Gosh, but you're doing it the hard way.
I'll give you an example.
We have 4 income streams:
1) Social Security
2) Rental House Income.
3) Rental Farm Income.
4) Stock and Bond dividends, interest and appreciation.
Our expenses include:
5) A fixed rate mortgage.
6) Food, clothing, insurance, transportation, etc.
Now let's look at inflation and its effect on those:
1) Social Security -- includes cost of living adjustment (COLA).
2) Rental House Income - adjusts with COLA but lags a year or two behind.
3) Rental Farm Income - adjusts with COLA but lags a year or two behind.
4) Stock and Bond Index Fund dividends, interest and appreciation - I just subtract out average inflation from it's historically average earnings.
Our expenses include:
1) A fixed rate mortgage -- Doesn't change with inflation. :)
2) Food, clothing, insurance, transportation, etc. -- adjusts with inflation.
So, 2 of my 4 income streams keep up with inflation and the other two slightly lag it. One of my bigger expenses does not increase with inflation and goes away in 12 years, freeing up additional income. I pretty much assume they will cancel each other out and I factored in a slightly lower withdrawal rate in case I'm a bit wrong.
In other words, I really don't do anything near as hard as you're doing. :)
