What is the Market Capitalization Calculator?
Compute market cap and classify the company by size. To use the Market Capitalization Calculator, enter share price, shares outstanding; it returns market capitalization, and shows them instantly as you type.
Where the Market Capitalization Calculator fits
Compute market cap and classify the company by size. The main figure it returns is the Market capitalization, worked out from the values you enter.
It belongs with the other stocks & equity analysis tools. If you are comparing options or checking a result from another angle, try the Enterprise Value Calculator, Free Float Calculator or the EBITDA Multiple Calculator.
How to use the Market Capitalization Calculator
- Enter your numbers. Start with Share price ($), Shares outstanding. Take price and share figures from the latest filing or quote. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Market capitalization. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Market Capitalization Calculator using the default values shown in the calculator above:
Inputs
| Share price ($) | 82 |
|---|---|
| Shares outstanding | 45,000,000 |
Results
| Market capitalization | $3,690,000,000.00 |
|---|
With these inputs the calculator returns Market capitalization: $3,690,000,000.00. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Share price ($) from 82 to 98.4 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Market capitalization | $3,690,000,000.00 | $4,428,000,000.00 | +20% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
Method and limits. This calculator applies the formula in the section above to your inputs, in your browser; nothing you enter is stored on our servers. The result is only as accurate as the numbers you enter and the formula shown above. It is for information, not financial, tax or legal advice.

Company filings (10-K and 10-Q), investor relations pages and your broker show earnings, equity, debt and share counts.
