Using the collection
What information does the website retrieve?
The bundled calculators use your entered values. They do not fetch live records, rates or provider decisions.
Are starting values recommendations?
No. They are replaceable examples for demonstrating a method. Use information that fits your own situation.
Do I need an account?
No visitor account is created or needed for the calculators. WordPress administrative accounts are separate.
Can I save a result?
After calculating, use Download result or Print result. Exports include current entries; review them before sharing.
Why did the download button become disabled?
Changing an input makes the old result stale. Calculate again to refresh it before exporting.
Does Reset sample erase my downloads?
No. It resets the open tool’s sample fields and result. It cannot remove files already saved elsewhere.
Is the appearance preference stored?
The display choice can be saved in site-specific localStorage. It does not save calculator entries.
Can a positive margin be treated as approval?
No. A margin only describes the entered formula and assumptions. It is not a safety, suitability or professional judgement.
How do I report a calculation issue?
Send a harmless reproducible example and the tool name through Contact. Avoid private records, passwords and other sensitive information.
Does the site provide medical, financial or legal advice?
No. Tool-specific boundaries explain what is not assessed. Seek qualified help where your decision requires it.
Are emails guaranteed to arrive?
No. WordPress/CF7 acceptance and inbox delivery are different. Use an alternate email route if needed; a response time is not guaranteed.
