How it works

Enter your bill amount, choose a typical tip percentage (for example 15%, 18%, or 20%), and optionally how many people are paying. The tool shows the tip in the same currency as your bill, the full total including gratuity, and each person’s share when you split evenly.


The Formula
Tip = bill × (tipPercent ÷ 100)
Total = bill + tip
Per person = total ÷ partySize

Worked Example
  1. Quick restaurant example

    Bill £48.60 with 18% tip: tip = 48.60 × 0.18 = £8.75 (rounded to pence), total = £57.35. For 3 people splitting evenly, about £19.12 each. The same numbers apply in dollars for a $48.60 bill.


Tips, Assumptions & Limitations
  • Common sit-down ranges are about 15–20% of the pre-tax bill in many US/UK contexts; adjust to what you choose.
  • If you only know the post-tax total, enter that as the bill so the percentage matches what you intend.
  • Party size must be a whole number; the split assumes an even divide, not itemised orders.
FAQ

Multiply the bill by the tip percentage expressed as a decimal. For example, 18% means multiply by 0.18. This tool does that multiplication and rounds to two decimal places for currency-style totals.

People use different conventions. Enter whichever bill total you want the percentage applied to—if you tip on the pre-tax subtotal, type that amount; if you prefer the after-tax figure, type that instead.

Yes. Enter the number of people sharing; the calculator divides the bill-plus-tip total evenly. It does not model separate items or uneven shares.

No currency conversion or tax rules are applied. Amounts stay in whichever currency you typed, for educational arithmetic only.
