Conversion rate is the percentage of visitors or leads who take the action you care about, whether that is a purchase, a signup or a booked call. It is the core metric of marketing and sales optimization because small improvements compound across every visitor. This calculator divides the number of conversions by the total number of visitors and returns the rate as a percentage. It also shows how many visitors you need on average to earn one conversion, which is handy for forecasting traffic goals. Marketers use conversion rate to compare landing pages, ad campaigns and funnels, and to prove that a change actually moved the needle. Enter your conversions and visitors and the rate appears immediately. Track it before and after each experiment to see what works. All math runs locally in your browser, so your funnel data never leaves your device.
