Power BI Time Intelligence Dashboard

Retail Sales Analytics with Advanced DAX

Comprehensive Power BI dashboard analyzing 4 years of retail sales data (80K+ records, 2022–2025) with advanced DAX time intelligence capabilities. Implements sophisticated time-based calculations including Year-over-Year growth analysis, Month-over-Month changes, Year-To-Date (YTD) metrics, Quarter-To-Date (QTD) performance, and Month-To-Date (MTD) tracking. Features multi-dimensional analysis across channels (Marketplace, Online, Retail, Wholesale), product categories (Electronics, Furniture, Fashion, etc.), and geographic regions (North, South, East, West). Interactive drill-down capabilities enable executive-level insights from high-level KPIs to granular monthly comparisons. Includes budget variance analysis, forecasting trends, regional performance heatmaps, and top-category growth rankings. Built with enterprise-grade data modeling and optimized DAX formulas for real-time performance monitoring.
