Tip on the pre-tax amount
Work out the tax on a bill with the Sales Tax Calculator, or take a percentage off a price with the Discount Calculator.
How the tip is worked out
The tip is a percentage of the bill: tip = bill × rate ÷ 100. Tip on the pre-tax subtotal and the base is the bill minus tax; tip on the total and the base is the whole check. The grand total is bill plus tip, and per person is that total divided evenly.
Tip
bill × rate
tip = base × rate ÷ 100
$50 bill @ 20% = $10 tip.
Split
total ÷ people
each = (bill + tip) ÷ people
$60 total ÷ 4 = $15 each.
- 1Tip on the pre-tax amount: If the $50 bill includes $4 of tax, a pre-tax 20% tip is on $46 = $9.20, not $10.

Splitting the tip fairly
Frequently asked questions
In the US, 15–20% of the bill is standard for sit-down table service: 15% for adequate service, 18% for good, and 20% or more for excellent. Counter service, takeout and coffee shops carry no obligation, though a dollar or two (or 10%) is appreciated. Norms differ sharply by country — in much of Europe and Asia a service charge is already included and tipping is minimal or optional.
Etiquette says tip on the pre-tax subtotal, because sales tax is a government charge, not part of the service. Tipping on the post-tax total is a little more generous — on a bill with 8% sales tax, a "20% tip" on the total is really about 21.6% of the food. Many restaurants print suggested tip amounts calculated on the after-tax figure, which is why the printed numbers can look high.
Add the tip to the bill first, then divide the grand total by the number of people. For a $60 bill plus a $12 tip ($72 total) split four ways, that is $18 each. Splitting the tip before adding it to the bill gives the same answer; splitting only the bill and having one person cover the whole tip does not.
Rounding bumps the grand total up to the next whole dollar (or a larger increment) so it is easy to pay or split, with the tip absorbing the difference. Rounding a $57.40 total up to $60 turns a modest tip into a slightly larger one — useful for cash, but it raises your effective tip rate, which the calculator shows.
No. A service charge (or "gratuity added for parties of 6+") is a mandatory fee set by the restaurant and shown on the bill; a tip is voluntary and set by you. When a service charge is already included you generally do not tip on top of it, though you can add a little extra for standout service. Always check the bill so you do not tip twice.

Method, assumptions & references
Methodology: tip = base × rate ÷ 100, where base is the bill (post-tax) or bill − tax (pre-tax). Total = bill + tip; per person = total ÷ people. Round-up bumps the total up to the next whole dollar and the tip absorbs the difference. All calculations run client-side; nothing is stored.
