Conversion Rate Calculator
Calculate your conversion rate from visitors and conversions, and see how many conversions you need to hit a target rate.
About the Conversion Rate Calculator
Conversion rate is the fraction of visitors who take the action you care about — buying, signing up, filling a form. Enter your visitor count and conversion count and this calculator returns the rate instantly, plus conversions per 1,000 visitors, a scale that is often easier to reason about for low-rate funnels.
Add an optional target rate and it also computes how many total conversions that target implies at your current traffic and how many additional conversions you'd need — the number your optimisation work actually has to deliver. The formula is conversions ÷ visitors × 100, but consistency matters more than the arithmetic: measure visitors and conversions over the same period and define 'visitor' the same way every time (sessions vs unique users give different rates).
Typical e-commerce conversion rates sit around 2–4%, SaaS trial signups higher, cold landing pages lower. Compare against your own history first — a rate that doubles from 1% to 2% is a bigger win than chasing someone else's benchmark.

Frequently Asked Questions
How do I calculate conversion rate? A worked example
Conversion rate = conversions ÷ visitors × 100. With 12,500 visitors and 340 conversions: 340 ÷ 12,500 × 100 = 2.72%. That's also 27.2 conversions per 1,000 visitors.
How many more conversions do I need to reach a target rate?
Multiply the target rate by your traffic. To hit 4% on 12,500 visitors you need 0.04 × 12,500 = 500 conversions — 160 more than the current 340. The calculator does this automatically when you enter a target.
What is a good conversion rate?
It varies wildly by industry, traffic source and what counts as a conversion. E-commerce averages roughly 2–4%; landing pages for paid ads often see 5–15% for lead capture; cold display traffic can convert below 1%. Benchmark against your own past performance and near-identical competitors, not global averages.
Should I measure by sessions or unique visitors?
Either works if you stay consistent. Session-based rates are lower (one user may visit three times before buying — one conversion over three sessions). Session-based suits per-visit UX questions; user-based suits questions about what share of your audience eventually converts.
My conversion rate dropped after traffic grew — is something broken?
Not necessarily. New traffic sources usually convert worse than your warm core audience, so a traffic spike from a viral post or broad ad campaign often lowers the blended rate while total conversions still rise. Segment the rate by source before diagnosing a problem.
