What this calculator tells you

Conversion rate turns traffic into a measurable sales system. It helps separate a traffic problem from an offer or checkout problem.

Conversion rate = orders / sessions × 100. Additional sessions = target orders gap / current conversion rate.

When to use it

Use it after a traffic campaign, a site redesign, or a checkout change to estimate the sales impact.

Use conservative inputs

Start with your landed cost, real fee rates, and a pessimistic advertising cost. The result is more useful when the assumptions are honest.

Watch the common mistake

Comparing conversion rates across traffic sources without separating new visitors, returning visitors, and high-intent search traffic.

Frequently asked questions

What counts as a session?

A session is typically a visit that may include multiple page views. Check your analytics platform's definition before comparing numbers.

What is a good conversion rate?

It varies by traffic source, price, and product. Compare against your own baseline and similar traffic segments first.

Should I include repeat purchases?

For a blended site metric, yes. For campaign diagnosis, separate new-customer and returning-customer conversion.
