I track my expenditure accurately. Over the last 13 years, the rise in my cost of living has been zero. This is for true, like for like tracked expenditure. CPI has risen around 38% in that time. My view is that CPI is hopelessly flawed in its methodology. Any other views? Is there anyone else that tracks and find their expenditure matches CPI?
This seriously affects my personal finance (which is why it very much is ON topic...) For example, in order to budget I need to put in a value for inflation. I have, in the past, used the central bank target for this- only to find it does not apply to me (in the same way that CPI does not.) I am searching for why this error occurs, hence this question.
