Free Conversion Rate Calculator

Calculate your conversion rate by dividing conversions by total visitors to measure how effectively your pages and campaigns convert traffic.

What is Conversion Rate?

Conversion Rate (CR) is the percentage of visitors who complete a desired action, like making a purchase or filling out a form. It's calculated by dividing conversions by total visitors.

Why it matters: Improving conversion rate is the most cost-effective way to grow revenue. Doubling your conversion rate has the same effect as doubling your traffic, but without additional ad spend.

Formulas:

  • Required Visitors = (Conversions ÷ Target Rate) × 100
  • Expected Conversions = (Visitors × Target Rate) ÷ 100

Conversion rate depends on how you define a "conversion" (purchase, lead, signup). Ensure consistent definitions when comparing rates across campaigns.

What Is Conversion Rate?

Conversion rate is the percentage of visitors who complete a desired action — a purchase, signup, lead form submission, or any goal you define. It's the bridge between traffic and revenue.


A high conversion rate means your landing pages, offer, and user experience effectively persuade visitors to take action. It directly impacts CPA: double your conversion rate and you halve your cost per acquisition.


Track conversion rate at every level: ad → click (CTR), click → landing page (bounce rate), landing page → conversion (conversion rate). Each step reveals optimization opportunities.

Conversion Rate Formula

Conversion Rate = (Conversions ÷ Total Visitors) × 100. 50 sales from 2,000 visitors = 2.5% conversion rate.


Be precise about your denominator. "Visitors" can mean unique users, sessions, or page views — each gives a different rate. Sessions is the most common standard for e-commerce.


Segment conversion rate by traffic source. Paid search might convert at 4% while social media converts at 1%. This tells you which channels bring the most qualified traffic, not just the most traffic.

Conversion Rate Benchmarks

E-commerce overall: 2-3%. Fashion: 1.5-2.5%. Electronics: 1-2%. Food & beverage: 3-5%. Health & beauty: 2-4%. B2B SaaS free trial: 5-15%. B2B lead generation: 2-5%.


Top 10% of e-commerce sites convert at 5%+. Top 1% reach 10%+. If you're below 2%, there are likely significant UX or offer issues to address before scaling ad spend.


Mobile conversion rates are typically 50-70% lower than desktop. With mobile traffic now dominant, improving mobile conversion experience is often the highest-ROI optimization you can make.

Frequently Asked Questions

How do you calculate conversion rate?

Conversion Rate = (Number of Conversions ÷ Total Visitors) × 100. If 1,000 people visit your page and 30 purchase, your conversion rate is 3%.

What is a good conversion rate?

Average e-commerce conversion rate is 2-3%. Top performers reach 5-10%. B2B landing pages average 2-5%. The "good" rate depends on your industry, traffic source, and what counts as a conversion.

What is the difference between CTR and conversion rate?

CTR (click-through rate) measures how many people click your ad. Conversion rate measures how many visitors complete a desired action on your site. CTR gets people to your page; conversion rate determines if they take action once there.

How do I improve my conversion rate?

Test landing page elements (headlines, CTAs, social proof), improve page speed, match ad messaging to landing page content, add trust signals, and simplify the conversion process (fewer form fields, guest checkout).
