FAQ
Which AI cost calculator should I use?
Use the All-in-One AI Cost Calculator to compare all providers side by side. If you know your provider, use the dedicated calculator for more detailed model comparisons.
Are these calculators free?
Yes. All calculators are free browser-based tools. No signup, no API key, no data sent to servers.
How accurate are the cost estimates?
Estimates are based on reference pricing per 1M tokens. Actual costs may vary due to caching, batch discounts, and provider pricing changes. Always verify current pricing before budgeting.
What is a token in LLM pricing?
A token is a unit of text processed by the model. In English, one token is roughly 3-4 characters. Input tokens are your prompt; output tokens are the model's response.
How do I reduce AI API costs?
Trim prompts, cache repeated responses, route simple tasks to cheaper models, limit max output tokens, and monitor daily request volume.
Do these calculators call AI APIs?
No. These are static browser calculators. They do not call any API, require an API key, or upload your data.
