Tip Calculator

You and three friends just finished dinner and the bill comes to $75. The service was good, so you decide to tip 20%. That's a $15 tip, bringing the grand total to $90 - and split four ways, each person owes $22.50. This tip calculator does exactly that math instantly: enter the bill, pick a tip rate, choose how many people are paying, and it shows the tip, the total, and what each person pays.

How the tip is calculated

The formula is simple percentage math:

So a $75 bill at 20% gives a tip of 75 × 20 ÷ 100 = $15, a total of 75 + 15 = $90, and split four ways that's 90 ÷ 4 = $22.50 per person. Because it's a percentage, the same tip rate works at any price point - the dollar amount just scales with the bill.

How much to tip in the US

In the United States, tipping is a customary part of paying for service. Typical ranges are:

• Sit-down restaurants: 15%-20% (18%-20% for good service).
• Bars: roughly $1-$2 per drink, or 15%-20% of the tab.
• Food delivery: 10%-20%, with a few-dollar minimum.
• Taxis & rideshare: 10%-20% of the fare.
• Hair, nails & spa: 15%-20% of the service price.

These are conventions, not rules - tipping is voluntary, and you can always adjust up for excellent service or down when service falls short.

Tipping on the subtotal vs. the total

Whether you tip on the pre-tax subtotal or the after-tax total is a matter of preference. Since sales tax isn't part of the service, many people tip on the subtotal; tipping on the full total simply yields a slightly larger tip. This calculator applies your chosen percentage to whatever bill figure you enter, so type the subtotal if you'd rather tip pre-tax. If you need to work out the tax portion first, the Sales Tax Calculator separates the subtotal from the tax so you can tip on whichever figure you choose.

The size of that gap depends entirely on your local sales-tax rate. In a state with no sales tax there is no difference at all between the two methods. In a high-tax area at around 9%, tipping 20% on the post-tax total instead of the subtotal adds roughly 1.8% extra to the bill - on a $100 subtotal that is about $1.80 more in tip. It is rarely enough to argue about, which is why both approaches are considered perfectly acceptable in practice.

Splitting the bill evenly

To divide a bill, the calculator adds the tip first and then splits the grand total, so everyone covers their share of both the food and the gratuity. The comparison table also shows the per-person cost at 15%, 18%, 20% and 25%, which is handy when the group wants to agree on a rate before paying. For uneven splits - where people ordered very different amounts - calculate each person's share of the bill first, then apply the same tip percentage to each.

How to use this tip calculator

You only need three numbers to get an exact result. Work through the fields in order:

1. Bill amount: enter the figure you want to tip on. Type the pre-tax subtotal if you prefer to tip on the food only, or the post-tax total if you would rather tip on the whole check.
2. Tip percentage: tap one of the quick buttons (15%, 18%, 20% or 25%) or type your own rate. The tip and total update the moment you choose.
3. Number of people: set how many are splitting the check. Leave it at one if you are paying alone, or raise it to see the per-person bill, tip and total.

Read the tip and grand total at the top, then use the per-person figures and the 15%-25% comparison to settle on an amount everyone is comfortable with before the card goes down.

Who this calculator is for

Anyone who wants the gratuity math done for them in a second can use it. It is especially handy for:

• Diners splitting a check with friends or coworkers who want a fair, even share of the food and the tip.
• Travelers and visitors to the US who are not sure what the local tipping norm is and want a quick sanity check.
• Anyone paying for delivery, a haircut, a taxi or a bar tab who wants to leave a reasonable amount without doing percentage math at the counter.
• Budgeters estimating the real cost of a meal out, since the tip can add 15%-25% to the menu price.
• Event hosts checking gratuity on a catering or large-party bill, where an automatic service charge may already apply.

A second worked example: splitting unevenly

Say four people get dinner and the subtotal is $120, but the orders were not equal: two people had $40 of food each and two had $20 each. If you split a flat 20% tip and the total evenly, everyone pays $36 - which overcharges the lighter eaters. To split fairly, apply the tip to each person's share. The 20% tip is $24, so each diner adds 20% to their own food: the $40 diners pay $48 each and the $20 diners pay $24 each. The bill and the gratuity both scale to what each person actually ordered, and the four shares ($48 + $48 + $24 + $24) add back up to the $144 grand total.

Key tipping terms explained

• Gratuity: another word for a tip - a voluntary payment for service on top of the bill.
• Automatic gratuity: a tip the restaurant adds for you, commonly 18%-20% for large parties. It appears as a line item on the check.
• Service charge: a mandatory fee set by the business. Unlike a tip, you do not choose it, and it may not all go to your server.
• Subtotal: the cost of the food and drinks before sales tax is added.
• Tip pooling: an arrangement where servers, bussers and bartenders share tips so the whole team is paid for the service.
• Tipped minimum wage: a lower base cash wage some tipped workers are paid, on the assumption that tips make up the rest of their income.

