How the conversion rate calculator works
Conversion rate = completed conversions ÷ visitors or sessions × 100.
Check your measurements and assumptions
Use a consistent denominator such as sessions or unique visitors. Analytics tools may define and deduplicate these differently; this calculator does not assess attribution.
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 conversion rate?
Divide completed goals by the selected visitor or session count and multiply by 100.
