Frequently asked questions
- How is the LLM API cost calculated?
- Input and output tokens are each priced per million tokens for the model you pick, summed per request, then multiplied by your monthly request volume. Prices come from our regularly-synced model catalog covering OpenAI, Anthropic, Google, Meta and hundreds more.
- Does this include my profit margin?
- The calculator shows your raw provider cost plus a sample 70% margin as a teaser. To set exact margins, VAT, payment fees and build customer-facing packages, open the full Calcaas app — your inputs carry over automatically.
- Is it really free and login-free?
- Yes. The cost calculator runs entirely in your browser with no account needed. You only sign in if you want to turn the cost into a priced product with packages, quotes and PDF exports.
