TL;DR — Key Takeaways
- →The 90/180 rule is a rolling lookback window — not a calendar reset. One day can make the difference.
- →The tracker shows days used, days remaining, and your earliest possible re-entry date.
- →The date simulator answers: 'if I enter on this date, how long can I stay?'
- →EU/EEA passport holders are automatically exempted from the 90-day count.
- →Schengen overstay consequences: entry bans of 1–5 years for nomads who got the math wrong.
The Schengen 90/180-day rule has cost nomads more than visa fees. Get it wrong and you're looking at entry bans of 1 to 5 years. For someone whose lifestyle depends on EU access, that's not an inconvenience — it's a catastrophe.
The most common mistake isn't ignorance of the rule. It's misunderstanding how it works.
keepmore.money's Schengen Tracker does the rolling window math exactly — days used, days remaining, and earliest re-entry date, updated in real time from your trip log.
Try it free →The Rolling Window Problem
Most people treat the 90-day limit like a quarterly reset. It isn't. It's a rolling 180-day lookback window, recalculated every single day.
Here's the trap: you spend 60 days in Spain in January and 30 in Italy in February. Full 90 days used. You fly to Morocco for a few weeks and assume you reset in April. You don't. On March 1, the window looks back 180 days and still sees all 90. You can't re-enter Schengen until enough of those days drop out of the window — which happens at 181 days from when each one was spent.
The math sounds manageable until you're actually doing it, in your head, for a year's worth of trips.
What the Schengen Tracker Calculates
The tracker does the rolling window math exactly, based on your logged trips. Not an approximation — the actual day count for every possible 180-day window, updated in real time.
Three numbers appear immediately: days used in the current rolling window, days remaining before you hit 90, and the earliest date you can re-enter after exhausting your allowance. The re-entry date is particularly useful — it's the answer to "when can I go back?" calculated precisely, not guessed.
You can toggle between historical (actual logged trips) and projected (extended with simulated future trips) to see how planned travel plays out before you book.
The Date Simulator
The simulator answers a different question: "If I enter on this date, how long can I stay?"
Enter a hypothetical arrival date and it tells you the maximum continuous Schengen stay available from that point, given your current history. Useful when you're comparing two flight options and want to know which one gives you more runway.
EU Passport Holders
EU citizens aren't subject to the 90/180 rule. If you've entered your citizenship in keepmore.money preferences, the tracker knows — it won't flag your Schengen entries as contributing to the 90-day count.
Dual citizens (US + Irish, for example) get this automatically. The EU passport exempts you from the count regardless of which passport you travel on.
One Log, Not Two
Every Schengen-country trip you add to the Residency Tracker feeds the Schengen calculator automatically. You don't re-enter anything. One log, one source of truth.
Check the tracker before you book your next European flight. The math is easy to get wrong mentally. Getting it wrong is expensive.
