Step 1
Start with a lead goal
Choose the number of qualified inquiries the business could respond to well in one month, not the biggest number that sounds exciting.

Google Ads Budget Calculator
Work backward from the qualified leads you want. The calculator estimates the clicks, total inquiries, monthly spend, and economics needed to support that goal.
Example numbers are included. Replace every field with your own.
Your numbers
Use recent campaign and sales data when available. New advertisers can begin with the example and test a range.
The number of sales-worthy inquiries you want Google Ads to produce.
Use a recent account average or a realistic planning estimate.
The share of ad clicks that become calls, forms, or booked appointments.
The share of inquiries that match your location, service, budget, and timing.
The share of qualified leads expected to become paying customers.
Use the average value of a new sale or signed job.
Revenue remaining after direct fulfillment cost.
Estimated monthly Google Ads budget is $4,898, or $161.12 per day.

The theoretical ceiling before overhead and profit goals.
At these assumptions, projected gross profit exceeds ad spend by approximately $11,602 before overhead.
See how these numbers are calculated
- Total inquiries needed = qualified lead goal ÷ qualified lead rate.
- Clicks needed = total inquiries ÷ landing page conversion rate.
- Monthly media budget = clicks needed × average cost per click.
- Expected customers = qualified leads × qualified lead close rate.
- Maximum break-even CPC = gross profit per sale × close rate × qualified lead rate × landing conversion rate.
Auction prices and conversion rates change. Use this as a planning range, then replace assumptions with real campaign and CRM results.

How to Use It
A better estimate starts with numbers you can explain.
Work backward from the number of leads you want using your expected click cost, landing-page conversion rate, close rate, customer value, and margin.
Step 2
Use grounded assumptions
Enter a realistic average click cost, landing-page conversion rate, sales close rate, customer value, and gross margin.
Step 3
Check the whole path
Review the budget beside projected customers and gross profit. A cheaper click is not helpful when the search intent or lead quality is weak.
Read the Result Well
The number is useful when the assumptions stay visible.
Use the output to compare scenarios, ask sharper questions, and decide what deserves a closer look. It is a planning aid, not a promised result.
Budget follows the funnel
A lead goal requires enough clicks, and those clicks require enough budget. Better landing-page conversion can reduce the traffic needed to reach the same goal.
Cost per click is not the finish line
The business outcome depends on the search terms, page experience, lead quality, response time, and close rate after the click.
Plan for learning
A very small budget may not create enough qualified activity to judge a campaign fairly. A larger budget still needs limits, clean tracking, and regular search-term review.
Questions
Common questions about the google ads budget calculator
Straight answers about the math, the limits, and how to use the result.
How much should a business spend on Google Ads?
The useful answer depends on click cost, conversion rate, lead goal, close rate, customer value, and margin. This calculator connects those inputs instead of using a universal percentage of revenue.
What landing-page conversion rate should I enter?
Use your own qualified-lead rate when it is available. If you are planning a new campaign, test a conservative range and compare the budget under each scenario rather than treating one assumption as a promise.
Does this include management fees?
The main result estimates media spend paid to Google. Add management, creative, call tracking, landing-page, or software costs to the total investment when you evaluate the full return.
