ChatGPT Ads Cost & Pricing: CPMs, Minimums, and What to Budget

ChatGPT ads cost a minimum of $25 a day, OpenAI recommends a $3 to $5 starting bid per click, and reported CPMs have fallen from $60 at launch to $15 to $45 in the open auction. There is no account-level minimum, no setup fee, and OpenAI bills after delivery. New to the channel? Start with the complete guide to ChatGPT ads; this post covers cost only.

Last updated September 13, 2026. OpenAI publishes no rate card; every figure below is from OpenAI's Help Center, trade press or a named advertiser, and labelled as such.

How much do ChatGPT ads cost?

A working number: $750 a month, the $25 floor for 30 days, buys roughly 190 clicks at a $4 CPC. The figures in circulation come in three layers:

• What OpenAI publishes. The $25 floor, the $3 to $5 CPC bid, the 2x daily and 7x weekly caps and the postpay rules (Help Center). Ads Manager also pre-fills a $60 maximum CPM bid on Views campaigns (Choice Marketing, WebFX), a ceiling, not a price.
• What the press reports. A $60 CPM and a $200,000 commitment at launch (The Information, January 2026); $25 to $45 by April, with a $15 low via Ad Age (Digiday). Managed-buy rates, not a rate card.
• What practitioners report. Average CPCs from $3.14 (Workshop Digital) to about $9 (Symphonic Digital), $7 in the test Adweek covered, and $8 to $18 in software and finance, vendor-reported by Cloro. The bid field takes $0.01 to $100, placeholder $3.00 (r/PPC).

How much does ChatGPT advertising cost?

ChatGPT advertising cost starts at a $25 daily budget and is billed on the objective you pick, so ChatGPT ads pricing is a CPM on Views and a CPC on Clicks rather than one rate card. OpenAI ads pricing publishes no floor CPM; the ChatGPT ads minimum spend is the daily budget alone, with no account minimum and no platform fee. The rest of this post breaks each of those down.

How pricing works: auction, CPM, CPC, oCPC

Every ad is sold in a second-price auction weighted by relevance (Help Center): you set a maximum bid per ad group and pay just enough to beat the next eligible ad, so a relevant ad with a low bid can beat an irrelevant one with a high bid.

What you pay for depends on the objective, which is locked at creation. Views bills per 1,000 impressions (CPM); older docs and the live Ads Manager still call it "Reach". Clicks bills per valid click, with OpenAI's only bid guidance: "we recommend starting with a maximum bid of $3 to $5 USD per click." Conversions bills per click (oCPC) or per impression (oCPM), never per conversion, toward one standard event, and has no recommended bid.

Maximize results, the default for eligible new ad groups, sets bids within a daily budget and "does not guarantee delivery against a specific CPA, CPC, ROAS, or other cost-efficiency target at this time" (Help Center). Manual: Max bid gives a hard ceiling.

Minimum spend and daily budgets by currency

There is no account-level minimum spend published anywhere. The only floor is per campaign per day, by billing currency. All 21 (Help Center, updated September 2026):

India is the cheapest entry: ₹725 a day is about $7.60 (TechCrunch, August 27, 2026).

Pacing math: what $25 a day actually allows

A daily budget is "the average amount you want the campaign to spend per day over a seven day period," not a cap. Daily spend "will not exceed twice" the daily budget and seven-day spend "will not exceed seven times" it (Help Center). Worked through:

• $25 a day. Any single day can reach $50; any rolling seven days cannot pass $175.
• $100 a day. Up to $200 in a day and $700 across seven, OpenAI’s own example (Daily Budgets).
• Budget must cover the bid. The daily budget cannot be set below the effective ad-group bid; OpenAI’s example is a $250.50 bid blocking any budget under $250.50. At a $3 to $5 CPC this never binds.
• Campaign-total budgets pace over the schedule instead, to 365 days, or 60 with no end date (Budget Pacing).

Billing: postpay, thresholds and the card hold

ChatGPT Ads "currently uses a postpay billing model that charges advertisers after ads have been delivered" (Help Center). The payment threshold, $25 in OpenAI's example, starts around there, rises automatically and cannot be changed manually; the card is charged each time unpaid spend reaches it. Adding a card may show a temporary $50 or $100 authorization hold for up to 7 days.

How the CPM went from $60 to $25

Each row is a dated report, not an OpenAI rate card.

Read it as a supply story: in February one advertiser spent $2,500 of a $250,000 commitment in four weeks (Digiday); as inventory opened and CPC bidding let smaller buyers in, the clearing price fell.

ChatGPT vs Google, Meta, LinkedIn, TikTok CPM and CPC

The full head-to-head is in ChatGPT ads vs Google Ads; this is the cost slice.

On the Google CPM. WordStream's 2026 report publishes no CPM, so any Google Search CPM is derived. CPC times CTR ($5.42 times 6.64%) gives about $360 per 1,000 impressions, which mostly shows CPM is the wrong unit for a channel where 1 in 15 impressions is a click; a ~$38 figure circulates in trade press with no stated method. On ChatGPT, at the 0.91% advertiser-reported CTR (EMARKETER), a $4 CPC implies an effective CPM near $36. Compare on cost per click and cost per outcome.

