Conversion Rate Calculator
Conversion rate is the percentage of visitors who take the action you want — buy, sign up, book or enquire. Enter how many conversions you had and how many visitors you got, and this free calculator returns your conversion rate, and if you add a value per conversion, how much each visitor is worth and the total value generated.
What is a conversion rate?
A conversion rate is the share of people who completed a desired action out of everyone who had the chance to. If 240 people buy out of 8,000 visitors, your conversion rate is 3%. "Conversion" can mean a sale, a sign-up, a form submission, a booking — whatever the page is built to achieve.
It is the cleanest single measure of how well a page, ad or funnel turns attention into action, because it removes the effect of traffic volume: doubling visitors does not change the rate, only the count.
Conversion rate formula
Conversion rate (%) = conversions ÷ total visitors × 100
Value per visitor = total conversion value ÷ visitors
Value per visitor is one of the most useful figures in marketing: once you know what a visitor is worth, you know the maximum you can pay to acquire one and still profit.
A worked example
A landing page gets 8,000 visitors and produces 240 sales worth $50 each.
- Conversion rate: 240 ÷ 8,000 × 100 = 3%
- Total value: 240 × $50 = $12,000
- Value per visitor: $12,000 ÷ 8,000 = $1.50
That last number is the ceiling for your cost per click: pay less than $1.50 a visitor and the page is profitable; pay more and it is not.
What is a good conversion rate?
It varies widely by channel and intent. E-commerce often sits around 2–3%; lead-generation forms can run higher; cold display traffic far lower. Rather than chase a universal benchmark, track your own rate over time and test changes against it. A 1-point lift from 2% to 3% is a 50% increase in results from the same traffic — which is why conversion optimisation usually beats simply buying more visitors.
How to improve conversion rate
The reliable levers are clarity, friction and trust: a single obvious next step, fewer form fields and steps, faster pages, and visible proof that the offer is real. Speed of response matters too — leads that get an answer within minutes convert far better than those that wait hours, which is exactly the kind of instant, always-on follow-up an AI agent handles well.
Frequently asked questions
Is the conversion rate calculator free?
Yes, free and with no sign-up. It runs entirely in your browser and stores nothing.
How do I calculate conversion rate?
Divide the number of conversions by the number of visitors, then multiply by 100. 240 conversions from 8,000 visitors is a 3% conversion rate.
What counts as a conversion?
Any action the page is designed to produce — a purchase, sign-up, form submission, booking, download or call. You decide what counts; just be consistent so the rate is comparable over time.
What is value per visitor?
The average revenue each visitor generates, found by dividing total conversion value by visitors. It tells you the most you can afford to pay to acquire a visitor and still make money.
What is a good conversion rate?
It depends on the channel and intent. E-commerce often averages 2–3%, but the most useful comparison is your own rate over time. Improving it is usually cheaper than buying more traffic.
