The tip is calculated from the pre-tip bill, then the total is divided equally among the number of people.

Tip and split formulaTotal = Bill × (1 + Tip %) · Per person = Total ÷ People

A practical example

A 20% tip on $86.40 is $17.28. Split between two people, each pays $51.84.

Assumptions, interpretation and common mistakes

Calculation assumptions

  • The tip is a percentage of the entered bill.
  • The bill and tip are split evenly among all people.
  • No person-specific items or different tip shares are modeled.

How to interpret the result

  • Each person pays includes an equal share of bill and tip.
  • Tip amount is the total gratuity for the group.
  • Use the pre-tax subtotal if that matches your local tipping custom.

Common mistakes to avoid

  • Entering zero people or a tip percentage as a decimal.
  • Forgetting that automatic gratuity may already be included.
  • Splitting evenly when diners had substantially different orders.
