Tip Calculator

A tip calculator works out how much to tip on a restaurant bill, who owes what when splitting between guests, and the per-person total — including tax. It applies the percentage to the pre-tax subtotal (the standard convention in the US), supports custom tip rates, and rounds to a clean per-person figure.

restaurant Pre-tax tipping

US convention: tip is calculated on the pre-tax subtotal. The calculator follows this by default but you can override it.

lightbulb A real-world example — $87 dinner bill, 4 people

You and three friends had dinner. Pre-tax bill: $87. You want to leave 20% on the post-tax amount (in a 7.5% tax state) and split equally.

Result: Per-person total: $28.07. Tip on the post-tax amount = $18.71. With tax, the meal cost $93.53; tip brings the total to $112.24, divided 4 ways.

What this means: In the US, 18–22% is standard for sit-down service in 2026 (15% used to be the floor; current cost-of-living and tipping inflation have lifted that). Round up to the nearest dollar to keep change-handling simple. In Europe, 5–10% is standard and tax is already in the menu price.

Formula & methodology

Formula: Tip = Bill x (Tip% / 100); Total = Bill + Tip; Per person = Total / People

The calculator multiplies your bill by the chosen tip percentage, then divides the grand total by the number of people for an even split. US convention tips on the pre-tax subtotal, though many people tip on the total for simplicity. Use the rounding option to settle on a clean per-person amount.

Frequently asked questions

How much should I tip at a restaurant?
In the US, 15–20% of the pre-tax bill is standard for table service; 20%+ signals very good service. Counter service is optional.
Should I tip on the pre-tax or post-tax amount?
Etiquette says tip on the pre-tax subtotal, but tipping on the total only adds a few cents to a dollar and is perfectly acceptable.
How do I split a bill and tip evenly?
Add the tip to the bill first, then divide the grand total by the number of people. This calculator does both steps and can round to a tidy figure.
Do I tip on delivery if there's a delivery fee?
Yes. The delivery fee usually goes to the company, not the driver, so a 15–20% tip (minimum a few dollars) is still expected.
Is an 18% gratuity automatically added for large groups?
Many restaurants add an 18–20% auto-gratuity for parties of 6 or more. Check the receipt before adding a second tip.
