hi john
how do you calculate market size & market share for variance
January 27, 2018 at 6:36 pm #433463there is question from December 2007 where you should analyse the total sales volume variance into components for market size & market share
budget volume 180,000 units sales price $17 standard contribution $7
actual volume 176,000 units sales price 16.40
total market for diaries is estimated in budget 1.8m units
actual total market shrank 1.6m units period under reviewJanuary 28, 2018 at 10:27 am #433580I assume that the question actually says that the actual total market shrank to 1.6M
The budget assumed a 10% market share (180,000 / 1.8M)
Since the actual total market was only 1.6M, then a 10% market share would be only 160,000.
Therefore the change in volume due to market size would be 180,000 – 160,000 = 20,000 units (adverse).
Given they would then have expected to sell 160,000 units but they actually sold 176,000, the extra 16,000 units (favourable) are due to a change in market share.
In both cases the units would be costed at standard contribution of $7 per unit as usual.

market share is 180,000-160,000 (180,000/1,800,000*1,6000,000)x7=140,000( A)
market size 160,000-176,000*7=112000(F)
it almost like planning & operational variance
