Formula and how it works
Example with real numbers
Here is the Price to Book Ratio Calculator using the default values shown in the calculator above:
Inputs
| Share price ($) | 38 |
|---|---|
| Book value per share ($) | 22 |
Results
| P/B ratio | 1.73× |
|---|
With these inputs the calculator returns P/B ratio: 1.73×. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Share price ($) from 38 to 45.6 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| P/B ratio | 1.73× | 2.07× | +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.
