Fill in a few things

Still needed: inflation you assume.

We leave rate assumptions blank on purpose. A pre-filled number would read as our prediction, and nobody can predict a return. Put in whatever you think is realistic — then change it and watch how far the answer moves.

Questions people actually ask

What inflation rate should I use?
Whichever you think is realistic — it is your assumption, not our forecast. Note that headline CPI often understates what a particular household experiences: education and healthcare costs have historically risen faster than the overall index.

Understand what the number means

A figure on its own decides nothing. These explain what is being calculated and what changes it.
