What is Facebook Ads Cost and How to Spend Less in 2025

"Senator, we run ads."

In 2018, Mark Zuckerberg faced what many presumed would be the demise of Facebook: standing in front of the U.S. Congress, in the wake of the Cambridge Analytica scandal.

Much has changed since then, but that moment marked the beginning of a new era in social media advertising. Years later, Facebook is still here and the platform’s advertising costs are through the roof.

In 2021 alone, Facebook registered more than $114 billion in ads revenue, showing the interest in advertising is growing (just one year before, they had $84 billion).

Despite all the scandals, Facebook Ads remains one of the most lucrative platforms to use when you want to monetize your digital marketing funnel.

How much does it actually cost to run ads on Facebook - and how can you spend less in 2024?

Here's what you need to know.

How does the Facebook ad auction work?

Facebook Ads is a pay-per-click (PPC) advertising platform. The ads you see on Facebook are the result of a bidding process, known as an “ad auction”, which takes place when someone places a bid for a specific target audience.

In this ad auction, advertisers compete to have their ads displayed by offering bids based on how much they're willing to spend on a campaign or acquire a customer. The bids are then weighed against other factors, such as the audience the ad is targeting and the quality of the ad itself.

The higher an advertiser's bid, the more likely their ad is to show up on their target audience's news feed or sidebar. It's also possible for an advertiser to get a lower cost-per-click (CPC) if their ad has higher quality and relevance. This is because Facebook rewards advertisers who create ads that provide a good user experience.

Facebook Ads also offers options for optimizing campaigns, such as automatic bidding - where they automatically raise or lower bids to get better results and maximize campaign performance by focusing on ad sets that are doing well. This kind of Facebook automation ensures that advertisers get the most out of their campaigns and reach their desired audience.

By understanding how Facebook Ads work advertisers can create effective ad campaigns and maximize the impact they have on their target customers. With its powerful auction system, the platform provides a great way to reach potential customers and increase conversions.

How much do Facebook Ads cost?

Facebook bills advertisers based on different metrics. The most common ones are cost per click (CPC), cost per mille (CPM), and cost per lead (CPL). CPC is the cost for every click your ad receives, CPM is the cost per thousand impressions your ad receives, and CPL is the cost for every lead generated through Facebook Ads.

Generally speaking, campaigns with larger advertising budgets tend to be more effective since they have access to a wider range of features and options that can help them optimize their campaigns and get more traction.

Average CPC for Facebook Ads

The average CPC on Facebook is around $1. Of course, a variety of factors influence this number. All in all, though, you should expect to pay about $0.94 for every click or $12.07-$14 for 1,000 impressions you get on your Facebook Ads.

Here's how this translates in business terms:

If you're selling a product that costs $50 and your conversion rate is 2.5 - 3% (average for eCommerce, for example), you'll need to generate 33 - 40 clicks to get one sale.

At an average CPC of $1, that would require a budget of at least $33 - which means that the remainder of $17 will be your profit.

However, if your product is less than $33, you might have to adjust your advertising strategy to bring the CPC to under $1. You can do this through a combination of different tactics, such as retargeting or A/B testing (see more about this below).

Average CPM for Facebook Ads

If you'd much rather pay by the number of impressions, learn that the average CPM for Facebook Ads is around $14. Same as in the case of CPC, CPM is sensitive to a variety of factors (which we'll discuss in greater detail below.)

What this means is that if you're running a branding campaign, intending to reach 500,000 people, then at an average CPM of $14, you'll need a budget of $7,000.

Average cost per lead

According to Revealbot, the average Cost per Lead (CPL) in Facebook Ads is around $5. However, it is worth keeping in mind that not all leads convert - so you should take into account your average conversion rate (once potential buyers are officially marked as leads.)

The type of lead you’re aiming to generate will influence the cost per lead. For example, a free trial or a demo request will cost more than a newsletter subscription. Also, your industry and available target options will also influence your CPL.

What determines your Facebook ad cost?

