Last updated: 22 October 2026. By using powercalculators.com or the Financial Calculator app, you agree to these terms.
Power Calculators provides free online calculators and related content. You may use the website and app for personal, non-commercial purposes. You agree not to misuse the service — for example, by attempting to disrupt it, scrape it at an abusive rate, or submit spam through the ratings or contact form.
Creating an account is optional and requires accurate information (a valid email address) and a password you keep confidential. You are responsible for activity under your account. You must be at least 13 years old to create an account. Signed-in features include saved calculation history (which you can switch off or delete at any time) and bookmarks. You may delete your account at any time from the My Profile page or the app's account screen — see our Privacy Policy for exactly what that removes. We may suspend or remove accounts that break these terms.
All calculator results are estimates provided "as is" — see our Disclaimer for details. We do not guarantee the service will be uninterrupted, error-free, or that any particular calculator's rates or rules are fully up to date at any given moment.
The website is free to use and is supported by advertising from Google AdSense. You agree not to interfere with, hide, or artificially click on ads. Ads are provided by third parties, and we are not responsible for their content or for sites you reach through them — see the Disclaimer.
If you submit a rating, review, or contact message, you agree not to include unlawful, abusive, or spam content, and not to impersonate anyone. We may remove or moderate submitted content at our discretion, including holding new ratings for review to prevent abuse.
The design, code, and original content of Power Calculators belong to its operator. You may not copy, republish, or redistribute substantial parts of the site or app without permission.
The explanatory images on this site (formula and conversion cards, "how to measure" illustrations and calculator pictures) are © Power Calculators. You may share them for free — in articles, lessons, presentations or social media — as long as you credit “Power Calculators” and link to the page the image comes from. You may not sell them, use them in advertising, or edit them to remove the credit. For any other use, contact us for permission.
We may add, change, or remove calculators and features at any time. We may update these terms; continued use after a change means you accept the updated terms.
To the fullest extent permitted by law, Power Calculators and its operator are not liable for any indirect, incidental, or consequential loss arising from your use of the service. See our Disclaimer for more on relying on calculator results.
These terms are governed by the laws of India.
