How large is a company, and how is that measured?

Market capitalisation

$225.00B

Share price multiplied by shares outstanding.

Size band

Mega cap

Bands are conventional size ranges, not a quality judgement.

How to read the result

  • Share price alone says nothing about size. A $20 share can belong to a far larger company than a $2,000 share.
  • Shares outstanding come from the company's own filings, so a buyback or a share issue changes the calculation.
  • Size bands describe scale, not quality. Large does not mean safe and small does not mean cheap.

What this calculator cannot tell you

  • Market cap ignores debt and cash; enterprise value exists for that reason.
  • The figure changes every time the share price moves.
  • Use the company's latest reported share count; an out-of-date count gives an out-of-date answer.
