Sales Funnel Google Ads Calculator
Estimate clicks, leads, customers, revenue and return from a Google Ads sales funnel using your budget, CPC and conversion rates.
Overview
This Sales Funnel Google Ads Calculator helps you estimate how a monthly ad budget may translate into clicks, leads, customers, revenue and profit. Enter your budget, average cost per click, landing page conversion rate, lead-to-sale rate, average sale value and margin to model funnel performance.
How it works
The calculator starts by dividing your ad budget by average cost per click to estimate clicks. It then applies your landing page conversion rate to estimate leads and your lead-to-sale rate to estimate customers. Revenue is calculated from customers multiplied by average sale value. Gross profit is estimated using your profit margin, and ad spend is then subtracted to show estimated net profit after ads. Cost per lead, cost per acquisition and return on ad spend help you assess efficiency.
