This document provides an analysis and comparison of traditional costing and activity-based costing (ABC) systems using two Pakistani companies, Atlas Honda and Nishat Mills, as examples. For Atlas Honda, traditional costing results in higher per unit costs than ABC costing. For Nishat Mills' textile products, traditional costing also yields slightly higher per unit costs than ABC costing. The document concludes that ABC costing provides a more accurate allocation of costs based on cost drivers and generally results in lower reported per unit costs for products.
