Tip, total & split the bill

Key Takeaways & Benchmarks

✓Tip = bill × tip percentage; total = bill + tip.
✓15–20% is the US standard for table service; 20%+ for great service.
✓Etiquette says tip on the pre-tax amount.
✓Check for automatic gratuity on large parties before adding more.
✓Per person = total with tip ÷ number of people.

How tipping math works

A tip is a percentage of the bill added as a gratuity for service. The arithmetic is straightforward — bill × tip percentage — but the social math of who pays what at a shared table is where most people reach for a calculator.

Splitting evenly is the path of least resistance: total with tip divided by headcount. It keeps friendships intact and gets everyone out the door faster than itemising six separate orders.

The formula

"Tip = bill × (tip % ÷ 100)"

"Total = bill + tip"

"Per person = total ÷ number of people"

Worked example

Dinner for four comes to $120. At 20%, the tip is $24 and the total is $144 — $36 per person. Drop the tip to 15% and each person pays $34.50 instead; the $1.50 difference per person is the entire cost of being generous.

Now try a 10% takeout scenario on a $45 order: the tip is $4.50 and the total $49.50. Small numbers, but they add up meaningfully for workers who depend on gratuities.

Tipping tips

▸Tip on the pre-tax subtotal, not the tax-inclusive total.
▸Check for automatic gratuity on large parties before adding more.
▸Round up to a clean number when splitting — nobody wants to Venmo $25.08.
▸Tip delivery drivers 15–20%; they pay their own fuel and maintenance.
▸When travelling, learn local norms first — tipping culture varies enormously by country.

Frequently asked questions

How much should I tip at a restaurant?+

In the US, 15% is the baseline for adequate table service, 18–20% is standard for good service, and 20–25% rewards exceptional service. For bars, $1–2 per drink is customary. Tipping norms differ sharply by country — in Japan tips can offend, while in much of Europe a small rounding-up suffices because service charges are often included.

Do I tip on the pre-tax or post-tax amount?+

Etiquette says pre-tax: tax is a government levy, not part of the service you received. In practice the difference is small — on a $100 bill with 8% tax, tipping 20% on pre-tax vs post-tax differs by $1.60. When in doubt, the generous option costs little.

How do you split a bill evenly?+

Add the tip to get the total, then divide by the number of people. On an $85 bill with an 18% tip ($15.30), four people each owe $25.08. This calculator does it in one step. For uneven orders, have each person calculate their share of the subtotal plus a proportional share of tax and tip.

Should I tip on takeout or delivery?+

For takeout, 10% is a nice gesture though not obligatory in the US. For delivery, 15–20% (minimum a few dollars) is standard since drivers cover their own fuel and vehicle costs. During bad weather or for large, complicated orders, tipping toward the higher end is appreciated.

What is a good tip percentage for large groups?+

Many US restaurants add an automatic gratuity — often 18–20% — for parties of 6 or 8+. Check the bill first so you don't double-tip. If no auto-gratuity is listed, 20% is a safe choice for a group that kept the server busy.

How do I calculate a tip quickly in my head?+

Move the decimal one place left for 10%, then double it for 20%. On $64: 10% is $6.40, so 20% is $12.80. For 15%, take 10% and add half again ($6.40 + $3.20 = $9.60). It takes seconds once it becomes habit.

Is it okay to tip less for bad service?+

Tipping 10% signals dissatisfaction without stiffing the server entirely — but consider that slow service is often the kitchen's fault, not your server's. If something was genuinely wrong, a calm word with the manager usually accomplishes more than a punitive tip.

Do I need to tip if a service charge is already included?+

No — a service charge is the tip, already distributed (in theory) to staff. Check whether it says 'service charge' versus 'gratuity'; both mean you don't need to add more unless service was outstanding. This differs from sales tax, which never counts as a tip — the VAT / GST Calculator can separate tax from the bill if you want to tip on the pre-tax figure.
