Market share tells us how big a company’s slice of the pie is compared to all competitors. Think of it like a pizza party: if you eat 2 slices out of 10 total slices, you have 20 % of the pizza. In business terms, the formula is:
\$ \text{Market Share (\%)} = \frac{\text{Company's sales}}{\text{Total market sales}} \times 100 \$
Example: Company X sells 200 units in a market that sold 2 000 units.
\$ \frac{200}{2000} \times 100 = 10\% \$ – Company X owns 10 % of the market. 🍕
Market growth shows how fast the whole market is expanding or shrinking. It’s like watching a plant grow taller each year. The formula:
\$ \text{Market Growth (\%)} = \frac{\text{Current period size} - \text{Previous period size}}{\text{Previous period size}} \times 100 \$
Example: The market sold 1 800 units last year and 2 000 units this year.
\$ \frac{2000-1800}{1800} \times 100 \approx 11.1\% \$ growth. 📈
Imagine a football league where each team’s points are their sales.
If Team A has 30 points out of 300 total, they hold 10 % of the league’s points. If the league’s total points rise from 300 to 330, the league grew by 10 %. ⚽️
| Company | Sales (units) | Market Share (%) |
|---|---|---|
| Company X | 200 | 10.0 |
| Company Y | 500 | 25.0 |
Exam Tip: When asked to calculate market share, always express the answer as a percentage and round to one decimal place if required. For market growth, remember to use the previous period’s size in the denominator. Practice with quick mental math: if the market grows from 1 000 to 1 200 units, the growth is \$ \frac{200}{1000} \times 100 = 20\% \$. ✔️
Quick Check: If a company’s market share rises from 12 % to 15 % while the market size stays the same, what happened?
