AI Cost Calculator

Estimate what a task or team will cost per month across AI models.

What AI Cost Calculator does

Enter your words per prompt, words per response, runs per day, and which model you use, and get a monthly cost estimate for that AI workflow. It's built for anyone budgeting an AI feature or a team habit, comparing a chatbot subscription against calling the API directly before committing to either. Unlike paid token calculators, there's no signup, and you can rerun the numbers for a different model in seconds.

How it works

  1. Enter your words per prompt, words per response, and how many times you run it per day.
  2. Pick the AI model you use, or want to compare, from the dropdown.
  3. See your estimated monthly cost, broken out so you can compare it against a different model or plan.

  • A developer sanity checking a client quote before committing to a fixed monthly AI budget.

Frequently asked questions

Is this free and do I need to log in?

Yes, it is free with no login. Fill in your usage numbers and get the estimate immediately.

How accurate is the estimate?

It's a close approximation based on average word to token ratios and published pricing, so real bills vary a bit depending on your exact prompts and any system instructions. Treat it as a planning number, not an invoice level figure.

Are these prices current, or just estimates?

Model API prices change often, so the numbers here reflect published rates at the time of writing and are meant as a reasonable estimate, not a live quote. Check the provider's own pricing page before finalizing a large budget.

Can I use these numbers in a client proposal or internal budget?

Yes, the estimate is yours to reuse in a proposal, budget doc, or business case. Just label it as an estimate, since actual usage and provider pricing can shift.

Is my usage data stored anywhere?

No account is created, so your inputs are used only to calculate the estimate you see on screen and are not saved to a profile.
