Tip calculator guide
The tip calculator works out the gratuity on a bill, adds it to the total, and divides the result evenly among the people paying. Enter the bill amount, the tip rate you intend to leave, and the number of people, and the headline figure is what each person owes including their share of the tip. The rows beneath show the tip alone, the grand total, and the tip per person, which is handy when the bill itself is being paid by card and the tip in cash. It is designed for restaurants, delivery, taxis, and salons, anywhere a percentage gratuity is customary. The calculator does not add sales tax or a service charge already printed on the bill, and it does not decide whether to tip on the pre-tax or post-tax amount; enter whichever subtotal you want the percentage applied to. Amounts are shown in your selected currency and rounded to the cent.
Tip = bill × tip rate ÷ 100. Total = bill + tip. Per person = total ÷ people. Tip per person = tip ÷ people.
Worked example with the defaults: bill $80, tip rate 18%, 2 people. Tip = 80 × 18 ÷ 100 = $14.40. Total = 80 + 14.40 = $94.40. Per person = 94.40 ÷ 2 = $47.20, which the calculator displays as the amount per person including tip. Tip per person = 14.40 ÷ 2 = $7.20. Changing the rate to 20% gives a $16.00 tip, a $96.00 total, and $48.00 each.
The bill is entered in your selected currency (the default display is USD) and the tip rate as a whole-number percentage, so 18 means 18%. People is a head count and is rounded to a whole number with a minimum of 1. Results are formatted to two decimal places, so a split that does not divide evenly, such as $94.40 among 3 people, shows $31.47 each and the cents may not sum exactly to the total.
The result follows directly from the numbers you entered, so its accuracy is the accuracy of those inputs. The most common source of a surprising answer is a mismatch between the question you meant to ask and the one the calculator answered, so re-read the field labels if the figure looks wrong. The formula is shown above so you can check the arithmetic yourself. On this page the figure rests entirely on bill amount, tip rate and people, so start there if the tip calculator returns something you did not expect.
Good to know: if the bill already lists a service charge or “gratuity included”, adding a full tip on top double-pays. Tipping on the post-tax total gives a slightly larger tip than tipping on the pre-tax subtotal; either is common, but be consistent. When the split leaves fractions of a cent, round each share up so the total is covered. Tipping customs vary widely by country; the default 18% reflects common US practice and may be inappropriate elsewhere.

How it works
Calculate a tip and split the total bill between people. This tool explains the calculation so you can adjust the assumptions to match your situation.
Worked example
With Bill amount = 80 $ · Tip rate = 18 % · People = 2 → $47.20 (amount per person including tip). Change an input above and this example updates with your numbers.
Common questions
$14.40. Multiply 80 by 0.18, or take 10% ($8) plus 8% ($6.40). The total with tip is $94.40, and split between 2 people each pays $47.20, of which $7.20 is tip.
Take 10% by moving the decimal point one place left, then adjust: on $80, 10% is $8, so 20% is $16 and 15% is $12. For 18%, add 10% and 8% (which is 0.8 × $8 = $6.40) to get $14.40.
Both conventions exist. Tipping on the pre-tax subtotal is the traditional etiquette advice; many people simply tip on the final total for convenience. Enter whichever amount you choose as the bill; the difference on an $80 subtotal with 8% tax is about $1.15 at 18%.
Add the tip to the bill, then divide by the number of people. $80 plus an 18% tip is $94.40, which is $47.20 each for two or $31.47 each for three (round up so the total is covered).
In the United States, 15% to 20% is typical at sit-down restaurants, with 18% a common middle value. Counter service, delivery, and other countries follow different norms, so adjust the rate to local custom.
