principles to handle millions of SKUs efficiently, reducing waste and ensuring product availability. In India, manufacturing firms and retailers use EOQ to navigate supply chain challenges amid fluctuating demand and costs.
EOQ Formula and Key Components
Where:
D = Annual Demand (units)
S = Ordering Cost per Order (₹)
H = Holding Cost per Unit per Year (₹)
The formula derives from equating total ordering cost (D/Q × S) and holding cost (Q/2 × H), finding the point where their sum is minimized. CMA exams often test variations including quantity discounts and backorders.
Understanding Variables with Example
| Variable | Description | Example Value |
|---|---|---|
| D (Demand) | Units required yearly | 12,000 units |
| S (Ordering Cost) | Cost per purchase order | ₹500/order |
| H (Holding Cost) | Storage cost per unit/year | ₹10/unit |
Plugging values: EOQ = √[(2 × 12,000 × 500) / 10] = √[1,200,000] ≈ 1,095 units per order.
Assumptions and Limitations of EOQ Model
EOQ assumes constant demand, instantaneous replenishment, and fixed costs – ideal for stable environments but less suited for perishable goods or volatile markets. Limitations include ignoring lead times, quantity discounts, and demand variability common in Indian retail.
- Demand remains steady throughout the year.
- No shortages or backorders allowed.
- Holding costs are linear with inventory levels.
Real-World EOQ Applications
Walmart uses EOQ for fast-moving consumer goods, ordering optimal quantities to minimize stockouts while controlling warehouse costs. In manufacturing, Toyota applies EOQ variants in Just-In-Time systems. Indian examples include FMCG firms like Hindustan Unilever optimizing distributor orders.
For CMA professionals, EOQ aids in supplier negotiations and working capital management, directly impacting profitability.
EOQ in CMA Syllabus
EOQ features prominently in CMA Intermediate Paper 8 (Cost Accounting), covering basic model, EBQ (Economic Batch Quantity), and integrations with ABC analysis. Part 2 includes advanced applications in decision-making and risk management. Practice problems test total cost minimization and sensitivity analysis.
