Choose a percentage, then see the tip, total, and equal share.

Method and inputs
Enter a positive bill amount B, a tip percentage P of zero or more, and a whole-number count N of at least one person. The tip is B × P ÷ 100; the total is B + tip; and the equal share is total ÷ N. The percentage applies to the amount entered, with no automatic tax adjustment.
The preset percentage buttons only fill the editable P field. Pick the percentage appropriate to your own situation.
Worked example
For a $50.00 bill, a chosen 18% tip, and two people: tip = $50.00 × 18 ÷ 100 = $9.00. Total = $50.00 + $9.00 = $59.00. Each person pays $29.50, including $4.50 of the tip. These are the values displayed by the calculator for those inputs.
Equal split and rounding
The calculator divides the entire total equally. It does not track individual orders, discounts, tax lines, service charges, or uneven contributions. If a charge already includes a tip, account for it in the bill or percentage you enter to avoid adding it twice.
Results are displayed to two decimal places. For example, a $10.00 total split three ways displays $3.33 per person; three rounded payments total $9.99, so one person would need to pay the remaining cent.
Assumptions and related tools
This is arithmetic for a user-selected percentage. It does not determine whether a tip is expected, required, or appropriate in any location or service setting.
For the underlying percentage operation, use the percentage calculator. To convert a fraction of a bill into a percentage, use the fraction-to-percent calculator.
Frequently Asked Questions
Which bill amount does the percentage use?
It uses exactly the bill amount you enter. To base the tip on a subtotal before tax or a total including tax, enter that amount yourself.
Does the split assign different items to different people?
No. It divides the bill plus tip equally by the whole-number people count. Calculate separate shares outside this tool if orders differ.
Why can rounded individual payments miss the displayed total?
The calculation keeps unrounded values and displays money to two decimals. Rounding each person's share can leave a cent difference; assign any remainder explicitly when paying.
Do the preset percentages state what I must tip?
No. They are editable calculation shortcuts, not local customs, legal requirements, or a recommendation.
