By double retire do you just basically mean your WR is halved from 4% to 2%?
Let us say that I need $20,000 in retirement. I am already retired, and my income from my assets is $50,000, then according to the calculator, I can retire again (double retire), in 12.4 years. If that means I will have an SWR of 2%, I guess it will. However, I think not.
But, the other thing is that in my retirement there are three figures -
- E1 a minimum mandated amount that I have to take each year,
- E2 what my investments actually earn each year, and
- S what I actually spend in a year.
If I use E1 in the tool as my income, and S as my spend - I can retire again in less than 20 years. If I use E2 in the tool as my income, and S as my spend - I can retire again in far less than 10 years.
I think that if you can double retire in less than 16.6 years, you already have a SWR of 2% because 16.6 years is when you are spending exactly 50% of your retirement salary. If you can double retire in 6.8 years, you are spending 25% of your retirement salary, which would equate to a 1% SWR - and E2 makes me less than that.
