Terms of Service
By using Stamp Calculator, you agree to these terms. If you do not agree, please do not use the site.
The service
Stamp Calculator provides free online tools and articles to help you estimate how many stamps or how much postage may be needed for common domestic letter scenarios. The site is offered as a convenience for personal and small-business planning.
Provided “as is”
The site and all content are provided “as is” and “as available.” We do not promise that the site will always be online, error-free, or free of harmful code. We may change, suspend, or discontinue features at any time without notice.
No guarantee of accuracy
Postage rules, rates, and classifications change. Our calculators and explanations are based on information we believe is accurate at the time of writing, but we offer no guarantee of accuracy for any specific piece of mail, rate, or USPS decision. Results are estimates for planning only.
You are responsible for verifying postage before mailing. Weigh your item, check current USPS rules, and confirm at usps.com or with a postal clerk when the mail is important, valuable, or time-sensitive.
No affiliation
Stamp Calculator is not affiliated with, endorsed by, or sponsored by the United States Postal Service or any other carrier. USPS is a registered trademark of the United States Postal Service.
Limitation of liability
To the fullest extent permitted by law, we are not liable for any direct, indirect, incidental, consequential, or special damages arising from your use of the site, reliance on any estimate, or errors or omissions in content—including lost mail fees, returned mail, late delivery, or business losses. Your sole remedy for dissatisfaction with the site is to stop using it.
Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the maximum amount the law allows.
Acceptable use
You agree to use the site only for lawful purposes. You may not attempt to disrupt the site, scrape it in a way that harms performance, probe for vulnerabilities, or use automated means to abuse the service. You may not misrepresent your affiliation with us or use the site to distribute malware or harass others.
Intellectual property
Text, layout, and original graphics on this site are owned by us or used with permission. You may link to our pages and share our tools for personal use. You may not copy large portions of the site for commercial republication without permission.
Links
The site may link to third-party websites. We are not responsible for their content or privacy practices.
Governing law
These terms are governed by the laws applicable in the United States, without regard to conflict-of-law rules. If any provision is found invalid, the rest remains in effect.
