How much do Facebook ads cost in 2026? CPM, CPC and budget

Facebook ads cost what you decide to spend. Meta lets you set a budget and spending limits, and your bid strategy manages what you pay per result (Meta Help Center). What you can’t set is the price of each impression: an auction decides it, every time an ad can be shown.

So the real question is what your sales goal will cost. To answer it, you need three numbers from your own account: CPM, click-through rate and conversion rate. Until you have them, published medians give an order of magnitude. Work it out with our Facebook ads cost calculator.

Facebook ad costs in 2026: the medians

Triple Whale published Meta ads benchmarks on August 17, 2026: more than 40,000 brands that use its analytics tool, from August 1, 2025 to July 31, 2026, Facebook and Instagram together (Triple Whale).

Triple Whale doesn’t give a cost per click. From these medians, it works out to about $0.63: $15.06 ÷ (1,000 × 2.39%). That’s our calculation.

A few limits before you use these numbers. These brands use Triple Whale, so they are not a random sample of stores. Triple Whale defines CPA as the cost to acquire one customer; below, we use it as a cost per purchase, which is an approximation. Triple Whale doesn’t say which clicks its CTR and conversion rate count. And each median is taken on its own, so they don’t chain exactly: CPM, CTR and conversion rate together give $41.18 per purchase, while the median CPA is $38.99. The yearly changes are the ones Triple Whale reports: they don’t all match its rounded figures.

How Meta sets the price: an auction

Each time there is a chance to show an ad to someone, Meta runs an auction among the ads whose audience includes that person. The winner is the ad with the highest total value, which combines three things (Meta Help Center):

• Your bid: what you are willing to pay for the result you want.
• Estimated action rates: how likely that person is to engage with your ad or buy.
• Ad quality: measured from people’s feedback when they view or hide the ad, and from checks for withheld information, sensational wording or engagement bait.

That’s why a more relevant ad can win against a higher bid. Meta says its adjustments to the auction will never charge you more than your bid. Unless you choose otherwise when you create the ad, you usually pay for impressions (Meta Help Center).

Your budget works as an average. With a daily budget, Meta can spend up to 75% more on a good day, never more than 175% of the budget in a day, and never more than 7 times the daily budget from Sunday to Saturday, if the budget doesn’t change during the week. A $100 daily budget can spend $175 on one day and won’t go over $700 in the week. If you turn on ad set budget sharing, those limits go up to $210 a day and $840 a week (Meta Help Center).

CPM, CPC and cost per purchase: how they connect

CPM is the amount spent divided by impressions, times 1,000 (Meta Help Center). From there, two of your own rates take you to the cost of one sale:

• Cost per click = CPM ÷ (1,000 × CTR). At $15.06 and 2.39%: $0.63.
• Cost per purchase = cost per click ÷ conversion rate. At about $0.6301 (kept unrounded in the calculation) and 1.53%: $41.18.
• Budget = sales goal × cost per purchase. For 100 sales a month: about $4,118.

Your conversion rate weighs as much as your CPM. With the same CPM and CTR, a conversion rate of 2% instead of 1.53% gives $31.51 per purchase. It’s the same arithmetic.

What makes your costs go up or down

Your industry. In the Triple Whale study, the median CPM goes from $11.50 (Baby) to $21.80 (Health & Wellness), and the median CPA from $26.80 (E-learning) to $51.86 (Electronics, and Medical Devices). A few industries common on Shopify:

The year. The median CPM rose 13.24% in a year, and 16 of the 17 industries in the study paid more per 1,000 impressions.

Your ad. Estimated action rates and ad quality are part of the auction. Meta notes that clickbait and engagement bait don’t improve ad performance.

What you optimize for. Meta says some optimization events need more budget than others: optimizing for purchases may need more than optimizing for landing page views (Meta Help Center).

The learning phase. After you create an ad set or make a significant edit, it goes through a learning phase. Meta says it usually ends after about 50 results in the week after the last significant edit, and that ad sets usually have a higher CPA until then (Meta Help Center).

Fees on top of delivery. Meta may add location fees to ads delivered in some countries, to cover digital services taxes (Meta Help Center).

How much do Instagram ads cost?

Instagram ads are bought with the same Meta tools: from the app, from instagram.com, from your Facebook Page, in Meta Business Suite or in Ads Manager, and one ad can run on both Facebook and Instagram (Instagram Help Center). The Triple Whale figures cover both apps together.

Watch for one extra fee in the Instagram app. In most regions, when you add funds to your ad account in the Instagram iOS app, Apple may take a service fee of 30% of your ad payment. Instagram suggests boosting from instagram.com instead.

Is there a minimum budget?

Meta doesn’t publish one figure for everyone. Its Help Center page, read on October 22, 2026, says minimum budgets vary by country and objective. Meta sets them from your business vertical, budget type, buying type, bid strategy, optimization, currency and schedule, and Ads Manager shows an alert when your budget is below the minimum (Meta Help Center).

One rule is written down: if you use the cost per result goal bid strategy, your daily budget should be at least 5 times that goal. A $5 goal means at least $25 a day.

You may read "$1 a day" elsewhere. We didn’t find that figure in Meta’s Help Center on October 22, 2026.

How much do Facebook ads cost per month for a Shopify store?

What matters is how many sales the budget buys at your cost per purchase. At the $38.99 median CPA from the Triple Whale study, used as a cost per purchase (our calculations, 365 ÷ 12 ≈ 30.4 days a month):

To give one ad set the 50 or so results a week that Meta mentions for the learning phase, at that median, you would spend about $1,950 a week (50 × $38.99), or about $279 a day. Below that, your ads can still sell, but the ad set may not get enough results to leave the learning phase: Meta then shows it as "Learning limited". Spending that amount doesn’t guarantee it leaves either. These figures assume one ad set optimized for purchases.

A cost per purchase isn’t good or bad on its own. It depends on what one order leaves you once the product, shipping and fees are paid. Check your break-even point with the ROAS calculator before you set a budget.

Work out your own budget

1. Open Ads Manager and note your CPM and CTR over the last few weeks.
2. Divide your purchases from ads by the link clicks on those ads: that’s your conversion rate. Use the same link clicks for your CTR.
3. Take your average order value from your Shopify analytics.
4. Enter them in the Facebook ads cost calculator with your sales goal. It gives the monthly budget, the cost per click and the cost per purchase, and shows your purchases per week next to the 50 of the learning phase, for one ad set optimized for purchases.

Questions

How much do Facebook ads cost per day?

What you set as a daily budget, averaged over the week: Meta can spend up to 175% of it on one day, but not more than 7 times it from Sunday to Saturday (more if you turn on ad set budget sharing). What that day buys depends on your CPM and your rates.

Is $5 a day enough for Facebook ads?

It can run ads, if it meets the minimum Ads Manager shows for your country and objective. At the $38.99 median CPA, $5 a day pays for about one purchase a week. That’s far from the 50 or so results a week Meta mentions for the learning phase: the ad set may stay "Learning limited".

How much does a Facebook ad cost per click?

From the Triple Whale medians, about $0.63 per click (our calculation from a $15.06 CPM and a 2.39% CTR). Your cost per click is CPM ÷ (1,000 × CTR), with CTR as a decimal (2.39% = 0.0239): a better click-through rate lowers it at the same CPM.

Are Instagram ads cheaper than Facebook ads?

The Triple Whale study gives Facebook and Instagram together, so it can’t answer that. Both are sold through the same auction and the same tools, so the answer has to come from your own account’s results.
