Tip Calculator

What is a tip calculator?

A tip calculator is a tool that works out the gratuity and grand total on a bill and splits the cost between any number of people. Enter the bill amount, a tip percentage and your party size, and it instantly returns the tip, the total bill, the total per person, and the tip each person owes — so no one has to do mental maths at the table.

How do you calculate a tip?

Multiply the bill by the tip percentage, then divide by 100; add that to the bill for the total. The widget uses exactly these formulas:

• tip = bill × tip% ÷ 100
• total = bill + tip
• total per person = total ÷ people
• tip per person = tip ÷ people

The number of people is always rounded down to a whole number and is never less than 1.

Worked example 1

A $60.00 bill with an 18% tip, split between 2 people:

• tip = 60 × 0.18 = $10.80
• total = 60 + 10.80 = $70.80
• total per person = 70.80 ÷ 2 = $35.40
• tip per person = 10.80 ÷ 2 = $5.40

Worked example 2

An $85.50 bill with a 20% tip, split between 3 people:

• tip = 85.50 × 0.20 = $17.10
• total = 85.50 + 17.10 = $102.60
• total per person = 102.60 ÷ 3 = $34.20
• tip per person = 17.10 ÷ 3 = $5.70

Both results match the calculator above exactly. A fast mental shortcut for 20% is to find 10% (move the decimal one place left) and double it; for 15%, take that same 10% and add half of it again.

What is a normal tip percentage?

In the US, 15–20% of the pre-tax bill is the standard range for table service, with 18% a widely used default. The table below shows common percentages on a sample $90.00 bill.

Service quality	Tip %	Tip on $90	Total
Minimum / poor	10%	$9.00	$99.00
Adequate	15%	$13.50	$103.50
Good (default)	18%	$16.20	$106.20
Great	20%	$18.00	$108.00
Exceptional	25%	$22.50	$112.50

As a rough guide for other services in the US: 15–20% for food delivery and taxis/rideshare, $1–$2 per drink at a bar (or 15–20% of the tab), 15–20% for hairdressers, and $1–$5 per bag or night for hotel staff. Counter service and takeaway are discretionary.

How does tipping differ around the world?

Tipping norms vary dramatically, so the “right” percentage depends entirely on where you are.

Country / region	Typical restaurant tip	Notes
United States	15–20%	Expected; servers rely on tips as core income.
Canada	15–20%	Similar to the US.
United Kingdom	10–12.5%	Often added as an optional “service charge”.
France & much of Europe	0–10%	“Service compris” usually included; round up or leave small change.
Japan	0%	Not customary and can cause confusion or offence.
Australia & New Zealand	0–10%	Appreciated for great service, never required.

Before travelling, check whether a service charge is already printed on the bill — if it is, an additional tip is optional. When in doubt abroad, rounding up the total is a safe and polite default.

Should you tip on the pre-tax or post-tax amount?

The traditional etiquette is to tip on the pre-tax subtotal, because sales tax is not part of the service the staff provided. In practice many people tip on the post-tax total because it is simpler, and the difference is usually small. On a $50 meal with 8% tax, an 18% tip is $9.00 pre-tax versus $9.72 post-tax — a 72-cent gap. Enter whichever figure you prefer in the bill field. If you only have the post-tax total and want to back the tax out first, use the reverse sales tax calculator.

Real-world use cases

• Splitting dinner with friends: enter the shared bill and the headcount to get a clean per-person figure including tip.
• Group travel and events: quickly settle restaurant or bar tabs for larger parties.
• Budgeting a night out: preview the all-in cost before you decide where to eat.
• Service jobs and delivery: estimate a fair gratuity for drivers, stylists or movers.

For the everyday percentage maths behind these splits, the percentage calculator is a handy companion, and you can find more money tools on the finance category page.

Tips and common mistakes

• Tip on the right base. For strict etiquette, use the pre-tax subtotal, not the post-tax total, and tip on the full price even when you used a coupon.
• Watch for an included service charge. Adding a tip on top of a mandatory gratuity (common for large parties and abroad) means you may tip twice.
• Round sensibly. Rounding the final total up to a whole dollar is friendly; rounding down below the minimum norm is not.
• Splitting unevenly: this tool divides the total equally. For uneven shares, compute the total with tip first, then divide it by what each person ordered.
• Don’t forget tax in your budget. The calculator works on whatever bill you enter — it does not add tax for you.

Limitations and accuracy notes

This calculator divides costs evenly and rounds displayed values to cents for readability, so summing the rounded per-person amounts may differ from the total by a penny or two on awkward splits. Tipping is a social custom, not a fixed rule: regional norms, service charges, and personal judgement all matter. Treat the suggested percentages as guidance rather than obligation, and always check your bill for any gratuity that is already included.
