Bill Split & Dining Cost Calculator
Work out the complete dining bill and split it between people.
Split the real dining cost
Calculate tip, tax/GST, total and a practical per-person share with optional rounding.

How the Bill Split & Dining Cost Calculator works
The tool calculates gratuity and tax from the entered subtotal, adds them to the bill, then divides the total between the selected number of people.
Calculation breakdown
ToolLott will explain the current inputs and displayed result here.
Bill total and split
Tip = subtotal × tip rate. Tax/GST = subtotal × tax rate. Total = subtotal + tip + tax; per-person share = total ÷ people.
tip amount = bill x tip% / 100The tip percentage is applied to the entered bill amount.
per person = (bill + tip amount) / peopleThis assumes an equal split.
| Symbol / input | Meaning | Unit |
|---|---|---|
bill | Bill before tip | currency |
tip | Tip rate | % |
people | Number of equal shares | people |
Step-by-step method
- Validate the bill, tip percentage and positive number of people.
- Calculate the tip from the bill and selected percentage.
- Add the tip to obtain the total payable amount.
- Divide the total evenly by the party size for the per-person amount.
Worked example
Owen, a operations coordinator, is splitting a $120 restaurant bill between 3 people and wants to include a 15% tip without someone doing the maths at the table.
Example inputs
- bill = 120
- tip = 15
- people = 3
Calculation / processing
15% of 120 = 18 tip.120 + 18 = 138 total.138 / 3 = 46 per person.
The group total is 138 and an equal three-way split is 46 each. The tool does not assign different meal amounts to different people.
Assumptions
- The tip is calculated on the full entered bill amount.
- The total is split equally among all entered people.
Limitations
- Taxes, service charges and uneven individual orders are not separated unless they are already included in the bill amount.
- Local tipping customs and service-charge rules are outside the calculator.
Common questions
Does the calculator split the tip as well as the bill?
Yes. It adds the tip first, then divides the full total by the number of people.
Can I enter zero people?
No. A per-person calculation requires at least one person.
What if everyone owes a different amount?
This tool assumes an equal split; unequal itemised splitting needs a different workflow.
Methodology sources
This page uses basic mathematical or ToolLott implementation logic that does not require an external factual source. The worked result is still tied to the production tool and QA example.

A realistic way Owen could use this tool
Owen is a operations coordinator.
Owen is splitting a $120 restaurant bill between 3 people and wants to include a 15% tip without someone doing the maths at the table.
They use the worked values shown in the tool: Bill amount: 120; Tip (%): 15; Number of people: 3.
ToolLott returns “Total: 138”. That gives Owen a concrete figure to check against the real task before they copy it into the next document or decision.
Fictional scenario using realistic example data. For Ready tools, the worked result is tied to the tested example shown in the tool. Replace the figures with your own inputs and independently verify important professional, financial, legal, health or safety decisions.