The cost of ads on Facebook depends on a lot of factors. Some of the most important ones include:

Ad budget

Facebook allows you to set a fixed ad budget, which will determine whether you reach more people or not. The more money you spend, the larger your potential audience is going to be. However, when you are just starting out, you might want to test a small budget (and then scale accordingly).

Ad bid

Your bidding strategy will also influence how much your Facebook Ads cost. There are three main bidding strategies in Facebook Ads:

• Goal-based (pay per-result goal or pay by ROAS)
• Spend-based (based on the highest volume or the highest value)
• Manual (where you put a manual cap on each bid, rather than allow Facebook to automatically cap your bids which is called automatic bidding.)

Goal-based and spend-based bidding are automated by Facebook's system, whereas a manual bid strategy is something you can do yourself.

To make sure you choose the right type of ad bid, you should first make sure you have a solid marketing strategy and understand how the Facebook Ads algorithm works. Essentially, the system will rate each bidder and ad according to three main criteria:

• Bid: how much do you want to pay for each user interaction with your ads
• Estimated auction rates: how likely it is that users will interact with your ads
• Ad quality and relevance: how closely your ad aligns with user interests, how well it resonates with them, and what is the perceived quality of the ad

If your ad comes out with a high score from this three-tiered assessment, you win the bid. Theoretically, an aggressive bid strategy will help you win - but it might also drive your cost per conversion up.

Ideally, you want to strike the right balance between all these key factors and find the sweet spot. And that’s where you should use the expertise of a Facebook Ads expert to help you optimize your bids.

Ad objective

The cost of your Facebook Ads will depend on the marketing objective you've set for your campaign: brand awareness, reach, traffic, app installs, link clicks, video views, etc. If you choose the wrong ad objective, you might end up spending more because the automated bidding process will match your goals.

Audience

When you bid on ad placement, you're competing with businesses in your industry and businesses in other industries that target the same audience as you. So if you target an audience many others are targeting, the cost of your ads will go up. Who your audience is and your audience size will influence your ad spending.

Use custom audiences for every part of your marketing funnel, and constantly feed them with your business data (via social media and email platforms).

Ad quality

Every Facebook ad with more than 500 impressions receives a relevance score, which is an indicator of how your audience reacts to your ad. The higher the relevance score, the more affordable your ads will be.

To make sure your ads have a high relevance score, you need to create content that resonates with your audience, use the right images, and include a clear call to action.

Ad placement

If your ad placement is competitive, you will pay more for your ads. Think of it like real estate: houses in very good neighborhoods are more expensive than those in less popular neighborhoods. Likewise, ad placements on Facebook that have more visibility (like the News Feed) will be pricier than those in less visible areas.

Facebook allows you different ad placements such as on Instagram and the Audience Network to maximize your reach and get more customers.

Industry

Your industry also influences your campaign costs. Industries like finance, legal services, B2B, customer service, and insurance are usually more competitive than others, meaning that their CPC tends to be higher.

Season

If everyone rushes to go on beach vacations in July in a given area, the accommodation and flight prices will go up. The same is true for ads: when a lot of people are advertising in the same industry in a specific season, the cost of the ads will skyrocket. For instance, you might end up spending more on the same ad if you publish it around Black Friday than you would on a random day in June.

Time of day

Ads tend to be more expensive during peak times when people are most active on Facebook. Generally, the cheapest times of day to target are during nighttime and the best period of time to schedule ads on Facebook is from Wednesday to Friday, from 8 to 9 am (when most people start their work day).

Location

Your location might also influence how much you spend on your ads. If a lot of people bid on local ad space, the cost of those ads goes up.

9 ways to reduce your Facebook ad cost

Facebook Ads only make sense if they yield a reasonable cost per acquisition (CPA). Otherwise, you’re just wasting your marketing budget on a channel that’s not sustainable. Here are 9 tips to reduce your Facebook ad cost:

1. Choose the right campaign objective

If you choose the wrong campaign objective, you will spend more and get less. Here's an example: if you're advertising beauty products for women, and want to set up a bottom-of-the-funnel campaign, choosing the reach objective isn't the best choice because it will not necessarily drive sales.

