Answer: Enter the bill amount, tip percentage, and number of people to get the tip amount, total bill, and per-person share instantly.
A tip calculator splits the bill and gratuity across any number of people, computing per-person totals and tip percentages instantly.
Calculate tip and split the bill
This tip calculator computes the tip amount and total bill for any tip percentage, and splits the result across any number of diners. Enter the bill, choose a percentage, set the party size, and the per-person amount updates instantly — no mental math at the table.
The arithmetic is simple: tip = bill × percentage ÷ 100, total = bill + tip, per person = total ÷ party size. On a $64.00 bill with an 18% tip, the tip is $11.52, the total is $75.52, and splitting four ways costs $18.88 each. The value of the tool is speed and consistency, not complexity.
Tipping norms vary by country and service. In the United States, table-service restaurants commonly see 15–20% of the pre-tax bill, with 18–20% now the most typical range in surveys of diner behavior; 15% reads as the floor for acceptable service and 20%+ for excellent service. Bartenders often get $1–2 per drink or 15–20% of the tab. Food delivery drivers commonly receive 10–15%, and rideshare apps default to similar percentages.
Many other countries do not share this convention. Japan views tipping as unnecessary and can even find it awkward; much of Europe includes service in the bill, with rounding up or leaving a few euros as a courtesy. When traveling, checking the local norm first avoids both undertipping where it matters and overtipping where it confuses.
The conventional base for a restaurant tip is the pre-tax subtotal, though many people simply tip on the total — the difference on a $60 bill with 8% tax is about $1 at 20%, well within rounding tolerance. The clearer cases are discounts and gift cards: etiquette writers generally recommend tipping on the pre-discount value, because the server did the same work whether you used a coupon or not.
For wine and expensive bottles, practice varies. A common guideline is 15–20% on the bottle as with food, though some etiquette sources suggest capping the tip on very expensive bottles since pouring effort does not scale with price. Whichever rule you follow, applying it consistently is what the calculator makes easy — enter your chosen base and percentage and the math is exact.
| Bill | 15% tip | 18% tip | 20% tip | Total @20% |
|---|---|---|---|---|
| $20.00 | $3.00 | $3.60 | $4.00 | $24.00 |
| $35.00 | $5.25 | $6.30 | $7.00 | $42.00 |
| $50.00 | $7.50 | $9.00 | $10.00 | $60.00 |
| $64.00 | $9.60 | $11.52 | $12.80 | $76.80 |
| $85.00 | $12.75 | $15.30 | $17.00 | $102.00 |
| $120.00 | $18.00 | $21.60 | $24.00 | $144.00 |
The table below shows tip and total for a range of bill sizes at 15%, 18%, and 20%. It doubles as a sanity check for the calculator: pick your bill row, find your percentage column, and compare against the tool's output.
For parties, most US restaurants add an automatic gratuity — commonly 18–20% — for tables of six or more; that policy is set by the restaurant, not law, and should appear on the menu. If an automatic gratuity is already on the check, your group does not owe an additional tip unless you choose to add one for standout service.
How much should I tip at a restaurant in the US?
The customary range for table service is 15–20% of the bill, with 18–20% typical for good service and 15% generally read as the minimum acceptable. For excellent service many diners go above 20%. The calculator makes any percentage exact, including awkward bill amounts where mental math stumbles.
Should I tip on the tax or the pre-tax amount?
Convention says the pre-tax subtotal, since tax is not revenue for the restaurant or server. That said, tipping on the after-tax total is common practice and the difference is small — on a $60 bill with 8% tax, the gap at 20% is 96 cents. Either choice is defensible; consistency matters more.
How do I split the bill and tip across a group?
Compute the tip on the full bill, add it to get the grand total, then divide by the number of people. This keeps everyone's share proportional to the whole bill. If some diners ordered much more than others, itemizing first and then applying the tip percentage per person is the fairer method.
Do I tip on the amount before a discount or coupon?
Etiquette guidance is to tip on the pre-discount total. The server performed the same service regardless of a coupon, Groupon, or comped item, so the conventional practice bases the tip on what the bill would have been.
Is tipping expected in other countries?
It varies widely. Japan and South Korea do not have a tipping culture and staff may initially refuse extra money. Much of Europe includes a service charge, with small rounding-up as a courtesy. Canada and the US are the strongest tipping cultures; checking local norms before traveling avoids awkward moments on both sides.
What is an automatic gratuity?
Many US restaurants add a mandatory service charge — commonly 18–20% — for larger parties, often six or more guests. It appears as a line item on the check, and where it applies, the tip is already included; an extra tip is optional. Unlike a voluntary tip, automatic gratuities may be treated as wages rather than tips under IRS rules for the restaurant.
