Free online conversion rate calculator. Calculate conversion rates, required visitors, and target conversions for e-commerce, SaaS, and marketing campaigns. Pure client-side, no ads.
Conversion rate is a key marketing metric that measures the percentage of visitors who complete a desired action (purchase, sign-up, download, etc.). This calculator helps you compute your conversion rate, plan how much traffic you need to reach a goal, or estimate how many conversions you can expect from a given traffic volume. All calculations happen entirely in your browser — no data is ever sent to a server.
Conversion rate is the percentage of visitors who complete a desired action on your website, such as making a purchase, signing up for a newsletter, or downloading a file. It is calculated as: (Conversions / Visitors) × 100%.
A good conversion rate varies by industry. E-commerce averages 2-3%, SaaS free trials often see 5-10%, landing pages can reach 10-20%, and B2B lead generation typically ranges 1-3%. The best benchmark is your own historical performance.
Common strategies include A/B testing headlines and CTAs, simplifying checkout forms, adding social proof, improving page speed, and using targeted landing pages.
Yes. This calculator works for any conversion event: sales, sign-ups, downloads, leads, form submissions, or any other goal you define.
