About Conversion Rate Calculator
The Conversion Rate Calculator turns raw traffic numbers into the marketing metric that actually matters: the percentage of visitors who take the action you care about. Enter your total visitors and conversions and it instantly returns your conversion rate as a percentage, so you can measure a landing page, an ad campaign, an email blast, or a full sales funnel without wrestling with a spreadsheet formula.
Add optional revenue and cost figures and it goes further, computing revenue per visitor, revenue per conversion, net profit, and ROI on the same screen. That makes it as useful for sales teams sizing up close rates as it is for marketers benchmarking pages over time. This is a marketing and sales conversion-rate tool, not a currency or exchange-rate converter, so the inputs are the people and dollars you already track, and the output tells you how hard your traffic is working.
Everything is completely free with no sign-up and no usage limits, and it runs entirely in your browser. Calculations update live as you type, and blank or invalid inputs are handled gracefully instead of throwing errors. Because nothing is uploaded or stored on a server, you can plug in real campaign spend, sales numbers, and revenue with confidence that your data never leaves your device.
Frequently asked questions
- How is conversion rate calculated?
- Conversion rate is your number of conversions divided by your number of visitors, multiplied by 100 to express it as a percentage. For example, 125 conversions from 5,000 visitors is a 2.5% conversion rate. The calculator does this the moment you enter both numbers.
- How do I calculate a sales conversion rate?
- Divide the number of sales or won deals by the total leads or visitors you started with, then multiply by 100. Enter those two figures as conversions and visitors and the tool returns your sales conversion rate instantly, plus revenue per conversion if you add your revenue.
- Can I use this for marketing campaigns and landing pages?
- Yes. Plug in the visitors a landing page, ad, or email received and how many converted, and you'll see the conversion rate for that specific campaign. Adding cost and revenue also shows ROI, so you can compare which marketing channels actually pay off.
- What counts as a good conversion rate?
- It varies by industry and channel, but many websites see 1-3% for general traffic, while focused landing pages and paid campaigns often aim for 5-10% or higher. Use the calculator to benchmark your own pages over time rather than chasing a single universal number.
- How do you calculate ROI here?
- When you enter both revenue and cost, ROI is calculated as (revenue minus cost) divided by cost, times 100. It shows the percentage return on every dollar of spend, and the tool also displays net profit, revenue per visitor, and revenue per conversion.
- What does the calculator show besides conversion rate?
- With optional revenue and cost added, it also returns revenue per visitor, revenue per conversion, net profit, and ROI. That lets you see not just how many people convert, but how much each visitor and each conversion is actually worth.
- Does this convert currency or exchange rates?
- No. This measures your marketing and sales conversion rate, the share of visitors who convert, not currency exchange rates. If you're trying to convert dollars to euros or check a money exchange rate, you'll need a dedicated currency converter instead.
- Can it convert units like flow rate or spring rate?
- No. It handles conversion rate as a marketing and sales percentage, not engineering unit conversions such as flow rate, volumetric flow rate, or spring rate. For those, use a dedicated unit rate converter.
- Is this conversion rate calculator free?
- Yes, it is completely free to use with no account, sign-up, or usage limits. You can run as many calculations as you like.
- Is my data uploaded or stored anywhere?
- No. All calculations happen locally in your browser using JavaScript. Your visitor counts, revenue, and cost figures are never sent to a server, saved, or shared, so your data stays private.
- What if I enter zero visitors or leave a field blank?
- The tool handles this gracefully. It won't divide by zero or show errors like NaN. If visitors is zero or a required field is empty, it prompts you for valid input instead of crashing, and revenue and cost always stay optional.
