Sorry, that's the EU account gate rather than a geoblock. You can browse and run the Quick Check from anywhere except Quebec, but account creation is blocked in the EU/EEA/UK/CH, so the full builder is out of reach.

The reason is that GDPR has extraterritorial reach and real penalties, and doing it properly is weeks of work I haven't done for a market I'm not launching in yet. I'd rather block the signup than pretend I'm compliant. Not a satisfying answer if you're the one blocked, I know.

The 0.5% step is because the Quick Check is a 66 cell precomputed grid shipped to your browser, so it runs with no account and no server. The builder takes dollar amounts. On residence, there's an "other, rest of world" mode that runs an untaxed gross projection, so it isn't US only.

The 100% stocks result holds up. In the international panel, bonds get wrecked by inflation more often than equities do, so more stocks wins on "did the money last" while being much rougher along the way. Cederburg and co-authors find the same. That's why the full detailed results show the full distribution and the drawdowns, not one number.
