Bassic variances

Are these all correct statements regarding basic variance (chap 13 example 1)? 1) Budget cost is the total cost that we expect to happen and it is calculated as: Budget cost = Budgeted Production units x Standard rate $591600 = 8700 x $68 Is it correct that total budget cost is also called total standard cost (they mean same)? 2) Standard cost is the per-unit cost that we expect to happen which will be used to compare with actual results at the year-end and it is calculated as: Standard cost = Total Budgeted cost / Total Budgeted Production Standard cost = $591600 / 8700 Is it correct that standard cost per unit is also called standard cost per unit (they mean same)? 3) Actual cost is the total actual cost incurred at the year-end and it is calculated as: Actual cost = Actual Production units x Standard rate --605200----=-----------8900----------------x---------$68 4) In all the basic variances we compare the actual cost with standard cost with actual production to see the variance at the year-end. Actual costs-----------605200 Standard costs-------591600 Total variance--------$13600 Sorry to ask again but I was confused. Please don't mind :)
