Formula and worked example

CALCULATION METHOD

Conversion rate = conversions ÷ visits × 100.

Example calculation

36 conversions from 1,200 visits equals a 3% conversion rate.

Try the same values in the calculator above. If your result differs, recheck the units, input order, assumptions and rounding displayed by the tool.

What your result means

Measure the share of visits that resulted in a defined conversion. Read the result label and unit carefully. A useful estimate describes only the inputs and assumptions supplied; it should not be treated as proof of a future outcome or a guarantee.

  • Check the displayed unit and period before comparing results.
  • Use values from a reliable source and keep them up to date.
  • Repeat the calculation with an independent check when the outcome matters.
