You overpack. Most people who do it have never run the math.
Most people who run the math switch quickly.
TL;DR The average overpacker spends $200 to $400 per year on costs they would not pay if they packed properly. The biggest line items are baggage fees, overweight surcharges, and emergency destination buys.
I’ve weighed my carry-on at hundreds of check-in counters, my “overpacking cost” line for the past decade is roughly $0. The math drove the change.
The cost breakdown.
Checked bag fees. $35-50 each way. $70-100 per round trip.
Two trips a year, $140-200.
Overweight surcharges. $50-100 per bag. Even one per year averages $75.
Emergency destination buys. Forgot something, bought it overpriced. $30-50 per trip on average.
Pre-paid baggage you did not need. Booked “just in case.” $30-60 per trip.
Conservative annual total: $200-400. Often higher for frequent travelers.
The 10-year compounding.
$200-400 per year is $2,000-4,000 across a decade. Money to airlines and tourist gift shops, not to your trips.
None of it bought you better travel. It was overhead on bad packing.
The fix.
Carry-on only, weigh at home, pack what you actually need (not “just in case”), bring duplicates of nothing the destination supplies.
Each move kills one of the 4 line items above.
