Tip Calculator
Work out the tip, total bill, and per-person split for any check.
How to use this calculator
- Enter the pre-tip bill amount.
- Choose the tip percentage.
- Enter how many people are splitting, and calculate.
The formula
Tip = Bill × (Tip % ÷ 100) Total = Bill + Tip Per person = Total ÷ People- Bill
- The check amount before tip
- Tip %
- Your chosen gratuity rate
How it works
The tip is a straight percentage of the bill. 18% of $86.40 is 86.40 × 0.18 = $15.55.
Splitting divides the tip-inclusive total evenly; rounding to cents happens only at display time, so the per-person figure is exact.
Worked example
An $86.40 dinner check, 18% tip, split 3 ways.
- 1Tip = 86.40 × 0.18 = 15.55
- 2Total = 86.40 + 15.55 = 101.95
- 3101.95 ÷ 3 ≈ 33.98
Tip $15.55, total $101.95, about $33.98 per person.

Frequently asked questions
Should I tip on the pre-tax or post-tax amount?
Customs differ; many people tip on the pre-tax subtotal. Enter whichever base you prefer — the math is the same.
How do I round the total to a whole number?
Adjust the percentage until the total lands where you want — each 1% on a $50 bill is $0.50.
