The $15 Problem: When "Let's Just Split It" Costs You

Picture this: It's Friday night dinner with five friends. The bill arrives.

"Let's just split it evenly? $45 each?"

The Math Nobody Wants to Do

This happens 71% of the time at group dinners. The research is clear:

  • 45% of people report "someone always overpays or underpays"
  • 58% of diners want item-level control

The Real Cost Over Time

$816 a year subsidizing your friends' appetites. That's a plane ticket.

The Bottom Line

Equal splitting isn't equal when consumption isn't equal.

Stop overpaying. Start splitting fairly.
