Show the math

Conversion rate is conversions over visitors; add revenue to see value per visit:

rate = conversions ÷ visitors × 100

z = (p₂ − p₁) ÷ √(p̂(1 − p̂)(1/n₁ + 1/n₂))

Revenue per visitor (RPV) is often a better optimisation target than rate alone, since it accounts for order value. The A/B test uses a pooled two-proportion z-test; treat p < 0.05 (95% confidence) as significant. All math runs in your browser.

What this does

A conversion rate calculator turns conversions and visitors into a conversion rate, and adds revenue to show value per visitor and per conversion.

How to use it

  1. Enter the visitors.
  2. Enter the conversions.
  3. Add revenue if you have it.
  4. Read the rate and value per visitor.

How it works

Revenue per visitor captures both conversion rate and order value, so it is often a better optimisation target than rate alone.

conversion rate = conversions ÷ visitors × 100

Understanding your result

The conversion rate is the share of visitors who act, but revenue per visitor is often the better target because it captures both the rate and the order value. A rising rate with flat revenue per visitor can mean you are winning low-value visits, so track the two together.

Example

50 conversions from 2,000 visitors is a 2.5% rate.

Frequently asked questions

How do I calculate conversion rate?

Divide conversions by visitors and multiply by 100 to get the percentage.

Why look at revenue per visitor?

Revenue per visitor captures both conversion rate and order value, so it is often a better optimisation target than rate alone.
