Formula and how it works
Example with real numbers
Here is the Online Marketing Conversion Calculator using the default values shown in the calculator above:
Inputs
| Impressions | 500,000 |
|---|---|
| Clicks | 7,500 |
| Sales | 225 |
| Ad spend ($) | 6,000 |
| Average order value ($) | 70 |
Results
| Click-through rate | 1.5% |
|---|---|
| Conversion rate | 3% |
| Cost per click | $0.80 |
| Cost per acquisition | $26.67 |
| Return on ad spend | 2.63× |
With these inputs the calculator returns Click-through rate: 1.5%. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Impressions from 500,000 to 600,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Click-through rate | 1.5% | 1.25% | -16.7% |
| Conversion rate | 3% | 3% | 0% |
| Cost per click | $0.80 | $0.80 | 0% |
| Cost per acquisition | $26.67 | $26.67 | 0% |
| Return on ad spend | 2.63× | 2.63× | 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.
