The revenue variance for an accounting period is the difference between budgeted and actual revenue. A favorable revenue variance occurs when actual revenues exceed budgeted revenues, while the opposite is true for an unfavorable variance.

A variance is the difference between the budgeted figure (or flexed budget figure) and the actual figure. A variance may refer to patient days (volume), dollars (price), or FTEs (volume). A variance may be considered favorable or unfavorable.xample: If your unit was budgeted for 500 patient days for one month and the actual patient days were 525, then your unit experienced a favorable patient day variance of 25. However, if your unit was budgeted for 20 FTEs and the actual FTEs paid were 21.5 then your unit experienced an unfavorable FTE variance of 1.5.