Instead, choose more targeted objectives like conversions. This way, the automated Facebook bidding system will know how to use your advertising budget to get better results.

2. Narrow down your audience

The larger your audience is, the more businesses you're competing with. Narrowing down your audience is a great way to decrease your Cost per Click (CPC).

To do this, you need to get as detailed as possible in the Audience Insights section of the Ads Manager. For example, if you sell beauty products for women, you could target specific ads to specific groups of women (age, interests, type of skin as shown by previous browsing history, etc.). This is more efficient than, say, targeting all women in a country.

A tool like Klaviyo can help you build smart marketing campaigns around this. Because it connects to Facebook audiences and your website, Klaviyo can help you target your campaigns and take your leads past the Facebook ad click and into making a purchase.

3. Lower your ad frequency score

The more your ads appear in the same format on the platform the less likely your users are going to engage with them. This is called ad fatigue and it’s the reason you should decrease your ad frequency score.

If you see a low action rate on your ads it might mean it’s time to change up your ad creatives or messaging. So refresh your ads every few days or weeks, and test out different designs and ad placements. This will also help you avoid ad fatigue and keep your CTR high.

4. A/B test ad creatives and placements

A/B testing (or multivariate testing) is key to running any kind of successful marketing or advertising campaign. Many times, you don't know what works and A/B testing allows you to compare different versions of your ads to optimize them.

Make sure you only change one variable in your A/B testing variants. Otherwise, you won’t know which variable affected the outcome.

For example, you can either change the ad copy, the creative, or the placement (desktop vs. mobile), but not all of them at once. You could also test different bids and budgets. This way you'll get a comprehensive overview of what works (and what doesn't).

5. Make your ads relevant

There's no point in running ads that aren't relevant to your target audience. Not only will this hurt your CTR, but it will also waste a lot of money in the ad bidding process (because your relevance score will be lower). Keep your ads relevant both in terms of content and in terms of targeting.

6. Run retargeting campaigns

Retargeting campaigns are an effective way to re-engage users who have already interacted with your business in some way. This could be anything from visiting your website to liking your Facebook page to filling out an online form.

Retargeting campaigns allow you to target those people who already know and trust your business. As a result, it will get you better conversions at lower costs than what you’ll get with cold traffic.

7. Improve the post-click experience

The post-click experience is just as important as the pre-click one. If you direct people to a slow or poorly designed website or landing page, they'll almost instantly leave, which means a lower conversion rate and more costly ads. So you need to optimize the entire marketing funnel and make sure your user has a good experience from click to purchase, and beyond.

8. Hire a Facebook Ads agency

Running ads on Facebook can feel overwhelming. There are many elements to consider and sometimes the cost of your ads on Facebook can be discouraging. Hire an expert Facebook Ads agency to save on ad costs and make sure your campaigns are successful.

Experienced advertising pros and Instagram Ads managers know how to effectively optimize campaigns and get the most out of your budget. They also have decades of experience behind them, so they know how to test different elements to maximize results for the lowest cost possible.

9. Use lookalike audiences

Facebook lookalike audiences allow you to tap into audiences similar to those who already made a purchase from you. How this works is that Facebook takes a small group of your users (e.g., people who have already purchased your product) and then finds similar audiences that fit those same parameters.

Lookalike audiences are great for increasing reach and building brand awareness. They also help you find high-quality leads at a lower price with minimum optimization effort.

Recap

Facebook Ads is one of the highest ROI marketing channels out there. However, whether Facebook Ads is worth it or not depends on a variety of factors - including your business model, bidding strategy, average click-through rates, engagement rates, and other metrics.

Advertising isn't a magic wand. You can't just put money in it and expect a mind-blowing ROI overnight. While it’s generally a quicker way to acquire new customers (compared to organic channels), make sure you set the right expectations for your advertising efforts.

Facebook Ads is no exception: if you want them to get you a good ROI, you need to pursue ad optimization: to constantly tinker, adjust, and re-strategize. Need a hand? Talk to one of our expert Facebook marketers.
