Tip Calculator
Enter your bill amount, the tip percentage you want to leave, and the number of people splitting the check. The calculator returns the tip amount, the total bill, and exactly what each person owes.
How to calculate tip
Multiply the bill by the tip percentage divided by 100 to get the tip amount, then add it to the bill for the total. Dividing the total by the number of people splitting the check gives an even amount per person, and dividing just the tip by the same headcount shows how much of that per-person share is the tip.
Tip = bill x (tip% / 100); total = bill + tip; per person = total / number of people
Worked example
A $85.00 bill, a 20% tip, split evenly across 4 people.
- Tip amount: $85.00 x (20 / 100) = $17.00
- Total bill: $85.00 + $17.00 = $102.00
- Total per person: $102.00 / 4 = $25.50
- Tip per person: $17.00 / 4 = $4.25
Result: Each of the 4 people owes $25.50, of which $4.25 is the tip.
Frequently asked questions
How do I calculate a tip?
Multiply the bill by the tip percentage divided by 100. A 20% tip on an $85.00 bill is $85.00 x 0.20 = $17.00. Add that to the bill for a $102.00 total.
What is a standard tip percentage?
In the US, 15% to 20% is the common range for sit-down restaurant service, with 20% often considered standard for good service. Some people tip a bit less for counter service or a bit more for exceptional service; there is no single fixed rule.
How do I split a bill evenly among a group?
Add the tip to the bill to get the total, then divide by the number of people. For a $102.00 total split 4 ways, each person pays $25.50. This calculator does that division automatically once you enter the group size.
Should I tip on the pre-tax or post-tax amount?
Most etiquette guides suggest tipping on the pre-tax subtotal, though many people simply tip on the total printed at the bottom of the receipt for convenience. Either approach is common; enter whichever bill amount you prefer to tip on.
How do I tip if the group didn't order evenly?
This calculator assumes an even split, which is the simplest approach for most groups. If people ordered very different amounts, some groups instead calculate each person's own subtotal and tip percentage separately, then only use an even split for shared items.
