Split Bill Calculator
Split combined bill lines by people, with optional tip percentage.
📖 What it is
The Split Bill Calculator helps you fairly divide a shared bill among friends or family, factoring in any tips you may want to add. This tool is especially useful in social settings where multiple people contribute to a single expense.
To use the calculator, you input the total of all bill lines, specify the tip percentage if desired, and enter the number of people sharing the bill. The calculator then provides the amount each person should pay, ensuring clarity and fairness.
Keep in mind that the tool assumes all individuals are sharing the costs equally. If someone has ordered significantly less or more, you may need to adjust the inputs accordingly. Additionally, ensure all bill items are included, and be cautious about rounding off cents when collecting payments.
How to use
- Enter the amount for each item on the bill.
- Calculate the subtotal by summing all items.

📐 Formulas
- Subtotal—Total of bill lines

- Per Person Share—Grand Total / Number of People
💡 Example
$60 + $40 = $100 subtotal, 10% tip, 4 people -> $27.50 each.
Real-life examples
Dinner with Friends
A bill of $120 with a 15% tip for 4 people results in $34.50 each.
Group Outing
A shared expense of $200 plus a 10% tip among 5 friends means each pays $44.
