ii) Variance Analysis

Sales Variances

  • Sales Volume Variance

    (10,000−9,000)×Budgeted Contribution per Unit(10,000 – 9,000) \times \text{Budgeted Contribution per Unit} =(1,000)×(17.5−(8+3.5))= (1,000) \times (17.5 – (8 + 3.5)) =1,000×6=6,000 (Adverse)= 1,000 \times 6 = 6,000 \text{ (Adverse)}

  • Sales Price Variance

    (175,000÷10,000)−(162,000÷9,000)×9,000(175,000 ÷ 10,000) – (162,000 ÷ 9,000) \times 9,000 =(17.5−18)×9,000=4,500 (Favourable)= (17.5 – 18) \times 9,000 = 4,500 \text{ (Favourable)}

Material Variances

  • Total Variance

    72,000−64,380=7,620 (Favourable)72,000 – 64,380 = 7,620 \text{ (Favourable)}

  • Material Price Variance

    (0.80−0.87)×74,000(0.80 – 0.87) \times 74,000 =−0.07×74,000=5,180 (Adverse)= -0.07 \times 74,000 = 5,180 \text{ (Adverse)}

  • Material Usage Variance

    (90,000−74,000)×0.80(90,000 – 74,000) \times 0.80 =16,000×0.80=12,800 (Favourable)= 16,000 \times 0.80 = 12,800 \text{ (Favourable)}

Labour Variances

  • Total Labour Variance

    31,500−30,960=540 (Favourable)31,500 – 30,960 = 540 \text{ (Favourable)}

  • Labour Rate Variance

    (7.0−7.2)×4,300(7.0 – 7.2) \times 4,300 =−0.2×4,300=860 (Adverse)= -0.2 \times 4,300 = 860 \text{ (Adverse)}

  • Labour Efficiency Variance

    (4,500−4,300)×7(4,500 – 4,300) \times 7 =200×7=1,400 (Favourable)= 200 \times 7 = 1,400 \text{ (Favourable)}
