CPA Calculator

Just like many other metrics, it’s difficult to construct the ideal benchmark across all industries. But if you’re wondering “what is a good cost per acquisition?”, you’ve come to the right place. There is an estimated ideal CPA benchmark for PPC search and PPC display ads across all industries.

Channel	Estimated CPA
PPC Search Ads	$59.18
PPC Display Ads	$60.76

You should use these benchmarks to determine the quality of your CPA and make changes to your campaign accordingly. Is it a little higher? Is it a little lower? Here’s what you should do in each situation:

If your CPA is higher than the benchmark:
You could likely make small changes to your ad campaigns in order to lower your CPA. We’ll talk about what affects your CPA later!

If your CPA is lower than the benchmark:
Congratulations, it means that you’re advertising effectively! You likely don’t need to change anything about your campaign, but you shouldn’t let your foot off the gas, either.

If you’re not using a CPA calculator to determine your cost per acquisition, you might wonder how to calculate CPA on your own. Below, you can find the CPA formula to do so!

CPA = cost of advertising/number of conversions

Easy enough, right? Although the formula for CPA isn’t difficult, there are many benefits that you reap by using a CPA calculator instead.

When you know how to calculate CPA manually, you might wonder if it’s easier to calculate on your own or to use a CPA calculator to help. Before you decide how you want to calculate your CPA moving forward, check out the benefits of using a CPA calculator below!

1. You’ll get it right every time
Whether you’re a math whiz or not, there is always room for error when you calculate something manually. If you choose to use the CPA formula to calculate your cost per acquisition, you could make one small mistake that majorly throws off your metrics.

When you opt to use a CPA calculator, on the other hand, your CPA comes out right every time. You don’t need to worry about incorrect results because the calculator does all the work for you.

2. A free CPA calculator is fast
When you use a CPA calculator, you know your cost per acquisition in seconds. You won’t have to jot down any notes or do long division. You plug in your numbers and your CPA calculator figures out your cost per acquisition for you.

Your time is precious, and if you want to find your CPA for multiple campaigns, you want to save as much time as possible. A free CPA calculator like ours helps you do just that.

3. You can get a read on the health of your ad campaigns
When you calculate cost per acquisition, you reap extreme benefits for your business — more specifically, for your ad campaigns.

After determining your CPA, you’ll get a read on the health of your ad campaign. Here’s what different CPAs tell you about your ad campaign.

If your CPA is more than what a customer usually spends on a single product in your store:
There is room to improve your ads if you find that your CPA is more than a moderately priced item in your store.

Here’s why — if, for example, your CPA is $80 and you’re advertising posters that you typically sell for $10, you’re likely paying entirely too much to convert that user to a customer. It’s unlikely that they’ll ever pay more than the calculated CPA, which means you won’t make a profit from them.

However, you have to account for repeat customers, too. For example, if you only work with colleges who buy your posters for poster sales on campus, $80 is probably a great CPA since they’ll likely spend far more than $80 on your products.

If your CPA is less than what a customer usually spends on a single product in your store:
Your ad campaign is doing its job — and doing it well, if your CPA is a lot less than what a typical customer spends in your store.

This CPA means that you’ll likely always make a profit from your customers since you’re not paying a lot on the ads it takes to acquire them.

The following factors affect CPA the most:

Factor	Reason
Audience targeting	Broad or poor audience targeting allows unqualified users to view (and interact) with your ads, which hurts your acquisition or action costs.
Ad relevance	Ad networks need to deliver relevant ads as a part of their business operations. That’s why advertisers with low-relevancy ads pay more.
Landing page quality	A landing page with a poor user experience, whether due to speed, messaging, or usability, will feed back to your ad performance and impact on-page conversions.

2. Calculating CPA by different ad networks (like Google Ads vs. Microsoft Advertising) vs. altogether

This approach can surface opportunities, whether for running a paid audit or investing in a new strategy, like improving the conversion rate of paid landing pages.

AI bidding capabilities in Google Ads, like Maximize Conversions and Target CPA, affect CPA with the intent to lower it because it predicts the likelihood of a user converting (based on signals you send to Google Ads).

It’s worth mentioning, however, that AI-driven advertising (like Smart Bidding) includes a learning phase where advertisers will see higher costs, as well as constant monitoring due to spammers manipulating the system.
