Analytics

We use Google Analytics to understand which pages and calculators are useful. Depending on your consent choice and location, this may process page URLs, referrers, general device and browser information, approximate location, and interactions such as calculator or outbound product-link clicks. We do not send the numbers you type into calculator fields to Google Analytics.

Advertising, affiliate links & cookies

This site may display advertising served by Google AdSense. Google and its advertising partners may use cookies or similar technologies to measure ads and, where you consent, personalize them. Some product links are Amazon affiliate links; if you make a qualifying purchase after using one, we may earn a commission at no additional cost to you.

For visitors in the European Economic Area, the United Kingdom, and Switzerland, our site defaults consent-dependent advertising and analytics storage to off. When the site consent message is available, it lets you consent, decline, or manage individual options. You can also manage ad personalization in Google My Ad Center.
