How to Calculate Conversion Rate: Formula, Examples & Website CVR
Conversion rate tells you what share of traffic completes a desired action. This guide covers the conversion rate formula, website and paid media calculations, worked examples, traffic and conversion forecasting, common denominator mistakes and practical interpretation.

Conversion rate is the percentage of traffic that completes a defined conversion action. Depending on the business, that action might be a purchase, qualified lead, form submission, quote request, booking, registration or another measurable outcome.
A 4% conversion rate means 4 conversions were generated for every 100 units of traffic measured in the denominator.
Traffic can mean ad clicks, sessions, users, visits or physical store visitors. Choose the metric that matches the decision you are evaluating and use it consistently.
Conversion rate formula
If 120 people convert from 4,000 website visits:
You can use the same formula for purchase rate, lead conversion rate, landing-page conversion rate, quote conversion rate or another conversion metric as long as the conversion and traffic counts use the same scope and reporting period.
How to calculate website conversion rate
Website conversion rate commonly uses sessions or visits as the denominator and completed website actions as the numerator.
3.00% CVR
4.00% CVR
2.50% CVR
If your analytics platform reports both users and sessions, decide which one your organization uses for the KPI. A sessions-based rate and a users-based rate are both valid calculations, but they are not numerically interchangeable.
How to calculate paid media conversion rate
Paid media teams often calculate click-to-conversion rate:
This is useful for Google Ads, Meta Ads and other acquisition channels when you want to understand how efficiently paid traffic turns into the selected conversion action.
Google Ads clicks, analytics sessions and CRM-qualified leads can all be part of the same funnel, but using them in one ratio without documenting the source can make comparisons difficult.

Conversion rate can also be used to work backwards or forecast a scenario.

Conversion rate can change when volume, audience quality, device mix, channel mix, offer or landing page changes.
What is a good conversion rate?
There is no single conversion-rate benchmark that is good for every campaign or website. The rate must be interpreted alongside the conversion definition, traffic intent, economics and business goal.
A campaign generating fewer but highly qualified leads can be more valuable than a campaign with a higher conversion rate built around a low-friction, low-value action.
CPA, ROAS, AOV, qualified lead rate, close rate and revenue help determine whether a conversion-rate improvement actually improved the business outcome.
Conversion rate vs click-through rate
Measures the transition from ad exposure to click.
Measures the transition from traffic to conversion.
CTR can indicate whether an ad attracts clicks. Conversion rate indicates whether the resulting traffic completes the desired action. They should not be treated as interchangeable metrics.
Common conversion rate calculation mistakes
- Mixing denominators.Comparing a clicks-based CVR with a sessions-based CVR as though they are identical.
- Using mismatched date ranges.Conversions and traffic must come from comparable reporting periods.
- Changing the conversion definition.A purchase conversion rate cannot be compared directly with a sign-up conversion rate without context.
- Ignoring conversion quality.A higher rate does not automatically mean stronger profitability or lead quality.
- Overreacting to tiny samples.One conversion from ten visits produces a 10% rate, but that is not necessarily a stable benchmark.
Conversion rate FAQs
How do you find conversion rate?
Divide conversions by traffic, then multiply by 100.
Can conversion rate use clicks?
Yes. Conversions ÷ clicks × 100 gives a click-to-conversion rate.
Can conversion rate use website visits?
Yes. Use conversions and visits from the same reporting period.
Is CVR the same as CTR?
No. CTR measures clicks from impressions; CVR measures conversions from traffic.
