This free conversion rate calculator tool works for websites, ecommerce stores, marketing campaigns, and sales funnels.
Running a website, a marketing campaign, or an online store — but not sure if it's actually performing? Conversion rate tells you exactly that. This calculator measures three things — your website performance, your sales effectiveness, and your marketing campaign results. Enter your visitors, conversions, ad spend, and average order value — instantly see your conversion rate, cost per conversion, total revenue, and revenue per visitor. Numbers that used to take spreadsheets now take seconds.
Conversion rate is simply this — out of all the visitors who came to your website or platform, how many actually did something useful for your business? That could be making a purchase, filling a form, signing up, or any action that benefits you. For example — 1000 visitors came to your site and 50 made a purchase. Your conversion rate is 5%. The other 950 left without doing anything. Knowing this number tells you exactly how well your website or campaign is actually working.
The formula is always the same — conversions divided by total visitors, multiplied by 100. A 5% conversion rate means that 5 out of every 100 visitors take the desired action. The other 95 leave without converting. Understanding this ratio — and what it costs to acquire each conversion — is the foundation of any serious analysis of marketing efficiency.
The standard formula used in every conversion rate calculator is:
:contentReference[oaicite:0]0This formula works for website traffic, marketing campaigns, sales funnels, and lead generation. Simply divide total conversions by total visitors and multiply by 100 to get the percentage.
Out of every 100 visitors, how many actually converted — that's your conversion rate. If 5 out of 100 visitors made a purchase, your conversion rate is 5%. Simple percentage that tells you how well your website or campaign is performing.
The count of visitors who left without doing anything useful. For example — 1000 visitors came, 50 converted, so 950 are non-conversions. These 950 people visited your platform but gave you no benefit. This number helps you understand how many potential customers you're losing.
Shows how many visitors it takes to get one conversion. For example 1:20 means out of every 20 visitors, only 1 converted. Lower the second number, better your conversion performance.
How much did each conversion actually cost you? For example — you spent ₹1000 on ads and 5 people converted. Your cost per conversion is ₹200. This tells you whether your ad spend is worth it or not.
Total money earned from all conversions. For example — your site sells a course for ₹100. 100 visitors came, 10 purchased. Total revenue = 10 × ₹100 = ₹1,000. Simple — conversions multiplied by your average order value.
Total revenue divided equally across all visitors — converters and non-converters both. For example — 100 visitors came and total revenue was ₹1,000. Revenue per visitor = ₹10. This tells you the average value of every single visitor to your platform.

The honest answer is that it depends entirely on the context — the industry, the traffic source, the type of conversion, and the price point of what is being sold. A rate that would be excellent for a high-ticket product might indicate poor performance for a low-friction lead generation form.
E-commerce (physical products)
Typically 1 to 4%. Stores selling products above $200 often see lower rates because purchase decisions take longer. Flash sale pages and heavily discounted offers can spike to 8 to 15% because urgency and price sensitivity work together.
B2B SaaS (free trial or demo request)
Typically 1 to 5%, with significant variation based on how much information is required and how qualified the traffic is. Highly targeted paid traffic converts at the upper end; broad awareness campaigns at the lower end.
Email marketing campaigns
Sent to engaged subscriber lists, often produce conversion rates of 2 to 5% on a specific offer — significantly higher than cold traffic from ads because the relationship and trust are already established.
Lead generation pages
B2B lead generation pages typically see 1 to 3%. The more information required in the form, the lower the rate. Pages requesting only a name and email outperform pages with five or more fields by a significant margin.
The more useful question is not "is my conversion rate good?" but "is my revenue per visitor growing?" A higher conversion rate on a lower order value can produce lower revenue per visitor than a lower conversion rate on a higher order value. Revenue per visitor accounts for both dimensions simultaneously.
Evaluating a paid campaign
Enter total clicks or sessions as visitors, purchases or leads as conversions, total ad spend, and average order value. The outputs tell you your conversion rate, cost per conversion, and whether the revenue generated justifies the spend.
Comparing landing pages
Run the calculator for each page variant. A page with a 3% rate driving $1.20 revenue per visitor outperforms a page with 4% driving $0.90 — because the first page's visitors convert to higher-value purchases.
Setting traffic targets
If you know your revenue per visitor and monthly revenue target, work backward to the traffic volume you need. A revenue per visitor of $0.80 and a $40,000 monthly target requires 50,000 visitors per month.
Modelling conversion rate improvements
Increasing conversion rate from 2% to 3% on 10,000 monthly visitors means 100 additional conversions. At an average order value of $75, that is $7,500 in additional monthly revenue — from the same traffic.
Align the landing page with the traffic source
Visitors who click an ad for a specific product and land on a generic homepage experience a disconnect that kills conversions. Every traffic source should land on a page that directly continues the promise made in the ad, email, or link.
Reduce friction at the conversion point
Every unnecessary field in a form, every extra step in a checkout, and every piece of information a visitor has to hunt for reduces conversions. Streamlining the path from arrival to conversion is consistently one of the highest-return optimisation moves.
Test one variable at a time
Headline, hero image, call-to-action text, button colour, form length, social proof placement — all of these affect conversion rate. Testing multiple changes simultaneously makes it impossible to know which change drove the improvement.
Measure revenue per visitor, not just conversion rate
Conversion rate alone does not tell the full story. A change that increases conversion rate but reduces average order value may actually hurt the business. Revenue per visitor accounts for both dimensions and gives a cleaner signal.
Three things this calculator tells you that most businesses don't track properly. First — your actual conversion rate. Not a guess, not a feeling — exact percentage of visitors who took action. Second — your cost per conversion. If you're spending ₹1,000 on ads and getting 5 conversions, each conversion costs ₹200. Is that worth it? This calculator tells you instantly. Third — revenue per visitor. Every visitor to your site has an average value. Know that number and you know exactly how much you can afford to spend on traffic. Enter your numbers, get your complete report in seconds.

Simple example — if your website gets 1000 visitors and 50 people make a purchase, your conversion rate is 5%. This calculator goes further — enter your total ad spend and average order value along with visitors and conversions, and instantly get a complete report showing conversion rate, cost per conversion, total revenue, and revenue per visitor.
Enter four things — total visitors, total conversions, total ad spend, and average order value. The calculator instantly shows your conversion rate percentage, cost per conversion, revenue per visitor, total revenue, and count of non-conversions. Everything in one report, no manual calculation needed.
It depends on the type of website and industry — but generally 5% to 10% conversion rate is considered good. Below 1-2% means your traffic is not converting well and something needs to be fixed — either the traffic quality, the landing page, or the offer itself.
Conversion rate tells you how many visitors are actually interested in what you're offering, whether you're making profit or loss, and whether your current strategy is working or needs to change. It's the clearest signal of how your website or campaign is really performing — not just how much traffic you're getting.
