Calculators

Each of these is a form around a guide’s fact ledger. The rates are not typed into the calculator: they are read from the guide that sources them, where every figure carries a link to the provision it comes from and the date somebody last checked it. When a rate changes in January, the guide and the calculator move together.

Every figure above is computed by the calculator it sits on, at the rates in force today. A calculator answers one question quickly and cannot tell you which question to ask, so each links to the guide behind it, which is where the exceptions live: who the rule does not apply to, what changes above a threshold, and what the figure is not.
