Calculate the direct materials price variance. (Do not round your intermediate calculations. Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (i.e., zero variance).) Price Variance b. Calculate the direct materials quantity variance. (Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (i.e., zero variance).) Quantity Variance c. Calculate the direct labor rate variance. (Do not round your intermediate calculations. Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (i.e., zero variance).) Rate Variance d. Calculate the direct labor efficiency variance. (Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (i.e., zero variance).) Efficiency Variance e. Calculate the variable overhead rate variance. (Do not round your intermediate calculations. Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (i.e., zero variance).) Rate Variance f. Calculate the variable overhead efficiency variance. (Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (i.e., zero variance).) Efficiency Variance g. Calculate the fixed overhead spending variance. (Indicate the effect of variance by selecting "Favorable", "Unfavorable", or "None" for no effect (.e., zero variance).) Spending Variance
