How cost per lead is calculated
Cost per lead is simply total ad spend ÷ number of leads. This tool works out the leads from your clicks and landing-page conversion rate, then extends the picture: leads close into customers at your close rate, giving cost per customer (CAC), and each customer's value gives your return on ad spend (ROAS) and gross profit.
The two biggest levers on CPL are landing-page conversion rate and click quality — doubling conversion rate halves your cost per lead without spending a rupee more. If your CAC is higher than your customer value, the campaign loses money on the first sale and needs repeat purchases or better targeting to work. Want us to pressure-test your actual campaigns?
