UK data and coverage
AER and interest assumptions are editable; they are not product quotes. ISA limits use the stated tax year, while the APR conversion tool only models interest compounding.
Each calculator explains the formula, includes a worked example and identifies the assumptions that can affect your result. Official rule tables and dated price references are linked on the relevant pages.
