About the Conversion Rate Calculator
A conversion happens when a visitor does what you hoped they would: buys something, signs up, requests a quote, books a call, downloads a guide. The conversion rate is the share of visitors who do it. It is one of the most useful numbers in marketing, because it links the traffic you pay for to the results you actually get.
This conversion rate calculator works out your conversion rate from the number of visitors and conversions, and shows how many visitors it takes to produce one conversion. Add the average order value to see revenue and revenue per visitor. Enter a target rate, and it shows how many more conversions — and how much more revenue — that improvement would bring from the same traffic.
How to Use the Conversion Rate Calculator
Enter the number of visitors in the period. Use visitors or sessions, whichever your analytics reports, but use the same measure each time.
Enter the number of conversions in the same period.
Optionally, enter the average order value to see revenue per visitor.
Optionally, enter a target conversion rate to see what reaching it would be worth.
How Conversion Rate Is Calculated
conversion rate = conversions ÷ visitors
visitors per sale = visitors ÷ conversions
revenue = conversions × average order value
revenue per visitor = revenue ÷ visitors
target conversions = visitors × target rateStep-by-Step Example
12,000 visitors, 300 sales, an average order of 60 and a target of 3%.
Conversion rate: 300 ÷ 12,000 = 2.5%
Visitors per sale: 12,000 ÷ 300 = 40
Revenue: 300 × 60 = 18,000
Revenue per visitor: 18,000 ÷ 12,000 = 1.50
At 3%: 12,000 × 3% = 360 sales
Extra: 60 sales × 60 = 3,600Why Conversion Rate Matters So Much
There are two ways to get more sales from a website: bring in more visitors, or convert more of the visitors you already have. More traffic usually costs money, through advertising or content that takes time to build. A higher conversion rate costs nothing per visitor once the improvement is made, and it makes every future visitor more valuable too.
In the example, raising the rate from 2.5% to 3% is worth the same as a 20% rise in traffic. It also lowers the customer acquisition cost of every paid channel, because the same advertising spend now produces more customers.
What Is a Good Conversion Rate?
There is no single benchmark. Conversion rates depend on what is being asked of the visitor, the price, the industry and where the traffic comes from. A free newsletter sign-up can convert a large share of visitors; an expensive purchase converts far fewer. Visitors from a search for your brand name convert much better than visitors from a broad social media campaign.
The most useful comparison is with your own past performance, broken down by page, device and traffic source. That shows where you are improving and where visitors are dropping out.
Improving Your Conversion Rate
Make pages fast. Slow pages lose visitors before they have seen the offer.
Make the next step obvious. One clear call to action per page, visible without scrolling, works better than several competing ones.
Reduce friction. Ask for as little information as possible, offer guest checkout, and show delivery costs early.
Build trust. Reviews, guarantees, clear contact details and secure payment reassure visitors who have never bought from you.
Match the message. Visitors should land on a page that continues what the ad or search result promised.
Test changes one at a time, and give each test enough visitors to show a real difference rather than chance.
Measuring Conversions Accurately
Define the conversion clearly and count it the same way every time. Make sure tracking fires once per conversion, not on page refreshes, and that visitor counts exclude your own team and obvious bots. Small tracking errors can move a conversion rate more than real improvements do.
Micro-Conversions Along the Way
Most visitors do not buy on their first visit. Between arriving and converting there are smaller steps: viewing a product, adding it to the basket, starting the checkout, entering payment details. Measuring the conversion rate at each step — sometimes called a funnel — shows exactly where visitors drop out.
If many people add items to the basket but few complete the checkout, the problem is in the checkout: unexpected delivery costs, a forced account sign-up or a confusing form. If few people add anything to the basket, the product pages or the offer need work. Fixing the step with the biggest drop usually gives the largest gain.
Conversion Rate and Traffic Quality
A falling conversion rate is not always bad news. If a new campaign brings in many more visitors who are less ready to buy, the rate can fall while total sales rise. Always look at conversions and revenue alongside the rate, and compare rates within the same traffic source over time.
Understanding Your Result
Conversion rate is the share of visitors who converted.
Visitors per conversion shows how many visitors it takes to get one.
Revenue shows revenue and revenue per visitor, if you entered an order value.
At the target rate shows the conversions and extra revenue a higher rate would bring.
Worth knowing explains why the rate matters.