What to budget for a test

Three scenarios on the Clicks objective. Assumptions: a $4 CPC, the middle of OpenAI's guidance; impressions back-calculated at 0.91% CTR (advertiser-reported, EMARKETER) and 0.6% (the agency test Adweek reported); conversions at 2% to 6%, the vendor-reported band from Lapis. On CPC billing a lower CTR means more impressions for the same money, not fewer clicks.

The floor test shows whether the channel delivers; 4 to 11 conversions say little about CPA. The readable test is where conversion rate stops being noise, and with the $500 credit it costs $1,000 out of pocket. The third row matches Stream's spend per test group in its OpenAI case study (about $10,000, June 5 to August 5, 2026). Use a daily budget rather than a campaign total; an agency three weeks in found lifetime pacing poor and daily fine (r/PPC).

What makes ChatGPT ads cheaper or more expensive

The auction is second-price and relevance-weighted, so most of your cost is decided before the bid:

• Relevance. Ad selection weighs the conversation, landing page, title, copy and context hints (Help Center).
• Context hints. Free text, not keywords, not exact-match. Workshop Digital found keyword-style hints beat conversational phrasing, 1.2% CTR against 0.9% (Workshop Digital).
• Bid strategy. Maximize results chases volume with no cost target; a manual max bid caps the click price but "low bids can still limit delivery" (Budget Pacing).
• Vertical. Retail and ecommerce clear at the low end; software and finance at $8 to $18 (Cloro, vendor-reported).
• Competition. Symphonic Digital started at $3 and watched its max bid climb to about $12 (Symphonic Digital).
• Creative. Jotform attributes a 65% CTR lift to creative work across more than 100 optimizations (OpenAI case study). What is running now is in the ChatGPT ads library.

Is it worth it?

OpenAI's answer is four customer stories, advertiser-measured:

• Newegg (product feed ads): 3x ROAS over 28 days and 7x during its two-week Fantastech Sale (OpenAI, August 17, 2026).
• Stream: about 2x ROAS (OpenAI, September 1, 2026).
• Jotform: 60% lower cost per signup than paid social and 30% lower than paid search (OpenAI, September 3, 2026).
• LegalNature: about 40% of ad visitors started the document flow immediately, last-click (OpenAI, September 3, 2026).

The other side: Adweek collected tests where the economics did not work: Choice OMG spent $415 for about 9,000 impressions, a 0.6% CTR, and zero conversions from 60 clicks at $7 each (Adweek via Yahoo Finance, August 2026). PPC Land reported Walmart's direct ChatGPT sales converting at a rate 3x lower than its website traffic (PPC Land, February 2026). Against that, Criteo measured LLM-referred users converting about 1.5x higher than other referral channels (Criteo, March 2026).

The pattern: cost per click is low and stable, cost per outcome is wide open, and OpenAI's own FAQ says the platform "does not yet have performance benchmarks across advertisers, industries, or campaign types" (Help Center). Budget for the readable test, instrument it, and decide on your numbers.

That is the job Sprites is built for: run the ChatGPT test alongside your Google and Meta campaigns, measure all three on the same cost-per-outcome basis, and optimize across them from one place. Get started self-serve, or book a demo.

Frequently asked questions

How much does ChatGPT advertising cost?

ChatGPT advertising cost starts at a $25 daily budget and is billed on the objective you pick, so ChatGPT ads pricing is a CPM on Views and a CPC on Clicks rather than one rate card. OpenAI ads pricing publishes no floor CPM; the ChatGPT ads minimum spend is the daily budget alone, with no account minimum and no platform fee.

What is the minimum spend for ChatGPT ads?

A daily campaign budget: $25 in the US, 15 in euros or pounds, 725 rupees in India, plus 18 more above. There is no account-level minimum. The $200,000 and $50,000 minimums applied to the managed pilot and ended May 5, 2026.

How much is a ChatGPT ads CPM?

OpenAI does not publish one. The Information reported $60 at launch in February 2026; by April, Digiday reported $25 to $45, with a $15 low cited by Ad Age. Ads Manager still pre-fills a $60 maximum CPM bid, a ceiling rather than a price.

What CPC should I bid on ChatGPT ads?

OpenAI recommends a starting maximum bid of $3 to $5 per click. Practitioner writeups report average CPCs of about $3 to $9, and a vendor roundup puts software and finance at $8 to $18.

Do ChatGPT ads charge per click or per impression?

Both, by objective. Views bills per 1,000 impressions (CPM), Clicks per valid click (CPC), and Conversions per click (oCPC) or per impression (oCPM), never per conversion. The objective is locked once the campaign is created.

How does ChatGPT ads billing work?

Postpay by credit card. OpenAI assigns a payment threshold, starting around $25, and charges the card each time unpaid spend reaches it; the threshold rises automatically. Adding a card can trigger a temporary $50 or $100 authorization hold for up to 7 days.

Are ChatGPT ads cheaper than Google Ads?

Per click, often yes: the $3 to $5 recommended bid sits below WordStream’s $5.42 average Google Search CPC. Per outcome, the evidence is mixed: CTR runs about 0.9% against 6.64% on Google Search, some agencies report zero conversions, and OpenAI’s case studies report 2x to 3x ROAS.
