Considering the swift growth of Warung Bakso Berkah Wonogiri, optimal management is crucial. This study aims to estimate future sales revenue at Warung Bakso Berkah Wonogiri 3 by comparing two methods: Monte Carlo and ARIMA. The prediction process will involve collecting historical data (such as sales from two years ago) and projecting it into the future using the Monte Carlo method and Autoregressive Integrated Moving Average (ARIMA). This research utilizes revenue data over a period of two years (January 2022 to December 2023), totaling 730 data points. Using the Monte Carlo method, revenue predictions are based on random numbers, while ARIMA predictions rely on the best predictive modeling process. The model produced by the Monte Carlo method has an error value of 0.07% or an accuracy of 99.93%, whereas the model generated using ARIMA has an error value of 0.03% or an accuracy of 99.97%. The process and results of this study are visualized through a graph for easier understanding and to illustrate annual comparisons..
