Inflation Pass Through

I recently found out that there are two formulas for inflation pass through.
When do you use (1/(r+((1-pass through)*infl)) and when do you use the other formula?
 
What’s the other formula? I only recognize the one you gave for calculating inflation flow through.
 
the one on the mock had it r-inflation + (1-pass thru)*inflation
and it had me stumped because the formula u used didn’t get me the right answer. I think it was the last question on the PM

the original formula is for real rate, this one just subtracts inflation from nominal rate to get the real rate.
 
Sorry for the confusion. I guess there is only one formula.
So if I am given r in real terms i just do 1/(r+(1-pass through)*infl))
If given in nominal terms 1/((r-i)+(1-pass through)*infl))
Is that right?

i guess..
 
Yes, that’s correct.
I found the mock question which Zero mentioned, it’s question 60 on the 2011 AM mock. In this question they provide the nominal rate of return, so we needed to subtract inflation to get the real rate (as you’ve shown above).
Cheers
 
Check out ?’s 13 & 14 of reading 38, it’s the same formula, but they specify real vs nominal rates for each question. Formula calls for real rate of return to be used, so if they give nominal we have to adjust for inflation. And per mock it looks we should assume nominal unless stated otherwise.
 
Chuckrox8,
Did you finish ethics review? Any points to pay special attention.
 
P/E1 = 1/(r- FlowThrough%*Inflation).
Why the complex formula?
r here is nominal…you can always go back and forth between real and nominal, nominal rate = real rate + inflation.

Ethics is always such a curveball. It goes without saying that soft dollars will be on the exam. I would recommend reading the actual CFAI guide to soft dollars that’s on their website. It’s much more straight forward than the text. I think we’ll see probably six questions relating to the standard and code and then probably 3 or 4 on soft dollars and a couple on prudent investor. Ethics is tough. I can guarantee you that you will be scratching your head on a few of the questions.
Although it’s getting late, I would definitely look at some of the differences between old vs. new prudent investor, flip through Ethics EOC, and look at some of the case studies. Ethics can be easy points, but it can also be a deal breaker.

The other formula maybe more intuitive since you add to real required return whatever left of inflation due to flow-through.
