Split a bill evenly or proportionally across any number of people.

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. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

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.
