How is the tip amount calculated?

The tip is bill multiplied by the tip percentage. A 100 bill at 18% is 100 × 0.18 = 18, so you pay 118 total. The presets cover the common restaurant tiers (15% for adequate, 18% standard, 20% good), and you can type any percentage or switch to a flat amount if you prefer to round the tip to a clean number like 20.

How do you split the bill evenly per person?

Divide the grand total (bill plus tip) by the number of people. A 118 total split four ways is 118 ÷ 4 = 29.50 each. The tool does this automatically and refuses to divide by zero, so if you set people to 0 it shows a prompt to enter at least 1 instead of an Infinity error.

What is the difference between 15%, 18% and 20% tips?

On a 100 bill they come out to 15, 18 and 20 in tip, for totals of 115, 118 and 120. The gaps look small per person but add up across a big table. In the US 18 to 20% is the normal range for sit-down service, 15% reads as just okay, and below that signals a problem with the meal.

Should I tip on the pre-tax or post-tax amount?

Etiquette says tip on the pre-tax subtotal, because tax is not part of the service. Many receipts and apps compute the suggested tip on the post-tax total instead, which nudges it slightly higher. On a 100 subtotal with 8 tax at 18%, pre-tax tip is 18.00 and post-tax tip is 19.44. Fill in the tax field and toggle the pre-tax switch to see both.

Why round each share up to a whole number?

Splitting 118 four ways gives 29.50, which means coins and awkward change. Round up and each person pays 30, the table pools 120, the 118 bill is covered, and the extra 2 becomes a little more tip. It keeps cash clean and guarantees you never come up short when everyone throws in their share.

How do I split a 100 bill with an 18% tip among 3 friends?

Tip is 100 × 0.18 = 18, total is 118, and 118 ÷ 3 = 39.33 each (one person can absorb the extra cent, or round up to 40 each and pool 120). Type 100 as the bill, tap the 18% preset, set people to 3, and the per-person line updates instantly. Copy the result or share the link so everyone sees the same number.

Split a restaurant check at the table

Dinner lands at 142.60 for five people and someone asks what everyone owes. Type the bill, tap 18%, set people to 5, and read the per-person line: total 168.27, about 33.65 each. Turn on round-up and it becomes 34 each, the table pools 170, the bill is covered, and the cents vanish. Share the link and nobody has to redo the math.

Settle a group bar tab fairly

A bar tab is 88 and the bartender expects a tip. Set the bill, choose 20%, and split among the four of you. The tool shows 105.60 total and 26.40 each, or 27 each rounded up. When the night gets loud and the arithmetic gets fuzzy, having the exact share on screen ends the "who owes what" debate before it starts.

Decide the tip without doing percentages in your head

You know you want to leave a good tip but blanking on 18% of 67.40 is easy after a few drinks. Punch in the bill, tap the preset, and the tip amount (12.13) appears instantly. Prefer a clean number? Switch to a flat tip and round it to 13 so the total comes to a tidy figure on the card slip.

Compare pre-tax and post-tax tipping

Your receipt shows the suggested tips computed on the post-tax total and it feels a touch high. Enter the bill, fill in the tax amount, and flip the pre-tax toggle to see the etiquette-correct number. On a 100 subtotal with 8 tax the pre-tax 18% tip is 18.00 versus 19.44 post-tax, so you can choose deliberately instead of by accident.

What this tool does

Free tip and split-the-bill calculator for restaurants, bars, group dinners and shared rides. Enter the bill, pick a tip (15%, 18%, 20% presets or a flat amount), set how many people are splitting, and it returns the tip in money, the grand total with tip on top, and what each person owes down to the cent. Choose whether the tip percentage applies to the pre-tax subtotal (US etiquette) or the full post-tax bill, since that choice quietly shifts every share. Turn on round-up and each person's slice snaps to the next whole unit so the pooled cash always covers the bill, with the slack landing as extra tip. One-click copy and a shareable URL reproduce your exact split for the group chat. Everything runs in your browser, 100% client-side, nothing uploaded.

Common pitfalls

Forgetting that a flat tip overrides the percentage. If you type a number into the flat-tip field, the percentage and its presets stop applying. Clear that field to go back to percent-based tipping, otherwise you wonder why tapping 20% changes nothing.
Splitting the bill before the tip instead of after. The per-person share should come from the grand total, not the raw bill. Splitting 100 four ways gives 25 each but leaves the tip uncovered. This tool always divides the bill-plus-tip total so each share already includes its slice of the gratuity.
Tipping on the post-tax total without meaning to. Many receipts pre-fill suggested tips on the taxed amount, which inflates the tip by a few percent of the tax. If you want the etiquette-correct figure, enter the tax and turn on pre-tax tipping so the percentage applies to the subtotal only.

Privacy

Every number here, the tip, the total, the per-person share and the round-up, is plain JavaScript that runs inside your browser tab. No bill amount, tip or split ever leaves the page and nothing is logged. The one caveat is the shareable URL, which encodes the bill, tip percent and people count in the query string, so a link you paste into a group chat records those numbers in the recipient server's access log. For a private amount, use the copy button and paste the text rather than sharing the URL.
