About

We build free calculators for take-home pay, housing and everyday money decisions in the United States and Canada. Each tool covers every US state and DC and every Canadian province and territory, or says clearly which ones it covers.

Accuracy comes first. Every rate, bracket and limit is stored with the government page it came from and the date we checked it, and the calculators are tested against hand-worked and official reference cases before a page goes live. See the methodology.

The site is paid for by advertising and, where disclosed, affiliate links. Neither changes a calculation or a ranking. See the editorial and advertiser disclosure.
