Work out the tip and split the check in a couple of taps. Enter the bill, pick a percentage, and say how many people are paying; the calculator shows the tip, the total, and each person's share to the cent, including who pays the extra penny when the total does not divide evenly. Round shares to whole dollars for cash, or tip on the pre-tax amount if you prefer — it all updates as you type and never leaves your browser.
For other everyday money math, the sales tax calculator adds or backs out tax from a price, the discount calculator works out sale prices and stacked coupons, and the percentage calculator answers any "what percent of" question. Hosting at home instead? The cocktail dilution calculator works out how much water and alcohol end up in a batched drink.
Frequently asked questions
How much should I tip?
In the United States, 15–20% of the bill is the usual range for table service at a restaurant, with 18–20% now common and 20% or more for excellent service or large, complicated orders. Bartenders often get $1–2 per drink or 15–20% of the tab, and delivery drivers 10–20% with a few dollars minimum. Counter service and takeout tips are optional. Customs differ widely abroad — in much of Europe and Japan service is included or tipping is uncommon — so check local norms when traveling.
Should I tip on the pre-tax or after-tax amount?
Etiquette guides generally say to tip on the pre-tax subtotal, since tax is not part of the service. In practice many people tip on the total because it is the number at the bottom of the receipt, and the difference is small — on a $100 meal with 8% tax, a 20% tip is $20 pre-tax versus $21.60 after tax. Turn on "Tip on the pre-tax amount" and enter the tax from your receipt to calculate it the etiquette-book way. Either choice is reasonable; the difference matters most on large bills.
How does splitting the bill work?
The calculator adds the tip to the bill and divides the total by the number of people. Money only comes in whole cents, so a total like $99.56 split three ways cannot be exactly equal: two people pay $33.19 and one pays $33.18, and the calculator tells you exactly that so the shares add back up to the penny. If people ordered very different amounts, it is fairer to calculate each person's share separately, running the calculator once per person with their own subtotal and the same tip percent.
What does rounding up or down do?
Rounding makes each person's share a whole dollar amount, which is easier for cash or payment apps. The bill never changes — only the tip absorbs the difference — so the calculator shows the effective tip rate after rounding. Rounding up is a common way to tip slightly more without doing math at the table. Rounding down is skipped if it would leave the total below the bill itself, because that would mean underpaying the restaurant.

Is there a quick way to calculate a tip in my head?
For 10%, move the decimal point one place left: $64.50 becomes $6.45. Double it for 20% ($12.90), or add half of the 10% figure for 15% ($6.45 + $3.23 = $9.68). For 18%, take 20% and subtract a tenth of it. The quick reference table under the calculator does all of these at once for your bill, so you can compare 15%, 18%, 20%, and 25% side by side, with a per-person column when you are splitting. Handy when the card reader asks you to pick a percentage.
