Basics

How tip calculation works

Bill amount

The bill amount is the base restaurant or service charge before optional tax and tip settings.

Tip percentage

The tip percentage determines how much extra is added to the selected tip base.

Total bill

Total bill includes bill amount, tax, service charge, and calculated tip.

Per-person split

Per-person total divides the final bill by the number of people.

Comparison

Tipping before tax vs after tax

Tip before tax

Uses the bill subtotal before tax as the tip base. Some people prefer this because tax is not part of service cost.

Tip after tax

Uses bill plus tax as the tip base. This often produces a slightly higher tip when tax is entered.

Formula

Tip formula explanation

Tip amount

Tip = Tip Base × Tip Percentage

The tip base is either the bill before tax or the bill plus tax, depending on your selection.

Total bill

Total = Bill + Tax + Service Charge + Tip

This is the final amount to pay before splitting between people.

Per-person amount

Per Person = Total ÷ Number of People

This divides the total bill evenly across the number of people entered.
