Tip Calculator

In the US, standard restaurant tipping etiquette: 15% for adequate service, 18–20% for good service, 22–25% for excellent service. For buffets, 10% is common since staff effort is lower. For takeout, 10–15% is appreciated but not required. Pre-tax vs post-tax: it's customary to tip on the pre-tax subtotal, though many people tip on the total for simplicity.

For 20%: move the decimal left one place to get 10%, then double it. Example: $47 bill → $4.70 (10%) → $9.40 (20%). For 15%: get 10%, then add half. Example: $47 → $4.70 + $2.35 = $7.05. For 18%: get 20% and subtract 10% of that. Example: $47 → $9.40 − $0.94 = $8.46.

Technically, tipping on the pre-tax subtotal is the traditional etiquette — the server's service is for the food, not the government's tax. In practice, most Americans tip on the post-tax total for simplicity, and the difference is small (a few cents to a dollar on most bills). Both approaches are acceptable.

For food delivery (DoorDash, Uber Eats, Grubhub): $3–5 minimum for short distances, 15–20% for larger orders, 20–25% for bad weather or difficult deliveries. For pizza delivery, $3–5 is standard. Note: delivery fees charged by the app generally do not go to the driver — the tip is separate and goes directly to them.

Hotel tipping guide: Bellhop/porter: $1–2 per bag ($5 minimum). Housekeeping: $3–5 per night, left daily (staff rotates). Concierge: $5–10 for significant help, nothing for simple directions. Room service: check if gratuity is already included on the bill (often 18–20% is added automatically). Valet parking: $2–5 when picking up your car.

Bill splitting divides the total (bill + tip) equally among the number of people. This calculator shows the tip per person and total per person separately so you can see both. It also shows the total tip amount and total bill for the group. For unequal splits (someone ordered more), adjust the bill amount to each person's share before calculating.
