Tip Calculator
A tip is a gratuity added to a bill, calculated by multiplying the bill total by a chosen tip percentage — 15-20% is customary for restaurant service in the United States. This calculator finds the tip amount and final total, and splits the bill evenly across any number of people.

How is a tip calculated?
Tip = Bill Amount × (Tip % ÷ 100)
Multiply the bill amount by the tip percentage (as a decimal) to get the tip. Add the tip to the bill for the total. Divide by the number of people to get each person's share. Suggested tips are calculated at standard percentages (15%, 18%, 20%, 25%) for quick comparison.
How do you calculate a tip step by step?
Example 1: Dinner for Two
Problem:Your dinner bill is $85.00 and you want to leave a 20% tip, split between 2 people.
Solution:Tip amount: $85.00 × 20% = $17.00 Total with tip: $85.00 + $17.00 = $102.00 Per person: $102.00 ÷ 2 = $51.00 Tip per person: $17.00 ÷ 2 = $8.50
Result:$17.00 tip | $102.00 total | $51.00 per person
Example 2: Group Dinner
Problem:A group of 6 has a $240 bill and wants to tip 18%.
Solution:Tip amount: $240.00 × 18% = $43.20 Total with tip: $240.00 + $43.20 = $283.20 Per person: $283.20 ÷ 6 = $47.20 Tip per person: $43.20 ÷ 6 = $7.20
Result:$43.20 tip | $283.20 total | $47.20 per person
What else do people ask about tipping?
How much should you tip at a restaurant?
In the United States, the standard tip at a sit-down restaurant is 15-20% of the pre-tax bill. For excellent service, 20-25% is common. For counter service or takeout, 10-15% is appropriate but not expected. Fine dining restaurants may expect 20-25%. Always tip on the pre-tax amount, not the total after tax. If you received poor service, 10% is the minimum; speak to a manager rather than leaving no tip.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts recommend tipping on the pre-tax subtotal. Sales tax varies widely (0-10%+) and is not part of the service provided. However, tipping on the post-tax amount is also acceptable and simpler. The difference is usually small — on a $100 bill with 8% tax, tipping 20% on pre-tax ($20) vs post-tax ($21.60) is only $1.60. Many people tip on the rounded total for convenience.
How do you split the bill fairly with a group?
The simplest method is dividing the total (including tip) equally among all diners. If people ordered vastly different amounts, you can split proportionally — each person tips 20% on their individual order. Apps like Splitwise can help track uneven splits. For large groups (6+), many restaurants add an automatic 18-20% gratuity, so check your bill before adding additional tip.
What is the tipping etiquette for delivery and other services?
Services that produce a bill are usually tipped as a percentage of it, in the same range as restaurant service: delivery, rideshare and taxi rides, hair and beauty appointments, bar tabs and guided tours all work this way, and Tip Calculator handles them directly. Services with no bill — hotel housekeeping, a valet, a porter, a mover, a barista, a counter-service order — are tipped as a flat amount instead, and there is no single correct figure: what people leave depends on the local cost of living, how many staff shared the work, how long it took and how much was carried. For those, pick an amount that reads as meaningful money where you are, tip per person rather than per group where several people served you, and carry small bills so you are not forced to round in either direction. Etiquette guides such as the Emily Post tipping guide linked in the references publish current customary amounts by service and are worth checking rather than guessing, particularly for delivery, where a percentage of a small order can fall below what the driver's trip actually costs — a floor amount matters more than the percentage there.
Do you tip differently in other countries?
Tipping customs vary significantly worldwide. In Japan, tipping is considered rude and may be refused. In most of Europe, a 5-10% tip is appreciated but not expected — service charges are often included. In Australia and New Zealand, tipping is not customary but rounding up is appreciated. In Canada, 15-20% is standard (similar to the US). In many Middle Eastern and South American countries, 10-15% is appropriate. Always research local customs before traveling.
How do I work out a 15% or 20% tip in my head?
Move the decimal point one place left to get 10%, then scale from there. On an $85 bill, 10% is $8.50, so 20% is double that at $17.00, and 15% is $8.50 plus half of $8.50, which is $12.75. For 18%, take the 20% figure and subtract a tenth of it: $17.00 minus $1.70 gives $15.30. Rounding the result up to the next whole dollar costs very little and makes both the arithmetic and the final total tidier.
What is the difference between a tip and a service charge?
A tip is discretionary — you decide whether to leave one and how much. A service charge or automatic gratuity is a mandatory line the restaurant adds to the bill, commonly on parties of six or more, at a rate the house sets rather than one you choose. Because both appear near the bottom of a receipt, read the itemised lines before filling in the tip box, or you can easily pay twice on the same meal. How a service charge is distributed among staff depends on the venue and on local rules, so ask if it matters to you.
Should I tip on the discounted price or on the original price?
Tip on what the meal would have cost before the coupon, voucher, gift card or comped dish. Taking the order, running the food and clearing the table takes the same effort whatever you paid, and the percentage is only a shorthand for that work. If a $60 meal is halved to $30 by a promotion, 20% of the original $60 is $12 rather than $6. The same reasoning applies to a dish removed from the bill after a kitchen mistake: the service still happened.
What is tip pooling, and does it change how much I should leave?
In many restaurants the server does not keep the whole tip. Front-of-house staff either pool tips and divide them, or the server tips out bussers, food runners and bartenders — and that tip-out is frequently calculated from the server's total sales rather than from the tips actually collected. Under that arrangement, leaving nothing on a large bill can leave the server paying to have served you, because the tip-out is still owed. If service was genuinely poor, raise it with a manager rather than only cutting the tip.
How do I work backwards from a total that already includes the tip?
Divide the total by 1 plus the tip rate written as a decimal. A $102.00 charge that already includes a 20% tip came from an $85.00 bill, since 102 divided by 1.20 is 85, and the tip is the $17.00 difference. The same algebra sets a target total: to bring an $85 bill up to a round $100 you need $15 of tip, and 15 divided by 85 is 0.176, or about 17.6%, which is a perfectly normal amount to leave.
