Help with a tool
Every tool page starts with a quick answer, then shows how to use the tool, the formula it applies, worked examples and frequently asked questions. If a result looks unexpected, compare your inputs with the worked examples on the same page: most differences come from units, percentages entered as decimals, or a date or time zone setting.
Step-by-step guides
The blog explains the most common calculations in detail, such as discounts, percentages, profit margin, gross profit, exact age, Celsius to Fahrenheit, military time and the word count in Google Docs. Each guide links to the tool that does the work.
Privacy and advertising questions
The privacy policy explains what the website does with information: the tools run in your browser and the website does not collect messages, accounts or personal details. Ads are served by Google AdSense; you can manage ad personalisation in Google’s Ads Settings at https://adssettings.google.com/.
How the tools are kept accurate
Formulas are checked against worked examples and official sources such as the IRS, the Social Security Administration and the California Franchise Tax Board. Figures that change every year, like tax brackets, are dated on the page that uses them, so you can always see which year they apply to.
