Tip Calculator and Bill Splitter
Work out the tip, the total and what each person owes. Tip on the pre-tax amount if you prefer, and round up so nobody has to deal with cents.
How it works
How the tip is calculated
Tip = bill × tip % ÷ 100. Total = bill + tip. Per person = total ÷ number of people.
If you choose tip on pre-tax amount, enter the sales tax shown on your check and the tip is worked out on the bill minus that tax. On a $108.88 check that includes $8.88 tax, a 20% tip on the pre-tax $100.00 is $20.00, compared with $21.78 on the full amount.
Splitting evenly
Money only divides to the cent, so an even split sometimes leaves a cent or two over. A $100 check with a 15% tip comes to $115.00; split three ways that is $38.33 each with one cent left, so one person pays $38.34. The calculator tells you when this happens. Turn on round up and everyone pays a whole-dollar amount instead, with the extra added to the tip: $39 each, a $17 tip.
How much to tip
Tipping in the United States is a custom, not a rule, and amounts vary by place and service. The preset buttons (15, 18, 20 and 25%) are common choices for table service; they are suggestions, not a standard. Check whether a service charge or gratuity has already been added, which is common for larger groups.
Common questions
Should I tip on the amount before or after tax?
Either is common. Tipping on the pre-tax amount is slightly cheaper; the difference on a $100 meal with 8% tax at 20% is $1.60. Use the pre-tax option if that is your habit.
What if a gratuity is already on the check?
If the check shows an automatic gratuity or service charge, that is usually the tip. Read the check before adding more.
Why does one person pay a cent more?
Some totals cannot be divided exactly into cents. The calculator shows the even share and how many people need to add one cent so the total is covered.
