Enter your target leads per month and industry. Get your recommended Google Ads budget based on real CPL and CPC benchmarks from 200+ US campaigns.
The calculator uses three inputs: your target leads per month, your industry's average CPC (from WordStream's benchmark data), and your landing page conversion rate. Formula:
Required Clicks = Target Leads ÷ (CVR ÷ 100)
Recommended Budget = Required Clicks × Industry Avg CPC
Benchmarks sourced from WordStream (2024) and LeadsuiteNow campaign data (2015–2025).
The right Google Ads budget depends on your industry's average CPC, your target number of leads, and your landing page conversion rate. Use the calculator above for a personalised estimate. As a rough guide: to generate 50 leads/month in B2B Services (avg CPL $135), you need approximately $6,750/month. Lower-CPL industries like eCommerce need significantly less.
Google Ads has no minimum budget, but a budget below $500–$1,000/month in most industries won't generate enough data to optimise effectively. LeadsuiteNow recommends a minimum of $1,500/month for service businesses and $3,000/month for competitive industries like legal, healthcare, or finance.
Budget directly controls your impression share — the percentage of eligible searches where your ad appears. A limited budget causes your ads to stop showing partway through the day. Google recommends setting your daily budget to allow at least 10 clicks per day to generate enough data for Smart Bidding to optimise effectively.
