Frequently Asked Questions

What's the actual lottery EV?
European/state lotteries return 50-65% of ticket sales as prizes (rest = state revenue + admin). EuroJackpot: ~50%. German Lotto 6aus49: ~50%. US Powerball: ~55%. Scratchers: 60-70%. Expected return on every €1 spent: ~€0.50-€0.65. Math: you lose 35-50% on every ticket on average. Long-term, you lose.
But someone wins!
Yes — but the EV (expected value) of YOU winning the jackpot is microscopic. EuroJackpot odds: 1 in 140 million. To have a 50% chance of winning once, you'd need to play ~97 million times. Coût: €194 million. Reward: typical jackpot ~€20-90 million. The math is upside-down even for "lucky" winners.
Isn't it just entertainment?
It can be. €5-10/week as entertainment is fine — same category as Netflix or coffee. The point of this tool is HONEST accounting. If "entertainment" turns into €50/week × 30 years = €78,000 spent + €15,000 in expected loss + €100,000+ opportunity cost if invested, that's not entertainment, that's a tax on hope.
What's the better strategy?
If you genuinely want a chance at financial freedom: invest the same money. €40/week × 30 years × 7% = €234,000. Nont lottery-jackpot money but life-changing in middle age — and guaranteed by basic compounding, not 1-in-140-million luck.
