Our Methodology & Sources
Last updated · Reviewed by SnapTipCalc Editorial
SnapTipCalc's tipping guidance is not opinion. Every percentage, dollar range, and country recommendation on this site is grounded in primary sources — government wage data, peer-reviewed consumer research, and direct policy from industry bodies.
How we set percentage ranges
When we say "tip 15–20% in US sit-down restaurants," that range reflects three overlapping data points:
- Federal wage structure. The federal tipped minimum cash wage is $2.13/hour (US DOL). Tips are the primary income for most tipped workers.
- Consumer survey data. Pew Research (2023) and Bankrate (2024) show a median tip of 18–20% for sit-down service among Americans who tip.
- Regional & industry norms. Fine dining and major urban markets skew 20–25%. Counter service and takeout are optional.
How we set country-by-country guidance
International tipping norms come from a mix of embassy travel advisories, local labor law (whether a service charge is legally required), and large-sample traveler surveys.
Update cadence
- Wage & survey data: re-checked every 6 months against the latest BLS and Pew/Bankrate releases.
- Country guidance: reviewed annually, and immediately when a country changes its service charge law.
- Calculator defaults: reviewed whenever the underlying percentage ranges shift by more than 1 point.
