If you get a return of 9%, and inflation is 5%, what is your real return?
You might think it's (return - inflation)
=> 9% - 5% = 4%
Well, that's actually just an estimate. Here is how you calculate the real, real return (for real!)

Let's say you had R100.
And let's say that, coincidentally, a widget also costs exactly R100
Using some advanced Maths, you can work out that your money can buy you precisely 1 widget.

Using some advanced Maths, you can work out that your money can buy you precisely 1 widget.
Now, let's say instead of buying a widget with your R100, you invested it and got a 9% return.
After 1 year, you will have R109
In that same year, inflation (at 5%) will mean the price of the widget is now R105
After 1 year, you will have R109
In that same year, inflation (at 5%) will mean the price of the widget is now R105
So that means you can now buy R109/R105 = 1.038 widgets
I.e. In widget terms (what your money can actually buy) you are 3.8% better off than a year ago
So your real return is 3.8%
(Not quite the estimate of 9% - 5% = 4%)

So what's the big deal, why does the difference matter?
Well, in low inflation, lower return environments like the US and Europe, it doesn't matter that much.
E.g. with returns of 5% and inflation at 1%
Estimated real return => 4%
Actual real return => 3.96%
No biggie
