Terms of Use
Last updated: September 2026
Educational estimates only
The calculators and content on this site are provided for general informational purposes. They produce estimates based on prices and usage limits published by the vendors at the time shown on each page. Vendors change prices, limits and plan names without notice, and actual usage varies. Nothing here is financial, purchasing or professional advice; confirm current pricing on the vendor's own site before you buy, and rely on your own usage dashboard for billing. We are not affiliated with any vendor named on the site.
No warranty
We work to keep the site accurate and current, but guidelines change and we may make mistakes. The site is provided "as is" without warranties of any kind. To the fullest extent permitted by law, we are not liable for any loss arising from use of the site or reliance on its results.
Acceptable use
You may use the calculators for personal, non-commercial purposes. Don't scrape, copy or republish the site's content or code without permission.
Third-party links
Links to research papers, government references and outside resources are provided for convenience. We're not responsible for their content.
