Split the Bill & Calculate the Tip: Easy Tip Calculator

The Tip Formula: Percent of the Pre-Tax Bill

Variables Explained

Tipping Scenarios, Worked Out

• 1Worked example: an $84.60 dinner bill at 18% → tip $15.23, total $99.83; split three ways that is $33.28 per person.
• 2Quick decision rule: 15% for standard service, 20% when it earns it — and read the bill first, since many restaurants add an automatic service charge for larger parties.
• 3For food delivery, 15-20% of the food value with a $3-5 minimum is the norm; takeout and counter pickup are optional, 0-10%.

Words on Your Receipt, Decoded

Gratuity

A voluntary payment (tip) given to service staff in appreciation of good service. In some countries, it is mandatory and added to the bill automatically.

Pre-tax Amount

The bill subtotal before sales tax is applied. The standard base for calculating tips.

Service Charge

A mandatory fee added to the bill by the restaurant, often for large groups. This is not the same as a voluntary tip.

How Much to Tip in the United States: Rates by Service, Decoded

Most tipping advice stops at “15–20% at restaurants,” but the rate that fits a sit-down dinner is the wrong number for a bar tab, a pizza delivery, or a haircut. The table below breaks the expected range down by service, and the notes after it cover the situations people actually argue about.

Moving inside the range

• Toward 20%: complicated orders, separate checks for a large group, attentive refills, or service under pressure — a packed patio in the rain is worth more than a quiet Tuesday.
• Toward 15%: standard competent service with nothing memorable in either direction.
• When something goes wrong: the kitchen is not the server’s fault, and a zero tip punishes the wrong person. Tip the server, then raise the problem with a manager.

Why US Tips Run 15–20%: The Wage System Behind the Percentage

The range is not politeness theater — in most of the United States it is the wage system. Federal law lets employers count a server’s tips toward a large part of the minimum-wage obligation, so in a tip-credit state a tip is not a bonus on top of a full wage. It is the wage.

Why the number keeps drifting upward

The customary restaurant tip sat at 15% for decades and has slid toward 20%, while the $2.13 cash wage has not moved since 1991. The percentage on the receipt is the part of a server’s paycheck that grows, and because it is a percentage, it scales with menu prices automatically — which is also why the “right” rate is a moving target rather than a fixed rule.

This is also why the country guide on this page looks the way it does. In much of Europe the service charge is built into the menu price by law or long custom, so a tip just rounds the bill. In the US the tip is the compensation itself — which is why the ranges are wider, the expectation firmer, and skipping it altogether lands differently than it does abroad.

Tipping Customs Around the World: A Country-by-Country Guide

Tipping customs vary dramatically around the world. Using the wrong amount can be seen as rude or wasteful. Here is a quick reference for common travel destinations.

When traveling, always check if a service charge is already included in the bill. In the US, tips are expected and essential for service workers' income. In many European and Asian countries, service is included and tipping is optional or discouraged. When in doubt, a small round-up or 5-10% is universally accepted.

Tip on Pre-Tax or the Full Bill? Five Cases That Change the Math

Most tip disagreements are not about generosity — they are about which number the percentage applies to. Five cases cover nearly every situation the calculator above can be fed:

1. Pre-tax is the convention; post-tax is common. Tipping on the pre-tax total is the textbook answer, but the difference is small: on a $60 bill at 8.5% tax, a 20% tip on the post-tax total adds about $1. Pick one as a table habit and stop recalculating each check.
2. Discounts and coupons: tip on the pre-discount value. The staff served a $100 meal even if a coupon brought the check to $60 — tip on $100. The pre-discount amount is what the service was actually worth.
3. Large-party auto-gratuity: check before you add. Many restaurants add 18% (sometimes 20%) automatically for parties of six or more, printed on the bill as a service charge. Adding your own 20% on top double-tips the table.
4. Delivery fees are not driver tips. The flat “delivery fee” on an app order mostly goes to the platform and the restaurant. Tip the driver separately: 15–20% of the food value, $3–5 minimum.
5. Rounding: pick a clean number. An 18% tip of $10.51 rounds to $10.50 or $11 without offending anyone. Clean numbers make card signatures and cash drawers easier, and nobody audits the difference.

Every case above reduces to the same arithmetic: choose the base amount, apply the rate, then split if the bill is shared. The calculator above handles any base and any percentage — the judgment calls listed here are the part it cannot decide for you.

Tip Splitting Guide: Fair Methods for Group Dining

Splitting the tip at a group dinner can be awkward. Different splitting methods work better for different situations. Here is a comparison of common approaches to ensure everyone pays their fair share.

For most group dining situations, the equal split method is the simplest and socially smoothest option — the difference usually amounts to just a few dollars per person. If the group has very different spending levels, use the per-person method. A good compromise: use the percentage split method where one person pays and everyone Venmos their share. Use this tip calculator to quickly compute individual shares.
