🖼️ AI Image Cost Calculator
What one generated image actually costs. Midjourney sells a subscription, so its real per-image price depends entirely on how many you make; Google and xAI charge per image, so the cost is fixed per picture. Those two models cross over at a volume worth knowing.
Subscription or per image: the volume where the answer flips
AI image tools are sold two different ways, and comparing them requires converting both to the same unit. Midjourney sells a monthly subscription with a pool of fast GPU time; Google and xAI sell images individually through an API. The subscription has a high floor and no ceiling; the API has no floor and no ceiling. Which is cheaper depends entirely on how many images you make.
Subscription cost per image = monthly fee / images actually generated
Where the lines cross
| Images a month | Midjourney each | Pay-per-image total |
|---|---|---|
| 10 | $3.00 | $0.20 |
| 50 | $0.60 | $1.00 |
| 100 | $0.30 | $2.00 |
| 300 | $0.10 | $6.00 |
| 1,500 | $0.02 | $30.00 |
| 5,000 | $0.006 | $100.00 |
The crossover against a $30 plan sits around 1,500 images a month. Below that, pay-per-image is cheaper; above it, the subscription is. Most individual users are nowhere near 1,500 and are paying ten to a hundred times the API rate per picture — which can still be the right choice, because they are also buying the interface, the community and the style.
What a subscription actually buys
Midjourney's plans are measured in fast GPU hours rather than images, because generation time varies with model and settings. Basic includes 3.3 hours a month, which is roughly 200 images and no relax mode — when the hours run out, you stop. Standard at $30 adds unlimited relax generations, which is the detail that changes everything: if you are willing to wait, the marginal cost of an image falls to zero.
That makes Standard the plan where per-image cost can approach nothing, and Basic the plan where it is capped by the hours. Annual billing takes 20% off across the range, so Standard becomes $24 a month if you commit for a year.
Fast GPU hours are an estimate of images, not a count. How many pictures an hour buys depends on the model version, resolution and whether you are upscaling. The figures here convert published hours at a typical rate and should be treated as approximate.
API image pricing is more predictable
Google and xAI charge per generated image, with the price varying by resolution rather than by time. Grok Imagine starts at $0.02 for 1K or 2K; Google's Flash Image runs about $0.045 at 0.5K rising to $0.151 at 4K. There is no subscription, no monthly floor, and the hundredth image costs exactly what the first did.
Video is priced per second rather than per image: Grok Imagine Video at $0.02 a second makes a ten-second clip about $0.20, and Gemini Omni Flash prices video output per token at roughly $0.10 per second of 720p — five times the price for a different pipeline. Video is the area where the gap between providers is widest and where checking before committing matters most.
A worked example
A designer makes about 300 images a month. On Midjourney Standard that is $30, or $0.10 each; on annual billing, $24 and $0.08 each. Through Grok Imagine at $0.02 it would be $6. The API is five times cheaper on raw generation, and the designer stays on Midjourney anyway because the interface, the variation tools and the aesthetic are what they are actually paying for. That is a legitimate answer — but it is worth knowing it costs $24 a month.
The natural follow-ups are the llm pricing comparison, for what this figure feeds into, and the ai token calculator, for the closely related case.
Frequently Asked Questions (FAQs)
How much does one Midjourney image cost?
It depends entirely on volume, because you buy a subscription rather than images. On the $30 Standard plan, 300 images a month works out at $0.10 each; 1,500 images makes it $0.02 each; 50 images makes it $0.60 each.
Is Midjourney or an API cheaper?
Below roughly 1,500 images a month, a pay-per-image API at $0.02 is cheaper. Above that, the subscription wins. Most individual users are well below the crossover and are paying considerably more per image than an API would charge.
What do Midjourney's fast GPU hours mean?
Generation time rather than a number of images. Basic includes 3.3 hours, roughly 200 images; Standard includes 15 hours plus unlimited slower relax generations, which is why its effective per-image cost can approach zero.
Is annual billing worth it?
It is 20% cheaper: Standard drops from $30 to $24 a month. The trade is a year's commitment, which is only worth it if your usage is steady rather than project-based.
How much does AI video cost?
Grok Imagine Video is about $0.02 per second, so ten seconds is roughly $0.20. Gemini Omni Flash prices video output per token at around $0.10 per second of 720p. Video pricing varies more between providers than image pricing does.
Why are image prices quoted by resolution?
Because larger images take more computation. Google's Flash Image runs from about $0.045 at 0.5K to $0.151 at 4K, so generating at the resolution you actually need rather than the maximum available is a straightforward saving.
Are these prices current?
Midjourney plans and the API rates were checked on 2026-10-26. Image generation pricing changes frequently as models are replaced, so confirm with the provider before planning around these figures.
