What is CPM, and what does it cost in 2026? Real numbers from Meta, Google, Reddit and ChatGPT ads

CPM is the cost of showing your ad 1,000 times. The letters stand for cost per mille, and the sum is simple: what you spent, divided by your impressions, times 1,000. Spend $500, get 100,000 impressions, and your CPM is $5. Few advertisers publish theirs, so we went and found ad accounts on screen in 2026 videos.

We searched YouTube for videos on CPM, CTR and click costs across Meta, Google, YouTube, TikTok, LinkedIn, Reddit and ChatGPT ads, screened 80, and kept the 23 uploaded since November 2025 that gave concrete numbers. We added 3 from our earlier studies. That gave us 30 CPM numbers. Seven came from a real account; the rest were rules of thumb, worked examples, reported prices and two unsourced averages. We then checked them against WordStream and LocalIQ's 2026 reports and OpenAI's help pages.

How CPM works, and how to estimate it

CPM, CPC and CTR are tied together. CPM equals CPC times CTR times 1,000. If your clicks cost $1 and 1% of people click, you are paying $10 per 1,000 impressions. That lets you estimate a CPM from reports that only give click costs and click rates, which we do further down.

It also tells you why a CPM alone means little. A $30 CPM with a 3% click rate gives you $1 clicks; a $10 CPM with a 0.3% click rate gives you $3.33 clicks. TrueProfit makes the same point: a $30 CPM can be a great one if it brings profitable customers.

Meta CPM in 2026: what the accounts showed

Antonio Ventre, who runs ads for ecommerce brands, put client accounts on screen. A supplement brand paid $30 per 1,000 impressions in the US alone over 30 days in April, and $10 where the ads also ran in other markets. A toy brand two months after launch paid $25 in December, which is peak season. He also says brand-new US supplement brands can face $145 to $200, and that a new ad account with no history launching supplement ads starts around $200.

The rules of thumb sit in the same range. Máté Hunyor uses $20 to $25 as his benchmark for US campaigns, says up to $50 can still be profitable, and calls $100 a sign to fix the audience or the ad. LYFE Marketing says some businesses pay $10 and others $20 or more. TrueProfit cites an $8.15 Meta average from 2026 data it does not source. Jason Gan says there is no CPM benchmark: it depends on the country and the campaign, so he compares each campaign with its own history.

One trend did come with a dataset behind it. Blue Sense Digital says Meta CPMs have risen about 20% to 30% a year across more than $150 million of ad spend in accounts connected to its business manager.

When CPM jumps

CPM is an auction price, so it moves when other advertisers move. Jason Gan illustrates it with a CPM that used to be $10 rising to $20 when more advertisers, or your competitors, enter the auction for the same audience: the same budget then reaches half as many people. Ventre's toy brand paid $25 in December, its peak month. In Gan's other video, a jump from a $10 baseline to $50 means something is wrong: he would stop the campaign, find the cause, often in the settings, and relaunch.

Raising the bid rarely helps. If CPM rises and click rate holds, the auction got busier and you either accept it or pause until it calms down. If CPM rises and click rate falls, it may be a tired ad, or a holiday that distracts people; check the calendar, then replace the ad. Narrow audiences make both worse, because the platform runs out of cheap people to show the ad to.

ChatGPT ads: a launch price and three real accounts

ChatGPT ads went from nothing to the most expensive real-account CPMs in our data. OpenAI started testing them in the US on 9 February 2026, shown below answers to Free and Go users. Two videos, from QuHarrison Terry and Amazon Seller School, repeat the widely reported launch price of about $60 per 1,000 impressions. OpenAI's advertiser help page now lets you buy by impressions with a maximum CPM bid or by clicks with a maximum CPC bid, and recommends starting click bids at $3 to $5.

Blake Bauer calls his client's CPMs fine for a sales campaign and poor value for a clicks-only one. Grow My Ads thinks it paid at the top end because it targeted people looking for a Google Ads agency, one of the priciest audiences there is. William Zhang calls his $63 CPM very expensive.

Google display, YouTube and Reddit

The cheapest impressions in our data were on Google. Jerad Larkin of Chicago Title shows $2,450 of lifetime spend on display and YouTube awareness campaigns for about 423,000 impressions, which is about $5.79 per 1,000, and one campaign at $83.32 for about 27,700 impressions, about $3.01. He suggests bidding a $10 viewable CPM and expecting to beat it. TrueProfit's unsourced table puts YouTube at $2.16. Chris Shupe, from his own and his clients' YouTube spend, puts the price of one impression anywhere from a fraction of a cent to 4 or 5 cents, which is up to $40 or $50 per 1,000 for the most targeted campaigns.

WordStream's 2026 display report does not give CPM, but it gives median click costs and click rates by industry, which is enough for a rough estimate.

On Reddit, a presenter on HubSpot Marketing's channel ran a one-week test with $100 of her own money. Reddit spent $80 of it for 9,244 impressions and 93 clicks: about $8.65 per 1,000 impressions, an 84-cent click and a 1% click rate.

The same arithmetic on the rounded global LinkedIn averages cited by James Green, who runs B2B ads, a 0.5% click rate and a $5.50 click, gives about $27.50 per 1,000 impressions. B2B buyers are expensive to reach.

What a good CPM is

There is no single good CPM. The rules of thumb we heard for Meta in the US ran from $10 to $25, with $50 still workable for some. A better test is the one Gan uses: compare a campaign with its own past weeks. A jump from your usual CPM, with no change in what you are running, usually points to new competition in the auction or a tired ad. If CPM climbs and click rate holds, your cost per click rises in step; if both move the wrong way, change the ad first.

We would ask three questions before comparing with anyone else's number:

1. What is it per click? Divide CPM by 1,000 times your click rate: a $30 CPM at 3% is $1 a click. A high CPM with a high click rate can still mean cheap clicks.
2. What is it per customer? Judge the campaign on cost per lead or sale. CPM only matters through those.
3. Who are you paying to reach? On ChatGPT, a music lessons business paid CA$26 to CA$34 per 1,000 and an agency chasing Google Ads buyers about $120. The audience moves the price as much as the platform does.

Our CTR benchmarks for 2026 cover the other half of the equation, our CPC study of 339 keywords covers Google click prices, and our Facebook ads cost study covers cost per lead. If you run Meta or Google ads in the US, UK, Canada or Australia and your CPM has jumped, give us read access to the account. A senior buyer will write a free audit of where the spend goes, whether your tracking counts real results, and the three things we would fix first. It takes about two working days and the document is yours. Our Meta ads management runs month to month with a named buyer. More studies are on our research page.
