Questions people ask
What is the 4% rule?
A rule of thumb from US research: taking about 4% of your pot in the first year, then raising it with inflation, has usually lasted 30 years. Some planners now use 3% to 3.5% for longer retirements.
Why is everything in today’s money?
So you can compare it with what you spend now. We take inflation off the growth rate, so a result of $1 million buys what $1 million buys today.
What should I enter as my pension?
Your expected state pension (Social Security in the US, the State Pension in the UK, CPP and OAS in Canada) plus any work pension, per year, in today’s money.
