Before you write
- Please don't send your financial details. We don't need them to answer questions, and the calculator never sends them to us.
- We can't give personal financial advice. We're happy to explain how the calculations work — see also the methodology.
- Found a calculation that looks wrong? Tell us which inputs you used (example numbers are fine) and what you expected to see.
