It answers in a sentence
Every result comes with a plain-English reading of it and a band showing the same plan at three different return assumptions, generated from the same figures. Your readers get the honest range, not one confident-looking number.
It does not watch your readers
No cookies are set by the frame, nothing anyone types is transmitted anywhere, and there is no analytics or fingerprinting inside it. The arithmetic runs in the reader’s browser. You are not adding a tracker to your page.
The credit line is genuinely optional
Untick it and the code drops it. Nothing stops working and nothing is withheld. Google’s guidelines treat a link you are required to publish as a link scheme, so requiring one would be bad for you and bad for us. Keep it if the calculator earned it.
