About Conversion Rate Calculator
The Conversion Rate Calculator turns raw traffic numbers into the metric that actually matters. Enter your visitors and conversions to instantly see your conversion rate as a percentage. Add optional revenue and cost figures and it also computes revenue per visitor, revenue per conversion, net profit, and ROI.
It's completely free with no sign-up, and it runs entirely in your browser. Nothing you type is uploaded or stored on a server, so you can plug in real campaign and sales data with confidence. Calculations update live as you type and gracefully handle blank or invalid inputs.
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.
- What counts as a good conversion rate?
- It varies by industry and channel, but many websites see 1-3% for general traffic, while 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 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. The tool also shows net profit, revenue per visitor, and revenue per conversion.
- 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 are always optional.
