Why these show their working
Every tool here prints its intermediate steps rather than returning a single number. That is deliberate. A comparison tool that hands you an answer asks you to trust the tool; one that shows the arithmetic lets you check it, and disagree with it.
It also means none of these need your data. Nothing is uploaded, nothing is stored, and no account is required — the calculations run in your browser. For a site that audits what other software sends to third parties, tools that phone home would be difficult to defend.
Where a figure has to come from somewhere — a mid-market rate, a provider's quoted fee — you enter it, dated, from a source you chose. Nothing here fetches a rate and asks you to believe it.
