Weighted Average Cost Accounting Formula (WACAF) is an accounting technique that can help businesses, organizations, and institutions achieve greater efficiency and effectiveness in their budgeting. WACAF calculates the average cost of items or services, taking into account any discounts or additional fees that may vary from purchase to purchase. This technique helps businesses accurately calculate the total costs associated with their investments and operations, ensuring financial stability. By understanding the full costs associated with a project, businesses are able to make more informed decisions that result in better outcomes overall.
