How the click through rate calculator works
Click-through rate = clicks ÷ impressions × 100.
Check your measurements and assumptions
Platforms define impressions, viewability and invalid-click filtering differently. Compare rates from the same platform and reporting setup.
Review the estimate before you act
Compare this result with an independent measurement, supplier quote or institution guidance when the decision matters. Confirm that the units and assumptions match the labels above, and update the inputs when the conditions change. Keep a note of the values used so you can reproduce the estimate later. This calculator is a planning aid and does not replace professional, product-specific or local guidance.
How do I calculate click-through rate?
Divide the number of clicks by the number of impressions and multiply by 100.
