Four calculators, and nothing asked in return.
Every one runs in your browser. There is no account, no email box, and no server receiving what you type — which you can verify by opening these in aeroplane mode after the page has loaded.
Where a tool uses somebody else's published rate, the rate is shown, dated, and editable. Nothing here applies a growth multiplier or an industry average, because those are made up and you would have no way to check them.
