AC SC = Standard variable overheads charged to production AC = Actual variable overheads incurred Variable overhead expenditure variance = BFVO – AVO BFVO = Budgeted flexed variable overheads AVO = Actual direct labour hours of input and the actual variable overhead costs incurred Variable overhead efficiency variance = (SH – AH) x SR SH = Standard hours of output AH = Actual hours of input SR = Standard overhead rate Fixed overhead expenditure variance = BFO – AFO BFO = Budgeted fixed overheads AFO = Actual fixed overhead spending Total sales margin variance = Actual sales revenue – Standard variable cost of sales – Budgeted contribution Sales margin price variance = (Actual selling price – Standard selling price) x Actual sales volume Fixed overhead rate per unit of output = Budgeted fixed overheads / Budgeted activity Budgeted fixed overheads Fixed overhead rate per standard hour of output = π΅π’ππππ‘ππ π π‘ππππππ βππ’ππ Total fixed overhead variance = Standard fixed overhead charged to production – Actual fixed overhead incurred Volume variance = (Standard hours for actual production – Budgeted hours for budgeted production) x Standard fixed overhead rate Volume efficiency variance = (Standard hours of output – Actual hours of input) x Standard fixed overhead rate Volume capacity variance = (Actual hours of input – Budgeted hours of input) x Standard fixed overhead rate Production volume ratio = Standard hours of actual output Production efficiency ratio = Capacity usage ratio = Budgeted hours of output Standard hours of actual output Actual hours worked Actual hours worked Budgeted hours of input Total materials cost variance = (actual production x standard material cost per unit of production) - actual materials cost Total labour cost variance = (actual production x standard labour cost per unit of production) - actual labour cost Fixed overhead volume variance = (Standard hours for actual production - budgeted hours for budgeted production) x standard fixed overhead rate Additional: Ending RE = Beg RE + Net income – Dividends Sales Volume Variance (where absorption costing is used) = (Actual Unit Sold – Budgeted Unit Sales) x Standard Profit Per Unit Sales Volume Variance (where marginal costing is used) = (Actual Unit Sold – Budgeted Unit Sales) x Standard Contribution Per Unit Direct material standard = standard quantity × standard prices Direct labour standards = standard quantity × standard prices Total actual cost = Qa x Pa Price variance = Flexible budget based on actual use = Usage variance = Total standard cost = Total materials variance = Symbols: a = Actual; s = Standard; Q = Quantity; P = Price Normal loss = Good ouput required / (1-Loss rate) Equivalent units (Weighted average) Equivalent units (FIFO) => Don’t forget to substract Opening work in process Equivalent cost per unit = Amount of (direct materials or conversion costs) / Equivalent units Budgeted profit : (i) add back adverse variances and to deduct favourable variances to actual profit to arrive at budgeted profit. And (ii) to avoid double counting : The fixed overhead volume variance = fixed overhead capacity variance + fixed overhead efficiency variance
