ChatGPT Ads Cost UK: What You Actually Pay in 2026, With a Budget Estimator
Most pages about what ChatGPT Ads cost repeat the same two numbers, $3 to $5 a click and a $60 CPM, without saying where they came from or how old they are. Some of it traces back to OpenAI. Some of it is a launch-era press figure that has been copied ever since. This page separates the two, converts what matters into pounds, and adds the one thing a UK advertiser cannot get from a US guide: what the Ads Manager actually shows on a UK account.
If you want the wider picture first, our ChatGPT Ads guide covers how the platform works and whether it is worth testing. If you would rather someone ran the test for you, that is our ChatGPT ads agency service.

How ChatGPT Ads pricing works
You do not buy ChatGPT Ads at a fixed rate. Every time an ad could appear, eligible ads compete in an auction. OpenAI's help centre puts it in one line: the final winning auction bid sets the price you pay. Your job is to choose three things, and the auction does the rest.
| You choose | Where | What it controls |
|---|---|---|
| Campaign objective | Campaign | What you are billed for: views, clicks, or clicks and views optimised towards conversions |
| Daily or total budget | Campaign | The most the campaign can spend |
| Bid strategy | Ad group | Whether you set a target cost or let OpenAI bid for you |
The objective decides the billing event:
| Objective | You pay for | Good for |
|---|---|---|
| Views (also called Reach in parts of the help centre) | Every 1,000 impressions (CPM) | Awareness |
| Clicks | Each click (CPC) | Traffic and a first test |
| Conversions | Clicks or impressions, optimised towards a conversion event | Leads and sales, once tracking works |
One point catches people out. A Conversions campaign is not billed per lead or per sale. OpenAI is explicit that ads are not billed per conversion. You still pay for clicks or impressions, and the system tries to find the ones most likely to convert.
The bidding options, as of November 2026
The bidding menu changed two days before this page was written, so anything older than 9 November 2026 describes the previous system.
- Intelligent bidding. Formerly called Maximize Results or Autobid. You set a budget and OpenAI sets the bids.
- Target CPC, for click campaigns. You name the average cost per click you would like. Individual clicks can cost more or less.
- Target CPA, for conversion campaigns. You name the average cost per conversion you would like.
- Max CPC and Max Bid. The older hard caps. Existing campaigns keep them until 1 January 2027, then they go.
The important word in the new options is average. A target is a goal the system works towards. It is not a ceiling, and OpenAI says plainly that your actual average cost may be higher or lower than the target you set.
What OpenAI's own documentation says about cost
Everything in this table comes from OpenAI's help centre or developer documentation, read on 11 November 2026. Dollar figures are converted at £0.7515 to the dollar, the European Central Bank reference rate for that day, and are rounded.
| Question | What OpenAI says | In pounds |
|---|---|---|
| Is there a rate card? | No. Prices are set by auction | n/a |
| Minimum daily budget, GBP account | 15 GBP | £15 |
| Minimum daily budget, USD account | 25 USD | About £18.79 |
| Suggested starting bid, click campaigns | A maximum bid of $3 to $5 a click | About £2.25 to £3.76 |
| Suggested bid, conversion campaigns | No recommended bid amount at this time | n/a |
| Most a single day can bill | Twice your daily budget | £30 on a £15 budget |
| Most a budget week can bill | Seven times your daily budget | £105 on a £15 budget |
| When you are charged | In arrears, at your payment threshold and at month end | Our UK threshold is £25 |
| Whether tax is included | No. Taxes are added on top of spend | Our £25 threshold was invoiced at £30.00, which matches 20% UK VAT |
| Refunds | Valid delivered spend is generally not refundable | n/a |
| After you pause | Ads can keep serving, and billing, for up to 24 hours | n/a |
Two of those rows deserve a second look.
The £15 minimum is per campaign, per day. It is a floor on the budget you can type in, not a commitment. Run one campaign at the minimum for a 30 day month and the most it can spend is £450. You can pause it on day three.
The $3 to $5 figure is a suggested bid. It appears in OpenAI's "Ads in ChatGPT: The Basics" article as a recommended starting maximum bid for click campaigns. A bid is the most you are willing to pay, and an auction usually clears below it. Treating it as the price of a click overstates the cost, as our own numbers below show.
