The main purpose of this project was to understand whether e-commerce products were actually profitable after considering marketing costs. I worked with sales and product data from MySQL and combined it with product-level ad spend. I calculated True Net Profit, ROAS and Net Margin % and used these metrics to compare the performance of different products. I then created an Excel dashboard to present the results clearly and highlight products with strong profitability as well as products where advertising spend was reducing profits. Through this project, I learned that revenue alone does not show the complete picture of a product's performance.
