Calculate a tip from the bill and a percentage, then see the total and an even per-person share for any group size.
Example
A 47 bill with a 20% tip adds 9.40, for a total of 56.40. A 100 bill with a 15% tip comes to 115, or 57.50 each for two people, and 84.60 with an 18% tip is 99.83 in total, shown as 33.28 each for three.
Calculation method
The tip is the bill amount multiplied by the tip percentage and divided by 100, and the total is the bill plus that tip. The per-person share divides the total by the number of people, so everyone pays the same share of the bill and the tip. Amounts are shown with up to two decimal places, while the calculation keeps the exact values.
Important notes
Rounded shares may not add back to the total: 99.83 split three ways is exactly 33.276 each, displayed as 33.28, and three payments of 33.28 make 99.84. Whether to tip on the pre-tax subtotal or the final bill, and whether a service charge is already included, depends on local custom.
Choose the amount you want to tip on
Enter the bill amount you want to use as the tip base, the tip percentage and the number of people. A 47 bill with a 20% tip adds 9.40 for a total of 56.40. Local custom decides whether the base is the pre-tax subtotal or the final bill, and whether a service charge already printed on the receipt should be tipped again. If a service charge is listed, compare it with your intended tip before adding more.
Splitting a bill and the leftover cent
The per-person figure divides the bill plus tip evenly. A 100 bill with a 15% tip is 115, or 57.50 each for two people. With three people, 84.60 plus an 18% tip is 99.83 in total, displayed as 33.28 each. Three payments of 33.28 add up to 99.84, one cent more than the total, because the exact share is 33.276. Decide in advance whether one person pays one cent less or everyone rounds up.
When an equal split is not fair
An even split assumes everyone shares the whole bill. If people ordered very different amounts, calculate each person’s own subtotal with the tip percentage instead, or use the Split Bill & Expense Calculator when several people have already paid. For a quick mental check, 10% moves the decimal point one place, so 10% of 100 is 10, and doubling it gives 20%. With three people, 110 appears as 36.67 each, which totals 110.01 when paid separately.
