Market size variance
• Market size variance and market share variance
are two ways of using market data to determine
its effect on a company's profits. While the two
terms are related, they calculate the effects of
different changes.
• The market size variance can quantify the
effects of a change in market size on
profitability, assuming that the company's
market share stays the same. The formula for
calculating market size variance is:
Market size variance = ( Actual market size
– Expected market size) x Market share x
Profit margin per unit
