The budgeted income statement is the best tool for evaluating an organization's performance. It includes projected revenues and expenses, which are key indicators of financial performance. This comprehensive overview allows for comparison between actual performance and budgeted expectations, effectively highlighting variances and areas needing improvement. Other budgets like the cash budget, budgeted balance sheet, and selling and administrative expense budget focus on specific areas and are helpful for detailed analysis, but they do not provide the overarching view of financial performance like the budgeted income statement does.
