AI Image Generation Cost Calculator
Use this calculator to estimate how much AI image generation will cost before you commit budget. Enter how many images you plan to create, roughly how many tokens each image will use, and the price per 1,000 tokens from your provider. The tool then gives you a quick project cost estimate so you can plan art pipelines, campaigns, or client work with fewer surprises.
How the AI image cost formula works
Many AI image models charge based on tokens. A token is a small chunk of text from your prompt and, in some systems, from the model’s internal reasoning. The more descriptive or complex the prompt, the more tokens it typically consumes.
This calculator assumes three main inputs:
- N – the number of images you plan to generate
- T – the average tokens used per image
- P – the price in dollars per 1,000 tokens
The cost in dollars is calculated as:
Cost = N × T × P / 1000
In words: you multiply images by tokens per image to get the total tokens, convert that total to “thousands of tokens,” then multiply by your provider’s price per 1,000 tokens.
Formula in MathML
The same relationship can be expressed more formally as:
Where C is the estimated cost in dollars, N is the number of images, T is tokens per image, and P is the price per 1,000 tokens in dollars.
Interpreting your results
When you click the estimate button, the calculator returns a single dollar amount. Use this value as a planning guide, not an exact invoice. It helps you answer questions such as:
- What is the approximate cost for a single batch of images?
- How does cost change if I increase image count or prompt complexity?
- Which provider or model tier fits my budget for this project?
If the number seems higher than expected, you can:
- Reduce the number of images in early exploration rounds
- Simplify prompts to lower tokens per image
- Switch to a cheaper tier or look for subscription credits
Worked example: character portraits for a game
Imagine you are creating character art for an indie game. You want detailed portraits for 50 characters and you know from past use that your prompts use about 750 tokens per image. Your provider charges $0.020 per 1,000 tokens.
- N (images) = 50
- T (tokens per image) = 750
- P (price per 1,000 tokens) = 0.020
Total tokens used:
50 images × 750 tokens = 37,500 tokens
Tokens in thousands:
37,500 / 1000 = 37.5 units of 1,000 tokens
Multiply by the price per 1,000 tokens:
37.5 × $0.020 = $0.75
Under these assumptions, generating all 50 portraits would cost about $0.75. If you expect to iterate three times on each character, multiply by three to get an approximate total art budget for this part of the project.
Sample scenarios at a glance
The table below shows how the same formula behaves for different project sizes and prompt complexities, all using a price of $0.020 per 1,000 tokens.
| Scenario | Images (N) | Tokens / image (T) | Price per 1K tokens (P) | Estimated cost (C) |
|---|---|---|---|---|
| Simple social media icons | 20 | 400 | $0.020 | $0.16 |
| Detailed product shots | 80 | 800 | $0.020 | $1.28 |
| Complex marketing scenes | 150 | 1,100 | $0.020 | $3.30 |
You can plug these example numbers into the calculator to see how changing any one input affects the final budget.
Choosing a tokens-per-image value
If you are not sure how many tokens your prompts will use, you can start with approximate ranges based on prompt complexity. Actual values depend on your wording and the provider, but these guidelines can help you pick a starting point for the calculator.
| Prompt type | Typical token range | When to use |
|---|---|---|
| Very short prompt | 200–400 tokens | Quick sketches, thumbnails, or exploratory ideas |
| Detailed portrait prompt | 600–900 tokens | Character art, avatars, marketing headshots |
| Complex scene description | 900–1,300 tokens | Story scenes, multi-subject images, rich environments |
Many platforms provide a live token counter or show token usage in logs after generation. Use those numbers to refine the “tokens per image” field over time.
Comparing AI image providers
Different AI image providers and model tiers can vary significantly in price and token behavior. Some charge purely per 1,000 tokens; others bundle a certain number of image credits into a subscription and then bill extra usage separately.
The table below summarizes how the same project might look across three simplified provider styles. These are not real prices, but they illustrate how to think about cost structures.
| Provider style | Pricing model | Impact on calculator inputs |
|---|---|---|
| Pure token billing | Flat $ per 1,000 tokens | Use your exact per-1K token price as P; base fees are usually zero. |
| Subscription + overage | Monthly fee includes some usage, then per-1K token charges | Use the overage rate as P, and treat the subscription fee as a separate fixed cost. |
| Image credit packs | Pay for a bundle of images instead of tokens | The calculator is less direct. You can estimate an implied per-1K token price by dividing the pack cost by total tokens included. |
For a deeper understanding of tokens more generally, you may also want to use a dedicated token cost or text token calculator if your workflow includes prompts, captions, or other text-heavy operations.
Assumptions and limitations
This tool is designed for quick budgeting. It deliberately simplifies several real-world details so you can get an immediate sense of scale. Keep the following assumptions and limitations in mind when interpreting the result:
- Constant tokens per image: The formula assumes each image uses the same number of tokens. In practice, some prompts will be shorter or longer, so your actual token total may differ.
- Price per 1,000 tokens only: The calculator focuses on token-based pricing. It does not automatically include account subscriptions, minimum monthly spend, or one-time setup fees.
- No model tier adjustments: Some providers charge different rates for basic versus advanced models or for higher resolutions. To approximate these, you can increase or decrease the price per 1,000 tokens field.
- Extra features are excluded: Features such as upscaling, style transfer, control tools, or inpainting may have separate costs or additional token usage. These need to be added manually to your budget.
- Token limits and quotas: Daily token limits, rate caps, or project-level quotas affect timing rather than the cost formula. You may need to spread large projects across several days even if the total cost is acceptable.
- Provider-specific details: Each provider defines tokens, credits, and billing slightly differently. Always confirm the latest pricing and policies before treating calculator results as a firm quote.
Planning budgets for larger projects
For large-scale image production, you can use the same calculator iteratively to budget distinct phases of your workflow. A common approach is to:
- Generate low-resolution concept images in bulk
- Down-select favorites
- Allocate more tokens and higher resolution only to final candidates
For example, you might plan 500 low-detail concept images at 400 tokens each, then 100 high-detail finals at 1,200 tokens each. Estimate the cost of each phase separately and add them together to get a more realistic picture of total spend.
Frequently asked questions
How accurate is this AI image cost estimate?
The estimate is usually accurate to the right order of magnitude, but it will not match your bill exactly. Variations in prompt length, retries, model changes, and provider fees can all shift the final cost up or down. Treat the calculator as a planning tool, not a billing system.
How do I include subscription fees or base charges?
Run the calculator as usual using your per-1,000 token rate. Then add any fixed subscription or base fees on top of the result. If a subscription includes some tokens for free, subtract the value of those tokens from your estimated usage before applying the formula.
Can I use this calculator with any AI image provider?
Yes, as long as you can express the provider’s pricing in terms of cost per 1,000 tokens or a close equivalent. When providers use image credits instead of tokens, you can back into an approximate per-1,000 token price by dividing the pack cost by the implied number of tokens used.
What if my tokens per image vary a lot?
In that case, use an average. Take a handful of representative prompts, check how many tokens they use, and compute the mean value. Enter that average as your tokens-per-image input. If you want a conservative budget, add a small buffer on top, such as 10–20 percent.
Does this include moderation failures or rejected images?
Some platforms bill tokens even when images are rejected due to policy violations. Others do not. Because these rules differ, the calculator does not attempt to model them. Always design prompts that comply with your provider’s policies to avoid wasting tokens.
