The tools you need,
fast, in one place

This page lays out every Calqu tool by section — calculators for tax, payroll, property and finance, text, developer and image tools, and quick mini-games and tests. Skim the blocks below if you want to settle on a category first; if the name of what you need already comes to mind, the magnifier in the header is quicker. Anything you open once stays in the "Recently used" row above for your next visit.

Nothing here needs an install or an account, and most of what you type stays in the browser instead of travelling to a server. A result can be handed on as an address that carries the values, or pasted into a blog post as an embed, so someone else sees the very screen you saw.

Anything tied to money or regulation states which point in time it follows and where the figures come from. Rates, contribution percentages and deduction caps are revised annually, so the same inputs give a different amount under a different reference year. When the subject itself is unfamiliar, reading the matching guide or insight article first makes the outcome much easier to interpret.
