Calculate conversion rate from visitors and conversions — or reverse it to forecast required traffic or expected conversions based on a target rate.

Formula Conversion Rate = (Conversions ÷ Visitors) × 100

Measuring one landing page rather than a whole site, campaign or channel? The landing page calculator also shows how many visitors it takes to get one conversion. Landing Page Conversion Rate Calculator.

How to use this calculator

Enter the total number of visitors and the number who converted. The calculator returns your conversion rate as a percentage. Use the "Calculate" selector to solve instead for required traffic (given a target rate and conversion goal) or expected conversions (given known traffic and a rate).

What is Conversion Rate?

Conversion rate is the percentage of visitors who complete a desired action — a purchase, signup, form submission, download, or any other goal you've defined. It's one of the most important metrics in digital marketing because it measures how effectively your traffic turns into outcomes. A conversion rate of 2% means 2 out of every 100 visitors convert. Small improvements in conversion rate compound dramatically: doubling your rate effectively doubles your revenue from the same traffic, without spending more on acquisition.

  • Comparing conversion rates across channels, campaigns, and audiences
  • Forecasting required traffic to hit a conversion goal
  • A/B testing and optimization work
  • Reporting performance to clients or stakeholders
  • Diagnosing funnel drop-off

Frequently asked questions

What is a good conversion rate?
It depends heavily on industry, channel, and what counts as a conversion. Ecommerce conversion rates typically average 2–3%; SaaS free-trial conversion rates often land at 2–5%; lead gen landing page conversion rates can range from 5–15% depending on offer and quality; B2B demo request forms often convert at 1–3%. Compare against your own historical performance and segment benchmarks rather than a universal number.

How is conversion rate calculated?
Conversion Rate = (Conversions ÷ Total Visitors) × 100. If 250 out of 10,000 visitors convert, your conversion rate is 2.50%.

What counts as a conversion?
Whatever goal you've defined — a purchase, signup, form submission, demo request, newsletter subscription, download, or any meaningful action. Consistency matters: pick a clear definition and apply it uniformly across reporting periods so comparisons are meaningful.

Should I measure conversion rate per session or per visitor?
Both are valid; pick one and be consistent. Session-based conversion rate (conversions ÷ sessions) is more common in analytics tools because sessions are easier to track. Visitor-based rate (conversions ÷ unique visitors) can be more accurate for measuring how well you convert new audiences, especially if a single person visits multiple times before converting.

How do I improve my conversion rate?
High-leverage improvements typically come from clearer value propositions, faster page load times, stronger and more specific calls-to-action, reduced form friction, trust signals (reviews, security badges, social proof), mobile optimization, and A/B testing your hero section and CTAs. Small changes to the highest-traffic pages usually outperform large changes to low-traffic ones.

What's the difference between conversion rate and click-through rate?
Click-through rate (CTR) measures how often people click a link or ad (clicks ÷ impressions). Conversion rate measures how often those clicks complete a desired action (conversions ÷ visitors or sessions). CTR is about attracting attention; conversion rate is about converting that attention into outcomes.

Is a higher conversion rate always better?
Not necessarily. A very high conversion rate can indicate you're only attracting highly qualified traffic — which might mean you're not reaching enough people. Scaling acquisition often lowers conversion rate (because top-of-funnel audiences are less qualified) while increasing total revenue. Evaluate conversion rate alongside traffic volume and total conversions.
