Accurate Cost of Goods Manufactured (COGM) determination is crucial for MSMEs to maintain profitability. This study compares COGM and profit per unit between traditional and Activity-Based Costing (ABC) methods at Roti Kirana. A descriptive quantitative approach was used by analyzing production cost data, cost driver rates, and overhead allocation. The traditional method yields a unit COGM of IDR 49,476 and profit of IDR 38,024. The ABC method yields a unit COGM of IDR 49,047 and profit of IDR 38,453. A COGM variance of IDR 429 exists due to overhead allocation distortions. Although ABC is more precise, Roti Kirana is advised to adhere to the traditional method due to its micro-scale operations and simple production process. Transitioning to ABC is recommended as overhead cost complexity grows in the future.
