TIP
About this calculator
This tip calculator splits a restaurant bill including the tip across any number of people. Enter the pre-tip bill amount, the tip percentage (15% standard, 18% good service, 20% excellent), and the party size. The calculator returns the total bill, the tip amount, and what each person owes if you're splitting evenly.
How to use this calculator
Enter the pre-tip bill amount in dollars. Set the tip percentage — US restaurant convention is 15% standard service, 18% good service, 20%+ excellent service. Enter the number of people splitting the bill.
The calculator returns the tip amount, total bill, and per-person total assuming an even split. For uneven splits (where some people ordered more), calculate each person's subtotal separately, then apply the same tip percentage to each subtotal — fair to the server because their tip scales with the total bill regardless of split method.
Worked example
For a $50 dinner bill, 18% tip, split between 2 people:
Tip: $50 × 0.18 = $9. Total bill: $59. Per person: $29.50.
For a larger group dinner — $200 bill, 20% tip (excellent service), 8 people:
Tip: $40. Total: $240. Per person: $30.
For takeout (typically tip 10% if you tip at all): $35 takeout order, 10% tip, just you: $3.50 tip. Total: $38.50.
For delivery via DoorDash/UberEats: tip the driver 15-20% of the food subtotal (not the inflated app price), with a $5 minimum on small orders. Tipping in the app vs cash matters — cash to driver bypasses the platform's commission.
For large parties (8+): many restaurants auto-include 18% gratuity. Check the bill before adding more — double-tipping is the most common over-payment in restaurant dining.
Common mistakes & waste factors
Tipping on the post-tax total. Standard US convention is to tip on the pre-tax subtotal. Tipping on the after-tax amount adds 5-10% to your tip depending on local sales tax.
Double-tipping when gratuity is auto-included. Parties of 6 or 8+ typically have 18% gratuity already added — read the bill before signing or you'll tip 36%.
UnderTipping on small bills. A $10 lunch order at 15% is $1.50 — too low for the service involved. Many people tip a flat $2-$3 minimum on small tabs.
Forgetting takeout and delivery tips. Cultural norm has shifted — 10-15% on takeout, 15-20% on delivery is now expected. Tip in cash to bypass platform commissions when possible.
Rules of thumb
US tip conventions: 15% standard, 18% good service, 20%+ excellent.
Large parties (6 or 8+): many restaurants auto-include 18% gratuity. Check the bill.
Takeout: 10% standard, 15% for complex orders or great packaging.
Delivery (DoorDash/UberEats/Grubhub): 15-20% of food subtotal, $5 minimum on small orders.
Tip on pre-tax subtotal, not after-tax total.
Quick mental math: 20% tip = double the first digit and slide. A $48 bill: double 4 = 8, slide to $9.60 tip.
International dining differs: most of Europe includes service in the bill (tipping is optional rounding); Japan, China, Korea typically no tip; Latin America 10% standard.
