Conversion Rate Calculator.
45 enquiries from 1,500 website visitors is a 3 percent conversion rate; lifting it to 4 percent would bring 15 more enquiries from the same traffic. Enter your visitors and conversions, and optionally an average order value and a target rate, to see your rate, revenue per visitor and what improvement is worth.
Use the same date range and the same definition of a visitor (users, sessions or ad clicks) for both numbers. Nothing is sent to a server.

What you'll get.
A real example of what this tool produces. Run it above with your own inputs.
A conversion rate is the share of visitors who do the thing you want: buy, book, call, fill in a form or sign up. It is calculated as conversions divided by visitors, times 100. For a small business website it is the single most useful number in your analytics, because it tells you whether the traffic you already have is turning into customers, which is usually cheaper to fix than buying more traffic.
Enter visitors and conversions from Google Analytics, your ad platform or your shop dashboard. Add the average value of a conversion to see revenue per visitor, add your spend to see cost per conversion, and set a target rate to see how many extra sales or leads an improvement would bring. Results update in your currency.
The tool is free and runs in your browser. It is built by Neweb, the AI website builder for small businesses (free plan, paid plans from $9/month billed yearly, $19 month-to-month), whose generated sites put a clear call to action, tap-to-call phone number and contact form on every page because those are what move this number.
How to use the conversion rate calculator
Enter your visitors (users, sessions or ad clicks) and your conversions for the same period.
Optionally add the average value of a conversion, such as average order value or the typical value of a lead that becomes a job.
Optionally add a target rate to see the extra conversions and revenue it would bring, and your traffic or ad spend to see cost per conversion.
Click Calculate to see the conversion rate, visitors per conversion, revenue per visitor and the improvement scenario.
Repeat for individual pages or campaigns to find the ones that convert worst; they are the best place to start.
Why this matters for your business
It is the cheapest growth lever. Doubling traffic usually means doubling ad spend or months of SEO. Lifting a conversion rate from 2 to 3 percent brings 50 percent more customers from the traffic you already pay for.
It tells you where the problem is. High traffic with a low rate points at the website: slow pages, a weak offer or a hidden contact button. Low traffic with a good rate points at visibility. Each needs a different fix.
It makes marketing spend comparable. Cost per conversion lets you compare a Google Ads campaign, a social campaign and a directory listing on the same basis.
Tips for better results
- Make sure every visitor can contact you in one tap: a click-to-call number, a WhatsApp or SMS link and a short form above the fold on mobile.
- Speed matters: test key pages with the website speed test and compress heavy images.
- Tag campaign links with the UTM builder so you can calculate a conversion rate per channel, not just for the whole site.
- Compare like with like: a product page and a blog post serve different intents and convert at very different rates.
- Change one thing at a time, such as the headline, the button text or the form length, and measure for a few weeks before judging.
- Treat published "average conversion rates" with caution; they vary by industry, traffic source and how a conversion is defined.
Example
A real-world walkthrough
A dog groomer in Austin gets 1,500 website visitors in October and 45 booking requests. The calculator shows a 3 percent conversion rate, one booking for every 33 visitors. Her average booking is worth $120, so revenue per visitor is $3.60.
She sets a target of 4 percent. The same traffic would produce 60 bookings, 15 more, worth an extra $1,800 a month. She moves the booking button above the fold, adds a text-message link and shortens the form from nine fields to four, then re-runs the numbers at the end of November.
Frequently asked questions
How do you calculate a conversion rate?
Divide the number of conversions by the number of visitors in the same period and multiply by 100. For example, 45 enquiries from 1,500 visitors is 45 ÷ 1,500 × 100 = 3 percent. Decide up front whether "visitors" means users, sessions or ad clicks, and use the same definition every time so the rate is comparable month to month.
What is a good conversion rate for a small business website?
There is no universal figure. Published benchmarks for e-commerce and lead-generation sites commonly fall somewhere between 1 and 5 percent, but they vary widely by industry, traffic source, price and how a conversion is defined. A local emergency service may convert far higher than an online store selling expensive furniture. The most useful benchmark is your own rate last quarter: aim to beat it.
What counts as a conversion?
Any action that moves a visitor toward becoming a customer and that you can count: a purchase, a booking, a form submission, a phone call from the website, a WhatsApp message, a quote request or a newsletter sign-up. Track your main conversion separately from smaller ones; a site with many sign-ups but few sales has a different problem from one with few of either.
How can I improve my website conversion rate?
Start with the basics: a clear headline that says what you do and where, one obvious call to action per page, a phone number and contact options visible on mobile, fast loading, real photos, prices or price ranges where possible, and reviews. Remove friction from forms. Then test changes one at a time. Builders such as Neweb generate these elements by default, but every business still needs to check them on a phone.
Should I use users or sessions in the calculation?
Either works if you are consistent. Users give a rate per person, which suits considered purchases that take several visits; sessions give a rate per visit, which suits impulse purchases and campaign landing pages. For paid ads, clicks are the natural denominator. Google Analytics 4 reports both users and sessions, so pick one and note it next to the figure.
