US convention tips on the pre-tax subtotal. Switching to “Tip After Tax” applies the tip rate to the tax-inclusive total, raising the gratuity by tax rate × tip rate.

How do you calculate the tip and split a restaurant bill evenly between everyone at the table?

The Tip & Bill Split Calculator turns a printed check into an exact per-person amount. Enter the subtotal, choose a tip percentage, add your local sales tax rate, and set the head count; the tool returns the tip, the tax, the grand total, and the individual share, plus a rounded-up collection scenario that shows how much surplus the group leaves behind when everyone pays a whole currency unit. Both US tipping conventions — tip on the pre-tax subtotal and tip on the tax-inclusive total — are supported through a single toggle.

What is the exact formula for tip, sales tax, and the per-person share?

Tax amount     = subtotal x tax rate
Tip base       = subtotal                     (Tip Before Tax mode)
Tip base       = subtotal + tax amount        (Tip After Tax mode)
Tip amount     = tip base x tip rate
Grand total    = subtotal + tax amount + tip amount
Per person     = grand total / number of people      (head count clamped to a 1 minimum)
Rounded share  = ceil(per person)
Collected      = rounded share x number of people
Surplus tip    = collected - grand total

Switching from Tip Before Tax to Tip After Tax raises the tip by exactly tax rate × tip rate of the subtotal. With an 8% tax and an 18% tip that is 1.44% of the subtotal — small on a single check, meaningful across a year of dining.

What does a $100 bill with an 18% tip and 8% sales tax look like step by step?

Step	Calculation	Tip before tax	Tip after tax
1. Subtotal	Printed food & drink total	$100.00	$100.00
2. Sales tax	100 × 8%	$8.00	$8.00
3. Tip base	Subtotal, or subtotal + tax	$100.00	$108.00
4. Tip	Tip base × 18%	$18.00	$19.44
5. Grand total	Subtotal + tax + tip	$126.00	$127.44
6. Split 4 ways	Grand total ÷ 4	$31.50	$31.86
7. Rounded up	ceil(share) × 4	$32.00 each	$32.00 each

How much should you tip in a US restaurant, a coffee shop, or for food delivery?

Service	Low	Customary	Generous
Full-service restaurant	15%	18–20%	25%
Bar / cocktails	10%	15–20%	25%
Counter service & coffee	0%	5–10%	15%
Food delivery	10%	15–18%	20%
Buffet with table service	5%	10%	15%

Why does rounding each share up to the nearest dollar change the effective tip percentage?

Rounding is applied per person and then multiplied by the head count, so the surplus grows with the size of the party. A group of ten rounding up an average of $0.60 each adds $6.00 of extra gratuity on top of the calculated tip. This calculator reports that surplus and the resulting effective tip rate so nobody is surprised by what actually lands on the table.

Do tipping expectations differ between the United States, the United Kingdom, and the Eurozone?

Substantially. US servers are frequently paid a tipped minimum wage, which makes an 18% to 20% tip part of their expected earnings. In the UK a 12.5% discretionary service charge is often printed on the check and no additional tip is expected. Across most of the Eurozone, service is included by law and rounding up or leaving 5% to 10% is considered generous. Switch the currency toggle to match the venue, then set the tip slider to the local norm rather than the US default.

Frequently Asked Questions

Standard US etiquette calculates the tip on the pre-tax subtotal, because sales tax is money collected for the state rather than value delivered by the server. On a $100 subtotal with 8% sales tax and an 18% tip, tipping before tax gives $18.00 in tip and a $126.00 grand total. Tipping after tax applies 18% to $108.00, which is $19.44, and produces a $127.44 grand total — a $1.44 difference. This calculator exposes both modes with an explicit toggle so the number you leave matches your intent.

The fair even-split method divides the grand total — subtotal plus tip plus tax — by the head count, rather than dividing only the food subtotal and asking one person to absorb the tip. For a $150 bill at 18% tip and 8% tax split four ways, each person owes $46.50 when tip is calculated before tax. When shares are uneven because of alcohol or shared appetizers, split the tip and tax proportionally to each person's subtotal rather than evenly, so heavy orderers carry their proportional share of both charges.

For full-service, sit-down restaurants the customary range is 18% to 20% of the pre-tax subtotal, with 15% treated as the low end for adequate service and 25% reserved for exceptional service or large-party attention. Counter service, coffee shops, and takeout typically fall between 0% and 10%. Many venues automatically add an 18% to 20% gratuity for parties of six or more; check the printed receipt before adding a second tip on top of an included service charge.

Applying it to the subtotal is the conventional and slightly cheaper approach, and it is what most etiquette guides recommend. Applying it to the tax-inclusive total is common in states with high sales tax and among diners who prefer a simple mental calculation off the receipt total. The mathematical relationship is fixed: tipping after tax increases the tip by exactly the tax rate multiplied by the tip rate — 8% tax with an 18% tip raises the tip by 1.44% of the subtotal.

Round each individual share up to the nearest whole currency unit and multiply by the head count. The difference between that rounded collection and the true grand total is the surplus, which normally becomes extra tip. For a grand total of $190.25 across four people, the exact share is $47.5625, the rounded share is $48.00, the collection is $192.00, and the surplus is $1.75. The itemized receipt panel in this calculator computes that surplus for you in real time.

When the party splits the bill evenly, yes — tax is a fixed percentage of the shared subtotal, so dividing it by the head count is exactly equivalent to charging each person tax on their equal portion. It only becomes unfair when individual orders differ substantially in price, in which case each person should pay tax on their own items. This tool models the even-split case and reports the per-person tax component explicitly so the arithmetic stays transparent.

Usually yes. An automatic gratuity of 18% to 20% listed as a separate line on the check is the tip, and additional tipping is optional rather than expected. A "service charge" or "kitchen fee" is legally distinct in many US states — it can go to the house rather than the server — so if the receipt shows a service charge instead of a gratuity, a customary tip on top is still appropriate. Enter 0% tip in this calculator when gratuity is already included and you want to split only bill and tax.
