Boston Frame, Inc., produces several different styles and sizes of picture frames. The following activity describes Boston Frame's overhead costs during March: (Click on the icon to view the overhead costs.) Read the requirements. . . . . . Requirement 1. Calculate the variable overhead rate and efficiency variances for the month of March. (Enter the variances as positive numbers. Enter the currency amounts in the formulas to the nearest cent, then round the final variance amounts to the nearest whole dollar. Label the variance as favorable (F) or unfavorable (U).) Begin by computing the variable manufacturing overhead rate variance. First determine the formula for the rate variance, then compute the rate variance for variable manufacturing overhead. Variable overhead rate variance Now compute the variable manufacturing overhead efficiency variance. First determine the formula for the efficiency variance, then compute the efficiency variance for variable manufacturing overhead. Variable overhead E efficiency varianceRequirement 2. Calculate the fixed overhead budget and volume variances for the month of March. (Enter the variances as positive numbers. Label the variance as favorable (F) or unfavorable (U).) Begin by computing the fixed manufacturing overhead budget variance. First determine the formula for the budget variance, then compute the budget variance for fixed manufacturing overhead. Fixed MOH = budget variance Now compute the fixed manufacturing overhead volume variance. First determine the formula for the volume variance, then compute the volume variance for fixed manufacturing overhead. Fixed MOH volume variance Requirement 3. Calculate the total fixed overhead variance for the month of March. (Enter the variances as positive numbers. Label the variance as favorable (F) or unfavorable (U).) First determine the formula for the budget variance, then compute the total fixed overhead variance.
