How to Use the Conversion Rate Calculator

Enter your total number of visitors and the number of conversions (signups, purchases, leads — whatever your goal is). The calculator instantly shows your conversion rate with a color-coded rating. Optionally enter your revenue per conversion to see the dollar impact of improvements. Use the "What If" slider to see how a 10%, 25%, or 50% improvement would affect your bottom line.

What Is Conversion Rate?

Conversion rate is the percentage of visitors who complete a desired action on your website. It's calculated by dividing the number of conversions by the total number of visitors, then multiplying by 100. For example, if 10,000 people visit your landing page and 250 sign up, your conversion rate is 2.5%. Conversion rate is one of the most important metrics in digital marketing because it directly measures how effectively your page turns visitors into customers. A small improvement in conversion rate can have a massive impact on revenue without spending more on traffic.

Frequently Asked Questions

What is a good conversion rate?+

There's no single good number. It depends on your industry, traffic source and what you're converting. For forms specifically, Zuko's 2025 benchmarks show 55% of people who view a form never submit it, and contact forms convert about 9% of the people who view them. The most useful benchmark is your own rate over time. See more in our form abandonment statistics guide.

How do I improve my conversion rate?+

The most impactful changes are: clearer value proposition, reducing form fields, adding social proof, improving page speed, and A/B testing your CTA copy and placement. Focus on one change at a time so you can measure what works.

Should I look at overall or per-page conversion rate?+

Both. Overall conversion rate gives you the big picture, but per-page rates show you which specific pages need work. Your homepage might convert at 1% while a targeted landing page converts at 8%.

How much traffic do I need for reliable conversion rate data?+

At minimum, you need around 100 conversions before drawing conclusions. With a 3% conversion rate, that means roughly 3,300 visitors. Use a sample size calculator for more precise guidance.
