Split Bill Calculator
Split a bill evenly or proportionally across any number of people.
Split any bill among multiple people including tax and tip. Calculate per-person amounts accurately for restaurants, rent, utilities, or shared costs.
What this tool does
This calculator takes a bill amount, tip percentage, and any extra fees, then divides the total across a specified number of people to show what each person owes. The result represents the per-person share when costs are split evenly. The number of people has the most direct impact on the final amount—more people means a lower individual share. The tool works for common scenarios like splitting a restaurant bill among friends, dividing shared expenses at an event, or calculating individual contributions to a group purchase. The calculation assumes equal splits and doesn't account for individual spending variations, separate payment methods, or tax rules that may apply in your location. Results are shown for illustrative purposes to help visualize how costs distribute across a group.

Splitting a bill evenly sounds simple but routinely produces arguments when tip, tax, and extras aren't handled cleanly. This calculator takes the bill total, applies tip percentage (if any), adds extras, and divides by headcount — producing a clean per-person amount everyone can agree.
The math is straightforward: (bill × (1 + tip%)) + extras ÷ people. Useful for restaurants (tip varies by country), flat-shares (proportional splits), group holidays (contributions from multiple people), or any shared expense. For proportional splits (some people owe more than others), calculate each share separately and sum.
How to use it
Input total bill amount, tip percentage (if applicable), any extras to add, and number of people. The tool produces total with tip and per-person amount.
What the result means
Per-person amount is what each person pays to cover their share fairly. Total with tip is what the bill actually costs including tip and extras. Rounding up slightly is considerate if the math produces odd pence figures.
A worked example
Try the defaults: total bill of 120, tip of 10%, extras of 0, number of people of 4. The tool returns 33.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Total Bill, Tip %, Extras, and Number of People.
The formula behind this
Bill plus tip plus extras, divided by number of people. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the bill doesn't show
Standing charges, discounts, and usage tiers all blur the effective rate. The calculation here backs out the total so you're comparing apples to apples across providers, regardless of how each one packages the price.
What this doesn't capture
Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.

Sources & Methodology
Methodology
The calculator computes each person's share by first adding the tip and extras to the original bill amount. The tip is applied as a percentage of the bill, then converted to a currency amount and added to the total. The combined total—bill, tip, and extras—is then divided equally by the number of people to determine each individual's share. The model assumes an even split across all participants and treats the tip as a simple percentage applied to the base bill only, not to extras. It does not account for rounding differences that may occur when splitting indivisible currency units, nor does it model alternative splitting methods such as proportional division based on consumption or income.
