Accuracy and Limitations
Use balances and COGS from the same period and costing method. Seasonality, write-downs, consignment, stockouts, and product mix can distort a simple average.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
