Let's be frightfully honest.
$779/month is not a retirement income anywhere in the western world.
Just because you can eek by at the moment on $800 a month does not mean that is the income you need in retirement.
Living on $800/month would not be retirement. It would be a financial prison sentence.
I know that Jacob from ERE lives on less than this, but the reality is that this model is certainly not applicable to 99.999% of people.
$800 might sound fine, until you need a root canal treatment, or you need some eyeglasses in old age (Even in the UK these are not covered).
I'm 26.
I lived in Berlin from 20-25 and worked with a bunch of interns that would take home around $500 a month.
You can live off of it, if you are a 20 something kid, sure.
But it is not a wage you can retire on, raise a family on, grow old on.
Even then, you are reliant upon employer healthcare.
Different strokes for different folks, but I lived in a squat in Berlin and would eat at Volksküche on a regular basis.
It's not a lifestyle I can see any smart person holding for 40-50 years in retirement.
All too often, people assume their current lifestyle will be how they always live, with no emergency costs, no inflation, no family or financial dependents.
This is a recipe for financial ruin. No mistaking.
Realistically, as a single man with no dependents, I am projecting a stash of $1.25MM for FI giving SWRs
4% $50k.
3% $37.5k
Allowing for inflation, the $37.5k is around $27k in 2014 dollars. I feel this is the minimum I could retire on and potentially raise a family if I were very conservative and had a paid off house.
Without a paid off primary residence, the stash comes closer to $1.5MM giving SWRs:
4% $60k
3% $45k
The idea of retiring on $779/month, at 4% SWR, for the rest of your life, is at best naive and at worst ruinous.
Measure twice. Cut once.