Where the public reports disagree
These are the figures you will meet elsewhere, with who published them and when. We have quoted each publisher's own claim and have not tested it.
| Claim | Publisher and date | How it squares with OpenAI |
|---|---|---|
| Clicks cost $3 to $5 | Stacker and WebFX, 24 June 2026; Top Growth Marketing, updated 30 October 2026 | OpenAI gives $3 to $5 as a suggested maximum bid, not a cost |
| Finance, legal and SaaS clicks run $8 to $25 | Top Growth Marketing, updated 30 October 2026 | OpenAI publishes no prices by industry |
| CPMs run $25 to $60 | Top Growth Marketing, updated 30 October 2026 | No CPM range in OpenAI's help centre. Its developer page uses a $60 CPM as a worked example |
| $60 is the default maximum CPM bid | Stacker and WebFX, 24 June 2026 | We could not confirm a default in the pages we read |
| $60 was a launch figure, and CPMs were reported near $25 by April | eSEOspace, reviewed 8 November 2026 | Consistent with a price that has fallen since launch, but not an OpenAI figure |
| About $1.72 a click on a real account | Opascope, 15 June 2026, one account over 15 days | A measured result, well below the suggested bid |
The pattern is consistent once you see it. The high numbers are bids and launch-era list prices. The low numbers are what individual advertisers measured after the fact. Neither is wrong, but only one of them is a cost.
A second conflict is about minimums. You will still find pages quoting a $50,000 or $200,000 entry price. Those were the managed pilot deals from early 2026. They do not apply to the self-serve Ads Manager that UK businesses have used since June.
What we paid: one small UK test
We ran a short test on our own Ads Manager account in August 2026, promoting a free audit to UK businesses. It is a small sample and we are showing it because it is real, not because it proves anything.
| Measure | Our test |
|---|---|
| Spend | £27.08 |
| Impressions | 4,563 |
| Clicks | 20 |
| Average cost per click | £1.35 |
| Click-through rate | 0.44% |
| Cost per 1,000 impressions | £5.93 |
What it does tell you: a UK click campaign can clear well under OpenAI's suggested bid. At the time of writing, the same account shows a £2.60 maximum bid rated "Strong delivery" by the Ads Manager's own bid guidance, which is the lower half of the suggested range.
What it does not tell you: anything about cost per lead. Twenty clicks is not enough to measure a conversion rate, and the account had no conversion events recorded. It is one advertiser, one offer and two days. Please do not plan a budget on our £1.35.
ChatGPT Ads budget estimator
The estimator below turns a daily budget and a bid into a range. It gives a range on purpose. A single number would claim a precision that nobody outside OpenAI has.
Assumptions behind the range
How to use it well:
- Start with the bid you would actually set. £2.50 is the default because it sits inside OpenAI's suggested range once converted to pounds.
- Use your own conversion rate. Take it from the landing page you plan to use, measured on paid traffic if you have it. People arriving from ChatGPT are often earlier in their decision than people arriving from a search, so a rate borrowed from brand search will flatter the result.
- Open the assumptions. Price drift and click rate are the two things that move the answer most. The defaults are ours. Replace them with your own figures after the first fortnight.
As a worked example, the defaults describe a £30 a day test over 30 days with a £2.50 target. That is a planned £900, somewhere between 290 and 480 clicks, and 6 to 10 leads at a 2% conversion rate, or roughly £94 to £156 a lead. If that cost per lead would not make you money, a bigger budget will not fix it. A better landing page or a different channel might.
What a first UK test really costs
The media budget is the visible cost. Three others decide whether the test teaches you anything.
- Time to learn. We suggest judging a campaign after two to three weeks, not two to three days. At the £15 minimum that is roughly £210 to £315 before you draw a conclusion.
- Setup. Account verification, a billing profile, the OpenAI pixel and at least one conversion event. None of it costs money, but a test without tracking only tells you what a click costs.
- Management. Your own hours, or an agency's fee.
