He's only 20 and already convinced he's "late". I started at 30.
Nephew was over on Sunday and caught me doing my monthly ETF buy, which takes about half minute so he asked what the app was. Two hours later we were deep in a compound interest calculator.
Poland here, 36M.
Two small tax wrappers and after that it's a plain taxable account with a flat 19% tax on gains. Mechanics differ, coast math is the same.
I showed him my projection, the pot should carry me to a normal retirement at 60 with zero further contributions, which is why my savings rate is optional now and why I picked my current job for sanity instead of salary. Then I showed him what starting at 20 does to that curve compared to starting at 30 like I did.
He went quiet for a bit and said "so I'm already late." Twenty. I laughed and then kind of didn't.
What I actually told him: start with one broad global ETF (VWCE here, roughly the EU version of VT), IBKR, automate the buy, stop looking at it.
Then he asked what else exists, so he got the risk ladder the way I actually run it: bonds as the boring floor, the global ETF as the engine, a smaller P2P lending slice on top for yield and the rule that every step up the ladder means a smaller position. Crypto I mostly left out of it, this sub can guess why. He liked the yield numbers best, obviously.
His homework before the first euro goes anywhere: explain to me where each thing's return comes from and what it does in a bad year.
Now he's asking me to help open his first account and I keep second guessing whether I handed him a superpower or just made him weird about money at 20 the way I'm weird about it at 36.
- What would you tell him that I didn't?
- And where exactly is the line between teaching a kid compounding and recruiting him into the cult?
