What is Conversion Rate?
Conversion Rate is the percentage of website visitors who complete a desired action. Whether it's making a purchase, signing up for a newsletter, or filling out a contact form—conversion rate tells you how effectively your site turns visitors into customers.
Our calculator offers 3 modes: Calculate your basic conversion rate, estimate the revenue impact of CRO improvements, or compare A/B test variants to find winners.
Conversion Rate Optimization (CRO) is the practice of improving this metric. Even small improvements—like going from 2% to 3%—can increase revenue by 50% without any additional traffic.

Conversion Rate Formula
Example: 250 conversions from 10,000 visitors = 2.5%
Industry Conversion Rate Benchmarks
| Industry | Average Rate | Good Rate | Top 10% |
|---|---|---|---|
| E-commerce (General) | 1-3% | 3%+ | 5%+ |
| B2B SaaS | 2-5% | 5%+ | 7%+ |
| Landing Pages | 5-15% | 15%+ | 25%+ |
| Lead Generation | 2-5% | 5%+ | 10%+ |
How to Improve Conversion Rate
Speed up page load (every 1s delay = 7% loss).
Simplify forms (fewer fields = more submissions).
Add trust signals (reviews, badges, testimonials).
Improve CTAs (clear, action-oriented buttons).
A/B test everything (headlines, images, layouts).
Mobile optimize (60%+ traffic is mobile).
Common CRO Mistakes
Ending tests early: Wait for statistical significance.
Testing too many variables: One change per test.
Ignoring segments: Mobile vs desktop rates differ.
Frequently Asked Questions
How do I calculate conversion rate?
Conversion Rate = (Conversions ÷ Visitors) × 100. Example: 250 conversions from 10,000 visitors = 2.5% conversion rate. The 'conversion' can be any goal: purchase, signup, download, etc.
What is a good conversion rate?
It varies by industry: E-commerce averages 1-3%, B2B SaaS 2-5%, landing pages 5-15%. Above average is 'good.' Top performers achieve 2x industry average. Focus on improving YOUR rate, not just benchmarks.
What is CRO (Conversion Rate Optimization)?
CRO is the practice of improving your conversion rate through changes to your website, landing pages, and user experience. It includes A/B testing, UX improvements, copy optimization, and reducing friction in the conversion funnel.
How much can CRO improve revenue?
Doubling conversion rate doubles revenue from existing traffic. Even a 0.5% improvement can mean significant revenue. Use our Revenue Impact mode to calculate exactly how much a rate improvement is worth for your business.
What counts as a conversion?
A conversion is any desired action: purchase, form submission, email signup, download, phone call, chat initiation, video view, or button click. Define your conversion based on your business goals.
How do I run an A/B test?
Create two versions: A (control) and B (variant with one change). Split traffic 50/50. Run until statistically significant (usually 1-2 weeks). Compare conversion rates. The winner becomes your new control.
What is statistical significance in A/B testing?
Statistical significance (typically 95%) means there's only a 5% chance the result is due to random variation. Larger sample sizes and bigger differences reach significance faster. Don't end tests early.
Why is my conversion rate low?
Common causes: 1) Wrong traffic (targeting issues). 2) Slow page load times. 3) Confusing UX or navigation. 4) Lack of trust signals. 5) Weak value proposition. 6) Friction in checkout/forms. Analyze your funnel step by step.
Should I use visitors or sessions for conversion rate?
Sessions is more common and practical—it measures each visit opportunity to convert. Unique visitors may undercount since one person can convert on a return visit. Be consistent with your metric choice.
How often should I check conversion rate?
Track daily/weekly trends, but don't overreact to short-term fluctuations. Monthly analysis is best for identifying real patterns. Seasonal variations, traffic sources, and device types can cause normal fluctuations.
