The Tip Calculator works out the gratuity on a bill, adds it to the subtotal for a grand total, and splits that total evenly across a group. Enter the pre-tip bill amount, the tip percentage you want to leave, and the number of people sharing the check. Each money figure is rounded to the nearest cent, so the numbers match what you would actually hand over at the table.
Formula
tip = bill × (rate / 100); total = bill + tip; perPerson = total / people
- bill
- Bill subtotal before tip
- rate
- Tip percentage (e.g. 18 for 18%)
- people
- Number of people splitting the total
How it works
- Enter the bill amount (before tip), choose or type a tip percentage, and set the number of people splitting the bill.
- The calculator multiplies the bill by the tip rate to get the tip amount, adds it to the bill for the total, then divides the total by the number of people for the per-person share.
- All three outputs — tip, total, and per-person — are rounded to two decimal places (cents).
Worked example
An $80 dinner bill with an 18% tip is split four ways.
- Tip = 80 × (18 ÷ 100) = $14.40.
- Total = 80 + 14.40 = $94.40.
- Per person = 94.40 ÷ 4 = $23.60.
Tip $14.40, total $94.40, and $23.60 per person.
Frequently asked questions
- Is the tip calculated on the pre-tax or post-tax amount?
- The calculator applies the tip percentage to whatever bill figure you enter. Etiquette varies, but tipping on the pre-tax subtotal is common; enter that amount if you prefer to tip on it.
- What is a standard tip percentage in the United States?
- For sit-down restaurant service, 15% to 20% is typical, with 18% to 20% considered good service. Quick counters and takeout often warrant less or none.
- How is the per-person amount rounded?
- The total is divided evenly by the number of people and rounded to the nearest cent. With uneven splits the small rounding remainder means the summed shares can differ from the total by a cent.
- Can I split a bill among any number of people?
- Yes, as long as the number of people is at least one. The total is divided equally, so each diner pays the same share of the combined bill and tip.
