Tip and Split Calculator
Splitting a restaurant bill with a tip is quick arithmetic, but it is easy to fumble at the table. This calculator adds your chosen tip to the bill and divides the total evenly across your group, showing the tip amount, the grand total, the per-person share, and a per-person figure rounded up to the nearest dollar for cash. Enter the bill, tip percentage, and number of people, and everyone knows exactly what they owe.
Tip and split formula
Tip = bill * tip percentage / 100
Grand total = bill + tip
Per person = grand total / number of people
Per person, rounded up = round up (per person)
The tip is a percentage of the bill you enter, the total adds the two, and the split divides evenly. The rounded-up per-person figure makes cash splits tidy and nudges the effective tip slightly higher.
Worked example
A 60 US dollar bill, 18 percent tip, 3 people. Tip = 60 times 0.18 = 10.80. Grand total = 60 plus 10.80 = 70.80. Per person = 70.80 / 3 = 23.60. Rounded up, each pays 24.00, which collects 72.00 in total.
Tip and split: frequently asked questions
How do I calculate a tip and split the bill?
Multiply the bill by the tip percentage to get the tip, add it to the bill for the grand total, then divide the total by the number of people. For a 60 US dollar bill, an 18 percent tip is 10.80, the total is 70.80, and split among 3 people each owes 23.60.
Should I tip on the pre-tax or post-tax amount?
Customs vary, and it is your choice. Some people tip on the pre-tax subtotal, others on the post-tax total. Enter whichever bill figure you want to tip on; the calculator applies the percentage to the number you provide.
How can I round the per-person amount?
This calculator also shows the per-person amount rounded up to the nearest dollar, which is handy when splitting in cash. Rounding up slightly increases the total tip, which servers generally appreciate.
What is a standard tip percentage in the US?
In US table-service restaurants, 15 to 20 percent is common, with 18 percent a frequent default. Tipping norms differ by country and service type, so set the percentage that fits your situation rather than relying on a fixed figure.
