The percent of actual revenue compared to budgeted or forecast revenue; when measuring multiple periods (typically months) Mean Absolute Percent Error (MAPE) should be factored to most accurately calculate Forecast Accuracy (e.g., if the absolute variance for January is 8.0 and the absolute variance for February is 6.0, the MAPE for those two months would be 7.0); Divide Actualized Revenue by Forecasted Revenue
