How to Get More Leads From the Same Budget
Improve your landing page
Raising the click to lead rate from 3% to 6% doubles your leads without spending a rupee more.
Lower your cost per click
Better Quality Score means cheaper clicks. See our guide on how to reduce Google Ads CPC.
Add negative keywords
Stop paying for searches like "free" or "jobs" if you sell a paid service.
Call leads quickly
A lead called within minutes is far more likely to buy than one called the next day. It raises your lead to sale rate.
Target your area
Local businesses should show ads only around their service area. Read Google Ads for local business.
Track every conversion
Set up form and call tracking, so Google's bidding learns which clicks bring real leads.

Frequently Asked Questions
How much should I spend on Google Ads per month?
Start from your goal. Decide how many leads you need, then use this calculator with your real cost per click and conversion rate to see the budget that requires. Test with a smaller budget first and scale what works.
What is a good ROAS for Google Ads?
It depends on your profit margin. A ROAS above 1 means revenue is higher than ad spend, but you also need to cover product and staff costs. Many businesses aim for 3 to 4 or more.
What is break-even CPC?
It is the highest price you can pay for a click before ads start losing money, based on your conversion rates and sale value. If your real CPC is above it, fix your landing page or targeting first.
Where do I find my average cost per click?
For a new campaign, use Google Keyword Planner's top-of-page bid ranges for your keywords. For an existing campaign, use the Avg. CPC column in your Google Ads account.
Why does Google Ads use 30.4 days for monthly budgets?
30.4 is the average number of days in a month. Google Ads multiplies your daily budget by 30.4 to set the most it will charge you in a month.
Is this calculator free?
Yes. It is free, needs no sign-up, and nothing you enter leaves your browser.
