All academic as they say however, for arguments sake, let's say that lump sum for this Wednesday, after taxes, is a check for 600 million.
If your investments are pulling 3-4% a year you aren't investing. Those returns are way too conservative. But hey, again, let's just roll with 5% returns annually.
5% on 600 million.
Now, again, capital gains and other taxes abound (for reasons mostly good - a whole other discussion there....) but let's say that those expenses pull off half of your investment returns annually. That leaves an effective return yearly of 2.5% but hey, screw it, lets round down to 2%.
That's 2 bucks for every 100 returned yearly after taxes. $1000? That's $20 of course.
$200 on $10,000
$2000 on $100,000.
$20,000 a year - in-pocket - on every million stashed.
Times 600...
A paltry 12 million a year and your principle remains intact.
That's a million dollars a month of walking around money. $30,000 a day.
Don't like my estimates? Cut it in half. Make it $500,000 a month and a mere $15,000 a day. And you still have 600 million in the bank.
I think, dear Turnbull, you could live a little more above your means than you stated.
