Every result rests on your own assumptions. OpenAI publishes no average cost per click, click-through rate or conversion rate, so the defaults are examples to replace, not benchmarks.
| Result | Formula |
|---|---|
| Clicks (CPC) | Budget ÷ cost per click |
| Clicks (CPM) | Budget ÷ CPM × 1,000 × CTR |
| Conversions | Clicks × conversion rate |
| Cost per conversion | (Budget + tool cost) ÷ conversions |
| ROAS | Revenue ÷ ad budget |
| Break-even CPA | Value per conversion × gross margin |
| Highest profitable CPC | Break-even CPA × conversion rate |
What OpenAI has actually said about pricing
- Auction: ads are sold in a relevance-weighted second-price auction. You set a maximum bid per ad group and often pay less.
- Starting bid: OpenAI suggests $3–$5 as a first maximum bid per click. The calculator’s examples of $2.50–$4.50 per click sit in the same range.
- Minimum daily budget: 25 USD, 15 EUR or 175 SEK depending on billing currency.
- Pacing: the daily budget is a seven-day average, and a single day can spend up to twice as much.
- CPM: trade press reported CPMs between $15 and $45 in spring 2026, down from $60 at launch. These are reported US figures, not an official price.

How to use the result
- Work out your break-even CPA before you pick a budget. It decides whether the channel can pay for itself.
- Choose a test budget that buys enough clicks to learn from, even if conversions stay few.
- Measure with UTM parameters and OpenAI’s pixel so you can replace assumptions with real numbers. The UTM builder and tracking guide show how.
- After a few weeks, enter your account’s real CPC and conversion rate, then copy the calculation link to share it.

How much does a click on a ChatGPT ad cost?
There is no fixed price. Ads are sold in an auction where you pay at most your bid, often less. OpenAI suggests starting with a maximum bid of $3–$5 per click, but that is a starting bid, not an average price. Use your own account’s numbers as soon as you have them.
How much budget do I need to test ChatGPT ads?
The minimum daily budget is 25 USD, 15 EUR or 175 SEK depending on your billing currency. That gets you started, but judging conversions usually takes enough budget for at least a few dozen of them. The calculator shows how many you can expect.
Do you pay per click or per impression?
Both exist. The Views objective is billed per thousand impressions (CPM) and Clicks per click (CPC). The Conversions objective optimises for conversions but is still billed per click or per impression, never per conversion.
Can one day cost more than the daily budget?
Yes. OpenAI treats the daily budget as an average over seven days. A single day can spend up to twice the daily budget, while the week stays within seven times the daily budget.
What is break-even CPA?
It is the most you can pay for a conversion without losing money: value per conversion multiplied by gross margin. Sell for $150 at a 40% margin and you break even at $60 per conversion.
Is ad spend included in the AthillyAds price?
No. Ad spend is paid directly to OpenAI. The first AthillyAds campaign is free and Pro costs $99 per ad account per month. Tick the box in the calculator to include it.
