Tip Calculator

How this is calculated

Tip amount = bill × (tip percentage ÷ 100). Total = bill + tip. If splitting between multiple people, the total is then divided evenly by the number of people.

Choosing a tip percentage

Tipping norms vary by country, service type, and personal preference, but in the US a range of 15-20% is standard for restaurant service, with 18-20% common for good sit-down service.

Formula

Example: an $84.50 bill with an 18% tip gives a tip of $15.21 and a total of $99.71.

Common pitfalls

• Tipping on the wrong base — decide upfront whether you're tipping on the pre-tax subtotal or the total including tax, since it changes the result slightly.
• Uneven splits — dividing a total evenly assumes everyone ordered similarly; for very different orders, consider splitting by item instead.
• Forgetting an included service charge — some restaurants and large parties already add a gratuity or service charge to the bill, so check before adding a tip on top.

Tips

• For quick mental math, 10% of a bill is just moving the decimal point one place left; 20% is simply double that.
• Rounding the total up to a round number is a common way to simplify a tip without a calculator.

Frequently asked questions

How do you calculate a tip? Multiply the bill amount by the tip percentage divided by 100. For example, a 20% tip on a $50 bill is 50 × 0.20 = $10.

What is a standard tip percentage? In the US, 15-20% is the most common range for restaurant service, with 18-20% typical for good sit-down service and 10-15% sometimes used for counter service or takeout.

Should I tip on the pre-tax or post-tax amount? Most etiquette guides recommend tipping on the pre-tax subtotal, though many people simplify by tipping on the total bill including tax — either is commonly accepted.

How do I split a bill evenly between friends? Add the tip to the bill to get the total, then divide that total by the number of people — this calculator does both steps automatically when you enter the number of people.

Is tipping customary outside the US? Tipping norms vary widely by country — it's expected in the US and Canada, more modest (5-10% or rounding up) in much of Europe, and often not expected or even considered impolite in places like Japan.

What's a good tip for a $100 bill? At 18%, a $100 bill gets an $18 tip for a $118 total; at 20%, it's a $20 tip for a $120 total.

Do I tip on delivery orders the same as sit-down restaurants? Delivery tipping conventions are similar, typically 15-20% of the order subtotal, though some people add a bit more to account for weather, distance, or a delivery fee that doesn't go to the driver.

Worked examples

Example 1 — Dinner for two: $84.50 bill, 18% tip → $15.21 tip, $99.71 total, split between 2 people is $49.86 each.

Example 2 — Quick lunch, counter service: $18.00 bill, 10% tip → $1.80 tip, $19.80 total.

Example 3 — Group dinner, 6 people: $312.00 bill, 20% tip → $62.40 tip, $374.40 total, or $62.40 per person split 6 ways.
