What Is the Tip Calculator | Split Bill?
A tip calculator removes the mental arithmetic from splitting a restaurant bill. Enter the bill amount, choose a tip percentage, specify the number of diners, and instantly see exactly what each person owes, including the tip share per person.
US Tipping Norms
- ›10%, below average; reserved for poor service
- ›15%, acceptable for average service
- ›18%, good service; increasingly the baseline in major US cities
- ›20%, standard for good service; the easiest to calculate mentally
- ›22–25%, excellent service or fine dining
- ›30%+, exceptional service or when you want to make an impression
Round-Up Feature
- ›Rounding each person's share up to the nearest dollar simplifies cash payments
- ›The calculator shows the implied actual tip percentage after rounding
- ›Useful when splitting without card payments at the table
Formula
Tip Amount
Tip = Bill × (Tip% / 100)
Total Bill
Total = Bill + Tip
Per Person
Per Person = Total / Number of People
Tip Per Person
Tip Each = Tip / Number of People
Round-Up
Suggested Total = ceil(Per Person) × People
Implied Tip %
(Desired Total − Bill) / Bill × 100
How to Use
- 1Enter the pre-tax bill total in the Bill Amount field.
- 2Select a tip percentage using the preset buttons (10%–25%) or type a custom %.
- 3Use the − / + buttons or type the number of people splitting the bill.
- 4Toggle "Round up per person" to see how much each person pays rounded to the dollar.
- 5The result shows: tip amount, total bill, amount per person, and tip per person.
- 6The Tip Guide table shows all standard percentages at a glance for your bill amount.
Example Calculation
Dinner for 4, bill = $87.50, 20% tip:
Tip = $87.50 × 20% = $17.50
Total = $87.50 + $17.50 = $105.00
Per person = $105.00 ÷ 4 = $26.25
Tip each = $17.50 ÷ 4 = $4.38
Round-up: ceil($26.25) = $27.00
Rounded total = $27 × 4 = $108.00
Implied tip% = ($108 − $87.50) / $87.50 = 23.4%
Result
Each person pays $26.25 exactly, or round up to $27.00 for easy cash, that adds a slightly more generous 23.4% tip.

Frequently Asked Questions
What is the standard tip percentage in the US?
- ›15%, historically standard, now considered the floor for acceptable service
- ›18%, the growing US baseline, especially in cities with higher cost of living
- ›20%, easy to calculate (move decimal left, double it) and widely considered standard
- ›22–25%, fine dining, exceptional service, or when you want to be generous
Should I tip on the pre-tax or post-tax amount?
Both are accepted practices, the difference is small:
- ›Pre-tax: technically the "correct" basis for the tip
- ›Post-tax: more common in practice and slightly more generous to the server
- ›On a $100 meal with 8% tax: pre-tax 20% tip = $20 vs post-tax = $21.60, a $1.60 difference
- ›Either approach is fine; consistency matters more than which base you use
How do I calculate a 20% tip mentally?
- ›20%: move decimal one left to find 10%, then double, $85 → $8.50 → $17.00
- ›15%: find 10%, halve it to get 5%, add them, $85 → $8.50 + $4.25 = $12.75
- ›18%: find 20% then subtract 2% (one-tenth of 20%), $85 → $17.00 − $1.70 = $15.30
- ›25%: divide by 4, $80 ÷ 4 = $20.00
Do I need to tip at counter service or fast casual restaurants?
- ›Counter service (order at register, pick up food): tipping is optional, not expected
- ›Fast casual (food brought to table or some table service): 10–12% is a reasonable gesture
- ›Coffee shops: $1–2 per drink is common if you are a regular or the order was complicated
- ›Full sit-down service with a dedicated server: 18–20% is the standard expectation
What is the round-up feature in this calculator?
- ›Rounds each person's share to the nearest whole dollar (always up, never down)
- ›Shows the adjusted group total and the implied tip percentage after rounding
- ›Example: $26.25 per person → $27.00 → group total $108 on an $87.50 bill = 23.4% tip
- ›Saves the awkward exchange of coins and makes the math obvious for everyone at the table
How should I tip if service was bad?
- ›Server's fault (rude, inattentive, wrong orders): 10–15% reflects the poor service
- ›Kitchen fault (long waits, wrong food): server isn't responsible, tip normally at 18–20%
- ›Leaving no tip is appropriate only for genuinely offensive service, not inconvenience
- ›Consider speaking to a manager instead of, or in addition to, adjusting the tip
Should I tip on alcohol or just food?
- ›Standard practice: tip on the entire bill including all food and beverages
- ›Servers earn tip-wage rates that assume full-bill tipping on alcohol
- ›For expensive wine (over $100 a bottle): some tip 15% on wine and 20% on food, acceptable variation
- ›For cocktails at a bar: $1–2 per drink is common; for table service include drinks in the full bill tip
