Have a calculator you can’t find anywhere else? This is exactly the kind of thing that becomes the next one built.
Every calculator on this site started as someone’s real question — usually a search that turned up nothing trustworthy. If that’s you right now, this is the fastest way to get it built.
Tell me what you’re trying to calculate, and any specifics that matter — the more concrete the better. “A calculator for X, factoring in Y” is more useful to me than a general topic area.
