What is the tip calculator?
In short
An 18% tip on an $85 bill is $15.30, for a $100.30 total; at 20% it's $17.00. Split three ways, that's $33.43 or $34.00 per person. On a $200 dinner for four, a 20% tip is $40 ($10 each) versus $50 at 25% — only $2.50 more per person.
This tip calculator instantly computes the tip amount, total bill, and per-person share for any party size. Choose from preset tip percentages (15%, 18%, 20%, 25%) or enter a custom rate — and use the +/- stepper to split among 1–20 people. Works for restaurants, food delivery, rideshares, haircuts, hotel housekeeping, and any other tipped service.

Worked example
The scenario
Dinner bill of $120, 20% tip, split among 4 people.
The result
Tip: $24. Total: $144. Each person pays $36. If one person doesn't drink alcohol ($30 less food), you can adjust their share manually — the calculator gives you the even-split baseline.
Common use cases
- Splitting a restaurant bill fairly among a group
- Calculating a tip for delivery, haircut, taxi, or hotel services
- Verifying a suggested tip amount on a receipt
- Teaching tipping etiquette to someone new to the US
- Quickly checking if a restaurant auto-gratuity was correctly applied (usually 18–20% for parties of 6+)
