Where we stand.
These tools are free and you use them yourself. They do the arithmetic, or lay the paperwork out properly, from what you type in. They do not check that what you typed is right, and they are not advice. Roseworth has not reviewed your figures and is not responsible for decisions you take on them. Nothing you enter is sent to us — it stays in your browser. If the answer matters, ask us and we will look at your actual position.
