Activity-Based Costing (ABC) is a managerial accounting method that assigns overhead (indirect) costs to products and services more accurately by first identifying specific activities, then tracing the resources consumed by those activities, and finally allocating costs to outputs based on how much each product or service uses those activities, rather than just volume-based metrics like labor hours. This provides a clearer picture of true product profitability, helps pinpoint inefficiencies, and improves decision-making for pricing and process improvement.
