💡 5 Fun Facts about Tipping

Menus can nudge you

Suggested tip buttons (18% / 20% / 25%) anchor your choice. Research shows people tip higher when the “middle” option is already generous.

Choice architecture

Tax or no tax?

In many places, servers expect tips on the pre-tax subtotal, but POS devices often default to after-tax. This tool lets you flip either way to see the difference.

Rounding calms the table

Rounding to the nearest whole unit or 0.05 not only keeps splits tidy—it also reduces “penny friction” when everyone is paying with phones.

Smooth checkout

Tip pools change incentives

Some restaurants pool tips across servers, bar, and kitchen. That can reduce variability in take-home pay and subtly affect how staff pace service.

Behind the scenes

Global quirks

In Japan and parts of Europe, tipping can be rare or even refused. In the U.S. and Canada it’s standard. Always check local norms before adding extra.

Travel tip

How the tip is calculated

  • Tip = Base × (Tip% / 100), where Base is either the full bill or the pre-tax subtotal (your choice).
  • Total = Bill + Tax + Tip.
  • Per Person = Total / People.
