About MyStackCost
Last updated:
MyStackCost is a collection of free calculators that help teams estimate what their technology really costs: AI APIs, cloud infrastructure, SaaS subscriptions and even the meetings in their calendar.
How we build our calculators
- Transparent formulas. Every calculator explains exactly how the result is computed, with a worked example you can check by hand.
- Prices updated every day. AI model prices are checked automatically each day against OpenRouter’s public model list and cross-checked with LiteLLM’s open pricing file. Unusual changes are reviewed by a person before they are published, and every calculator links to the providers’ official pricing pages.
- Private by design. Calculations run entirely in your browser. We do not ask you to sign up, and we do not store the values you enter.
- Bilingual. Every calculator is available in English and Spanish, with examples adapted to each audience.
