How to read this estimate

Tip = bill x tip% / 100, added to the bill and divided evenly across the group. Many diners tip on the pre-tax amount for a conservative gratuity; auto service charges, if present, usually replace a manual tip. US customs of 15-20% are common for table service.

What is a Tip & Bill Split Calculator?

A tip and bill split calculator computes the gratuity on a bill, the final total including tip, and each person's fair share when the bill is divided across a group. It removes the mental math and awkward rounding from end-of-meal payments.

Who Should Use This Tool?

Diners splitting group meals, service workers checking expected gratuity, travelers adjusting to local tipping norms, and anyone dividing shared costs like taxis, deliveries, or salon services.

Examples

Dinner for Two

Example Input

Bill: $85.00. Tip: 18%. Party: 2 people.

Sample Output

Tip: $15.30. Total with tip: $100.30. Per person: $50.15.

Actionable Use Cases

An $85 dinner with an 18% tip adds $15.30 for a $100.30 total - $50.15 each for two people. Adjust the percentage for service quality, check the per-person share before the check arrives, or compare a pre-tax versus post-tax tip. In countries where tipping is not customary, the tool still works as a pure bill splitter by entering 0%.

How the Calculation Works

Tip amount = bill x tip% / 100. Total = bill + tip. Per-person share = total / party size. For the most standard result, tip on the pre-tax amount; check whether a service charge is already included on the bill before adding one manually.

Common Mistakes and Limitations

Common errors include tipping on tax (inflates the gratuity), missing an auto-gratuity already added for large parties, and splitting uneven orders evenly when individual totals differ widely. The calculator applies one rate to the whole bill; itemized splitting is out of scope.

FAQ

How much should I tip in the US?

15-20% of the pre-tax bill is customary for table service in the United States; 18% is a common middle ground. Counter service, delivery, and other services follow different norms.

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

Tipping on the pre-tax amount is the traditional convention and produces a slightly lower, conservative gratuity. Tipping on the post-tax total is also widely accepted - the difference is usually small.

How does the per-person split work?

The tool adds the tip to the bill and divides the total evenly across the number of people entered. If individuals ordered very different amounts, even splitting may not feel fair - in that case each person can calculate their own share.
