Quick answer. Tip = bill × tip% ÷ 100. Per person = (bill + tax + tip) ÷ people. Example: $60 bill, 18% tip, 2 people: tip $10.80, total $70.80, $35.40 each.
How to use the tip calculator
- Enter the bill before tax (the subtotal on the receipt).
- Pick a tip with the 10–25% buttons or type any percentage.
- Add people to split the bill evenly.
- Add tax as an amount or a percentage, and choose whether the tip is on the pre-tax subtotal (default) or on the total with tax.
- Tick rounded up to see an easy whole-dollar amount each person can pay.

How much to tip
In the US, 15–20% is common for table service, with 18–20% typical in cities and 20–25% for excellent service or large groups. Many restaurants add an automatic gratuity for parties of six or more, so check the bill before adding more. Customs vary by country: in much of Europe and Asia service is included or a small round-up is enough.
Quick mental maths
For 10%, move the decimal point one place left ($64 → $6.40). Double it for 20% ($12.80), or add half of 10% for 15% ($9.60). For other percentage questions use the percentage calculator, for shop deals the sale and discount calculator, and for travel sizes and weights the unit converter.
Frequently asked questions
How do I calculate a tip?
Multiply the bill by the tip percentage and divide by 100. A 20% tip on $45 is 45 × 20 ÷ 100 = $9.
Should I tip on the amount before or after tax?
Etiquette guides usually say before tax, which is this calculator's default. Choose "Total including tax" if you prefer to tip on the full amount; the difference is small.
How do I split a bill with a tip?
Add the tip and tax to the bill, then divide by the number of people. The calculator shows both the tip share and the total share per person.
What is a good tip percentage?
In the US, 15% for basic service, 18–20% for good service, and 20–25% for excellent service or large groups are common guidelines.
What does rounding up per person do?
It rounds each share up to the next whole dollar so everyone can pay an easy amount. The extra goes to the tip, and the calculator shows how much it adds.
Does it work in other currencies?
Yes. The maths is the same for any currency; just ignore the dollar sign.
Is anything I type saved?
No. The calculator runs in your browser and nothing is stored or sent.
