Sure, I mean, and to be fair, you know, I still do research where I assume penny rises by inflation.
So it's a very common assumption.
Like I still use this out there a lot, but I think that like one of the most important questions we've got to ask ourselves looking about retirement is like, how do we think,
spending is gonna change over time, right?
And the most common assumption that we use in research and financial planning tools and all this is that spending is gonna increase every year by inflation.
So effectively, what you're gonna spend in the future is the same as what you spend today in today's dollars, right?
historically, inflation is averaged about 3% a year.
So we would assume that every year you'll spend effectively 3% more.
In a piece of research I wrote that was published about a decade ago, and then an updated piece that was just released in the Financial Planner Review, I kind of revisit this topic of, well, how does spending change over time?
And there's pretty convincing evidence that most people as they move through retirement won't increase their spending by the full amount of inflation.
So for example, if inflation is 3% a year, you might only spend 1% a year per more.
And that kind of comes
compounds over time.
that's one of the most common questions I get asked about this research, both currently and then historically.
And I think it's a mix of both, right?
But one thing that we can do is look at retirees who have lots and lots of money and see how their spending changes.
And so even if you just focus on retirees who could spend more, so they're very well-funded, they actually tend to cut back as well.
So I think that a lot of this actually just is
choices.
It's kind of a fun model.
