A small workshop of reckoners, each built on sourced figures. Use them to estimate, not to decide — every result should be confirmed before you act.

The tools

Inheritance tax calculator — bands, reliefs and the 2027 pension change. Who inherits? — the intestacy rules where there is no will. Probate fee calculator — the £526 court fee and copies.
