Estimate your Google Ads costs before you spend a dollar.
Google Ads can be the most profitable channel you have — or a fast way to burn money. The difference comes down to one question: do your click costs and conversion rate work together? Here is how to check before you spend.
1 free report. Real CPC data for your keywords.Capture rate is the share of monthly searches you win as clicks through paid ads. CPC is your cost per click from the Google Ads auction.
What determines Google Ads cost?
Google Ads uses an auction system. The cost per click (CPC) for any keyword depends on how many advertisers are competing, how much they are willing to pay, and how relevant their ads are. High-commercial-intent keywords (like "buy running shoes") cost more than informational ones (like "best running shoes 2024").
Your total cost is CPC multiplied by the number of clicks you receive. The number of clicks depends on search volume and your capture rate — what share of searches you win.
How to estimate your total ad spend
The formula is simple in principle:
- Monthly ad spend = (monthly searches x capture rate) x CPC
- Example: 10,000 searches x 3% capture = 300 clicks
- At $2 CPC: 300 clicks x $2 = $600/month in ad spend
When do Google Ads make sense?
Google Ads make sense when your customer acquisition cost (CAC) is lower than the profit each customer generates. CAC for paid search is CPC divided by your conversion rate.
If CPC is $2 and your conversion rate is 3%, CAC is $67. If your profit per customer (after variable and fixed costs) is more than $67, the campaign is profitable. If it is less, every customer you acquire through ads loses money.
Model different scenarios
The real power is in modelling: what if your CPC is 20% lower? What if your conversion rate is 5% instead of 2%? What if you raise your price by $30? Each of these changes the profitability equation.
The report lets you model all of these in one place — adjusting CPC caps, capture rates, conversion rates, price, and costs to find the combination where paid search becomes profitable.

Common questions.
Is the CPC data accurate?
The report pulls CPC estimates from live Google Ads data. Actual CPCs vary based on your ad quality score, landing page relevance, and competition at the time of the auction — but the estimates are close enough to make go/no-go decisions.
How much should I budget for Google Ads?
Start with the break-even analysis. If your break-even conversion rate is realistic (under 5% for most products), start with a test budget of 2-3x your expected monthly spend to gather enough data. The report shows you what that spend would look like.
Can I estimate costs for specific locations?
Yes — select a country when creating the report. CPC varies significantly by location. For local businesses, use local service keywords to get a realistic CPC for your market.
