Calculation breakdown
- Market cap
- share price × total shares on issue
Worked example
A company trading at $12.00 with 500 million shares on issue has a market capitalisation of $6 billion, placing it in the mid-cap range.
Assumptions
- Size bands used (small under ~$2bn, mid ~$2–10bn, large above ~$10bn) are informal and vary between index providers.
- Market cap does not account for debt or cash; enterprise value is a fuller measure.
- Shares on issue should be sourced from the company's latest ASX announcement.
How this calculator works
Multiply a company's current share price by its total shares on issue to calculate market capitalisation, a common way to categorise companies as small-cap, mid-cap or large-cap on the ASX. Market cap is a quick sizing measure and does not account for debt or cash on the balance sheet.
Frequently asked questions
Where do I find shares on issue?
This is disclosed in a company's annual report, ASX announcements and most broker or market data platforms.
Is market cap the same as company value?
No, enterprise value also accounts for debt and cash and is often a more complete measure for comparing companies with different capital structures.
What are the ASX size bands roughly?
Common informal bands are small-cap under about $2 billion, mid-cap roughly $2–10 billion, and large-cap above $10 billion, though definitions vary by index provider.
