Quick start
- Enter how many input tokens one request usually sends, including instructions, context, and the user message.
- Enter how many output tokens one response usually generates.
- Enter request count and the current input/output price per 1 million tokens from your provider.
Best uses
These are the situations this tool is meant for. If your task is close to one of these, the examples and notes below can help you choose the right inputs.
- Estimate the monthly cost of an AI support bot, writing helper, or internal tool.
- Compare two model price cards using the same token and request assumptions.
- Turn a token estimate into a rough budget before building a prototype.
- Explain why long prompts and long answers can cost different amounts.
What this calculator is solving
The AI Token Cost Calculator helps you do model-budget math without pretending any one price is permanent. You enter your own current input and output prices, then the calculator shows total cost and cost per request.
You do not need to memorize the formula first. Start by matching each input label on the calculator to the number, date, unit, or setting you actually have.
The formula in plain language
In plain language: The calculator multiplies tokens per request by request count, divides by 1,000,000, then multiplies input and output tokens by the prices you enter. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
If that sounds abstract, use the example cards on the calculator page. They show a complete set of inputs and the kind of answer you should expect.
How to read the answer
Read the headline result first. Then look at the smaller supporting lines because they explain the parts behind the answer, such as totals, units, ranges, or formula steps.
- Total cost is the estimated bill for the requests you entered.
- Input token cost and output token cost are split so you can see which side drives the budget.
- Cost per request is useful when comparing models or deciding whether a feature can scale.
Common mistakes to avoid
If the answer looks strange, the most likely cause is a small input mismatch: the wrong unit, date, weight, scale, mode, or policy assumption.
- Do not use old model prices from memory.
- Do not forget that long system prompts, retrieved context, and tool messages can be input tokens too.
- Do not assume cached tokens, batch discounts, free credits, taxes, or minimum charges are included.

FAQ in plain language
When should I use the AI Token Cost Calculator?
Use it when your task matches one of these common needs: Estimate the monthly cost of an AI support bot, writing helper, or internal tool. Compare two model price cards using the same token and request assumptions. It works best when you already know the values, dates, units, or settings the page asks for.
What is the AI Token Cost Calculator doing with my inputs?
In plain language: The calculator multiplies tokens per request by request count, divides by 1,000,000, then multiplies input and output tokens by the prices you enter. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
What do the main AI Token Cost Calculator inputs mean?
Input tokens: Tokens sent to the model, including instructions, prompt text, context, and tool messages. Output tokens: Tokens generated by the model in the response. Price per 1M tokens: The provider rate for one million tokens, entered separately for input and output.
How should I read the AI Token Cost Calculator answer?
Read the AI result as a best-effort clue or draft. Look at labels, scores, notes, and warnings together, then compare the result with the original text or image before using it anywhere important.
What should I double-check before trusting the answer?
AI providers can change prices, count cached tokens differently, or add plan rules. Use the current provider rate card for real budgets. Also check that you used the right unit, date, scale, or mode because small input changes can change the result.
Why does the calculator ask me to enter model prices?
Model prices change and different providers charge different rates for input, output, cached input, fine-tuned models, batch jobs, and special tools. Entering the rate yourself keeps the calculator useful without pretending one price is always current.
