Step-by-Step Guide
Enter the bill subtotal (the pre-tax amount if your bill shows tax separately, or the full total if you want to tip on the post-tax amount — local customs vary). Select a tip percentage using a preset button (10%, 15%, 18%, 20%, or 25%) or use the slider to fine-tune. Set the number of people sharing the bill and the calculator shows the tip amount, the grand total, and each person's exact share.
Tipping on pre-tax vs. post-tax amount
Convention in the United States is to tip on the pre-tax subtotal, but many people tip on the post-tax total out of habit or simplicity. The difference is small — on a 9% sales tax rate, tipping 20% on the total rather than the subtotal adds about 1.8% to the tip — but enter whatever amount you prefer to calculate against.
$85 bill subtotal with 18% tip, split among 4 people: tip = $85 × 0.18 = $15.30; grand total = $100.30; per-person share = $100.30 ÷ 4 = $25.08 each. If someone wants to leave a round $26 per person, the effective tip percentage works out to about 22% — useful context when deciding to round up for good service.

How do I calculate tip?
Tip is a percentage of the bill you add to thank your server. To calculate it, multiply the bill by the tip percentage expressed as a decimal: a $60 bill with a 20% tip is $60 × 0.20 = $12 tip. The grand total is $60 + $12 = $72. This calculator does that arithmetic instantly including the per-person split.
What is the standard tip percentage for a restaurant?
In the United States, 15% is considered the minimum for adequate service, 18–20% is standard for good service, and 25% or more reflects exceptional service. Coffee shops, counter service, and takeout are typically tipped less (10% or a small flat amount), while full-service restaurants and bartenders expect at least 18–20%. Tipping customs vary internationally — in many countries tipping is not customary or is done differently.
How do I split a bill evenly?
Enter the bill total and tip, then set the number of people to the split count. The per-person share is (bill + tip) ÷ people. If individuals ordered very different amounts, you may prefer to calculate each person's portion separately based on their own order — this calculator assumes an even split.
Should I tip on the pre-tax or post-tax total?
Etiquette advice varies. Tipping on the pre-tax subtotal is technically more precise, but many diners tip on the total for simplicity. The dollar difference is small — on a $100 bill with 8% tax, the tip on $100 vs $108 differs by only $1.60 at 20%. Enter whichever amount is on your receipt that you want to tip on.
The awkward math moment at the end of every group meal
The bill arrives. Someone says 'let's add 20% and split it.' Someone else pulls out a phone. A third person says 'but I only had a salad.' Ten seconds later the table is doing four separate calculations, nobody agrees on the total, and the person who offered to figure it out regrets volunteering. The problem is not that tip math is hard — it is that it is just fiddly enough, and under enough social pressure, that small errors are common.
Why stacked discounts and tips are both percentage problems
A tip is a percentage applied to a base amount. The only arithmetic question is: which base? In the US, the technically correct base is the pre-tax subtotal — you are tipping on the service and food, not on the tax the government collects. But many people tip on the post-tax total out of habit or simplicity, and the practical difference is small. On a $100 bill with 8% tax, tipping 20% on $100 versus $108 is a difference of $1.60. What matters more is that everyone at the table uses the same base and the same percentage, or the split amounts will not add up.
What "even split" actually means — and when it breaks
Even split divides the total (including tip) equally among all people. It is the fastest calculation and works well when orders were roughly similar. It breaks down when one person ordered a $9 salad and another ordered a $45 steak and a bottle of wine. The fair alternatives are an itemized split (each person pays for their own items plus a proportional share of tax and tip) or a compromise where heavy orderers round up voluntarily. This tool handles the even-split case because it covers the vast majority of group meals — the itemized case is a spreadsheet problem, not a calculator problem.
The mental math shortcut worth knowing
To calculate 20% of any bill in your head: move the decimal one place left to get 10%, then double it. A $73 bill: 10% is $7.30, double it to $14.60 tip, total $87.60, split four ways is $21.90 each. For 15%: take 10% and add half again. These shortcuts are faster than reaching for a phone and produce the same result to the nearest dollar.
