Terms of Use
Last updated: October 3, 2026
Welcome to HowCalculate.com. By using this site, you agree to these terms. If you don’t agree with them, please don’t use the site.
Who runs this site?
HowCalculate.com is run by Ajay Kumar. You can reach me at howcalculate@gmail.com.
What does the site offer?
HowCalculate provides free online calculators and written guides for advertisers, marketers, and online sellers. Everything on the site is there for general information.
Results are estimates, not advice
The calculators work out results from the numbers you enter, and they can only be as accurate as those numbers. Nothing on this site is financial, legal, tax, or professional advice. Fees, rates, and benchmarks change, so check important figures on the official website of the platform or company involved before you rely on them. See the Disclaimer for more details.
How can you use the site?
You’re welcome to use the calculators for personal or business purposes. Please don’t:
- Use the site in a way that is unlawful or harms other people.
- Try to break, overload, or gain unauthorized access to the site or its systems.
- Use automated tools to copy large amounts of content from the site.
- Pretend that the site’s content or tools are yours.
Ownership and sharing
The text, calculators, design and code on this site belong to me, unless it says otherwise. You may link to any page and quote short excerpts with credit and a link back. Please don’t copy whole pages, tools, or articles, or republish them elsewhere, without my written permission.
Third-party links and trademarks
Some pages mention or link to other companies and websites, such as payment platforms and ad networks. I don’t control those sites and I’m not responsible for them. HowCalculate isn’t affiliated with, endorsed by or sponsored by any company mentioned on the site. All trademarks belong to their owners.
Advertising
The site may show ads, including ads served by Google and other partners. Ads don’t influence the results or content, and I’m not responsible for the products or services advertised. See the Privacy Policy for how advertising cookies work.
No guarantees
I work hard to keep the site accurate and available, but it’s provided “as is” and “as available.” I don’t promise that it will always be error-free, up-to-date, or uninterrupted. I may change, fix, or remove any content or tool at any time.
Limits on my responsibility
To the fullest extent the law allows, I’m not liable for any loss or damage that results from using the site or relying on its calculators or content. That includes lost profit, lost revenue, or business decisions made using the results. Nothing in these terms limits any rights you have that the law doesn’t allow to be limited.
Changes to these terms
I may update these terms from time to time. When I do, I’ll change the date at the top. If you keep using the site after that, it means you accept the new terms.
Governing law
These terms are governed by the laws of India. Any dispute connected with the site will be handled in the courts of India, unless the law where you live says otherwise.
