How the numbers are made.
Several ways in, depending on how deep you want to go. They run from a plain-language tour of what the simulator models, through the full mathematics and a country-by-country account of how tax is worked out, to a guide for reading your own results and an honest list of what the model does not capture.
- How it works
How it works
A plain-language tour of what the simulator models, with no math required. What each risk is, why it can sink a retirement, and how RetireSafe accounts for it.
Read - Glossary
Glossary
Every term the app uses, in plain language. What it means, where you meet it, and what it changes about your plan.
Read - Technical reference
Technical reference
Every stochastic component the model uses, written down: the distributions, the formulas, and the parameters behind them.
Read - Your country
What we assume about your country
Every number the model assumes for your country on one page: pension, care, healthcare, budgets and tax, each with the source it came from.
Read - Tax by country
Tax by country
What the model charges you in tax, why it recalculates it every year instead of assuming a rate, and a page for each of the twenty countries showing every figure it uses and where that figure came from.
Read - Reading your results
Reading your results
Every number and chart on your results page, defined precisely: your chance of the money lasting, what is left at the end, years funded, and the premium analyses.
Read - Assumptions & limits
Assumptions & limits
What the model deliberately simplifies and what it leaves out, so you can weigh its output with the right amount of salt.