On agency fees, very few UK agencies publish a price for ChatGPT Ads, so there is no reliable UK average to quote. Two US providers do publish theirs. On 11 November 2026, WebFX's pricing table listed a $750 a month management tier, covering several ad networks including ChatGPT, for up to $5,000 of monthly ad spend (its own FAQ on the same page says from $3,000 a month), and AppLabx listed an entry tier of $500 a month plus 30% of ad spend. Both follow the usual paid media models: a flat retainer, a percentage of spend, or a mix. Expect UK quotes to follow the same shape. Ours is a flat £500 a month retainer, with your ad spend paid directly to OpenAI on top. What it covers is on the ChatGPT ads agency page.
One way to cut the cost: ChatGPT Business ad credits
If you already pay for a ChatGPT Business workspace with a UK billing address, the workspace owner can claim ad credits worth up to $50 a month, which is about £37.58, until 31 January 2027. The credit matches your seat fees up to that cap and each month's credit expires 30 days after it is issued. It will not fund a campaign on its own, but it takes a little off a first test. The offer cannot be combined with a sign-up promotion on the same ad account.
Is it cheaper than Google Ads or Meta?
There is not enough public data to answer that honestly, and anyone who gives you a confident number is guessing. Cost per click is also the wrong comparison. A cheap click from someone who is still researching can be worth less than an expensive click from someone ready to buy.
Compare on what you sell. Send the same offer to the same landing page from each channel, track the same conversion, and read cost per qualified lead or cost per sale after three weeks. Our guide has a fuller comparison of ChatGPT Ads with Google Ads and Meta.

Frequently Asked Questions
ChatGPT Ads cost FAQs
How much do ChatGPT ads cost in the UK?
There is no price list. ChatGPT Ads are sold by auction, so you choose a daily budget and a bid or target and the auction decides what you pay. The smallest daily budget OpenAI allows on an account billed in pounds is £15, according to its help centre on 11 November 2026. OpenAI recommends starting click campaigns with a maximum bid of $3 to $5 a click, which is about £2.25 to £3.76 at the 11 November 2026 exchange rate. That is a suggested bid, not the price you will pay. On our own small UK test in August 2026 the average was £1.35 a click.
Is there a minimum spend for ChatGPT ads?
There is no minimum commitment or contract for self-serve advertisers, but there is a minimum daily budget per campaign. OpenAI's help centre lists it by billing currency: £15 for GBP, 15 euros for EUR and $25 for USD, as read on 11 November 2026. You can pause or stop a campaign at any time, so the minimum is a daily floor and not a monthly obligation.
Do you pay per click or per impression on ChatGPT?
Either, depending on the campaign objective. A Views campaign is billed per thousand impressions (CPM). A Clicks campaign is billed per click (CPC). A Conversions campaign optimises towards a conversion event but is still billed for clicks or impressions. OpenAI states that ads are not billed per conversion.
How does OpenAI bill UK advertisers?
Self-serve accounts are postpaid by card. Spend builds up and your card is charged when the balance reaches your account's payment threshold, and again at the end of the month for anything outstanding. Our UK account is billed in pounds with a £25 threshold. The currency, country and time zone of an ad account cannot be changed after it is created, so check them before you finish signing up.
Can my daily spend go over my daily budget?
Yes. OpenAI treats a daily budget as an average over a seven day budget week that runs Sunday to Saturday. A single day can bill up to twice the daily budget, and the week as a whole will not bill more than seven times it. On a £30 daily budget that means up to £60 on one day and no more than £210 across the week.
Are ChatGPT ads cheaper than Google Ads?
Nobody can say reliably yet. OpenAI publishes no average prices, the public reports conflict, and the samples behind them are small. Our own UK test paid £1.35 a click, but that was 20 clicks over about two days, which is far too little to compare with a mature Google Ads account. The fair test is your own: run both against the same offer and compare cost per qualified lead or sale, not cost per click.
Do ChatGPT ads prices include VAT?
No. Budgets, bids and the spend shown in Ads Manager exclude tax, and OpenAI's billing page says applicable taxes are added on top of your charges. On our own UK account the £25 payment threshold was invoiced at £30.00, and £27.08 of ad spend was invoiced at £32.48 in total, which is what 20% UK VAT on top looks like. You can add a VAT number in Ads Manager under Billing, then Settings. If you cannot reclaim VAT, add a fifth to every figure on this page, and ask your accountant how to treat the invoices.
