Advertising disclosure

Right now

We have applied to show display ads through Google AdSense. Its code loads on every page, but no ads appear until Google approves the site. The site has no affiliate links, and no company has paid for any page.

Display ads (Google AdSense)

Once approved, ads will be placed automatically by Google, labeled “Advertisement” and kept in reserved spaces so they don’t shift the page. They will never sit between a calculator’s inputs and its result. How Google uses advertising cookies, and how to opt out of personalized ads, is in our privacy policy; we will ask for your consent before personalized advertising where the law requires it.

If we add affiliate links

Any affiliate link will be marked on the page. We would earn a commission if you buy, at no extra cost to you, and it would never change what we recommend, the order of options or the numbers a calculator gives.

Independence

No advertiser or manufacturer reviews, pays for or approves our guides. When we cite a manufacturer’s manual or spec sheet, it is because it is the primary source for that figure. See our editorial policy.
