How the tip & bill split calculator works
Calculate a tip on the pre-tax bill, add sales tax, and split the final total fairly with cent-accurate shares.
Total = bill + tip on bill + tax on bill. Divide the total cents among the people, giving any remaining cents to one person at a time.
Read our calculation methodology and limitations.
Example
A $100 bill with a 20% tip and 7% tax totals $127. Split three ways, one person pays $42.34 and two pay $42.33.
What affects the result
- Tip and tax both use the pre-tax bill.
- The number of people must be a positive whole number.
- Check whether gratuity or a service charge is already included.
Frequently asked questions
Is the tip calculated before or after tax?
Before tax. Enter the pre-tax bill and the tax rate separately.
Why can one person pay a cent more?
Some totals cannot split equally into whole cents. Distributing the remainder makes the payments add up exactly.
