Calculating a tip is simple. The standard formula is: Tip Amount = Bill Amount × (Tip Percentage / 100). For example, to calculate a 20% tip on a $50 bill: $50 × 0.20 = $10. The total would be $60.

Should you tip on tax?
Generally, etiquette suggests calculating the tip on the pre-tax subtotal. However, many people choose to tip on the total amount including tax for simplicity or generosity. Our calculator allows you to easily calculate based on your total bill input.
How to Split the Bill
Splitting the bill can be done in several ways:
- Equal Split: Divide the total bill (including tip) by the number of people.
- Percentage Split: Assign a percentage of the bill to each person based on what they ordered.
- Itemized Split: Each person pays exactly for what they ordered plus their share of tax and tip.
