Formula
Tip amount = bill × (tip% ÷ 100)
Total with tip = bill + tip amount
Each person pays = total with tip ÷ number of people
How it works
This calculator computes the gratuity by applying the chosen tip percentage to the pre-tip bill total, adds it to arrive at the grand total, then divides evenly among the number of diners. All three values — tip amount, total, and per-person share — are returned simultaneously.
The split assumes an exactly equal division; it does not account for individual item differences or rounding to the nearest cent. For real-world use, each person's share may need to be rounded up to the nearest currency unit, which can leave a small residual to be handled separately.
Worked example
Worked example: $120 bill, 18% tip, 4 people
- Tip amount = $120 × 18 ÷ 100 = $21.60.
- Total with tip = $120 + $21.60 = $141.60.
- Divide by 4 people: $141.60 ÷ 4 = $35.40.
Tip: $21.60 | Total: $141.60 | Each person pays: $35.40.
Common mistakes to avoid
- Calculating tip on the post-tax total instead of the pre-tax subtotal — tipping on tax slightly overpays; the convention in most countries is to tip on the food and drink subtotal.
- Splitting the bill before adding the tip, then tipping individually — this is correct only if everyone tips the same percentage; otherwise apply tip to the total first.
- Rounding each person's share down — small rounding errors across a large group can leave the total short; at least one person must round up.
Key terms
- Gratuity (tip)
- A voluntary payment above the stated price, customarily given to service staff; typically expressed as a percentage of the pre-tax bill total.
- Pre-tip total
- The bill amount before any gratuity is added; the base for calculating the tip percentage.
- Even split
- Dividing the total cost into equal shares regardless of what each person ordered; the simplest but not always the fairest method.
- Rounding error
- Small discrepancies that arise when a per-person share is not a whole number of cents, requiring one party to pay slightly more or less to cover the exact total.
- Standard tip range
- In the United States, a typical restaurant tip is 15–20% of the pre-tax bill; 18% is a common default for adequate service.
Frequently asked questions
- How do I split a bill with tip?
- Add the tip (bill × tip%) to the bill total, then divide by the number of people. For example, a $120 bill with 18% tip = $141.60 total ÷ 4 people = $35.40 each.
- What tip percentage should I leave?
- 15% is the minimum for decent service, 18–20% is standard, and 20–25% for excellent service. Some cities have higher norms.
