Free ads calculators and tools
Every tool on this page runs in your browser. There is no account, no email box, and nothing leaves the tab you opened it in: the numbers you type are React state on your own machine and they are gone when you close it. Each calculator shows its working, states which figure it could not compute rather than printing a zero in its place, and links to the definition of the metric it produces so the arithmetic and the meaning sit beside each other. The list below is built from the tools that exist, so it is never out of date.
Every tool
