Why this isn't a free calculator
Most free inheritance tax calculators ask for a few high-level numbers and give a rough estimate. They typically don’t model more complex, multi-step estates or let you revisit and update the calculation over time.
YOEFI saves your estate record and applies HMRC allowances and rules consistently — so gifts, transfers, and allowances are all stored long term, you can come back and recalculate whenever things change or you remember old assets.
You're not paying for a number.
You're paying for a complete estate snapshot.
