If a tool helped you, the simplest thanks is a link from a page where your readers would find it useful, for example a school worksheet, a finance blog post or a help article. Every tool page has a short, permanent address such as /tools/emi-calculator that will not change. Copy the snippet below or use the tool address directly.
We only ask for natural, editorial links. We do not buy, sell or exchange links and we do not use automated link tools.
When you reference a result in a report or article, mention the tool name, the inputs you used and the date, and link to the tool page. Results from calculators are estimates for learning and planning, so always confirm important figures with the relevant institution.
