For “Budget variance (%)”, the trend is good when:

For budget variance, “good” performance is generally defined as being within an acceptable tolerance range around zero variance. The direction (increasing vs decreasing) can be misleading because variance can be positive or negative depending on whether actuals are above or below budget, and whether the budget line is cost or revenue. Therefore, evaluating the trend as “good when within range” is the most robust interpretation. This aligns with best practice: define a target (often 0%) and set tolerance bands (e.g., green within ±3%, yellow slightly outside, red beyond). A key measurement challenge is that variance can look “better” simply due to timing (accruals, delayed invoices) rather than real performance. To address this, KPI governance often includes consistent cut-off rules and commentary requirements explaining major drivers of variance. Also, organizations may track separate KPIs for cost variance and revenue variance because “favorable” direction differs. Using “within range” avoids confusion and focuses discussions on whether performance is acceptably controlled rather than chasing directionality that may not represent improvement.