What changes how much you should tip

The "right" tip is not a fixed number - a few factors push it up or down within the customary range:

• Quality of service: attentive, friendly service earns the top of the range; poor service can justify less.
• Type of venue: full table service is tipped more than counter or quick-service spots, where tipping is lighter or optional.
• Group size: large parties are often charged an automatic gratuity, so you may not need to add more.
• Difficulty of the request: special accommodations, large orders or extra effort are often recognized with a higher tip.
• Local custom: tipping norms vary by region and country - what is standard in the US may not apply elsewhere.

Quick tip reference: common bills at common rates

It helps to have a feel for the dollar figures before you reach for a calculator at the table. The table below shows the tip and the grand total for typical bill sizes at the four standard US rates. Because tipping is pure percentage math, you can scale any of these up or down - double the bill and the tip doubles too.

These are tip amounts only - add them to the bill for the grand total. For a $100 bill at 20%, that is a $20 tip and a $120 total; split three ways, each person pays $40. The calculator does this rounding to the cent and handles awkward numbers (like a $73.40 bill) instantly, but the table is useful for the mental ballpark you want before the check even arrives.

Tipping when you order at a screen or counter

Tablet and card-reader prompts have changed how often people are asked to tip. Counter-service cafes, food trucks, and self-checkout screens now frequently present preset buttons - sometimes starting at 18% or higher - for transactions where tipping was historically uncommon. There is no obligation to accept the default. For a barista who pours a coffee, many people tip a flat dollar or a smaller percentage, or decline entirely, and reserve the full 15%-20% for sit-down table service where a server attends to you throughout the meal.

The pressure of an on-screen prompt with a watching cashier is real, but the customary logic still applies: the more personal, sustained, and skilled the service, the higher the tip. A good rule of thumb is to ask yourself what the worker actually did. Carrying plates, refilling drinks, splitting checks, and managing a table for an hour warrant a percentage tip; ringing up a pre-made item at a register generally does not. If you do want to leave something at the counter, you can type a custom amount into this calculator to see exactly what a 10% or flat-dollar tip looks like on your order.

Tipping when you travel outside the US

The 15%-20% restaurant norm is distinctly American and does not transfer cleanly abroad. In much of Europe, a service charge is frequently built into the menu prices or added as a line item, and locals leave only small change or round up to the nearest euro for good service. In Japan and South Korea, tipping is not customary at all and can even cause confusion or be politely refused, because excellent service is considered standard. In many parts of Australia and New Zealand, staff are paid a full living wage, so tipping is appreciated but never expected.

Before you travel, check the convention for your destination rather than defaulting to US habits. Over-tipping in a no-tip culture is not offensive, but it is unnecessary, and under-tipping in a country where it is expected (such as leaving nothing in a US-style sit-down restaurant abroad) can come across as rude. When you are unsure, looking at your receipt for a "service" or "servizio" line tells you whether the gratuity is already covered. This calculator assumes US conventions, so treat its suggested 15%-25% range as a starting point only when you are dining in another country.

Should you tip on the rounded or exact amount?

Once the calculator gives you a precise tip - say, $13.47 - you have a choice about how to actually leave it. Many people round to a clean number to make the total easy to settle: rounding that tip up to $14, or rounding the grand total to the nearest dollar or five dollars. Rounding up is a small, generous gesture that costs only cents and saves everyone the fiddly math when paying cash. Rounding the per-person split up also avoids the classic problem where four people each put in their share and the total comes up a dollar short.

If you are paying by card, you can enter the exact figure the calculator shows, or write a rounded total on the tip line. A practical habit is to decide your total first - "I want this to come to an even $90" - and let the tip absorb the rounding. Either way, the calculator's job is to give you the accurate baseline; whether you round up from there is a matter of convenience and generosity, not a rule.

Why tipping matters for service workers

Tipping is more than etiquette in the United States. Under the federal Fair Labor Standards Act, employers may take a "tip credit" and pay tipped employees a cash wage as low as $2.13 per hour, provided tips bring the worker to at least the full federal minimum wage of $7.25; if they do not, the employer must cover the gap. Several states require a higher cash wage or ban the tip credit entirely. Because of this structure, the tip you leave at a sit-down restaurant is often a meaningful part of the server's actual pay, not just a bonus. Knowing the exact amount - which this calculator gives you - makes it easy to leave a fair tip without overthinking the math.

Limitations and assumptions

This is a convenience tool, so keep a few things in mind:

• It applies your percentage to whatever bill figure you enter - it does not know whether that number includes sales tax, so you decide what to tip on.
• It splits the total evenly by the number of people; for uneven orders, apply the tip to each person's share as shown above.
• It does not detect an automatic gratuity or service charge already printed on your receipt - always check the check first.
• It assumes US tipping conventions; norms differ widely in other countries, where service is often included.
• Tipping is voluntary, so treat the suggested rates as a starting point, not a rule.
