What this calculator does

Conversion rate measures how often an opportunity turns into the desired action. Use it for website sessions, ecommerce orders, retail footfall, sales calls, leads, trials, demos, bookings, opt-ins or newsletter signups.

Formula used

Conversion rate equals conversions divided by visitors or opportunities, multiplied by 100. Target conversions equal visitors or opportunities multiplied by the target rate. Estimated value multiplies conversions by the average conversion value, and value per visitor divides that value by the original opportunity count.

How to read the result

Conversion rate is most useful when the numerator and denominator are clearly defined. A website conversion rate may use sessions or users, while a sales conversion rate may use leads, calls or qualified opportunities. A retail conversion rate may use store visits and purchases. Keep the same definition when comparing channels, stores or time periods.

Assumptions

  • Assumes every conversion has the same average value.
  • Does not include refunds, repeat orders, assisted conversions or attribution rules.
  • Works for any funnel where one action follows from a larger opportunity pool.
  • The visitors or opportunities input should match the same period as the conversions input.
  • Target uplift assumes the same opportunity count and does not model seasonality or traffic mix changes.

Frequently asked questions

How do you calculate conversion rate?

Divide conversions by visitors or opportunities, then multiply by 100. For example, 50 conversions from 2,000 visitors is a 2.5 percent conversion rate.

Can this work for website, retail and sales conversion rate?

Yes. Use the denominator that matches the funnel: website sessions, store visitors, leads, calls or opportunities. Then use completed orders, sales, bookings or signups as conversions.

Should I use sessions, users or clicks?

Use the denominator that matches your question. For ecommerce site performance, sessions may be useful. For sales outreach, opportunities or calls may be clearer.

How do I calculate the extra conversions needed for a target rate?

Multiply visitors or opportunities by the target rate, then subtract current conversions. For example, 10,000 visits at a 3.5 percent target needs 350 conversions.
