How these tools work
Each tool on this page is a normal web page with the calculation built in. When you type a number or choose an option, your browser does the work on your device. Nothing is sent to a server, and no file is uploaded.
That approach keeps the tools fast and private, but it also sets a limit: a browser tool can only use the information you give it. It cannot check a live tax rate, look up an address, or read a document from your computer unless the page explicitly says so.
If a tool cannot do something, its page says so in plain language instead of guessing. We add a tool here only when its main job works from start to finish.
Privacy note: the tools do not store what you enter. Closing or refreshing the page clears the inputs.
