How to Add a Grand Total in Tableau

Grand totals transform your data from individual data points into actionable business intelligence. You can instantly validate that your filtered views represent the complete picture, spot outliers by comparing individual values against the total, and present stakeholders with the bottom-line numbers they need for decisions. More importantly, grand totals serve as a built-in data quality check—when totals don't match your expectations, they reveal filtering issues, missing data, or calculation errors that might otherwise go unnoticed in complex dashboards.
