Shared Expense Split Calculator
Split any bill — tip included — in one tap.
How it is calculated
Enter the bill total in dollars, the number of people sharing it and the tip as a percentage of the bill. The tool adds the tip to the bill and divides by the headcount: total with tip = bill × (1 + tip ÷ 100) and per person = total with tip ÷ people. It shows what each person pays, the full total including the tip and the number of people. The tip percentage must be filled in; type 0 if there is no tip, because an empty field gives no result. People must be above zero and the bill cannot be negative. The split is always equal, so it cannot give one person a bigger share. Amounts are rounded to cents, so the shares can differ from the total by a cent.
Worked example
A dinner bill comes to $184.60 for 6 people with a 15% tip. Tip multiplier: 1 + 15 ÷ 100 = 1.15. Total with tip: 184.60 × 1.15 = $212.29. Share per person: 212.29 ÷ 6 = $35.38 (35.3817 rounded). Six shares of $35.38 add up to $212.28, one cent below the total, so someone can round up to cover that cent.
Common mistakes
- Leaving the tip box empty when there is no tip. The tool needs a number, so enter 0.
- Applying the tip to a bill that already includes service charge. Check the receipt first, or the tip is paid twice.
- Counting the wrong number of people, such as leaving out the person who paid or including someone who left early. The share is the total divided by whoever you count.
- Using an equal split when orders were very different. If one person had only a drink, an equal split makes them pay for others' meals.
- Expecting the shares to add up to the total to the cent. Each share is rounded to cents, so a one-cent gap is normal.
About this calculator
Splitting a shared bill evenly means dividing the total cost — plus any tip — by the number of people, so each person pays an identical share regardless of what they individually ordered. It is the simplest and most common way groups settle restaurant checks, shared rides, group gifts, or household bills, trading precision for speed and fairness of a different kind: everyone pays the same amount.

If your group tips on the pre-tax subtotal but the receipt total includes tax, type the full total and convert the tip yourself: divide the tip amount by the full total and enter that as the percentage. An 18 tip on a 100 subtotal with a 120 total is 15 percent here. Do you often split unevenly, say by who ordered more? Tell us how you would want that handled.
