Fun Facts

• Splitting bills evenly is a well-studied problem in behavioral economics — research shows uneven eaters subsidized by even splits leads to the 'free-rider' problem at group dinners.
• Venmo, launched in 2009, was originally created by Andrew Kortina and Iqram Magdon-Ismail specifically to solve the pain of splitting restaurant bills between friends.
• The Dutch phrase 'going Dutch' (each paying their own share) dates to the 17th century and was originally a British insult implying Dutch people were too cheap to treat others.

FAQ

Does it handle uneven splits?

Yes — toggle 'unequal split' and enter per-person amounts. Plus a 'rounding kitty' that distributes residual cents so everyone pays a clean number.

Tax and tip?

Both configurable. Tip can be pre-tax or post-tax (some regions default differently). The tool shows the computed amount for each mode.

What if someone didn't have alcohol?

Advanced mode lets you assign items to specific people. Alcohol, shared appetizers, and individual orders can all have different split rules.

Can I share the breakdown?

Copy as plain text (works in Slack, SMS, email) or share a URL with the state encoded. URL mode is shareable but reveals prices — use plain text for privacy.
