Formula and how it works
Example with real numbers
Here is the Customer Retention Value Calculator using the default values shown in the calculator above:
Inputs
| Customers | 1,000 |
|---|---|
| Monthly profit per customer ($) | 40 |
| Current monthly churn (%) | 4 |
| Improved churn (%) | 3 |
Results
| Extra lifetime profit | $333,333.33 |
|---|---|
| Current lifetime (months) | 25 |
| New lifetime (months) | 33.3 |
With these inputs the calculator returns Extra lifetime profit: $333,333.33. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Customers from 1,000 to 1,200 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Extra lifetime profit | $333,333.33 | $400,000.00 | +20% |
| Current lifetime (months) | 25 | 25 | 0% |
| New lifetime (months) | 33.3 | 33.3 | 0% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
