AI Image Generation Cost Calculator

Calculate the cost of generating images with the major AI image APIs and compare them side by side. Pick a model and resolution, enter how many images you generate per month, and see the per-image and monthly cost. The comparison table re-prices every model at your volume so you can spot the cheapest option for your quality target. Runs entirely in your browser.

Prices are representative provider list rates per generated image and change often; token-billed models (GPT-image-1, Imagen) are shown at their approximate per-image cost. Use the override field or confirm current pricing with your provider before budgeting.

How to use the AI Image Generation Cost Calculator

Choose a model and resolution from the dropdown, then enter how many images you expect to generate each month. The result shows the per-image price and your projected monthly spend, and the comparison table re-prices every listed model at the same volume so you can see which is cheapest for a given quality tier. If your contract or a third-party host charges a different rate, type it into the override field.

Image APIs price in two ways: a flat fee per image (DALL·E, Flux, Imagen) or by output tokens that vary with resolution and quality (GPT-image-1). For the token-billed models the dropdown lists the approximate per-image cost at each quality level so you can compare on equal footing.

How AI image pricing works

Most image APIs bill a flat price per generated image that scales with resolution and quality. DALL·E 3, for example, charges more for HD than standard and more for wide or tall images than for squares; Flux has separate Pro, Dev, and Schnell tiers; and Imagen 3 uses a single per-image rate. Because the fee is per image regardless of prompt length, your cost is simply the price times the number of images you generate.

A newer approach prices images by output tokens. OpenAI's GPT-image-1 converts each generated image into a number of image tokens that depends on the resolution and the low/medium/high quality setting, then bills those tokens like text output. The practical effect is the same — a per-image cost — but it rises steeply with quality, so a high-quality 1024×1024 image can cost more than ten times a low-quality one. This tool lists the approximate per-image figure for each tier so you can budget without doing the token math yourself.

Subscription products such as Midjourney are not included here because they bill a flat monthly fee for a quota of generations rather than a per-image API rate, which is not directly comparable to usage-based pricing.

Common use cases

  • Budgeting a product feature. Project the monthly cost of an in-app image generator at your expected volume.
  • Choosing a provider. Compare DALL·E, Flux, Imagen, and Stable Diffusion at the same image count.
  • Quality vs cost. See how much jumping from standard to HD, or low to high quality, adds.
  • Self-host break-even. Compare flat API pricing against your own GPU cost per image.

Frequently asked questions

Why are GPT-image-1 prices approximate?
GPT-image-1 bills by image tokens, which depend on resolution and the low/medium/high quality setting rather than a single flat fee. The figures shown are the provider's approximate per-image costs for a square image at each quality tier; your exact cost depends on the size you request.

Does prompt length affect image cost?
For flat-rate models like DALL·E 3, Flux, and Imagen, no — you pay per generated image regardless of prompt length. For token-billed models the text prompt adds a small input-token cost on top of the image output cost, which is usually negligible next to the image itself.

Why is Midjourney not listed?
Midjourney bills a flat monthly subscription for a quota of generations rather than a usage-based per-image API rate, so it is not directly comparable to the pay-per-image pricing this calculator compares.

Are these the current prices?
They are representative provider list rates and change frequently. Use the override field to enter your actual rate, and confirm current pricing on the provider's page before relying on the estimate for a budget.

Can I generate images cheaper by self-hosting?
Open models like Stable Diffusion and Flux Schnell can be run on your own GPU, where the cost per image is the GPU time it takes. At high volume that can undercut API pricing; at low volume the API is usually cheaper because you pay nothing when idle.
