Google Ads Cost Per Lead Calculator for Service Businesses
💰 How Many Leads Can Google Ads Really Get You?
Running ads on Google is one of the fastest ways for service-based businesses to generate qualified leads, but your actual Cost per Lead (CPL) depends on more than just your budget and cost per click.
That’s why we built the Google Ads Leads Calculator (below). It lets you plug in your monthly budget, industry, and landing page quality to instantly forecast how many clicks and leads you could expect, plus your estimated CPL.
How to Use This Calculator
- Enter your monthly budget.
- Choose your industry.
- Select your landing page quality.
The calculator will estimate:
- Average CPC in your industry
- Adjusted conversion rate
- Estimated leads per month
- Estimated Cost per Lead
Use this as a benchmark to compare where you are today, and what you could achieve by improving your landing page quality and overall funnel.

This calculator uses the latest available benchmarks for Google Search Ads in Australia (2024–2025), combined with global conversion rate data for lead-generation industries.
Average CPCs (Cost per Click) are based on published benchmarks from Australian performance agencies and cross-checked against Google Ads cost data for competitive verticals.
Conversion Rates (CVR) come from WordStream’s 2025 Google Ads Benchmarks Report, aggregated from 16,000+ advertisers worldwide, focusing on Search campaigns only.
Industries included cover 19+ verticals, including Legal, Finance, Real Estate, Education, Healthcare, Trades, Professional Services, Automotive, Recruitment, SaaS, Solar, Cosmetic Services, and Hospitality.
Landing page multipliers are applied to CVR to show how much performance typically improves when moving from a standard website to an optimised or high-performance landing page.
Disclaimer: These figures are directional benchmarks — actual performance depends on offer, targeting, competition, seasonality, and landing page quality.
Why Landing Page Quality Matters More Than You Think
Most businesses think results come down to bidding the right keywords and writing good ad copy. That’s only part of the equation. The real leverage point is your landing page — the page people see after they click.
- Standard website: Many businesses send paid traffic to their homepage or a generic service page. These pages are rarely designed for conversions, so conversion rates are low.
- Optimised landing page: A purpose-built landing page focuses on one clear action (enquiry, booking, or quote). With stronger design, messaging, trust signals, and mobile performance, conversion rates can jump by 60% or more compared to a standard site.
- High-performance landing page: When you integrate advanced CRO techniques — persuasive copywriting, social proof, tailored offers, live chat, speed optimisation, and remarketing, the uplift can be even greater. Our benchmarks show 2–3x more leads from the same ad spend compared to a standard website.
That’s why the calculator lets you toggle between Standard, Optimised, and High-performance landing pages. It shows you how dramatically CPL shifts depending on landing page quality.
Why You Need More Than a “Google Ads Expert”
Hiring someone who only runs Google Ads is like having a pilot who can take off but doesn’t know how to land. You’ll get clicks, but will they convert?
A full-stack digital marketing partner looks at the entire funnel:
- Ad strategy – precise targeting, keyword selection, and budget allocation.
- Creative & copywriting – ads that cut through and pre-frame the user.
- Landing pages – built to convert, not just to look pretty.
- Trust signals – reviews, case studies, proof points.
- Automation & nurturing – ensuring no lead gets wasted.
When these layers are working together, your Cost per Lead falls dramatically by 30–70% compared to “ads-only” approaches.
Final Thoughts
Google Ads is powerful, but ads alone aren’t enough. The businesses winning today are those that invest in the full stack: smart ads, persuasive landing pages, trust-building content, and automated follow-up.
That’s the difference between paying $600 per lead and $150 per lead with the same budget
